    A quick project for tracking basic data during flight. This is a garage project I made out of own curiosity. Not tested in flight yet, if you decide to do it you're doing it at your own risk. There are advanced solutions on the market like Dekunu One or Aon X2 and if you can afford them I encourage you to use professionally made equipment. You'd need: * Car GPS speedometer (I used this one because its shape and size are already almost snag-free: https://www.aliexpress.com/item/4000265066382.html * Powerbank (with least capacity and smallest size possible - in the prototype this one was used: https://www.aliexpress.com/item/32945597181.html ) * 850 mAh battery (ideally 2000 mAh, but unlikely they'll fit inside the case) * Small switch Assembly is pretty straightforward: unsolder USB ports on both GPS and powerbank, solder switch and battery. Additionally I flipped the capacitor (it's under white tape on the first photo) - put it on the opposite site of the board to give some room for powerbank's charger. The device is mounted on a rig using velcro strap with a loop. So far I tested it on the ground on a bike and the speed is pretty accurate - +/- 1 km/h to what smartphone GPS shows Even with 850 mAh battery the device help up for around 8-10 hours (screen constantly on) which is quite impressed actually. Talking about the battery - attentive reader might notice that it got swollen - probably because powerbank's changer is for 2000 mAh, while battery is 850 mAh. That's a critical flaw because swollen battery has high risk of explosion as pressure changes during climb to the altitude. If I ever decide to use it for actual tests, the batteries will be replaced with non-chargeable lithium batteries just like in audibles (powerbank's module would still nicely convert that into a constant 5V supply). Meanwhile I'm doing some more research to find safe chargeable batteries. Now, what this thing can do: * Display current ground speed (both metric and those other, inferior units). Speed alarm can be set at as high as 200 km/h, so I'd assume device can measure at lease that much * Display one of 8 directions ( N/NE/E/SE and so on) - yeah, it's pretty basic, but better than nothing * Display distance covered, accuracy 100m * Display few other stats, but those are useless for WS flying * Oh, yeah, you can change colors Again, this is a garage project. I'm only sharing the fruits of my curiosity and taking no responsibility for what you might do with it.

    So if you're a random tooled up white guy patrolling the streets with an assault rifle and tactical gear the cops are happy to have you around and grateful for the help. If you're a female paramedic with a med kit you're clearly dangerous and untrustworthy and must be violently removed from the scene. In 30 years time this descent into officially sanctioned armed factionalism is what the history classes will be teaching about the Trump presidency.

    How can we support protests while condemning riots? Is there a well-defined line besides the already-stated “looting and burning are unacceptable?” Or do the protests have to stop until the “leaders” can control every.last.protester? Because if so, then the right (that completely monolithic entity with no internal differences) owns every single racist, and they define it, just as so many on the right insist that the looters define the left. Each of us has a responsibility; not to wait for the other side to be our definition of perfect, but to help to define what we want for our country. Wendy P.

    Protecting does not equal shooting people in the back. Yes, you do. If you shoot someone during the commission of a crime you can't claim self defense. Once you condemn every act of murder a criminal performs, and not give him a break because he's white and supports your candidate, we might take you seriously. Until then, support of murderers while condemning rioting is the height of hypocrisy.

    As a load organizer I'm partially responsible for the safety of the group. I'll do a 2-way with anyone. When someone wants to jump with my group, yes, I need to know their capabilities. Sometimes we'll break into smaller groups to accommodate those with lower skills. When that person says, "but I wanted to do 8-way", but they can't do consistent 4-way, that shows that they don't understand all the factors involved with these decisions, and don't respect the other jumpers. When I ask folks what slot they feel comfortable in and they say, "I can do anything" that's a big red flag. They get placed in or close to the base until we learn what they can really do. I've taken lesser experienced jumpers on bigger ways. They were jumpers I've jumped with, and I knew what they could and couldn't do. They get slotted in a place where they can be successful and the group isn't negatively impacted or safety compromised. They enjoy the jump, do well, learn and are gracious. Sharing a handshake or hug, and a thanks goes a long way. That gets them on the next jump. Being an LO is fun, but it's work and can be a PIA. And if I'm paying for jump it's an extra PIA. Be nice. Three goals: have fun, help others learn in a controlled fashion, and have everyone go home whole.

