Hi all.
Due to being out of work I am clearing out most if not all of my elements and alloys collection, as well as a lot of other stuff.

I have for sale:-

LED collection including a PCB full of SMD UV emitters, will throw in a nokia 3310 display or two if anyone wants it
4 identical 2cm screen digital picture frames with 8 pin 1 MB Flash and lipo 150mAh batteries, plus a spare dismantled one
Three used, salvaged but functioning Peltier modules of various sizes.

Non functioning dual channel 120V power supply, never managed to find a 240V transformer for it.
Functioning 2.4GHz Black Star frequency counter, with batteries

Two miniature Geiger tubes, I believe they work (tested one a while back) along with the zener diodes if I can find them.
Bull Electrical geiger counter, needs some TLC but does count.
Fairly large multicompartment box of assorted parts including some laser diodes and phone salvaged white SMD LEDs on flexible pcbs
Various chemicals, including barium carbonate, copper oxide, ammonium persulphate, PCB developer, part B of some photography developer kit, 300 mesh iron powder, boric acid granules, etc.
Some copperclad PCB including double sided.
Spray on photoresist
Small quantity of surplus white EL wire, some green but has patches not working.
Couple of B/W camera PCBs, seem to work but have attempted to fit tuning diode to one.

Box marked "surplus lenses and stuff" containing some small LCD panels from a projector with dichros and other bits.
Half full bottle of ferrofluid
4 High strength neodymium square magnets, along with some smaller ones.
4 possibly working and one faulty Acer Aspire One motherboards, known good display and most of the casing.
(maybe someone can build a netbook?!) no heatsinks on most but i tested them with the one I had.
Two of these boards have broken power connectors so I have grafted on a lead to the pcb stub.
May be useable for some sort of homemade notebook perhaps?
16GB AA1 SSD drive (unable to test, may be broken!)
Bag of assorted small used LiPo's
About 12 or so 350mAh LiFePO4, unable to use due to no charger.

EDIT:-

Fist sized very interesting looking piece of silicon carbide.. have managed to get light from some areas.

In addition I have a very large box full of apparently DOA LiFePO4 18650's.
You would need to hand sort these cells to find the good ones, around half most measure around 1.4V and are almost certainly beyond repair unless someone has a clever charging protocol.
Unsure why they were so bad but they may have been defective from manufacture.

I also have those three weather balloons left if someone has a use.
If someone happens to need them I also have some titanium, tantalum wire, and whats left of that EL kit (around half the green/blue phosphor and dielectric with some silver paint left)

Make a sensible offer on any/all of this stuff via PM.

regards, -A

I'd be interested in the 1TB laptop HDD. Posting here rather than sending a pm since this is relevant for others too: Are you in the UK or in the US? Nevada and Â£ don't really fit together...

Sometimes he thinks he is in Area 51 but it always turns out to be Guernsey in the end.

Not exactly, the UV LED part worked fine but I couldn't find a high enough resolution digital picture frame with adequate transparency.

Might have worked with a 3310 screen but again the resolution would suck.
So back to Press & Peel it is.

I'll take one of the weather balloons and maybe the half bottle of ferrofluid. Thanks!
