Picture of CD-ROM Agitator
These are step by step instructions on how to hack an old CD-ROM drive and turn it into a agitator for PCBs, biohacking projects and anything else you might need to shake continuously. All you need is a CD-ROM drive, breadboard, H-Bridge, a 10Kohm resistors Arduino, plastic container and power source for the Arduino (a toggle switch is optional).

Step 1: Get a old CD-ROM drive

wich H-Bridge are you using? SN754410, L293 or another one?

Hey there,
Ah forgot to include the type, sorry about that. I used the L293NE H-Bridge but you can also use the SN754410. I used this tutorial as a reference when putting it together. Hope thats helpful. Cheers.

Bubbling air through the bath is so much more effective. Doing that not only agitates but oxygenates the fluid too. I made mine with one of those 12 volt tire inflation compressors. I stuck a spray nozzle off a spent spray can on it and it is perfect.
