Symposium Timer with Speech.
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.

Alien Bike Light Mini.
Yet an other bicycle light design which uses the same circuitry with the solar charged bike light project.
Mp3 player housing for bikes.
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.
Singing Smiley Gadget.
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.
Gamen Handheld Gaming Device.
Gamen is a gaming device with stereo sound&voice capability, 128×64 graphics LCD display, suitable for one or two player games.
It also has got temperature sensor and real time clock. The device is powered by a PIC 18f4620 microcontroller and has additional eeprom for future needs.
There are several games available for the device including snake, pong, tetris, picman and tic tac toe. New ones are under development.
Bicycle Handlebar Light.
Here is the first complete product project of endtas. It is LED headlight for bicycles. It has got two 1W leds, one with a wide angle and the other with a narrow beam angle lens.
The wide lens is a bit turned towards the ground to light up nearby ahead and the other straight ahead for greater distance lighting.
This is a microprocessor controlled inttelligent light with 9 lighting modes.
1. Double 5mm led flash
2. Double 1W leds triple flash
3. Double 1W leds continuous flash
4. Continuous power 1st grade + flash/2seconds
