Chris Gregg made a an interesting Computer Printer made from a Typewriter, the typewriter is an old mechanical style and there is a bunch of electronics and solenoids attached to make the magic happen. The solenoids press the appropriate keys to type on the keyboard. One issue is that a microcontroller with enough outputs to drive this number of solenoids is not that common in the DIY space. Chris
If you like to see some real backyard hacking have a look at this video by kurtscottage. He is spinning an old car alternator with a gas motor and with a bit of rewiring and connecting through some home made transformers he is able to generate 120 VAC. Now the frequency is not always 60 HZ so I am not sure I would connect my laptop charger the the

 We have seen lots of interesting projects made for little money using scrap electronics like Microwave Ovens, for this project you will need a piece from another throw away item, a CRT TV. This CRT TV Flyback Transformer High Voltage Power Supply by Robert Gawron is cheap and easy to build since the main part can be found for free in a discarded old TV. It sure makes
If you shop is in need of a new toy a Pocket NC 5 Axis CNC Mill might be just the thing! I have had so much fun with the Laser machine and the CNC machine that I have but none of the equipment I have is well equipped to work with metal. Also a basic CNC machine can only move in the X and Y axis and drop the cutting
Julian Ilett has a look at a AD9833 Waveform Generator.  It looks like a nice device. Connect a microcontroller to it and use SPI to interface to it. You can set it up for square wave, sign wave or triangle wave all through SPI.  The AD9833 looks like it could be very useful whenever you need to easily generate specific frequencies. The module that Julian is using was under $7 with free
