I am demonstrating the use of my ‘home-made’ IR Pen or Wii pen using an application called ‘Cooliris’.
First thought that enters my mind is ‘Minority report’ – this device brings a different depth to using the PC, a rather pleasant interactivity that really shows well in Cooliris.


This is my home-built version of the IR glove.
The setup is basically; blue tooth dongle (blue soleil), wii mote, wiimote whiteboard software to calibrate and a golfing glove that incorporates a battery and a strong Infra-red LED at the tip of the finger, activated by a micro switch.
When playing DCS: Black Shark, a helicopter sim, it adds to the immersion and ease of controls when in the cockpit as every switch can be clicked using your hand – this eliminates the tedious mouse control and/or keyboard commands.
If you can’t afford to buy control boxes etc then this is ideal – with some basic knowledge, simple instructions and materials costing less than £10.

I really like this Casio from 1975 – unique landscape design.

I received three calculators today! The futuristic looking Rockwell ‘the 24k’ (1976), a Radofin 2200 style 2 (1975) and an immaculate Hanimex ESR 80 (1975) in it’s original packaging.

I have just acquired some more retro 70’s calculators, they can be seen here
This week; Rockwell ‘The 24K’ (1976), AML Traveller LE-8 (1971), Sinclair Cambridge Programmable (1977) and Sinclair Cambridge Type 3 (1975).
Today, the Hanimex ESR 80 and the Radofin 2200 – Pictures below.


I am starting a new page called ‘retro calculators’ – still in development but will catalogue my own growing collection of 70’s calculators!
The various designs are very interesting and worthy of preserve, both for historical and factorial reasons.

Stay tuned 🙂



I don’t see this as the iPhone app to take over from Twitter but do find it a useful addition or aid.
Some things can’t be explained so easily through a text message, such as sound for instance. This is where audio boo plays it’s part.

Stephen Fry uses audio boo – he was recording questions for his twitter fans.

It is still in development and viewing the website forums there are a lot of good ideas coming forward from the public.
