The new batch of Cornell University ECE 4760 Final Project are in! There are tons of cool projects as usual, everything from Human Tetris to this MIDI Glove Controller project by Anson Dorsey, Eric Gunther and Jonathon Smythe. The project is based around an Atmel Mega644 microcontroller which has lots of processing capability and all of the projects are developed in WINAVR/GCC. Since the system is outputting MIDI you are
If you need to do some temperature monitoring over a long period of time this is the device for you. It can store 32 thousand measurements and has a current draw of only 50uA. The top picture is version 1 and below is a shot of the surface mount version 2. Via: Electronics Lab “The PIC software is written in assembler and based on earlier projects using I2C interfaces. The
So you think your meter is tough do you? Dave Jones of the EEVblog took a few cheap and a few high quality meters and subjected them to some high energy discharges. If may have seen a component let out its magic smoke but it is something else to see a meter literally blow apart. This destruction is all thanks to a machine that Doug Ford built.
Laser harps seem to be catching on. This one is a work in progress and believe it or not there is no microcontroller or computer controlling the system. For more information have a look at the project page (translated version). “This is my first video showing the sensor-circuit working, that contains 4 opamps (LM358) and only has a +5V supply (no negative supply). You can understand it’s a challenge to
Our friend Csaba Bleuer sent in this crazy project he completed. It is a Rotating LED Globe which is being driven by a ATMega Microcontroller. The globe image was created using a program called BmpToAscii, with this program an image can be converted into Ascii. In this case the Ascii is used to display the globe! We have seen some other spinning LED globes in the past but this one
DIY medical equipment is not a big hobby area but this DIY Pulse Oximeter is one cool device. I have no idea what a commercial Pulse Oximeter but like anything medical the real stuff that is used in hospitals usually costs big bucks. In this case your finger is slipped between two pieces of medical grade oak to take the reading. The project is based around the powerful 68HC908AB32 microcontroller.
We often keep important data or personal information on devices that we feel is secure. Well think again. Even though these phones that Will O’Brien picked up had their personal messages locked by PIN simple plugging in a serial cable allowed the messages to be pulled right out. “Hooking up the serial port is just a matter of connecting a 3/32″ audio connector up to a TTL USB serial cable.
