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.

3R2 Motor Interface board

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.

Atmega328p-based 1200 Baud AFSK radio modem

MicroModem MicroModem is an open-source implementation of a 1200-baud AFSK / Bell 202 modem on the popular ATmega328p microprocessor. MicroModem can be used for things like ham radio APRS, AX.25, TCP/IP over SLIP, experimentation with mesh-networks, long-range wireless communication with sensors (Or friends! Or strangers!). It basically comes in two flavors: Prebuilt or DIY.

It is simple enough that, if you have some basic electronics experience, you can understand and build it yourself with a few components and an Arduino. You can also get a more advanced and prebuilt, fully tested MicroModem directly from original designer. He manufacture them personally, to the highest quality. (link/store at his site)

Please note that the resources listed here for building your own MicroModem are for an earlier, more simple version, than the one he currently offers for sale. While the two modems are functionally identical, the version he offers for sale has some technical refinements, and is implemented as an integrated board with MCU, USB and everything on one board, measuring only 3×5 cm. The DIY version is a board with all the external circuitry needed for turning a standard Arduino (or compatible like Microduino) into a MicroModem!

This is my adaptation of the MicroModem DIY, it is upsized to the footprint of the arduino nano (I got one for $2.99 vs the $18 it would take for the MicroModem Core USB), this is a conversion and should be a 1-1 pinout match for Marks MicroModem (so his pre-compiled hex files should work with no modification or need for re-compile) but for the MUCH cheaper arduino nano.

Correction for missing trace, and for the used arduino nano library to correct reversal of analog pins.

-untested- at the moment

Small adapter board for use with the Open Panzer Tank Control Board (TCB). On one end of the board you solder the leads from a 5-pin JST-XH pigtail, on the other end a right-angle Molex Micro-Latch connector. This allows the Tamiya IR receiver or “apple” (Item #53447) to be plug-and-play with the TCB.

See the Accessories page of the Open Panzer TCB wiki for more information.
