Do you remember those first 8 bit computers and video game consoles? Do you remember how beautiful music they were able to play? This unusual device is a combination of modern technology and charm of 90’s. A seemingly simple plug, hiding a very small attiny10 microcontroller and two watch batteries inside – plays 2 minutes long Chiptune track, after plugged into the amplifier input.
The “not-ordinary bulb”, as title say, typical glass and metal bulb with electronic inside. Powered from miniature AC-DC converter – i have used that one from 230-5V USB chargers – it has enough power (about 500mA) for few RGB leds. Next is Attiny13 (SOIC8 package) based RGB driver, it not only can change colors, but has 3 modes and an automatic color and mode saving to eeprom memory – so after power up you always will see last seen mode and color.
Interactive mug coaster, thanks to analog temperature sensor LM35 and uC builded-in analog-digital converter, device can read temperature from standing on it glass. Device calculates temperature and smoothly light-up our drink with slowly changed RGB colours. When temperature is under 20*C then displayed colors are cold, and when temperature is above 28*C then colors are hot. When nothing stands on device (temperatures from 20*C to 28*C) then it automatically swich off. Fusebits are: 4,8Hz internal clock, not divided by 8. Supply voltage is stabilized by 1117 type stabilizer to 3.6V. The red LED requires lower voltage, and current on that…
3W RGB mood lamp, a “mylonit” lamp from ikea. Powered from TNY245 based AC-DC converter. Next is Attiny13 based RGB driver, it not only can change colors, but has 3 modes and an automatic color and mode saving to eeprom memory – so after power up you always will see last seen mode and color.
