Proto-PIC a good source of bits for all sorts of projects, AND medcial equipment repairs.

Managed to save the NHS about £700 by getting parts from them instead of the manufacturers. A certain model of Mobile X-Ray machine uses pressure sensitive resistors in the handle mechanism to control the speed & direction of the machine. The replacement assembly cost about £350 per side. THe PSR's from Relchron cose about £5 each, 4 required for complete set. Might have to revisit the "gouge" post

Good Man, Bill ... that's the spirit! smile

BTW you might be interested to hear that I got an email from the folk at RelChron thanking me for my earlier link to their site.

I bought myself an Arduino Uno starter kit from Rapid a few weeks ago and find it very easy to use. Look on it as a breadboard-ready microcontroller system and I have found it useful to test the LCDs that I took off scrapped medical gear years ago.

It's been a while since we heard from you, Jonathan ... hope you've been doing OK. smile

Be sure to keep us informed about your projects.

At this stage I should probably "come clean" and declare that I haven't got hold of any of the aforementioned proto-boards* yet (to be honest, I just don't seem to have the time to fiddle about with stuff like this these days). But - for the time being at least - remain an "interested observer".

* I've still got a (traditional) breadboard in one of my toolkits, though. And probably actually used it once or twice [in ten years]! LOL

A bit of advice when using old breadboards, clean the contacts! I've had all sorts of problems in the past caused by high resitance in the contacts.

Not to mention the bread crumbs! whistle

As many will be aware, there is plenty of stuff about proto-boarding on the web; but for a quick look (and a way of keeping tabs on what's going on) - why not check-out the guy who wrote the book! smile

Why do foreign names sound so much more interesting than their English counterparts?
The Arduino "Duemilanove" actually means 2009!
Giuseppe Verde sounds much more exotic than Joe Green!
Fiat Cinquecento or Fiat 500?

Why the Austin Allegro, the Ford Fiesta, the Capri, the Vauxhall Corsa ... or even the Morris Ital (remember those)? OK, some of those are (were) made overseas. Hey, how could I forget the Cortina, or the Sierra? (Mondeo?) ... the list is almost endless!

What was wrong with "13/60 Mk II"? LOL

How come Melvyn Bragg was gushing over the accent of his Italian guest following the recent episode of "In Our Time", rather than remarking on how clued-up the lady was?

You've been in the Middle East, Bill ... how many farang go for dusky Asian maidens?

Opposites attract? Human nature? The mystique? You tell me.

Who knows ... even "Mr.Bill" might sound exotic to ears from afar. Eh, hombre? think

Doubt it, it was hard enough to get them to say Bill instead of Pill.
