Not mods but electrics electronics info wanted.

Got the tattoo route sorted now I think in my head.


Specification：
Brand new, Unused, High quality
Material: Plastic, metal
High efficiency, high torque, low heat generating
Control the speed of a DC motor with this controller
With reverse polarity protection, high current protection
Input: 10V-30V
Output: Max 120W（When more than 24V）
PWM range: 5%-95%
Frequency: 500Hz
Current: Max 4A (Recommend you to use in 3A)
With potentiometer
With reversible switch
All tested before shipment

With this second unit.
I'd need a transformer (simply like phone charger) that would output 10-30v to get full use of the unit above.
I'd also need a motor that could use upto 30v, again to get full benefit.
And the motor should be rated at no more than 3a.
If I did use a 12v motor, a 12v transformer would be sufficient.

reads ok to me,, again an unqualified amature..

i would start with sourcing a motor, and then fit the psu and control circuitry to fit tho..

fwiw the ebay links are just examples, the first spat out after a quick search, not specific recommendations

[bigd]

That's brill mate. I'm waiting for a motor off a friend so when I get that I'll source the rest. I'll have a word with my tattooist as well see if he give a few tips as well.
Cheers.

good stuff.. when built how about making an instrctible www.instructables.com/ to share the benefit, and post a link here too

[bigd]

Don't do the instructables thing. But I'll put as much info up here as I can. I'm always open to answer if I can.

Getting things together now. I've got my hands on these. It's a 12v motor so if plugged into the dedicated 12v output should it work ok? I understand the the voltage side it's the amps that boggle me.

[nanotm]

you would of been better off getting a £10 drill from a hardware store and pulling it apart for the bits ... but having said that the amps limit should be printed on the faceplate on the motor drive or on the manufacturers website

Just got hold of a small router I could use, I have a rotozip as well I could use. Just wanted it to look the part as it's more a hobby toy than a tool. A friend has suggested a singer sewing machine motor with the foot switch could be a good alternative. At least I have a few options now. And now winter is here and I work outside mainly, it's on hold while I start sourcing the parts needed.
Cheers.

Nice looking motor.. and a tidy versatile psu..

my laymans understanding is if you have a device that requires X amps to run under load (work) as long as the power supply can provide More than X amps your fine.. if the device is rated in watts you can google an online converter, just ensure you select DC voltage.

with that psu and a 12 or 5v motor i would use the dedicated connectors, if the motor is a different voltage, then use the banana plug outlets and adjust the voltage with the voltage knob.

the current dial set higher than the amp rating of the motor.

if you require a variable speed for the motor, use the banana plug outlets and use the voltage knob to control the speed.
