PropBerry – Propeller & Raspberry Pi combo

July 31, 2012

For PropBerry, I was thinking using a Parallax Propeller* (or just Prop) as a super i/o co-processor for the RPi where the Prop would be used to offload the real-time I/O and let the RPi handle the higher program features. After talking about this combo on the Parallax forums, the Props VGA video capabilities were mentioned which got me thinking about using the PropBerry as a VGA serial terminal console and shelve the i/o co-processor idea for now.

The Parallax community is great and they’ve released a lot of good stuff. One of the things I remember (from about 2009) was Vincent Briel’s PockeTerm terminal software for the Prop. Using this on a Propeller Demo Board gives us a VGA video output and PS/2 keyboard for user input. A serial interface connects the Propeller demo board to the Raspberry Pi.

Now we got our bits together lets see if we can make them work 🙂

* The Parallax P8X32A Propeller chip (or just Prop) is a cool chip. It is a multi-core architecture parallel microcontroller with eight 32-bit RISC CPU cores (cogs) which share a common hub of 32K-RAM


Maker Faire UK 2011

March 15, 2011

The Maker Faire UK was back at Newcastle on the weekend 12th and 13th March 2011.

This year Abs and Sid were actually looking forward to going to the Faire, no arguments or huffy pants, in the back of the car they jumped and off we went.

This years Maker Faire as definitely bigger and better than last years. More floor space, more stands and more visitors.

In the makerspace, Abs decided to build a Maker Faire UK 2011 LED Badge, a RGB light thingy and a Drawdio noise making pencil. While Sid built the same LED badge and RGB light thingy but chose to build a LED light cube instead of the Drawdio.

It was great to meet some old friends and makers:

Aaron from Oomlout was there with their Arduino boards.

Jim and Kat from Sonodrome with their 555 step sequencer and their newest project an AUV (looking forward to seeing it fly Jim 🙂 )

Brian from Lab in a Box showing off his chemistry skills with his college showing off an early version of the OpenPCR.

Oli was there again with his interactive light table

John brought his UK101’s again and a new or should I say “old” Roland plotter churnning out coloured drawings.

and some new makers

Mark founder of Minty Geek was showing off their neat electronics kits.

Malcolm from Weird Motors with an array of homebuilt electric vehicles

Dave from BodgeitQuick with an impressive homebuilt RepRap

Martin showing off his mini ROV’s.

The legend poster that is Mike Cook (aka Grump Mike) from the Arduino forums showing off his Electric Harp and Hexome Arduino sequencer.

The world renouned hardware hacker Mitch Altman was there again working the maker area, helping the young and old to get making. The old guy from the Gadget Show was doing the rounds with a camera crew.


Sharing Project Files

February 24, 2011

One of the things that bugs me about wordpress.org is you can’t attach zip files or any file format that’s not a picture or word doc or pdf to your posts. This is a problem for me when I want to share schematics and PCB layouts of the projects I’m working on.

So I’ve been research for other ways I can share projects files through this blog.

There’s loads of online storage and collaborative sites I could choose from but I’ve narrowed the list to these four:

www.box.net

www.github.com

code.google.com/

www.codeproject.com

box.net is the favourite of the wordpress forums, a lot of Arduino project people use github.com and code.goggle.com and codeproject.com are popular amonst my programmer friends.

So which one to chose?


The ZX Spectrum ULA: How to design a microcomputer

December 29, 2010

I’ve been following Chris Smith’s zxdesign.info web site for a number of years. His redesign of a ZX Spectrum ULA using only logic IC’s was an awesome achievement.

In addition he’s wrote a wonderful account “The ZX Spectrum ULA: How to design a microcomputer” on the forerunner of programmable logic – the Uncommitted Logic Array (ULA). I was lucky enough to get his book as an early Christmas present and I found it a great read.


Pocket DSO

September 7, 2009

Seeedstudio have been teasing users on the Ardunio forum with advance product news of a really cool pocket DSO.

DSO

The DSO mobile is a pocket size digital storage oscilloscope base on ARM Cortex™-M3 compatible 32 bit platform, equipped with a 320*240 color display, SD card interface, USB connection, chargeable batteries and weighs only 60g!

If it’s spec is half as good as it looks I know what I want for Christmas.
