Two new Raspberry Pi Zero add-on boards

August 30, 2016

I’m very pleased to show off our latest Raspberry Pi Zero add-on boards.

RPio_PIIO_ADC16_UserP0rt_small

The board in the top of the picture is PIOO UserP0rt which features a 16-ch port expander and 8-ch ADC using the MCP23S17 and MCP3008 ic’s.

While the board in the bottom of the picture is PIIO ADC16 which is a 16-ch ADC board and features 2x MCP3008 ADC’s (each 8-ch, 10-bit).

You’ll find them on our Tindie store real soon.


ESP32 links

July 29, 2016

The WIFI enabled ESP8266 is one of those great chips to quote an old tradesman’s saying “it just does what it says on the tin”.

It’s only been around for a few short years but it’s made a great impact in the boom in WIFI enabled projects and products.

Building on this success of the ESP8266, Espressif announced the ESP32 late last year (2015).

As well as WIFI the ESP32 also features:

  • Dual Core 32-bit Micros
  • RAM 512KB
  • ROM 128KB
  • WIFI
  • Bluetooth
  • Ethernet
  • UART x2
  • SPI x4
  • I2C x2
  • I2S x2
  • SD/SDIO
  • CAN
  • GPIO x36
  • ADC 12-bit x16
  • DAC 10-bit x2
  • PWM
    and more

With the ESP32 August release date fast approaching you can now find more solid information on its capabilities. Here’s a few links to wet your appetite:

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.


    R-Kade Mini pictures

    May 30, 2016

    It’s been a while since I last wrote about R-Kade Mini so I thought I would share a couple of new-ish pictures. These were taken at Maker Faire UK in April.

    Instead of painting the cabinet I used black clothes dye instead. I’m please to report it work much better than I thought it would, giving it a nice flat black finish with no brush marks or paint smears. The decals were a mix of ones I printed off and some I bought off ebay. All in all I very pleased how it all turned out.

    Maker Faire UK 2016

    April 29, 2016

    Some 10,000 visitors and 300 stands, workshops and talks later Maker Faire UK 2016 is over for another year.

    As usually it was great to meet up again with Aaron of Oomlout, Mike of Grumpy Mike fame, Mitch Altman, Dominic and Martin from Just Add Sharks, David from abx-labs and Simon from ClarksArcade. As well as the old faces I also got to meet the guys from Leed’s Hackspace and also the guys from York Hackspace for the first time.

    I was on the Maker Space (Newcastle) stand again this year. Lots of cool members projects on display. Myself I had my Raspberry Pi based R-Kade Mini arcade and the R-Kade Zero. Both were received very positive comments from the people playing on them.

    Takeoff-RC had their drones on display in the open air exhibitor space.

    A special mention must go to Iain, Chris, Alistair and Tommy from Maker Space for their truly awesome Penguin Run project. It deservedly won the Maker Merit prize from the Maker Faire UK organisers.

    Only 12-months to the next one.


    Edinburgh’s Mini Maker Faire 2016

    April 21, 2016

    A little bit late, but we went to Edinburgh’s Mini Maker Faire earlier in the month (10th April). It’s been running now for 4-years and I glad to say we’ve been to all four.

    For the third year now, we were active participants and we had a Maker Space stand. Glen took his Egg-Bot and drones, whilst I had brought various R-Kade Zero prototypes and R-Kade Mini, my 7″ LCD mini bar arcade.

    The faire was well attended both by exhibitors and visitors. With the drones, egg-bot and R-Kade’s being popular.

    We meet up with the guys and gals from MakLab and Edinburgh’s HackLab again. We also met the makers from the Dundee Maker Space for the first time and I also met Laura from Raspberry Pi Foundation for the first time. She’s also wrote a nice blog on the faire and you can read it here. I actually get a mention🙂.

    Next one, is my local faire Maker Faire UK in Newcastle on 23/24 April.
