The low cost and easy to make Mighty1284P WiFi DIP Module for breadboard prototyping. Made with all through hole components. Use the new core and exact same pinout of the original maniacbug Mighty 1284P 16MHz prototype board. Other features include the ESP8266 connector, reverse polarity protection diode, reset button, and D13 LED indicator. See details at: http://www.firebirduino.com/mighty_stick/

Pressure & Valve Controller Arduino Shield

53.125 MHz 3rd Overtone VXO

XBee Board. Includes 2.54mm screw terminals for two sensors.
1. One is active low, using the xbee pullups. This is a two wire hook-up, simple switch (DIO and ground).
2. One is powered and assumed active high, with internal sensor pulldowns. This is three wire hook-up (DIO, positive, ground).
3. Micro USB connector to provide power only.
4. LEDs for power and RSSI.
5. Works great.
6. Use one on my mailbox under battery power with one reed switch.
7. Leave the power LED unpopulated for better battery life.

1. Uses an ATTiny 25/45/85 8SOIC to control common LEDs (WS2801 or APA102).
2. Reset button advances sequence in code, with pins included for additional remote reset button.
3. Program with 8SOIC Test clip, there are no ICSP pads.
4. This is very small.
5. Works just fine 3.3V and 5V. One Li-Ion battery is perfect.
6. I am using these in various projects. With a 20 mhz resonator they can do some impressive POV effects in flow toys (poi/staff).

MPU6500 6-axis motion sensor plus AK8963C magnetometer plus BMP280 pressure sensor with the SENtral EM7180 sensor fusion hub with M24512DFC EEPROM to store the SENtral configuration file. SENtral takes 9-axis accel/gyro/mag data from MPU6500 and AK8963C and performs hardware sensor fusion returning raw data, quaternions, linear acceleration, and heading, etc. Breakout board using the SENtral with jumpers to take power from edge pins for breadboard use or to mount directly on the Teensy 3.1 for comparison between open-source software sensor fusion and the hardware sensor fusion provided by the SENtral. SENtral can act as master to BMP280 pressure sensor and in the future include the pressure data in the sensor fusion.

Proto for Unipolar Stepper Motor Driver. Powered by 12VDC and 5VDC 3A linear regulator. Includes overcurrent detection set to currents greater than 1.75A and RED LED indicators.

nRF51 BLE dongle

Odds are high that it won’t stay at the 5000th position for long due to churn, deleted boards, etc. But it’s nice while it lasts. Will add screenshots [later] to prove if it indeed got the #5000th position (at the time). #ToEdit
What a neat milestone for OSH Park!

$10.60 / set of 3. Untested, but fully expected to work, and I decided to go ahead and release the next (smaller & simpler) version first, as it’s probably more versatile. I just sat on this design til now.
Works for either SMD or thru-hole DIP packages of amplifier IC. (note SMD=0.4W & DIP=1.4W Pd-max)

Uses 3x2 header for volume pot,
5 large electrolytics=470uF 10+v,
2 small input ‘lytics = 4u7 25+v,
input load R6 & neighbor= 10k (x2),
input bias R4 & R5= 3k3 (x2),
all 4 ceramic/film caps =0u1 25+v,
output snubber R (next to C10, C11)= 4R7 x2,
power led & R (between snubber-R’s)= 4k7 [both optional, if you want to save power.]

Based on adafruit INA219 current sensor breakout board, this board is used to log on SD card the power consumption of other devices. UNTESTED! order on your own risk.

$7.55 per set…for my Modul-Ar-duino, uses FT232RL and either USB mini-A or Std.-B connectors
Has 3v/5v IO jumper, DTR/RTS jumper and cap after it for arduino auto-reset (optional shorting jumper too).
Edit: Bug in Ground plane polygon fills - isolated by Eaglecad from the vias. Was learning how to use polygon tool at the time. Noob symptom, sorry.
