Inspired by electronics repair videos on YouTube, [Steven Leibson] recently found himself hunting down something to fix on eBay. This ‘something’ ended up being a certified classic: a Keithley Model …read more Continue reading Fixing a Malfunctioning Keithley Model 179 Digital Multimeter
If we had to make a guess at the single piece of electronic bench equipment owned by the highest proportion of Hackaday readers, it would not be a budget oscilloscope from Rigol, nor would it be a popular portable soldering iron like the TS100. Instead we’re guessing that it’s a …read more
When a fine piece of lab instrumentation crosses your bench, you’ve got to do your best to put it to work. But even in the highest quality devices no component lasts forever, especially vacuum tubes.

At the same time, there are some tools that simply must be stored away, and can’t perch on my workbench forever or sit on a shelf.
It really is a balancing act sometimes. I don’t have a …read more
