Re: When PCB's are too expensive, and you're out of copper boards.
I've built rigs on flattened soup cans. If you're brave enough (or dumb enough) to go at a can with tin snips and gloves (and eye protection!), tin plate is very easy to solder to and build on.

Re: Tayda Electronics and parts, heatsinks, Octopus
I'm a big fan of Tayda. I've been buying from them for several years, and they are my primary source for resistors and capacitors. Their prices are very good, their shipping is very reasonable, and

Re: Tayda Electronics and parts, heatsinks, Octopus
To me it is a service to the amateur radio and experimental builder community to provide small quantities of quality parts at reasonable prices and shipping.? I don't believe they make any profit

Re: Tayda Electronics and parts, heatsinks, Octopus
My needs are simple Daniel, so I got a Hantek DSO5202P dual channel 200MHz 'scope. Comes with 2 probes, and all for just $299. I was happy with it, except for one thing. When using the Autoset

Re: 2N2/20 Scratch-Build - Progress So Far
Thanks for doing that Chuck, and it's good to know that we don't have to worry too much about mounting our toroids close to the board.

Re: Honbay trimmers; I took one for the team
You can buy Jameco CTC-50 caps on Amazon.com, but I'm not sure if they are $9.74 for 10, or $9.74 each - lol.
