29. Multipurpose digital microscope

This particular DIY tool is essential to make, since not only it's a beefed-up version of the helping hands, it can do crude photography, light up the area, and so on. The list goes on and on, but its main purpose is to make SMD soldering easier, since it has alligator hands to hold the board in place, but it also has an adjustable camera for a magnifying glass replacement.

It uses helping hands as the main part, as well as a webcam, a junction box, a USB socket, a 12-volt led w/ AC module, and a 5-volt regulator. the wiring is simple, get the AC to DC 12-volt module, wire it up to the switch, and the 12 volts led. Then, 2 more wires were soldered in place of the same connection of the module for the regulator. This is when you can solder in the USB socket, assemble everything together, and you are done!

It only uses 120 volts of VAC for the system, yet the circuit module converts the AC voltage into DC voltage just so it will prevent the lens from blowing up. It's possible to power it directly from the 12-volt source, but seeing how AC is more accessible at home, it's preferred.

As I said, it's a simple tool to make, but it gets the job done. Not to mention, you can upgrade the unit, such as replacing the webcam with a better one!
