Not in my wildest dreams would I see a LiveTime tech video on this channel! Awesome! Might have been handy to mention the TimeTable. Keeps the race going fast and very useful if you have over 30 racers. I want to buy one of those DIY timers :)
Do you know if there is any version of open source firmware for the laprf 8way? Because it doesn't work properly with the DJI system and Immersion discontinued support for LAPRF 8WAY. Thing that does not speak well of Immersion. We stop using Delta 5 to buy immersion and they discontinue support.
Having experienced the other timing systems along with Geoff I can say wow! The IRC system is great. So glad to have it for timing now. Some people say it’s overpriced but given how nice it is and how much work and money went into development I believe it’s a great value
hey joshua, i just got the bardwell f4 fc that i brought not so long ago. i am right now pre soldering the board up for the esc. Question, what vtx would you recommend, because i have vtx but it takes 12v to power it up. and also the rx i have is fs-ia6b, and i was wondering if it would work on this board. thanks alot, lots of video help. wondering if you could help me with this.
FSia6b has SBUS output if my memory serves, so no problem. For vTX check out the FPV section of my web site: www.fpvknowitall.com/ultimate-fpv-shopping-list/
Wow I really love that there's the build-it-yourself route for *that* much cheaper... That's the skill I love most getting through this hobby: buy cheap and mcguyver something together yourself^^
Plug in and go...not happening for me. Been looking through TH-cam trying to figure out how to just get the thing to talk with my computer. Beyond frustrating!
i thought about the same thing. This is the the single lab-timer (the modules can be chained together): github.com/voroshkov/Chorus-RF-Laptimer#rx5808-spi-patch-required this is a more advanced timer, that work with LiveTime. github.com/scottgchin/delta5_race_timer I think somebody could make something similar to the delta 5 with an ESP32 but way cheaper, and a little smaller. and then have the receiver moules directly connected to the ESP32. but its just an idea. i also thought about a mesh of esp8266.
I just ordered an extra RX5808, when it arrives I'll hook it up and get coding! Did some code reading, looks easy enough to port as it is using some very rudimentary bit banging :p Adding a comperator, a shift register and some transistors to drive an interrupt; could eliminate using multiple Arduinos for example...
There is no difference, but price, for a mesh of ESP32/8266's. I'm waiting for the RX5808 to arrive, but I can see a couple of possible improvements. Right now the main loop is reading RSSI repeatedly, which could be cylced using a comperator and interrupt feeding an array. Maybe I just hate having code in the main loop()... Nested if statements also grind my gears.
Sjoer van der Ploeg sounds really interesting, I would love to see a rough diagram/idea. I do like a more analog hardware oriented approach rather than having 8 MCUs. But how will you make your reference voltage for the comparator?
For a serious event I wouldn't use it with more than 1 pilot. You can get by with 2 pilots on the puck, but I've had lots of issues trying to use 3 pilots with the puck. It's nowhere sensitive enough with fast pilots. Personally I just built a Delta5 for slightly more than the cost of the puck and I can run 8 pilots with dedicated timers no problem.
Neat stuff! HEYi was wondering, Legalities as they are. I was wanting to know if you have a video for "how to get your HAM licence step by step or a resource list for that subject. I have to admit i haven't researched all you vids or checked FPV KIA site. What i found is it is a much more elusive hobbie than FPV and everything is set up for people who really want to talk to china on low band LOL
Wanna opensource? Google this solution for laptimer Chorus-RF-Laptimer at github. Cheap to build and works via video TX as well. Our community in Belarus uses it on their tournaments.
The big advantage of the IRC system is that it is almost zero maintenance, zero setup. You can tweak the sensitivity slightly for the environment if you are getting missed reads or false reads but other than that, it is 100% plug and go. Geoff is a massive nerd when it comes to this stuff and if anybody can get this working he can, but he still struggled and struggled to get consistent results out of the Delta 5. Especially if you are running serious events, you don't have time to be screwing around like that, and you can't afford to have mistakes. So there are people out there for whom the additional cost is worth it.
Same for other systems, you make right box, shielded, and you never have to worry about tuning stuff again. But IRC is a great tool. Also other system will work with lifeTime also (not delta5, although it works also). Great practical video!
One of my local guys is working on an open system (wizard tracker) that doesnt need calibration with all data available for post race analysis. The open systems are great for the diy interest folk, but they are not as easy to use. Open source was out plan for the racing scene after using the tbs kit and having nothing but trouble with calibration and misses. But the laprf puck just worked, so we now use the laprf8, as there's little to no setup required. Im still hopeful we can finish the wizard, but for all it can add, it won't be much use without integration into livetime or an alternative open source management tool. Ps on the over priced, laprf is not far off half the price of the tbs unit.
Save your time on the TBS one. It is a complete waste of money. Our Louisville chapter uses one and it double counts/doesn't all the time. Complete waste of money!
Also both of you guys look so natural. Great work on the lighting Joshua!
We run 4 pilots on the puck and the app works great. Only issue is the last lap. Great review!
nice video bud. i did learn something today. i was thinking i needed a transponder like racing onroad rc cars

