16-Channel Servo Controller
I needed a servo controller that was capable of controlling multiple motors at the same time. Using a commercial controller was not an option because I needed this controller for my final project in How To Make Almost Anything and Neil Gershenfeld wanted us to fabricate all parts of our projects. I designed a controller [...] -
Sonar Sensor
I made a sonar sensor to sense distance. I used two ultrasonic transducers, an op-amp and a microcontroller for the job. Basically, the microcontroller creates a pulse train of about 20 pulses at 40kHz, which is the frequency that the transducers are optimized for. This pulse train is sent to the transmitting transducer. Once the [...] -
LED Message Badge
I made a custom message LED badge made in response to the Star Simpson controversy. Star was a student in our group and got a very unfair treatment by the authorities, the media and MIT when she accidentally wore an electronic badge in the Logan airport. I made an array of 36 orange LEDs, found [...] -
Remote Control Echoer
When I moved to the states I quickly got annoyed very annoyed about how advertisements on TV are set to a much louder volume than the regular programme. I quickly became a master of the art of the “remote quickdraw” and was constantly lowering or increasing the volume on my TV. I then decided to [...] -
Differential Op-Amp
This was a project that I had in another one of my favorite courses, Electronics II. We were supposed to make a differential amplifier from discrete components only. It was supposed to meet strict requirements such as: Ri = 100k +/- 10% Ro = 100 +/- 10% Operational on 9V DC OC output 6 Vpp [...] -
Analog to Digital Converter
This was a fun project I did for a class in undergrad. We basically had to design a 4-bit analog to digital converter using only resistors and NAND gates. Obviously the best design is the one that uses the fewest components and that was the challenge. The product makes for a nice Christmas decoration when [...]
