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 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 custom - Arduino uno - based circuit.
- Microcontroller: Atmel ATMega328p
- Bluetooth Module: Support HC-06 & HC-05
- Motor Driver IC: Two L293D (up to 4 DC motors or up to 2 stepper motors)
- Servo motor header
- 3 input/output pins (Can be used to connect LEDs or button SWs)
- Programmable header
- Reset button
This is a small pcb that is designed to be used on an electric go-kart to display a stopwatch, motor RPMs, and cart speed as well as record this data on an SD card with a time stamp for analysis. The project is Arduino based and is ran off of 7-59 VDC or directly from a 5V source through any of the 5V or VIN pins on the data logger shield (this is not a protected input). It is designed to have w...

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 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...
