This 10 Meter Morse Code Beacon is a nice simple project, all the source code and schematics are provided. Below is a description of the board process that was used. "After I have etched the board and rinsed any excess Ammonium Persulfate off, I then use Mineral Turpentine and a rag to remove all the blue paint or blue plastic and the laser printer toner off the boards when
If you have ever thought about taking some arial photographs this site describes two versions that is sure to give you some ideas for your own. "The outputs from Air Pressure, Temperature, Wind Speed, and Battery Voltage Sensors are feed in to the inputs of a PicAxe 18X. It Processes the raw sensor inputs, and then triggers the Camera (using a Servo) and Transmits the Raw Data. A Receiver
If you like laser projects this one looks quite well done. "This is one of my experimental Dance/Trance songs from 2000. I build laser systems for fun so I have put together pictures and clips from assembly to a full working system to go with the song. I know the song gets really annoying after awhile sorry. Iv’e been getting a lot of email asking how the projector works
Baccus61 has documented some of his cool DIY Laser Etching Projects. He makes etching an image on a round bottle simple! After the jump are a few of my favorite videos he has created. "My new rotary attachment is finally ready after a couple of weeks in the making (I didn’t spend too much time building it though) It’s a Vexta 5 phase stepper motor coupled to a 50:1
This Basic Stamp Microcontroller Based Garage Parking Assistant may be overkill for the application but that is what makes it fun. 🙂 What fun would it be to hang a tennis ball from the ceiling when you can use technology to give you a traffic light that represents your optimal parking distance. "The Garage Parking Assistant makes it easy to pull in the garage by signaling you with a

"The ROV submerging technique was originally using part of a bicycle inner tube and a car windscreen washer pump. However
Re-purposing old computer parts is great since it prevents working equipment from finding their way into the landfill. This XY Plotter is a great example of re-use of old equipment. "This XY plotter was made by the group at Next Window and is the work of Paul Marson and Keith Colson, for the purposes of calibrating touch screens. It uses components that were salvaged from two old Kodak flatbed