    Well, at 35 seconds, where he zooms under the student, he was being dangerous. His inability to control his fall rate or position in the sky relative to the student is dangerous. The video is of a single jumpmaster, harness hold exit, student jump. That's an AFF Level 4 type jump. His skills were not even close to being up to the task of helping or saving the student. That is dangerous.

    Summer USPA BOD Meeting - September 18-20, 2020 The USPA Board of Directors held its Summer meeting in Nashville, Tennessee, September 18-20. The board meeting was broadcast live via Zoom Webinar for any USPA members who wanted to observe and watch our deliberations. The BOD foresees that his may be a venue for future meetings. 1. Due to the recent pandemic membership, licenses and ratings were down as expected but they are slowly rebounding. 2. The S&T felt that there needed to be more clarity and defined criteria for the BSR 2-1.G.6.a. on who can supervise a Coach or a D licensed skydiver when jumping with students in a group. - The new wording will be a. Student freefall training for group freefall jumps must be conducted by either a USPA Coach or a D-License holder approved to make coach jumps by their S&TA, under the supervision of a USPA Instructor 3. The S&T revisited the D License requirements and made some adjustments for the members to meet the criteria. The original intent of the previous change was to allow the D license applicant to choose or complete 2 of either of the listed items outline in section 3-1. The S&T committee made necessary adjustments to reflect the needed changes. - Move to change SIM section 3-1.E.D LICENSE.1.C. to read: “Completed two of the following requirements (a requirement can be repeated): 1. night jump (following the SIM recommendations) 2. landed within seven feet of the target center on 100 jumps 3. participated in a canopy formation of a 3 stack or larger completing a full rotation. 4. completed an intentional water jump 5. successful completion of one hundred formation skydives, at least twenty-five of which must involve at least eight participants.” 4. The S&T committee decided to change the renewal criteria for expired rating holders over 2 years and for foreign rating holders who wish to challenge the course for certification. The new criteria is for them is to attend a full course to include all the air evaluations and ground preps. 5. The S&T committee discussed the merits of having an expired IE still have signature authority for USPA renewals and licenses. The committee felt that this was a venue that would serve the membership if the expired IE was still skydiving and kept their instructor ratings current in that discipline and was still relevant. This change will be reflected in the next addition of the IRM. 6. Coaches will soon have verification blocks they can sign on the 2-page A-license card to mirror the signature authority they have on the 4-page A-license card. 7. Regional Directors are now able to renew ratings up to 15 days expired for special or extenuating circumstances. A $40 expired rating renewal fee may apply. 8. The S&T committee developed a sub-committee to assist in developing a military proficiency certificate for servicemen and women who have completed military free fall schools and still want to continue skydiving at USPA GM drop zones. 9. USPA will be listing the medical type, i.e. FAA, Military, or Foreign, in credential verification lookup. This will assist and help DZO’s ensure that the tandem instructors working at the drop zones meet the BSR requirements. 10. The committee established rating renewal requirements for PRO rated holders. If they are have expired from 12-24 months, they will have to do two stand-up landings, making the first contact and stopping within an area 40 feet long by 20 feet wide: fortheir respective wing loadings of 1.5:1 (Lower & Higher), in the presence of a current Regional, National, or U.S./FAI International Judge; Regional or National Director; S&TA, or IE. 11. For Tandem IE candidates who wish to achieve the USPA Tandem IE rating, out of the 25 air and ground evaluations that are required – 15 of them need to be focused on Category A and B jumps and group evaluations. Candidates will have to list these on their respective vetting sheets. 12. The S&T committee tasked a sub-committee to research and define recommendations for angle jumps and tracking jumps that could be added to USPA SIM Section 6-2. These recommendations will be brought to the committee for review. 13. To assist Drop Zones where additional proctoring personnel are needed, USPA Judges will now be able to administer the A, B, and C License tests and USPA Judge Examiners can administer the D License test. 14. Other Meeting highlights include: - The USPA board of Directors worked on a values statement and an online code of conduct. Pending final adoption, these statements will be released soon. - Your primary membership card is currently available in your USPA profile for download and printing. If you would like a physical card mailed to you upon joining, renewing, or adding a license or rating, please ensure your individual settings reflect that preference. - The board awarded the following USPA service awards - The USPA Gold Medal for Meritorious Service to Kurt Gaebel, D-18635 & Yong Chisholm, D-21693. - After 24 years of service for USPA, Executive Director Ed Scott attended his 48th and final board meeting. President Chuck Akers presented Ed with a plaque from board and staff commemorating his dedication. A full report will appear in the November issue of Parachutist. The board will meet next January 29-31, 2021 in Cincinnati, Ohio.

