ESP8266 Desktop Clock (WiFi Synchronised!)
The ESP8266 is a awesome chip; with integrated WiFi, 80MHz clock speed, total 160kb RAM, 512kb of flash memory, and a ton of other features, it makes a regular Arduino look like a joke. The project shown in this Instructable is based solely on the ESP8266-01 module, unlike several other projects on the web where it is used in tandem with another microcontroller. This makes it great demonstration of the capabilities of the ESP chip.The desktop clock I made is pretty much bare-bones, but equipp...
ATtiny Watch Core
This instructable show how to use an ATtiny85 to create a tiny watch core that can run over 1 year before recharge or replace battery.The instruction to make the watch case may be in next instructable.I have made a few Arduino watch before, but I found the watch using ATmega boards or ATmega chips are a little bit too big to wear. So I would like to make it with a smaller chips.I have choose ATtiny85 just because I can easy to get one.The challenges for using ATtiny85 are: It only have 8K fl...
ATtiny85 Sound Level Meter
ATtiny85 Sound Level Meter, displays the input from an electret microphone on a bargraph display. It's sensitive enough to respond to speech, and shows just how much functionality you can get out of the tiny 8-pin ATtiny85 processor. The ATtiny85 not only drives the 10-bar LED display directly, but it also receives the direct input from an electret microphone, amplifies and digitises it, and converts it to a logarithmic value before displaying it. The project could be used as a display for you
