Got some right here at work. some are nearly 30 years old. It’s a must have device.............
I've got some too, down in the basement. Also soldering irons, a signal generator, a digital oscilloscope, and a lifetime supply of old-fashioned rosin-core solder.
I never get to use it, though. All my design work is done in software now. I miss electronics, but I can create so much more functionality per unit time in software now that the hardware side just can't compete.
I miss it, too, because I'm a pretty good designer. Analog, digital, noise suppression, high-gain, high-bandwidth, opto-electronics, all that stuff. The thing is, it just doesn't pay to design it when you can invariably get a chip that can do it.
Then there's VHDL, and that whole world. Ah well.
At 30 years old it’s probably time to peel of the backing and remove the tiny metal particles that can end up as shorts.
The one I use these days is 12”x24” and it is nice to have.
Had the tiny one in college and it got a bit crowded!
