It was with great sadness that I read that Maker Faire UK will not be coming back next year.
The venue Centre for Life in Newcastle has hosted the maker event since 2009 and was the very first venue to host a Maker Faire outside of the United States.
I’ve been a regular visitor and exhibitor since 2010 and enjoyed every moment of my time at it.
Fortunately, there are still plenty of other Mini Maker Faire’s in the UK and I’ll hopefully be visiting some of them next year instead.
So a final thank you to Maker Faire UK, to the people who organised it, to the exhibitors who showed off many great projects and to the many visitors who came to see what it was all about.
Here’s the message from Maker Faire UK web site:
In 2009, Life Science Centre brought Maker Faire to the UK and has hosted the country’s flagship event ever since. Over that time, the popularity of making activities in the UK has sky-rocketed.
Life is proud to have been pioneers in this growing Maker movement, but we feel the time is right to make a change and to bid a fond farewell to Maker Faire UK. Lovers of all things making needn’t fear, as we’re opening a new space in Life Science Centre dedicated to crafting, tinkering and creativity in the spring of 2019.

I found this snippet of knowledge from the Raspberry Pi forum the other day when searching for a easy way to shutdown a RPi from a simple push button.
Open /boot/config.txt in your favorite Raspbian editor and add the following line:
You may need to add a pull-up resistor to the GPIO pin or add the instruction gpio_pull=up to the instruction. You can also leave out the gpio_pin and the system will default to GPIO3.
You can also monitor the RPi’s status by adding this line to config.txt:
GPIO27 will be high to indicate when the RPI is running or low when it is shut down.
There is more detailed information here:

A few months ago I mentioned a 8031/8052 CPU card I had designed for the RC2014 bus. Here’s a couple of pictures for an assembled card. I’m just starting to test it out so I will post results shortly.

When design and building my recent RC2014 boards one of the things I’ve found most useful and fun to re-read them after so many years has been my collection of great old tech books and data books. You’ll probably recognise a few of them. Here’s a brief list in no particular order:

I recently came into possession of a Apple IIe (an enhanced Apple II from the early 80’s) and decided to build a few PCB’s to help get this old warhorse back up in running. The first board designed was an extender card for the Apples expansion card to make testing and fault finding them a little easier. The second PCB was a prototyping board to allow me to build up various test circuits.
Both will be available on Tindie soon

I got a bumper box of PCB’s in the post today, just in time for Maker Faire UK 2018 this weekend (29th/30t April 2018).
Inside the box were some new RC2014 boards. The first two new PCB’s were my respins of a Z80 SIO/2 serial board and a Raspberry Pi Zero terminal board, as well as two brand new designs.
The first brand new board was a RC2014 RS232 breakout board allowing TxD1/RxD1 and/or TxD2/RxD2 serial signals from the RC2014 bus to be driven at RS232 levels.
The second brand new PCB was a new 8052 CPU board. This is a bit of an experimenters board as the 8052 bus architecture doesn’t directly map onto the Z80 bus architecture. When using the 8052 CPU some of the Z80 control bus signals (!M1, !MREQ, !IORQ etc.) will need pulling low via jumpers when attempting to make use of other cards. So why all the fuss. Well, the 8052 CPU does have the excellent the 8052-BASIC available which does make it a fun and a powerful (in 1980/1990 micro terms 🙂 ) system.
