I enjoy thinking of the arcane hardware they will need if they ever seize my computers. Please make sure to gouge them for every last cent when they have to acquire a phloopy drive or IBM MagCard drive on ebay. BRB just going to write 'List of targets' on my jar of loose ferrite memory cores.

I find the ones with 5 flux cores (or 3 for the 0.23mm thin solder) seem to melt easier than some with 1 flux core but the same alloy. I'm in Australia, I could post you a short length of each size to try first if you like, (since a whole roll is $$$). - DM if interested

I prefer the ones with more cores of flux in them - they make some with 1 flux core, but the ones with 3 or 5 cores seem to work better for me. The price seems to be very variable depending on country and distributor. e.g. this one looks good to me: cpc.farnell.com/multicore-lo...

I like Multicore 96SC but it is hideously expensive (e.g. uk.rs-online.com/web/p/solder... ), so best if your employer buys it! Sometimes it is on special offer, a bit cheaper. I have 0.7mm, 0.5mm and 0.23mm. I pretty much only use this stuff now, and seldom have any wish to use leaded.

Ooh, nice!

That's one way to put a permanent stop to the disinformation!

Coils from dead or surplus relays are a good source of enamelled wire for prototyping. It's hard to buy 0.03mm - 0.2mm wire in small quantities, but a relay coil is enough for a lot of prototype wiring (dead-bug BGA chips etc.)

I used to wish for a giant vacuum cleaner truck, like they use with the pressure washers to dig around pipes.
