If you have a laser cutter focusing the laser on your work can be tedious if your system doesn’t have a way to adjust the distance from your work to the laser automatically. Now as much of a pain this is for a flat item it is impossible to generally do with an item that varies in height. Martin Raynsford has solved this issue by bolting a Wiimote to
This project makes a Vintage MP3 Boombox with a few simple steps. By using an inexpensive Bluetooth MP3 player this old Candle Model JTR1296 Boombox can now be used to crank out some MP3 tunes direct from your smart phone. The boombox is a 12 volt DC player which can get power from D cell batteries, a 12 volt DC input jack or wall power (which is rectified using
