OK, that makes good sense. Try Folkestone Engineering Supplies, a company I've used for small amounts of "stuff". They have no minimum order and they just happen to have some 1/4" copper (your #4 is just a little smaller than 1/4"): http://www.metal2models.btinternet.co.uk/Copper.htm Have you got a lathe? If not, I'm not far away if you need the ends machined. > I can see two possibilities - either the 2.5mm wire will work fine, or it > will blast itself apart when the capacitor array dumps 50-odd (or was it 70? > need to crunch the numbers again) watt-seconds through it. I'd guess the electrodes won't be very long, and the pressures won't be very high for this spot welder, but 2.5mm might also bend. -- Pete Peter Turnbull Network Manager University of York

And I'm sure there's a few Mass residents on the list too. It 'twas in jest. Though South of Concord does smell way too much like Massachusetts for me.

Freecycle: another route to free computer junk

It also made me think there could be >opportunity in aggregating and searching these giveaway mailing lists. My wife monitors the list for my county... and I get the feeling that a centralized list would work against the point of Freecycle. I have the strong impression that anyone sucking up the goods to resell or otherwise do anything other than fill personal use (and this would border on collectors hording items as well), is not what the freecycle movement is all about. So a cental list, that a reseller could monitor and have the resources to snatch everything of value quickly, would be seriously frowned upon. By keeping the lists smaller and more local, it helps bolster the general idea of being a good neighbor. That said, I do watch for computers of interest myself (I haven't snagged any yet however). But I also give back, just Tuesday I gave away an unneeded queen size box spring via Freecycle. And last night I replied to someone looking for a free PC monitor (but haven't heard back, so I gather they got a better offer then the 14" I have available). -chris <http://www.mythtech.net>

Anybody know where I can find a manual on-line for the item above? I checked Al's site but it's not there. This is an adapter that fits the model 29 Programmer and allows the user to program QFP PLDs. It has a socket for 20 QFPs and two sockets for 28 pin QFPs. Joe

Old Computer Rescue?

by marvin＠rain.org

In searching for radio gear, I ran across this URL and thought it might of some interest here. I don't recognize it, but it looks like it might be some older computer stuff. http://www.geocities.com/heftyharry/OLD_COMPUTER_SALE.html
