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...

PiHome Wireless Multi Zone Controller Relay with nRF24L01
PiHome Jun 29,2018
### DESCRIPTIONWireless Arduino Multi Zone Controller Relay with nRF24L01: If your house have Multi Zone Heating then you can control each zone heating independently with raspberry pi and this will save you lot on your heating cost considering that you don't have to heat all the house all the time. For this purpose you need to build wireless relay switch as Multi Zone Controller so we can open and close zone valve to circulate water in each zone as needed. PiHome comes with ABSOLUTELY NO WAR...

Talking Smart Glass For Blind
S Jun 15,2018
Talking Smart Glass For BlindThere are multiple smart accessories such as smart glasses, smart watches etc available in the market. But all of them are built for us. There is a significant lack of technology to aid the physically challenged. I wanted to build something that is useful for the visually challenged people. So i designed low cost smart glass that can be used to help the visually impaired.This project uses few Ultrasonic distance sensors, an arduino pro mini, mp3 Player module and so...

Arduino based portable soldering iron board
ELECTRONOOBS Jun 12,2018
ELECTRONOOBS is on fire. Here we have the PCB he just ordered for his new project. After reviewing the TS100 portable soldering iron, he was amazed of the internal structure simplicity. So, he started designing his own board for a new project, a portable soldering iron. The board looks complicated but it’s quite simple. In the middle, the microcontroller and 4 pins for an OLED screen. That screen has i2c communication so SDA and SCL pins are needed. On the left side, a place for two push buttons...