    It's an indictment of the system that the political party of judges should have any effect on the the legal decisions they make. That's the stuff of Banana Republics.

    The instructors who have helped you back, ask them to watch a few of your landings and give you some advice on gear that may be suitable. Good used gear is a cheaper approach and allows you to gain experience before committing bigger bucks to more long term gear. This gear can often be sold on to fellow newer jumpers looking for 1st gear when your ready to downsize. Dont be in a rush to downsize.

    Just - wow. Using presidential powers to protect an enemy of the US who is attacking the electoral process, because it might benefit the president. There's a word for that. LONDON—Lawyers representing the United States at Julian Assange’s extradition trial in Britain have accepted the claim that the WikiLeaks founder was offered a presidential pardon by a Congressman on the condition that he would help cover up Russia’s involvement in hacking emails from the Democratic National Committee. Jennifer Robinson, a lawyer, told the court that she had attended a meeting between Assange, then Republican Congressman Dana Rohrabacher, and pro-Trump troll Charles Johnson at Assange’s hide-out, the Ecuadorian embassy in London, on August 15, 2017. https://www.thedailybeast.com/us-admits-that-putins-favorite-congressman-offered-pardon-to-assange-if-he-covered-up-russia-links

    tunnel went very well. the coach said my heading and turns were very good and only recommendation was to be more aggressive in my moves since I tend to be slow and cautious. side slide needs a bit of work still. We played a game of tag at his suggestion. Turns out I was almost perfect doing that because I was relaxed and just flying and not overthinking everything. I was either having a bad day or the sensory and task overload got me. I am ready to go try again this weekend.

    Some interesting, if not fishy information here. That gear is from an estate sale? Well, that gear looks familiar to me, and the person I think it may belong to, as far as I know, is not dead. That gear may be stolen. (The name on the log book is not familiar to me.) Also, a 'first jump' in '02 is not consistent with licenses issued in '59-'61. Might be time for a couple phone calls...

    Found this really interesting mini project on YT where each canopy line tension is measured during flight while performing different type of maneuvers. Wonder if this has already be done for skydiving canopies by some manufacturers? If not, you think it could be beneficial?

    Hi 4470, The Vector & the Infinity are the only two rigs that I know of that use 500d Cordura as standard. However, both will build you a rig in the 1,000d Cordura if requested. Jerry Baumchen PS) IMO the Infinity MARD, when compared to the SkyHook, is a far simpler system; and just, if not more, reliable.

    Yes seriously. If they save $30 a week (less than 10% of their salary) it is paid off in 5 years. Which is much better than being dead. And is much better than $400,000. However, if the plight of the poor outrages you, feel free to help out. Or better yet campaign for single payer.

