This is a bicycle computer product with 16×2 LCD screen, real time clock, temperature sensor, light sensor, total & trip distance measurement, even a knight rider led display that changes its swing speed according to the bike’s speed. A very fun project.
A product powered by pic 12F675 microcontroller. The circuit drives 6-8 leds separated into two groups which can be red and blue, imitating a police type rear-front flasher.

This is a timing device which I’ve made for a symposium in our university.
You adjust the time in the splash screen then press and hold SAY (Count) and it counts up to the adjusted time.
The timer will announce the last minutes of the time by led effects and speech.

Yet an other bicycle light design which uses the same circuitry with the solar charged bike light project.
The mount is for chinese made rectangular mp3 players which are abundant on the market. They are cheap and run good too.
four parts. The mount holds the player on the handlebar while reflecting the sound of the side-placed speakers to the front.
suitable for bicycles as well as motorbikes.
Here is an other recent project, full schematic etc of a gadget that displays a smiley face on a 5×7 matrix led screen which sings along with the music around.
