Re: Help/Build diary for/of my first antweight.

Looks like it will probably work. Check that the servo can run off the maximum battery voltage (e.g. 2S lipo = 8.4v) otherwise you'll blow it. I assume it's a "high voltage" servo, then it will be fine. I see your brown wire - the GND / negative power to the servo - which you've shown going through ...

Re: Work in Progress preview: An(t) Object to be Destroyed

Maybe a thin piece of Ti over the lipo, to make things a bit trickier for Shakey if you get drawn against "It's only a drill" ... ?

Re: Work in Progress preview: An(t) Object to be Destroyed

Nice chamfer around the switch cut-out, makes it harder to get accidentally swiched off. Nice detail.

Re: Work in Progress preview: An(t) Object to be Destroyed

Good to see that you're still building! I have noticed lots of fancy 3d filaments kicking around, but now I've just picked up some bargain-bin Nylon and it seems pretty good. At least, we'll try with the plain Nylon (Nylon 645) and see if that holds up better than the PLA which I used before (and tw...

Re: ESC with built-in receiver - interesting?

That will only happen if: a) The parts are available b) I have a DSM transmitter / receiver to test with Right now I'm still trying to get the previous one working. The radio compatibiility between different chips is an unknown, possibly they will only talk to the same company's devices. The origina...

Re: The smart ant's and flea's

Congratulations. Good job!

Did you write any spec / doc? Is that the board with the chunky SMPS for 5v?

If you have trouble taking photos, try putting it on a flatbed scanner, I did that at some point (note: scanners have a very short depth of field)

Re: ESC with built-in receiver - interesting?

Yes, I abandoned that prototype and assembled another one. This now seems to mostly* work. I also took an earlier prototype and put it into a Antweight-sized test robot ("Bernard") and it drives pretty well. Additionally, the receiver in Bernard has working telemetry which gives battery voltage - I ...

Re: ESC with built-in receiver - interesting?

Kyro, you are exactly right, pin 7&8 are connected on all of the motor driver chips. However, this isn't a design fault, it's actually supposed to be like that (they are the vcc and enable pin). The traces join and some solder tends to wick into that place. It's not a mistake. There were multiple fa...