    Oh my. That's some seriously old gear. Forget about what 'new ones cost'. Also, forget about C/L. Classifieds on here or some of the FB groups would be a much better place. As far as the rigs go: You need to find out when they were last repacked. There should be a packing data card, it should be in a little pocket on the back of the label with the serial number on it (I think). That will tell you what reserve is in it and when it was last inspected & repacked. How many packs are on it (that matters) And who did it. You'd have to open up the main containers to see what main canopy is in it. Depending on the mains, there might be some value. But not a whole lot. There are a lot of riggers out there who won't pack or work on gear that old. However, you might find a newer jumper or a beginning camera flyer who would want one for a turn rig. Maybe. The altimeter might be worth a bit. Most of the kids these days go for digital, but some of the 'crusty old guys' prefer analog. The chest mount pillow is popular for wingsuiting. The Astra & Time Out are obsolete. Interesting conversation pieces. Same with the camera. Is that a Digital Video Tape unit? The lens might be worth a couple bucks, depending on quality. Helmets are likely junk. Nobody will want to wear them. Not sure about the sights & mounts. Those might be worth a couple bucks. Suits might be worth something (not a lot), if they are in good shape. If the material is worn or rotting (more likely rotting), then not. The problem with used suits (and the reason new ones cost so much) is that they are custom made to fit the buyer. Finding a buyer for a used suit depends on finding someone it fits well. The log book should have some dates and the name of the owner in it. I don't know if you'd find anyone to buy it. Kinda creepy. If you aren't a jumper (sounds like it), it might be worth your while to take all this out to a DZ and see what they say. Are you in the LA area? Perris has a big gear store, and they'd be able to tell you what you have for canopies and all of that. They might give you an offer (lowish), offer to sell it on consignment (for a fee) or tell you to toss it in the garbage. I hope you didn't pay much for it. I can't see it being worth more than a few hundred (total for the entire group).

    There's an easy way to figure that out. Just take the George Floyd challenge. Remain stone cold sober and have someone kneel on your neck for 8 minutes and 46 seconds. Be sure that you are breathing normally before conducting this test so you can avoid any uncertainty as to the results.

    No he is not. I totally agree, but you knew I would. I simply admire his tenacity to continue dealing with you people. The agenda of the left includes instituting scientific socialism. The intellectual elite have determined that they know what is best for all Americans based their data obtained through mathematics, statistical algorithms, and agreed upon by the like-minded. This is a resurgence of the strategy implemented by McNamara and LBJ to manage the Vietnam War. It will produce a similar outcome now. Years of violence, cultural war, and the breakdown of the Republic for the benefit of those intellectual power mongers. They will have the wealth and the rest of us will live in fear. The rioters are paid for by those that will profit from their lawlessness in the hoped for long run. That is the Luciferian concept. Man will rule above God. We will not let that happen. Liberty is worth fighting for. That is part of the American creed, always has been and always will be.

    Given that I am answering a post that includes "stink'n think'n" "intellectual dishonesty "aggro arrogance" "mental masturbation" "your bitter" "regressive Dictatorship" "A fool and his money" - that's some funny stuff right there. If you look at it objectively, right wing terrorism is a far bigger problem in the US than left wing rioters. I suspect that even you would prefer your store to be vandalized than to be killed. "Both are bad!" - Absolutely. For the solution to that I refer to a guy who was a lot better at this than I could ever be: "It is as necessary for me to be as vigorous in condemning the conditions which cause persons to feel that they must engage in riotous activities as it is for me to condemn riots. I think America must see that riots do not develop out of thin air. Certain conditions continue to exist in our society which must be condemned as vigorously as we condemn riots. But in the final analysis, a riot is the language of the unheard. And what is it that America has failed to hear? It has failed to hear that the plight of the Negro poor has worsened over the last few years. It has failed to hear that the promises of freedom and justice have not been met. And it has failed to hear that large segments of white society are more concerned about tranquility and the status quo than about justice, equality, and humanity. And so in a real sense our nation's summers of riots are caused by our nation's winters of delay. And as long as America postpones justice, we stand in the position of having these recurrences of violence and riots over and over again. Social justice and progress are the absolute guarantors of riot prevention." So there's your answer - if you want one.

