ISP Shield programmer for ATmega / ATtiny
PUEYO MUÑOZ Jul 26,2018
I have used these PCBs in an ISP programmer Shield for ‘Arduino UNO’. This programmer is compatible with the microcontrollers: ATmega 48/88/168 / 328P with 28 pins, and ATtiny 25/45/85 with 8 pins. ### TECHNICAL DETAILS / COMPONENTSISP programmer for ATmega / ATtinyBy making a small modification on the ATmega ISP programmer, we can make it compatible with ATtiny 8-pin micro-controllers. If we observe the distribution of the pins of the ATtiny microcontrollers, we can verify that if we inser...

Sinclair Scientific Calculator Emulator (v6-11-rc8)
Arduino?Enigma Jul 08,2018
Here is the latest version of the Sinclair Scientific Calculator emulator running on a custom PCB which accurately replicates the size and the circuitry of the original calculator. This is powered by an Arduino Nano.PCB v6 is the same size as a real Sinclair Scientific Calculator, the keyboard and display circuit is accurate as well.A matrix keyboard and 9 digit LED display are connected to an Arduino Nano. The Nano runs a port of Ken Shirriff JavaScript 0805 TI CPU Emulator. The emulator is exe...

Arduino Nano Q.P.
Mauer Jul 04,2018
### DESCRIPTIONDo you also have the occasional problem, that you want to create something with an Arduino, but the workshop is a mess, you find neither a suitable display nor the right button, and finally, if you have everything together, you lost the desire, to realize the idea. That's why I have developed the Arduino Nano Quick Project. It's a ready to use box, which should be able to realize 85% of all the small ideas somebody can have. You have buttons, inputs, outputs, a displa...

PiHome Temperature Sensors_PCB
PiHome Jun 29,2018
DESCRIPTION18650 battery powered Arduino DS18B20 temperature sensor would lost many years without to re-charge or replace the battery, for temperature sensors its best to use 3.3v Arduino Pro Mini with lower clock speed to conserve battery. To optimize further i have removed power LED and status led connected to Arduino mini pin 13, then feed power to Arduino mini through raw pin with 18650 battery. i have these sensors running over 16 months now and battery is still 96%. It is very low power ar...
