A cheap manual suction pen for handling SMD parts: [via]
Ah and wrt “suction pen” – I made the syringe with vacuum pump and it works but I don’t like it, I found then for 3.5$ a working device that does not require power and works like a charm I strongly suggest everyone get one

This instructable describes how to mount a VU meter into a case of an old cd-rom drive and then put it into your pc.
On eBay I bought a bunch of VU meters based on VFD displays build in Russia. The displays where rather cheap and looked nice. I thought I’d give it a try.
When the vu meters arrived I realized that on all devices there was one transistor missing. To make them work again you need to “repair” the vu meter … don’t panic you can easily solder a substitute transistor onto the pcb.

Here is a really cool item!!! These are new high resolution full color led display modules that were manufactured for the gaming industry to be used in slot machines and other similar gadgets. These displays are comprised of a 24 x 72 matrix of tri-color leds…that’s 1728 3.6mm rbg leds. The leds are spaced 5mm on center…as far as led displays go, that’s pretty tight.
