    Martin.M: I used to carry a little battery powered Tektronix scope like I see on your shelf when I used to fix Atomic Absorption Spectrophotometers for a living in the 80s. :beatnik:

    I added an HP 653a test oscillator, an HP 3325B synthesizer/sweep function generator, a Fluke frequency counter and an HP 0-60VDC 1A bench supply recently. The cool part is that they came from a truckload of surplus telecommunications equipment I took in a couple of years ago (and they all work, too!) Too bad there wasn’t a distortion analyzer in that load, as well!

    The age our electronic equipment kinda dates us as owners, huh?

    Here's my bench. It's mostly purpose-built for electronics work, but it resides in my garage. So it gets used for everything.

    The bottom is a nice deep surface for working on large TVs. I built in two Waterloo toolboxes underneath with various electronics emblems on the drawers (held on with magnet-tape). The bench top is MDF, and I counter-sank a home-made swivel for my magnifier light. That way I can pop it off and still have a smooth surface. Ideally, nothing has a "home" on the bench top. I wanted it to be open completely for working on large TVs.

    The top is a test fixture of sorts. I was motivated to build this because I was tired of the mess each of these items made on the bench top. I wanted one place where everything was built-in, connected, and ready to use, without junking up my bench top. The box has a 19" LCD in the center, with the input jacks routed to the patch plate on the left (there is also a tiny hole where the remote signal passes through). It is flanked by two 4" LCD monitors too. Why? Because I had them in my parts bin, lol. And it's nice to be able to test multiple streams simultaneously. I used plexiglass to cover each of the monitors, with back-painted black trim.

    There is a large server power supply inside the cabinet to provide 12v and 5v to the banana jacks (this also provides power to the ancillary video devices). There are 4 4-ohm speakers wired to a terminal plate for testing audio devices. I can pair them up in series or parallel if I need 2 or 8 ohm loads too.

    Across the bottom from left-to-right I have a SD-Card video player, it has 4 HDMI ports, a VGA port, a component and composite output too. This provides test videos for when I do burn-in testing on TVs. The second white device is also a SD player but it only has VGA and composite. I use this one for stills and test patterns. Then on the right is a small car amplifier that I use to test speakers.

    There is a fan on each end of the cabinet to pull air from the nearby AC vent through the cabinet interior for cooling.

    I have a couple blank plates in there for future expansion. I might add a variable power supply at some point. The monitor on the back wall is just for security cameras. And of course the trusty Tektronix scope on the right. There is also a PC in the rack to the right (not pictured), but that's what's displaying on the LCD (Will Ferrell's "You're Welcome America")

    Total cost for me was about $150. I had all of the parts in my junk bins. The only thing I had to buy was the wood, the plexiglass, the two Waterloo boxes (black friday sale $35 each!), and the AV jack plate.

    Sorry for the crappy cell phone pics.

    thats my hobby, to restore them ..
    one of the most amazing Tek is the small one with the black frame.
    This glowing Tek works with Sampling Sweep + Sampling Heads, the GHz-Voodoo of the RockNRoll Era..
    In the scope mobile of the 551 Dual Beam is a 1L5 Plugin, this is a complete Spektrum Analyzer System for the Audio Range, also build in the late 60s

    But there are differences as well. For instance, I've never pissed in my bench because I had too much to drink. :no:

    FTR, I've never pissed in my pants either... just couldn't resist!

    LOL, I think you guys are being generous. It's messy and a bit cluttered.
