building my own esc? parts?
 
I would like to try to build my own speed control, but have no idea where I could get any of the parts. does anyone know where I could get everything and exactly what all i need? thanks

unless you are a EE with LOTS of expierence dont bother....:lol:, you than have to have good software which would take being a SW guru....

Just go to Radioshack and get a PC heatsink and some wire. Shoe Goo them together and you have an ESC comparable to a 15 minute old MMM :) Sorry, I 'm a Jerk. I still love Castle though.

haha swing and a miss on my part i guess... oh well it was a cool thought.

pullinteef - is that an rx8 in your icon? that yours?

If you wanted to try and make a sensored ESC that would be much easier. At least from a SW standpoint.

At one time there were kits available to build speed controls for brushed motors. I built several. Most used multiple mosfets in parallel (TO-220 case) , op amps like a NE544 and IIRC ran at a 60 hz frame rate. The kits ran 30-50 $ and worked quite well. This was 15 to 20 years ago. I doubt anyone now would be able to market a kit for a brushless speed control at a decent price-much to complex. Don

yeh. oh well. again it was a cool idea...

Yeah, It's my '04. It's going to be 5 years old in August. Still a super fun car.

Revracer 06.17.2008 11:03 AM

aye. i got a '01 s2000. little cars with lots of speed.

Way back, maybe 30 years ago, when Novak first started---and even earlier when Bob worked for Micro Avionics and then Orbit, there were companies that kitted up parts for electronics. I think Ace and Royal Electronics sold servo kits and probably receiver kits.

I don't remember anyone kitting up speed controls. Even the earliest Mosfet escs--for cars-- in the early 80's were pretty challenging. I do remember when a Novak employee---Eloy Marez, who wrote articles for one of the airplane mags, did a piece on building a simple esc. But, I believe, it was for an air model.

Yup- I built several Royal and Ace rx kits and a # of Ace servos( loved those Bantum Midgets). The speed control I used in my RC-10T was put out by Howard Cano. I think he also put out a line of kits under the name of Eldenken Electronics-both were in Arvada Co. The speed control I used in my RC-10T used a NE544 and 3 IRFZ-42 mosfets, one for brake and two in parallel for throttle. I still have the instruction set and schematic. I also built a peak charger from Cano- I still have it and the last thing I knew it still worked. (nicad only) Building those kits was fun, economical and challenging. Don

Here's a little something if you want to build one: http://tehdevs.net/2007/11/03/diy-el...ed-controller/

Of course, if you want things like reverse (need an H bridge for that, or a relay to reverse motor leads), and programming options, it gets more complex. :smile:

Seems easier to simply buy one off eBay, unless you're just looking for something to do.

Revracer 06.17.2008 12:36 PM

I'm really just looking for something to do. Seems like it be cool to build and run your own esc... might end up buying a cheapo off ebay to see if itll somewhat handle my revo or another larger truck.

lutach 06.17.2008 12:56 PM

Since this is in the brushless thread, my guess is you want to build a brushless ESC? If you want to get deep down into this, make sure you have some quality reading time. This is by far the best DIY BLDC thread out there: http://www.rcgroups.com/forums/showthread.php?t=200567.
