Adam Jackman and Pouria Pezeshkian designed a cool Digitally Controlled Electric Guitar for their ECE 4760 Final Project. My daughter is learning guitar and I can see that the electric guitar can have its sound modified in interesting ways just by twiddling the knobs on the guitar. Only issue is it’s hard to revert back and forth between different sounds without lots of trial and error. Adam and Pouria have
Remember the PIC 16F1937 Capacitance Touch Switch Keypad Project that we featured last week? Giorgos from PCB Heaven has been hard at work integrating the keypad into a larger project which is a DIY Keypad Door Entry System. A bunch of videos can be seen here and the build log with lots of pictures can be found here. If you want to build your own Giorgos has made the schematics
Have a look at the NANO.r00t-Ed site for some interesting projects including this LM34 Temperature Sensor Weather Station Project. It uses a LM34 temperature sensor which is similar to the LM35 that I used in the PWM fan controller project except it outputs voltages that scale with Fahrenheit instead of Celsius. There is a microcontroller that reads in the voltage and determines the temperature which is sent to the weather
Making your own PCBs boards is a time consuming task. If I need to make 1 or 2 simple boards I don’t mind spending some time and building a few but if you will ever need more than that you better look at getting them made by a professional PCB manufacturer. This means that drawing a picture of your copper layer in a graphics program and printing it on a
Owen from Hackniac has just finished his latest hack. It is a game called TinyCopter that is built into the very small code space of a Attiny13 and uses a Nokia3310 LCD for the game screen. This tiny game reminds me of a game I used to play on the Apple II where a green screen helicopter would fly around and you just pressed the space bar to make the
The prize this week is a cable tester which will make sure your home made cables are working correctly. This contest will run for one week (June 25 – July 1, 2011).

Drilling holes in PCBs is one of the most boring tasks I have ever done. Positioning the board isn’t the hard part, pulling the drill press lever up and down at a rate that won’t break the fragile tiny drill bit it the thing to watch. This PCB Hole Driller project will solve this issue by allowing you to simply position the board and hit a foot switch. The system
