A rework station is pretty easy to use, I would order blank 2-sided PCBs and solder my own SMDs if that’s what was necessary for a “mini” version.
This is still my favorite. The only thing I don’t like about it is the rubber cover comes off.
We’re going wireless!!
How does it look inside? I am super excited about this project! Keep it up!
My dude your hand looks animated AF. Are you sure this isn’t in VR?
It’s a little bit messy at the moment because I was impatient and couldn’t wait for the BMS with integrated regulator, so I ordered a simpler one from Amazon and crammed an extra regulator in there
Next shell is gonna be PETG and printed at 0.12mm later height instead of 0.3 for extra smoothness ^^
I’m pretty sure I am still real, but the simulation has been a little bit wonky lately…
Silly question,
Why are you inluding a BMS? Unless your power source is greater than 1s, wouldn’t the BMS be unnecessary?
You’ll still need overcharge/overdischarge/voltage protection. It’s like the protection circuits you can find in some Li-Ion cells.
@Baxter this. Even a single Li-ion/LiPo cell should be charged through an IC that ensure you’re not pushing the chemistry to dangerous levels.
I’d make the remote a bit thicker and use one of these protected cells. Love me a remote that only needs charging once a month.
put an entire 18650 in there and I am a customer.
This. If I can just carry an 18650 (or better yet, an 18350 or 21700) in there, then I’ll preorder 3 in a heartbeat. I’ve already been planning to use an 18350 with the internals of the mini remote in a custom enclosure. Standard replaceable battery would be such a boon to so many people.
It’s definitely an idea, but at the moment I’m struggling with the size of the remote and definitely a big ass 18650 is not gonna help.
However, I’ve made some good progress on PCBs v1.0 and managed to shave off a few mm here and there, so I’ll definitely consider a shell that can house one.
On the software side, I have implemented task scheduling to try and squeeze as much performance as possible from the 8MHz Arduino. There’s also battery level monitoring, LED and motor control and a primitive “display mode” switching to show different info using the LEDs (board/remote battery, RSSI)
Have you seen how small and cute an 18350 is?
Maybe 14500 lithium cells? Form factor of AA battery.
Small update:
Software has progressed nicely and I now have a working prototype that refreshes throttle at approx. 50Hz (tougher than it seems on an 8MHz Arduino) and receives telemetry from the receiver at 2Hz (more than enough for board battery since it should be an average anyways)
I live on a 4th floor and made a friend hold my rear wheels up in the air while I took the remote down to the ground level through a metal elevator. I was still commanding the board when I got out of the metal cage
Next up: the near-to-final thumbwheel case and a proper ride!
- Charge
- On sequence (wait for LED animation and vibration to stop)
- Mode 1 (board voltage with customizable curve)
- Mode 2 (remote voltage with customizable curve)
- Long press for off
Changing modes makes the remote vibrate (twice if you go to mode 2, once if you get back to 1)
18650 version pwease. C:
Also: is it possible for a longpress to activate a certain top speed? For us people who live in over-regulated areas.
