The EasyEDA "Tesseract" DIY Guitar Practice Amplifier is an LM386 based low power amplifier designed to deliver up to about 500mW into an
8 Ohm speaker when run from a 9V battery.
**Tesseract can be heard on YouTube here:**
The design given here - which includes a complete PCB design and Bill of Materials - is highly flexible and allows the several options...
This afforable Geiger Counter that works as standalone device and also can connect to other external devices (like RaspberryPi/Arduino or other GPIO devices) to send the "clicks" thru GPIO interface.
The Arduino code for the Geiger counter is available here:
- Pin D2 --> Arduino interruption
- Pin D7 --> Buzzer
- Pin D8 -->...
# **DIY JBC 245 Controller (not tested yet)** #
Wich can be powered with a standart 19V DC laptop charger.
The project based on the Atmel328 μc, and i try makes simple as i can. The first problem driving a jbc tip is the thermocouple and the heater have a common pin and its not the GND. On some forum i found the easyest way to do is just siple pass the heater current on the thermocupple but thats...

THIS WORKS AS A REGULAR ARDUINO. ALL U NEED TO DO IS SOLDER THE COMPONENTS AND UPLOAD THE CODE USING AN (FT232RL USB TO TTL CONVERTER) MODULE. IF U DONT HAVE IT THEN SEE COPY THIS LINK AND SEE IN GOOGLE,
This is a simple arduino sheild that can run on it's own as an arduino uno once it's powered up using the power input. to upload a code, simply remove the **ATMEGA328p** from your reguar arduino board and place this sheild on top of it. Then plug ur arduino board and upload a code.If you want to burn the bootloader of ur ATMEGA328p chip, then udon't have to remove ur ATEGA38p chip from ur regular...
The Arduino platform has become quite popular with people just starting out with electronics. It is an open-source hardware design, based on microcontroller board designs and provide sets of digital and analog I/O pins that can be interfaced to various expansion boards ("shields") and other circuits. The boards feature serial communications interfaces, including USB on some models, for loading pro...
I always wantedo create a color organ, and recently I started learning about electronics.
I designed this circuit, but never tested it yet (waiting for parts to arrive).
If you have advise, please feel free to contact me here: https://goo.gl/xBLJye
It is possibe that I designed something wrong, so if you find any mistake, please contact with me. Thanks for your help.
