Higher amp power supply?

Post by lasershark1 » Thu Apr 26, 2012 4:36 am

Instead of an AC dremel I'm thinking to use my Ryobi One+ SpeedSaw rotary cutter. 18v DC brushed motor, 26k rpm, and can take 1/4" bits. Much more powerful than a dremel tool. But someone else posted that it draws 5.6 amps.

Anyone know of a better power supply that can push those amps? I dont want to have to get two... would prefer a single supply.

I've got 2 power supplies, one eBay 12V that I'm using for my ORDbot, and a 24V from Digikey. The build quality is similar, so I would just say buy a 24V power supply from eBay and see how it goes. I found this one which might work for you: http://www.ebay.com/itm/18V-10A-DC-Univ ... 3f0794d7b1

18v 10amp would certainly do it, and do it perfectly. More than enough volts and amps for the X and Y axis, enough amps for the spindle, and the Z axis is negligible...

And if somehow its not good enough, it'll power my halloween props quite nicely :)

Just wish it had a 5v out for the arduino.

Any reason you don't want to power the arduino off the USB port?

Another option: http://www.ebay.com/itm/DC-DC-converter ... 3cc5701c49

Gives you 5V from 8-23V. Don't know if I'd trust the 3A rating but should be fine for the arduino. Only $2 free shipping.

I just wired up a MW 24V DC14.6A 350W Regulated Switching Power Supply. This is a very nice supply.

I found them on Ebay for less than $30 (even though I paid more than that for mine through a more established dealer) Ahem. Maybe next time.

I was thinking about getting one of these also. Any problems with it?
