I also meant to ask will this new design accomodate the LR transmitter ?
K
There will only be one version. V2 will have a new transmitter chip, which will be longer range and better water penetration than the V1 LR version.
My 2 cents about trigger safety.
It was my first session. I was with the VX3 and noticed that it was once triggered from hitting the board and also I was all the time worried not to relax finger so that it won’t lay on the trigger and pull it.
So I think trigger guard is a good idea.
Or maybe additionally in order for trigger to activate - thumb to be pushing some lever.
When you have a first gerber and a bom I’d be happy to try a early jlcpcb order (and do a reflow assembly if its single side?). Will you aim for more of the brilliant pre-built kits for sale, or go opposite direction e.g publish a oshwlab type of project ready to order?
First off, @ludwig_bre thanks for a great project! And your support for this is outstanding in so many ways–super helpful to so many people.
My toggle up/down mechanism sometimes sticks. I will eventually look to modify that mechanism and replace it with two small strong force-click tactile buttons below the center of the screen for toggle up/toggle down. Waterproofing will be challenging.
How is the testing development coming along? I’m super excited to see what you come up with!
Currently working on improving the toggle as well as some first RF tests, and in parallel on a bit of a summer break. I will keep you updated as soon as I have something new to show.
Hi @ludwig_bre When you’re back from holiday: I’d like to say that I really like the BRemote, but I find that the mechanical parts are thin and not strong enough to give me confidence over time. So I’d like to try another design, more resistant like some you’ve shared above. I would also like to have a throttle lock system that is easy to activate with one hand. See you soon for a chat! Jean
How long into the future is the V2 version, im curious as thinking of skipping the Flipsky VX remote and wait for this to come instead and build that as my project probably wont be done until next season anyhow
I don’t find much time recently to continue the development…
I think it will take until the end of the year, as in December, until I have something that’s ready to be built and tested.
Sometimes R&D takes years !
No I totally understand and respect that, I will consider until then what to do if anything as I am in no rush for it.
Hi @ludwig_bre I try to hack the Bremote I love to have another display type. After some time (hard time) soldering directly on 328p chip to access sd/scl I finally succeeded and build a little poc.
I have a working alpha concept and transmission is still safe (I verified power transmission is still good with rf explorer)
For now it is simply experimental.
@ludwig_bre Just to check. Is there a special reason in term of timing or register (except autonomy that must decrease by approx 15-20% with max power) you didn’t choose ‘’’ radio.setPALevel(NRF24.PA_MAX)’’’ but *.PA_HIGH ?
No, power can be set to any level
cool thanks. I will test autonomy in this case.
It’s been a while since my last update on the development of V2. The past few months have been busy with work, moving to a new place, and taking some time for a summer break.
Current Status:
- Electronics: Mostly selected and successfully tested on the bench.
- Wireless Modules: Very pleased with their range and reliability.
- Regulatory Compliance: I’ve figured out how to stay within government limits regarding RF power and on-air time. The on-air time, in particular, is tricky and often quite limited in many countries. I’ve found solutions for the US and Europe, and most other countries should be compliant as well.
- CAD: Satisfied with the current design, though I still need to verify that all the electronics will fit within the handle.
Issues from V1 That Have Been Addressed:
- Magnet Rod Strength: Improved the strength of the magnet rods (by not having them anymore) and the trigger mounting, addressing previous issues with parts breaking.
- Assembly: Resolved issues like foam getting into the moving parts.
- RF Connector: Fixed the reliability issue caused by foam entering the RF connector and causing an E4 error.
To Do:
- Firmware: Development of the firmware and user interface, including integration with the VESC interface.
- Electronics: Create schematics, layouts, PCBs, testing
The V1.5 (“Frankenstein”) model has been tested by several users and is now on its way to the US. If you’re based in the US and would like to give it a try, feel free to reach out - I’m sure we can arrange local shipping.
Timeline:
I’ve come to the realization that I won’t have a buildable version of V2 ready this year. There are still too many open issues to address before it can be finalized.
Nevertheless, here a few images of the current idea. The current concept is to have interchangeable, user-designable hand grips that can be exchanged at any time.
First image: “raw” remote, following images with examples of sleeves for the handle. There will also be the option to mount a trigger guard.
This looks fantastic. I really appreciate all your efforts on this. The wait will be well worth it, I’m sure
@ludwig_bre did you plan to have access point on SDC/SCA on Tx please ? It will be very nice - “Hacking” V1 was relly hard time soldering to access them.
There is a quite easy place in V1 as well, on as well as below the display chip, the pins of the display driver are bigger therefore easier to solder in my opinion. Or just desolder the whole chip, one side at a time
V2 will have this on a connector probably