    Bullshit. You applauded him for being there doing what he was doing, you said everyone should be there doing what he was doing, and you've said the shootings were only in self defence and were the fault of the people who were shot. In what way do you not support him shooting people? Says who? I have not seen any indication of that. Eyewitnesses have said the catalyst for the first shooting was Rittenhouse holding a black man at gunpoint who was trying to get into his own car because Rittenhouse assumed he was trying to steal it. The man who confronted him him about it - the first man he murdered - was unarmed. This chain of events is all Rittenhouse's fault, is a predictable consequence of untrained fantasist wannabe's inserting themselves into tense situations and will keep happening if more people head out thre to do what you want them to do. When trying to stop a heavily armed man who has just murdered someone? Sure, of course you believe that when trying to stop a murderer with an assault rifle you would not use the only makeshift weapon at your disposal. You're strong enough to take on 6 cops at once and save George Floyds life, I'm sure you could have just strolled up to Rittenhouse and taken his rifle away with one arm tied behind your back. WHO proved they were criminals and arsonists? Was anyone that Rittnhouse shot involved in that crime and arson or are you just smearing their memories in order to protect your political stance? Your reasoning is that a dumpster fire was set in Kenosha, therefore everyone out in Kenosha that night was an arsonist, therefore it was cool for Rittenhouse to shoot whoever. It's abhorrent. Consider this - while Rittenhouse was running around lying about being an EMT, Grosskreutz was an actual EMT who had been treating numerous people throughout the night and who never shot anyone. Yet you slander him as a violent looting arsonist who Rittenhouse was totally ok to shoot. Just think, he's a real person. It's despicable the lengths you are going to to dehumanise him and the other victims - with zero evidence - as nothing more than a pack of arsonists and looters just so you can defend your precious right wing militia. The police had already publicly and visibly abdicated their responsibility to deal with the armed right wing mobs roaming Kenosha. Many protesters had seen the police not just allowing the mobs to stay in curfewed areas while they were moved on, but thanking them and actively aiding them. Add to that the mob the Rittenhouse was in bragging that police were funnelling protestors towards them to 'deal with' and you can understand why they may not have felt the police would deal with him. And oh yeah I forgot... they were right. The police didn't deal with him. A running man with a rifle after multiple gunshots had been heard, followed by people shouting that he had shot someone and they just let him straight through. Free and clear to do whatever else he wanted that night. That's how the police dealt with the most serious crime which occurred that night.

    Yep, he will only condemn the people with guns who travelled to Kenosha specifically so they could confront protestors if they attack a protestor completely out of the blue with no provocation. He’ll condemn any of the protesters - all of whom he lumps in with arsonists and vandals - for anything they do even in self defence.

    Turtle, again, if the kid in question had been African-American, dressed in a hoodie, at the Charlottesville rally, maybe in the moments after the guy ran his car into the crowd and killing Heather Heyer, what would your reaction have been? Honestly? The police are just as much there to protect the citizens of Minneapolis, including the violent ones, as they are there to protect the businesses of people with money. They are also there to protect visitors to the city. Allowing the kid to run away, not "automatically reacting to a perceived threat," because the kid was white, is exactly what the protests are about. A knife on the floor of the car (i.e. not in his hands) was stated as a threat worthy of shooting Jacob Blake because he didn't immediately turn around and comply. Shots, a person running with a gun, and people pointing at him and saying "he's killed someone" is not a threat even worthy of stopping the guy. That's fucking bullshit. Wendy P.

