Ok, Dude, you provoked.Getting dye now, training the batshit look
Quote from: Robert763 on July 09, 2021, 10:18:33 am I must get back on the FRK Rubidium build first....Now that is something I haven't heard in a very long time. I worked for Efratom when I was undergraduate at UCI. Maybe 1979?? They hired me because I was cheap labor. I wrote the program and built some of the hardware that tested them during the ageing process. As I recall there were ~10 of the cubes on test connected to a Racal Dana switch. The output of the switch went to a traceable frequency counter. My program logged the results and printed a report. Commodore PET, Basic and assembly, IEEE-488. As I remember it was testing the crystal oven output and not the finished device. There was a lot of hand labor that went into the final product. Assembly was by hand, of course. There was a lot of technician time in testing, tweaking and troubleshooting to get them in spec.

If you search this thread for FRK you will find more information. I have a number of FRKs and recently pulled one out of storage, fixed an intermittent fault and am boxing it up. Mainly as a frequency standard (I've several GPSDOs) but with a clock display (old HP amber dot LEDs) for fun.

Quote from: Andrew_Debbie on July 09, 2021, 09:00:16 amI quite enjoy bringing Tek 54x and 555's back to life. Rugley is just inside the reasonable distance from Anglesey. Not that I need it to get a 546 or 547 working. A few problems remain:Tunnel DiodesNot enough space on my workbenchOne hernia is enough, thank youI would need to buy a bigger house. Debbie would leave meSomeone has bid on them. Anyone here?As near as I can tell the tunnel diodes in the A & B Trigger are apparently OK. Same with HV transformer. Obviously I can better confirm this once I get the vertical and sweep fully operational.Bench 2 can barely accommodate and I have to remove most of the other equipment.Agreed. One hernia is one too many.Yes, for all practical purposes I am out of room. But by impractical means I have plenty of room. Jo Ann does not live here and has no say in the matter but she does think I'm nuts. And this morning it tried different tactics. I won't work. But damn she is cute and she's got the batshit look.

Bored here. Nothing to buy on ebay. Considering building a silent Linux PC for VM host because I'm bored. Insanity or not?

All back together now, and I am very impressed with it, makes stripping a board a trivial and easy task.
<snip>My latest acquisition is a Duratool desoldering pump, ebay ofc, which I managed to bag for £51 shipped. Finally picked it up from the sorting office today, after a bit over a week (work hours and sorting office hours are not a good match atm).It was a definite and immediate candidate for "don't turn it on, take it apart", as there was the sound of small metal parts rattling around, and also the thump of large internal components doing the same.Opened it up to discover the pump and power supply (contained within its own aluminium case) flopping around tethered by their wires and tubes. The small parts were the flange nuts for mounting the rubber frame of the pump.No screws to be found anywhere, so can't blame RM for this, it's clearly the dumbass former user's fault.Fortunately, like all of us here I have a significant collection of useful orphaned hardware, and soon found a sufficient number of flange head M4 screws of the correct lengths, and the shake-proof washers for them.All back together now, and I am very impressed with it, makes stripping a board a trivial and easy task.[/color][/size][/b]
I have the very same model and I love it, as you say, stripping a board is now dead easy, unless you need to change the nozzle size, which needs to done when its cold for obvious reasons, not sure about the price though, I think I only paid £10 more and mine was brand new. Did you get the 2 other nozzles, spare filter pads and the 3 ram rods with it as well?@bd, you really should get one of these.

Wow, my car paint has been delivered, tested it already, good colour match. Now to remove the old trim, insert the replacement, mask the roof and windows and spray it, what could go wrong I wonder, rain??
