IGBT Bridge for pi tesla coils V2

Generic breakout panel for Speeduino V0.4 EMS. Mounted in a Hammond 1455 enclosure. Revision 1.

A simple christmas ornament with an attiny85 and an RGB LED.

This PCB will live inside of a simple christmas ornament and play fun light patterns on the RGB LED.

GAME CONSOLE ARDUINO Avr Arduino Game Console,if you want the schematic to look over just ask at [email protected] ,a 3.2v battery will be soldered to the pads in the middle where the circle is negative left and positive on the right pad. So solder the battery there,and the pinouts on the left are for the sd card breakout board,they are the ones off ebay called catalex,they are blue,left to right is gnd vcc miso mosi sck cs.download all firmware at gamebuino.com. Use a 2 gig and under sd card only ,there are loads of games on the site too,you need the bootloader burned to the 328p, and also the loader file and settings file need to be downloader and copyed to the sd card with the games hex files all the instructions are on site.thanks

BLDC Controller Board V1-0

This is a open source Brushless DC Motor Controller board, first prototype.

Max: 20V (4 Lipoly in Series), 25A (speculative, depending on heat dissipation).

Controlled by PIC32 MCU, commutation running in sensorless mode. Controlled remotely via SPI or UART interface.

3rd board for NEDONAND project

It’s stackable 4-bit part of NEDONAND program counter with parallel load that uses 2 board NEDONAND-2 to count from 0000 to 1111 binary. Pins description (2 rows - male for inputs and female for outputs):

1.1) IN (OUT) - count enable
1.2) ACT0 - external writing signal "0"
1.3) ACT1 - external writing signal "1"
1.4) /RESET - master reset
1.5) CLK - clock signal
1.6) NC - not connected
1.7) VCC - power +5V
1.8) GND - ground

2.1) D0 - bit 0 for writing
2.2) D1 - bit 1 for writing
2.3) D2 - bit 2 for writing
2.4) D3 - bit 3 for writing
2.5) D4 - used in next stacked boards
2.6) D5 - used in next stacked boards
2.7) D6 - used in next stacked boards
2.8) D7 - used in next stacked boards
2.9) D8 - used in next stacked boards
2.10) D9 - used in next stacked boards
2.11) D10 - used in next stacked boards
2.12) D11 - used in next stacked boards (in case of 2K memory it's "0")

4-bit address output header on the right:

3.1) A0
3.2) A1
3.3) A2
3.4) A3

This is the RS16 motherboard that has edge card connections for all external boards.

This board is the Thruster bus breakout board for the RS16 submarine.

This board is the RS16 thruster control board.

This is the actuation board for the RS16 submarine.

This board is the LED controller for the RS16 submarine.

This is an I2C bus board that turns two I2C into four through the use of two I2C mux chips.

This board talks to all I2C sensors on the RS16 submarine.

Made a modified NodeMCU with connector for OLED and Distance Sensors. Sorry its slightly too wide for a breadboard. This is my very 1st board so I’m just experimenting.