Do I need to buy it where I find it?
Man, it would be great if we had something like that here in Brazil... Maybe we even have and I don't know yet, who knows.
is that a 4S4P 18650 cell battery? does it last the whole flying session (5-7 hrs?)
how much current does the lapRF draw?
You would have to ask Geoff about that, as he is the custodian of the machine.
i C U Barfwells! lol. I appreciate the thorough analysis, our club (Jacksonville, NC) has been wrestling with lap timing gear.
CHorus RF is a really really nice DIY priject wich works just flawless with an awesome app. Costs like 15 bucks a tracker.
Does this system record lap times for a DJI air unit?
Yes
Good video Bardwell, thanks
Great video, thanks for sharing.

do you have a wiring diagram for the rx, cam, and vtx, thanks alot
Yes, please download the user manual from the RaceDayQuads product page. It has full wiring instructions.
and also, since i have the flysky fs-i6 tx, how could i connect the rx using ppm, if there is a way? thank you
My FC does not support PPM or PWM input. Only serial input such as SBUS, iBus, SpekSat etc.
The TBS RaceTracker apparently can do 8 pilots at once now, would be good to see if it actually works.

Hmmm, I could probably port this to an ESP32 for Bluetooth and wireless!
You got a link to the open source lap timer?
i thought about the same thing.

github.com/voroshkov/Chorus-RF-Laptimer#rx5808-spi-patch-required
this is a more advanced timer, that work with LiveTime.

But how will you make your reference voltage for the comparator?
I believe the LapRF single puck, in fact, CAN be used with LiveTime.
You are correct, yes it can.
It can. And it can be used with good reading with up to 4 pilots at once. Just don't put the start gate at the end of a straight.
For a serious event I wouldn't use it with more than 1 pilot. You can get by with 2 pilots on the puck, but I've had lots of issues trying to use 3 pilots with the puck. It's nowhere sensitive enough with fast pilots. Personally I just built a Delta5 for slightly more than the cost of the puck and I can run 8 pilots with dedicated timers no problem.
How do you connect it? Bluetooth?
For what it's worth, Geoff tried for months to get a Delta 5 working well and never succeeded.
I'd like to purchase one of Jeff's timers. How can I get in touch with him?

LapRF works fine with live time

Or delta5, pidfligjt, wizard tracker
I would like to see it working in a slow motion and see the analysis.
I'm not sure what slow motion would reveal since there aren't any moving parts.
As many people don't know this: 0,3% of all youtube users only see auto-generated thumbnails currently. So don't think Joshua didn't do a thumbnail.
So overpriced =) while you can do similar for 50$-100$ for 8 pilots! if you know what and how to solder!

8:30 lol
Great video, but can you just stop making videos for a bit so I can catch up watching them all? :D
Save your time on the TBS one. It is a complete waste of money. Our Louisville chapter uses one and it double counts/doesn't all the time. Complete waste of money!
