That is very interesting.
Did you, by any chance, get a part number from the 8-pin chip on the blue ESC board above? The Dorman servo board? Is that the only active part on the board, or is there a small transistor too?

Re: 5V bec?
Don't most speed controllers have one built-in?
I know the Dasmikro has one, also some brushless esc.

Tiny 6mm gear motors appearing in Aliexpress
Hi, Has anyone tried these motors? https://www.aliexpress.com/wholesale?catId=0&initiative_id=AS_20190501071600&SearchText=gear+motor+6mm They are getting quite cheap and super, super tiny, maybe good for fleaweights or antweight? Would the (plastic) gearbox destroy itself instantly if we pu...

Re: A Hotel, constructed of Limas, for Ants: A Build Diary
It's easy to preach after the fact... I usually test my electronics with a multimeter (for short circuit) bench supply (for functionality) before plugging a lipo in. The Lipos give enough current to pop the magic smoke out of any faulty electronics. That said, I've never had the lipo itself catch fi...

Re: Small ESCs outside the UK
George- I will try enabling braking to see what happens. I didn't realise that braking was a useful feature, I didn't use braking on my previous robot (Betsie, which has a sort of fly-by-wire system anyway) and I've not implemented braking yet in the new speed controller (but the hardware is capable)

Re: Pre modded servo boards for escs?
Sounds more like a poor design or poor choices of parts, than a manufacturing defect. A voltage drop of 2V at the kind of current we'd see through a N20 is extremely high, did you have access to an oscilloscope? Maybe the duty cycle is less than 100% even when the stick is at the extreme position? -...

Re: Malenki-ESC open source Antweight ESC
Sounds like there is enough interest for me to knock up a batch. I'll let you know when they're ready and we can sort out the details (it will not be really soon, I need to order more parts, the boards are in the post).
There are also a few more tweaks to the firmware that I'd like to do.

Re: Malenki-ESC open source Antweight ESC
Hi, It seems the Malenki-ESC is now working a lot better. * It does bot :) - I've built part of my next bot and it's driving just fine with 2 N20s. * I solved the voltage regulation problem which caused 2 mcus to be destroyed If I make a *small* number of these boards, does anyone want to test one? ...

Re: DVD-RW motor?
It is probably a brushless motor. I'm fairly sure that the 4th wire is a centre-point wire in the Y configuration of the brushless. It could be difficult to identify the wires. I suggest something like this: * Measure the resistance between each pair of wires * The one with the lower resistance to t...
