Sick of Beige (SoB) board – DB9

January 9, 2017

Whilst looking to build some breakout boards I remembered the Sick of Beige (SoB) “standard” of PCB footprints designed by Dangerous Prototypes. DP have made a really cool set of PCB footprints in various sizes with the added bonus of being designed to be case friendly.

Dangerous Prototypes have a great page describing the various PCB sizes here:

My first Sick of Beige (SoB) board is SoB DB9, using the DP5050 footprint. This is a handy little breakout board for those wanting to build their own 9-way D-Type interfaces be it for RS232, RS485, CAN bus or any other project.

A standard 9-way D-Type (Male) connector provides the interface with 3.5mm Screw Terminals connections provided for easy interfacing. In addition a Male Pin Header connections is also provided. Two small circuit prototyping areas are also provided.

Board Details:

– 9-Pin D-Type connector (Male)
– Easy to Connect Headers
– 3.5mm Screw Terminals
– 2.54mm Pin Header
– small circuit prototyping area x2
– Compatible with Sick of Beigh DP5050 footprint
– Board Dimensions: 50 x 50 mm
– 3.2mm Mounting Holes x4

Uses:
– Industrial Control
– Robotics
– Mechatronics

As usual you can find them on my Tindie page here


WIP – new RPi Zero add-ons

June 29, 2016

This last month I’ve been working on some new add-on boards for the Raspberry Pi Zero.

In no particular order:

  • ADC16 – 16-ch ADC board (2x MCP3008 8-ch, 10-bit)
  • UserP0rt – 16-ch port expander and 8-ch ADC (MCP23S17 and MCP3008)
  • Relay2 – 2-ch Relay board (2x Relays 30V, 1A)
  • I’ve just sent these off to be manufactured, so I’ll post an update when I’ve got them back.


    Four new Raspberry Pi Zero add-on boards

    January 18, 2016

    Another bunch of new PCB’s. This time for the Raspberry Pi Zero.

    RPI_PCBs_201601_small

    In no particular order, there’s a serial RS232 board, a GVS I/O board with ULN2803 for servo’s etc., a Breakout board (I2C, SPI, UART and GPIO) and another MIDI interface ;-).

    More details/info shortly.

    As usually you’ll find them on our Tindie store.


    New RPi MIDI board and a new MIDI Breakout board

    December 13, 2015

    RPi_PIIO_MIDI_PCB

    I should have called this post “yet-another RPi MIDI board” as it’s includes my third iteration of a MIDI interface for the Pi. But YARMB doesn’t actually trip off the tongue 🙂

    So here we have a new RPi MIDI board. Briefly its spec is:

    • MIDI IN via 5-W DIN Connector
    • MIDI OUT via 5-W DIN Connector
    • 3.3V Operation
    • HAT foot print (65 x 56mm).
    • Four fixing holes.
    • ID EEPROM (not fitted)

     

    In addition to the RPi MIDI, there’s also a MIDI break out board (BoB) board. It’s spec is:

    • MIDI IN via 5-W DIN Connector
    • MIDI OUT via 5-W DIN Connector
    • MIDI THRU via 5-W DIN Connector
    • On board 5V Voltage Regulator
    • Size 80 x 49mm.
    • Four fixing holes.

     


    New Pi add-on board – RPi Breadboard+ for sale

    April 15, 2015

    RPi Breadboard+ is a solderless prototyping breadboard add-on for the Raspberry Pi. Using the breadboard and female to female wires you can quickly prototype and test your electronic design.

    A large portion of the add-on is taken up by a 140-pin breadboard and surrounding the breadboard on all four sides are a number female headers.

    All of the Raspberry Pi GPIO signals are brought out to two 16-pin female headers located near the top and bottom of the breadboard. 3.3V (5-pin), 5V (5-pin) and 0V/Ground (12-pin) power supplies are also brought out to female headers located to the sides of the breadboard.

    The add-on features 3x LED’s (red, yellow and green) and 2x push-button tactile switches each having a 2-pin female header for easy use with the rest of the board.

    Size wise it conforms to a standard HAT board size (65 x 56mm) and mounting holes. So its compatible with the Raspberry Pi A+, B+ and Pi2.

    There is an EEPROM PCB footprint for future HAT configuration compatibly but its not fitted on this version.

    R-Kade getting a upgrade

    February 27, 2015

    The wiring in my Raspberry Pi mini arcade cabinet is getting a much needed upgrade.

    I originally build R-Kade for Maker Faire 2013 and its been at various other Faire’s around the country and at eDay for the last two years. It was quickly build out of a bookshelves, old VGA monitor, WII arcade controller and a raspberry pi. The control board was removed from the WII arcade controller and the joystick and buttons wired directly to a prototyping board on the Pi. Unfortunately, it’s this wiring which is becoming a problem and needs redoing.

    Rather than just strip out the wires and rewire new, I decided to make myself a better solution and have designed a Pi ArcadeIO board. The ArcadeIO board has screw terminals for connecting the wires to the Pi’s GPIO signals. In addition the GPIO signals have in-line resistors to limited the effects of any short circuits. There are addition screw terminal positions for connecting common grounds for the arcade switches and joystick.


    Raspberry Pi (Beeb) UserPort HAT

    November 30, 2014

    Of the recent Pi boards I’ve made I think UserPort is probably my favourite. It’s a mimic of the BBC’s micros digital User Port and Analogue Port.

    Back in the 80’s (gosh that sounds old) I built many electronic, robotic and other projects using the Beebs digital User Port and Analogue so reproducing their functionality for the Pi was a pleasure.

    Digital I/O is provided by a I2C MCP23017 16-channel Port Expander
