Affordable Rock Tumbler B&D Drill Motor Version

thingiverse

Bad news! Don't use the DROK voltage regulator because it won't supply enough volts for the needed amps to power the drill while under a load, such as when a can is loaded with rocks. I need a different voltage regulator that will put out higher volts so the drill can draw the proper amps which will increase torque. If not, I'll have to figure out a different gear system. I'll try to find another better-suited voltage regulator and report back once I get some time. 2nd note: The DROK works perfectly when using a very light weight container, like a large peanut butter can. It just has to be loaded with the right amount of rocks so it doesn't overwork. Also, make sure to line up the rollers in the proper place or it won't work right. I had a new drill without a battery sitting around and I didn't want to buy a separate motor when I could repurpose the one from the drill. It was a B&D drill and all I did was change how the motor was attached to the left frame. The rest of the parts can be found under "Affordable Rock Tumbler by J_T_3_D". I'm going to attach a variable power source so I can vary the speed based on the weight inside the drum, hopefully extending its life. I'll use an old power supply that's free and connect it to the DROK Adjustable Voltage Regulator Stabilizer 5V-23 I bought from eBay for around $12. It cost me less than $25 total since I had many of the parts lying around plus some plastic. Thanks to J_T_3_D for creating such a great product! I followed their instructions to the letter and it all worked out perfectly. UPDATE: I finally got my DROK voltage regulator, and with some experimentation I managed to find a toggle switch from an old radio that fits perfectly. I also salvaged a power supply from an old printer that stopped working and created the power supply cover I needed using an STL file. If you don't have all the exact parts I used, you'll need to remix it but this should give you a basic outline of where everything goes.
