Added GND plane connection to antenna for poor man’s dipole.

Laser TA Board

Through-hole resistor breakout board. The large resistor footprint accepts up to a 1 Watt resistor. The 2-pin header accepts standard 0.1" breakaway header pins.

Much OSH Park, don’t you think?

Simple prank device, functions like the annoyatron.

Universal programmer board

29F032 or other 32Mbit TSOP to DIP42 8bit adaptor. Designed for use in repairing NEO-GEO cartridge V-roms that require 32Mbit (4MB) rom replacements. Jumper settings on the board allow you to select which mode you are using the adaptor, programming or reading (place jumper between MODE and PRG to program, and MODE and RD to read).

Allows for programming of 29F032 or other 32Mbit Flash once soldered to the DIP42 adaptor board. Supports the GQ-4X programmer pinout (no need for the extended address headers) as well as regular DIP32 pinouts with address headers via solder pads for pins A19-A21.

This is a small adapter board to use an HC-05 or HC-06 bluetooth serial adapter for rig control of a Yaesu FT-817. SJ1 is used to provide V+ to the adapter to enable AT command mode on an HC-05. R1-R3 are identical values, and are used to convert the 5v TTL signal from the 817 to the 3.3v signal expected by the bluetooth adapter. R4 is the current limiting resistor for using an HC-06, R5 is the current limiting resistor for the status LED for an HC-05. R4/R5 may be omited if you do not desire having a status LED. The voltage regulator is a AMS1117-3.3v or LM1117 3.3v regulator. This board is designed to be able to be left on the radio, even when it is standing on the back end, and not interfere with any other ports. Please note that the FT-817 leaves the port powered at all times, so it may be advisable to leave the LED off if concerned about power consumption. The bluetooth adapter itself is rated to consume 10mA while actively paired, and 30mA while disconnected, according to the datasheets I have seen.

Test Project to use OSH Park - DO NOT PRINT

These are motor mounts for the jumper 260 plus quadcopter. The stock motor mounts are made from 1.4mm single sided PCB. They are cut near mounting holes to look “pretty”. My redesign removed the cut out and adds copper pours on both sides to increase strength slightly. LED’s are retained, You will have to remove LED’s from old motor mount. There is a 330 Ohm current limiting resistor in series with the supply to motor mount. The supply is 9 Volts.

Display driver board for a esp8266 clone or the like, with 5V linear regulator onboard, 74HCT125 buffer, and a 5 pin, 0.1" header out to the microcontroller thingy. Also, a friendly smiling U+1F4A9 PILE OF POO.