    Never thought my first forum post on DZ would be about jumping with dolphins... Anyway recently I did a clear & pull on the back of an inflatable dolphin and riding it down on the back. I exited at 6000 feet and we allready lost some weight earlier.. So there was just one other jumper left behind me and I had all the space.. I was able to get out facing the prop hugging the dolphin with it's tail clamped between my legs and choking the neck of the dolphin with my left arm (no worries it's not a living animal). The pilot was flying with almost zero prop and still it was one hell of a fight in the door. Somehow I was able to make a sort of stable exit and pull my pilot.. On opening I got a bit on the side because the dolphin got air.. While flying down the density is increasing which makes the dolphin deflates and this makes it harder to clamp the dolphin. So looking at your plan... I would say that making a dive exit the way you describe it...impossible unless it's a tiny dolphin. The dolphin will get air and unless you have strong arms and are some tunnel ninja you will be unable to fall stable. Please stay safe!

    I am a wingsuit coach and did first flight courses for around 40 students until today. Some have exactly 201 and perform very well, while others with the same jump number struggle. Same goes for more experienced people, there is no guarantee that it will work out better just because somebody has more jumps. Being current plays more into account, having 30 jumps in the last 2 months is better than having 1000 jumps over 20 years and only 10 jumps in the last months. I would not worry too much about that, if you don't rock the first jump, just retry and do another one with your coach.

    You've gotten some good answers, but here are a couple more: I'll jump with anyone, regardless of experience. I've said it a zillion times - my only requirement is that you not try to kill me. But I need to know what that experience is. I need to decide if you can safely join the group I'm with or how to build a group and dive plan that has a reasonable chance of succeeding and that will be safe(ish). The only real metrics for that experience is jump numbers, and to a certain degree, tunnel time (see post #6 for why tunnel time is not a full replacement). As was also noted in post #6, being a part of the community is also part of it. Show up on a regular basis. Jump with folks. When they get to know you and your skill level, the chances of getting invited on fun stuff goes up. I've seen 40-50 jump new folk invited on bigish (12 or so) hybrids because the guys putting the plan together knew that the new guy could make a stable exit and lay the base for a hybrid. Not a super challenging or exciting slot, but it gave the new guy a chance to be on a fun jump, show he could do what was needed and gain some experience. Hang out after jumping (you don't have to drink). Make friends so you aren't just 'the new guy'. And, the hardest part, be patient. It takes time to build kills & experience. But if you show those around you that you aren't going to do stuff beyond what you should, show them that you have a good handle on what you can & can't do, that you have some good judgement, you will have a better chance of becoming a part of the 'cool kids'. Don't be 'that guy'. Don't be Mr Madd Skillz. I know a couple guys who have earned a reputation for being stupid and dangerous. For some strange reason, they have a hard time finding people to jump with. There will always be a few that look down on you because you're new. But my experience is that they are far, far more the exception than the rule.

    Oh come on. Unless you are hoping for dick picks why don't you just share it with all of us? (And you can share those dick pics by pm if you want) Fwiw to the OP, the transition from dive to level before the flare works best if it's done smooth and slow. Put the earphones in that flysight set to ping you the speed, and work on levelling and staying level without losing speed. More often than not a too quick levelling just causes a lot of drag due to changing the angle of attack too much, when at that stage you want to change pitch while maintaining the AoA as much as possible.

    I doubt it's ALWAYS riser covers causing hard openings, rather that they can be the explanation for more or less frequent hard openings (you can obviously easily cause a hard opening on any riser covers by leaving the slider down on packing). Here's the Bill Booth briefly talking a bit about this (35m17s to 37m17s):

    ????? The idiot instructor did everything wrong except not leave the aircraft. The student was basically looking good. A little in person coaching from someone with more fall rate and body control than the student would have turned this jump into a huge success. Yes, the instructor did gobs of things that were dangerous. I got my AFF rating in 1988. I've done more AFF than most people have jumps. I'm telling you, based on my actual experience, this was horrible.

    He had a reserve handle, right? Why didn't he pull that? The AAD fire had nothing to do with the instructor, unless that instructor trained him and neglected to talk about that. By level 3, a student should be able pull their own reserve if they can't find the main handle, and they should know what to do if an instructor isn't there at pull time. Shit happens, I signed the waiver, it's on me to save my own life.
