A pair of IRFB4227's and an IRS2110 driver chip, careless stupidity on my part spectacularly (loud bang) blew up the half bridge stage in a DIY SMPS based thingy! I hope I have figured out how I did it, slapped my own wrists

A bunch of these incandescent 7 segment displays, to finish my minitron-clock, and synchro differentials for experimenting.
A already received 6 of the displays a few weeks ago, one was bad (lower intensity and higher current than the others, maybe due to internal gas residues), and I broke one while starting to build the clock, so I ordered some more.

For some reason I forgot to upload an image of the board for the meter.

Nice. Can you erase them with a strong neodymium magnet?

Picked up a couple of 'some assembly required' units.

First is an HP 6002A power supply.  50V, 10A, 200W with GPIB.  No output.  $40 plus shipping.

But wait!  When I look at the back.......

Those two grey switches on the right.  Not sure about the one on the right, but the one on the left sure looks like it's pushed in.  No!  Seriously?

Second unit is an HP 5065A Rubidium Standard.  Top & bottom covers missing.  Some companies do this to 'destroy' equipment before they dispose of it.     Boo!  Hiss!     Kill all the lawyers - and bean counters!!   

In the world of Rb Standards, these things are the gold standard.  A few weeks ago, one sold untested for $1500.  I got this one for $123.    

Lots of fun coming up!

Well, that was wasn't nearly as much fun as I expected!

I repaired the power supply by plugging in the internal connector that came loose.   

I repaired the Rb Standard by cleaning up the carnage from 5 or 6 leaky Tantalum capacitors and undoing the damage caused by the previous tech.

Ferroelectric!=ferromagnetic

+1 , simply put, FRAM is not affected by magnetic fields.

Nice! I was wondering if someone here snagged that one. Now, you just need to find a replacement logo.

[cdev]

Wow, that looks very cool. And you know its good quality if the Swiss post office used it.

>A elecrical motor scooter from the local post office, they are cheap because the manufacturer is defunct. I got a nice pile of extra components and documentation for the thing.

> There are four 100Ah lifepo4 Batteries inside, it can drive about 80km with one charge. Now i have some reverse engineering to do. It uses CAN or RS485 between all components.



I would be interested in hearing more. Ive seen a similar electric scooter used by a coworker in a daily commute that involved an approximately 2000 foot climb in elevation at a previous job.

That's cool stuff, but don't forget about the FG502 you're working on. Don't get too distracted!

[Johnny10]

That is funny !

I was just thinking that this morning.
I have too many projects started and ongoing.
Datron 4000A ( Repair DC Current Board)
Vision Engineering TS-3 Microscope (CCD Camera Setup)
FG502( Order Parts )

Tektronix 4041 ( Do I really want to program GPIB in Basic?)
Tektronix PG506 (repair front panel)

McIntosh MC2105 (repair left Channel driver board)

 

[boffin]

well, I figure if I'm going to fiddle with some SMD, I really should buy myself one of these:

Was pretty reasonable on Amazon.ca (C$65) . although I see there are a lot of fake sellers selling them today

Last year in August I've bought this:

AOYUE Int852

I am very satisfied with it's performance.

This took 3 years to find. A General Radio 900-TUA tuner. Sister unit to a 900-TUB and 900-LB slotted line I have.
It's on its way, still has some international hurdles to pass. Hope I didn't jinx things by mentioning it before holding it in my hands.

Looks like it's missing the paper manual, so that's one more hunting item.

It's being shipped to me, but I just bought a B&K Precision 1511 power supply for super cheap.   

Sadly, I didn't pay attention to the specs - only 10mA max output on the high voltage side, which limits its usefulness. At least the low voltage portion has decent power.

0-20VDC, 5A 0-80VDC, 10mA 0-500VDC, 10mA
AC 1.1V, 2.2V, 3.3V, 4.4V, 5.5V, 6.6V 2A

Aneng AN8002 multimeter for 12.16€ shipped from Banggood.
I'm going to add Range and REL buttons and an optocoupled USB port for logging (CP2102 board for converting UART TX to micro USB).

[canibalimao]

I was planning to buy one of those but I didn't know if they were worth buying. Can you please do a very quick review?

I just read the manual on this item.

Simple and to the point!

Operation:
Plug model 1511 into AC outlet. Turn power switch on.  Select desired voltage, use
control knobs to adjust output.
