I was thinking about magnets earlier.  If I was using a magnet to hold a bit of metal in place, could I rig the metal up as an electromagnet so it was the same polarity as the magnet as a quick release function?

Anyway, my last purchase was a batsocks telly shield (totally amazing. WORKED FIRST TIME!), a bag of one microF 250v caps (to replace the duff one on my 180v supply), a bag of random watch parts (in case I want to get a bit steampunk) and a shimano gear cog thingy for if I ever get round to making an imitation of that nice clock.

I've got a great project in mind for the telly shield but it'll wait til I've sorted my nixies out.

Haha, this popular thread is back!
I bought some stuff from Modern device. Haven't tested any of them yet, 5 RBBB PCB, 10 16MHz resonators, 1 3-axis accelerometer.
I am making a music box http://liudr.wordpress.com/2011/01/24/music-box/ and a POV.

Will test the accelerometer in a few minutes.

A hot air rework station. Haven't soldered with it yet but it make desoldering really easy.

Which one? I'll tell ya, it opens up a whole new sector of fun being able to work with smd packages like bga's. And of course there's blasting old boards with heat and then just picking off all those 0805's and 0603's resistors and caps and tossing them straight into the "extra parts bin".

I would heat up my old mobos and pull out those surface mount processors. I've been carrying them around since 05. Moved at least 4 times in between.
How much do they cost?

So far I'm real happy with it. The range of nozzles suck (!) but from what I can see they are all 21.5mm ID so I can get nozzles form other units.

That's what I've been doing, getting dead mother boards from computer shops. It's a lot of fun.

Jealous...

One TQFP ATmega328P - but it came in a box over a foot cube and mounted in a 250-unit waffle-tray all to itself!  A triumph of wasteful packaging...

Better safe than sorry

LOL - I once ordered a single 12 inch long CCFT from Mouser for replacing a dead one in an LCD monitor I picked out of the garbage at work; it came packed in a 36 inch long by 4 inch wide tube, wrapped with bubble wrap, with the CCFT itself inside another plastic carrier tube. It didn't break in transit though...

My last purchases came courtesy of Ebay:

- An AMD 386SX motherboard with 4 x 1 mb 30 pin SIMMs (for a future retro PC)
- 2x Via Epia M-10000 Mini-ITX motherboards, each with a stick of 512mb DDR (the price was too good to pass up)
- Actual packaged copy of Virtus VR for Windows 3.1 (I collect old VR gear and software)
- A SpyGear ATV-360 (I buy these when I can find them cheap for the Kopin head-mounted monocle display)

Last weekend I also picked up a variety of parts from Apache Reclamation (I swear, sometimes I feel like I keep them afloat, I buy so much stuff from them!); while I was there I spotted an awesome component: A large, still-in-crate NOS Ignitron from National. By "large" - the crate measured about 2 x 2 x 2.5 feet - it was standing upright, still bolted to the bottom, and all the metal straps holding the crate together in good tight shape, no cracks or other deterioration in the wood. It was a large stainless steel cylinder with large binding posts mounted on it for terminals, plus in the crate was a large inch-thick braided copper cable with similar sized copper lugs (the copper in that was probably about $100.00 worth right there). They were asking $1000.00 for the unit. Needless to say, I didn't bring it home (not that I would have a use for such a large rectifier).

Looks like there will be a lot of mercury inside it.

I know there are in the UK, not sure about the US.. But aren't there funky laws around mercury because of it's general toxicity and death causing attributes?
