Question
Homemade ESC Build Source

Does anyone know where there is a detailed construction process for a home made brushed motor analog ESC?

There are a few designs here:

Why analog?

Analog because I cannot find digital chips around here.

Here is another one. I actually have a few PCBs for this one, probably some of the other parts as well.

I made a few of these back then. Nice little ESCs.

On closer inspection, the Cano controller I linked to above is not the same as the one I have the PCB for. . They show the parts layout for the one I have in the link though.

Thanks for the link. It looks like it gives a pretty good overview and parts list etc.

Digikey, Mouser, or Farnell ships anywhere on the planet. Are you not on Earth?

Can you telephone an order? Those companies take charge cards over the phone, too.

Use that output stage with a PIC instead of the analog stuff and you would have a fairly simple circuit. (Offset by the complication of programming )

As I rely on my parents to order stuff and they are paranoid about phone and internet ordering, no I can;t order over the phone.

Thanks for the pics and schema.

3 ICs and about a dozen resistors would be replaced by a single 8pin microcontoller. But without a program the ESC would not do anything.

In order to program the micro you would need a programmer. More stuff to either make or buy.
And you would need to develop the code. So the "simpler" circuit could end up taking longer to get working.

aha i see now. That's all the more reason to stick with an analog controller.
