Richard Harris made a low cost micro CNC machine that uses old floppy drives for the movement. The video above is 10 in the series, if you would like to build you own you will need to start from video 1 which is here. It won’t do anything big, but what do you want for a machine built from parts that would normally be tossed out?
Ian Johnston purchased a used Pioneer amplifier that was slightly defective. The amplifier would not function when the tone controls are switched in (this amp has a bypass switch which allows these controls to be bypassed). Turns out that the amplifier was fine, the issue was missing RCA Jumper Links , you can see what these jumpers normally look like in the picture below. This amplifier doesn’t have a
Instead of using keys and codes for security this device that Ankur Thakkar, Darshan Shah and Saisrinivasan Mohankumar built as part of their ece4760 Final Project uses gestures to grant access. The system uses IR sensors to determine the movement of a persons hand within the detection area, after you train the unlock pattern you can simply repeat the pattern to activate the device. I think a small miniature
Z LeHericy shows us how he used a WickedLasers Spyder Arctic 3 laser to do some laser etching. This hand held laser is very powerful at 2 watts but it isn’t much compared to real laser etching machines such as the one that was used to make the etched orange, this one for example is 60 watts. The result of the leather etching is quite nice but I am
