Metcal MX500 for £160. Two years old from a reputable seller. I don't need it but it's too tempting as an affordable way to experiment with induction heating

I'm wondering now whether the Hakko FX-1002 micro iron is compatible with the MX500? I know that the FX-1001 is so I'm hopeful.

Something I DIDN'T buy today was a new thermal imager/camera/sensor. I have one from Seek Thermal that plugs into a cellphone/tablet USB2 connector but those are few and far between on today's cellphones, and Seek's app has stopped being compatible with my tablet.  :wtf:

I need to do a thermal study on a power circuit I'm working on and was going to post here for recommendations on an inexpensive camera, when I remembered that my wife had saved one of older Motorola cellphones. First thing this morning I grabbed it, downloaded the app, plugged in the sensor, and voila - I'm back in business.

Here's an annotated image looking at the breadboarded circuit with the 13A load running at 50% duty cycle (2 seconds on/off). A nice $0 solution thanks to my wonderful wife!  :-+   :clap:

That's why I avoided the phone linked thermal cameras, in case it was a brick after I upgraded my phone. I waited until there was an affordable stand-alone unit that fulfilled my needs. In my case it was a HTI HT-18 that I chose and I haven't looked back since. Really happy with the device still and still fulfills all my needs.

Yep, I can't argue, and my replacement plan was going to be a standalone unit for exactly those reasons. But I got this Seek Thermal unit on a whim, basically an impulse buy several years ago for under $200, and no standalone unit could match its resolution at anywhere near that price.

My plan now is to keep the old phone with the sensor as a system. The phone doesn't have a SIM card so the networks don't "know" about it. I'm keeping it in Airplane Mode so all of the wireless interfaces are disabled so, amongst other things, Google doesn't try to force an Android update on it. I pull the images using USB. It should be an isolated island and continue to operate for quite some time, so I'm back to having a reasonable thermal imaging system for the low incremental price of $0.  :-+

Stuck in the house for months.  I bought a big bucket of Church's chicken and a bag of Okra.  Yummm.  Best chicken on Earth ever!

For the E-Bike, get rid of bullet connectors and replace them with XT60 connectors, you can also get a three way XT60 connector for the motor drive.
The bullet connectors are crap as is the wiring sheath, when they get hot due to contact resistance they wreck themselves and the insulation on the wiring.
Not easy, not hard, just need to be incentivised.

I bought a Hewlett Packard HP9100A
I actually bought it... I bought my holy grail!  ;D

Sure, it's broken, but I could actually afford this unit, and that's what matters here. I routinely see these sell between $3000-$5000 when in working condition. When broken, I've seen these sell anywhere between $800-$2000. I actually got this for the lowest price I've seen in the past 11 years, and belive me... I've been watching every sale between then and now that I've spotted online! I can always gradually work my way through all the resistors and diodes, testing for failed components. Maybe I'll even get it running someday.

This is purely an acquisition of desire, not need. I've wanted one of these for a quarter of my life, and now I have this piece of engineering beauty! Sure, I could have bought a new CPU and motherboard for what I spent, but I think I'll be happy to have this beauty from 1968. Pics are the seller's pics... I've bought and paid for it, now to hope the UPS guy doesn't abuse it!

this wiring is only temporary.

Two MSOX3054T, four 15A 100MHz current clamps, four 7kV differential probes and four 800V differential probes.
As usual with me, Keysight just had to ship something DOA, and this time one of the eight passive probes came free with the scopes is dead.
Also the ordered APPBNDL licenses were incorrectly placed and I got BDLA, which lacks AWG.

What are the model numbers you got?

Correction, the 300M probes are 300V.

They are N2893A (15A), N2804A (300V) and N2891A (7kv).

Rebadged Testec TT-SI 9010, unless in turn they are getting it from someone else, not bad for general use although not good to measure floating Vgs or anything with fast changing common mode as distortion and ringing is clearly visible.

Forget about Vgs. Its noise floor is horrible.
For Vgs, we have a pair of Tek fiber probe (costs $-5 digit each) and a CleverScope. For low voltage applications, a carefully calibrated (for common mode rejection gain) Analog Discovery is better.

An early birthday present: a Rigol DS1054Z. With the Tequipment discount plus their NOTAX coupon code it came out to $329 shipped. This replaces my Tek 2235 which still worked great but had too many limitations (no single shot acquisition and size being the big ones). And yes, I've already hacked it to 100MHz (it already came with all other options enabled and the latest firmware).

I came across an e**y-offer offering 200pcs unused  test probes.
For EUR 15,46 shipped I couldn't say no. Was too weak.   :-DD

A -hp- (Harrison) 6206B. In a very sorry state. It ended up being free, because GSP and USPS took turns in breaking it. Ebay handled the refund excellently.

Oof.. That looks terrible, although it seems the package had at least some padding as the knobs and the posts look somewhat intact.

Just got that AMIQ. Now to get it working!

On power up it emitted a series of beeps that was very familiar. On opening it up I realised it is the BIOS beeps for a malfunctioning graphics card.
Of course it does not normally use one. I plugged an old ATI card and could see the boot up procedure with Caldera OpenDOS 7.01 and a notice about "not for commercial use" or such.... :-//

Next thing to do is image the hard drive and locate user and service information to use the GPIB and talk to the unit. If I get it working I'll start hunting for a SMIQ 03 to pair with it for I/Q modulation.

REPAIR, RENEW, REUSE, RECYCLE, REBUILD, REDUCE, RECOVER, REPURPOSE, RESTORE....

Somewhat, yes.

The mains switch is a goner, needs a new one. (funny enough, the schematic I've got does not show it being a 2-pole switch, so I'm having to trace out and replace accordingly)

The Volts pot seems OK. Not been able to test yet.

The Range / Metering switch is compromised. It's been kicked in, and the switch wafer assembly has separated from the bushing that holds it in the chassis. Needs out-of-chassis repair. Supposedly unobtainium since it's concentric and all. I have hope it will be repairable.

The meter came back in place with some persuasion, and the movement is OK. It gives a reading if I probe it with a multimeter in Ohms mode, and the multimeter reads the coil as some 100Ω.

Hakko FM-204 desolder gun for the bench. Not desperately needed, as I don't deal with that many TH parts, but when I do they're often connected to power planes, and really need some work to remove... Thinking I might buy a regular iron to plug into the desktop box, too. Occasionally a 2nd soldering iron is useful, and If I'm going to have that box sitting there anyway.....

Lenovo P53 laptop (plus two TB3 docking stations) to replace my old W540 (and its docking stations) that's starting to bluescreen a bit more often than I'd like.

I bought a new desoldering station to replace my old doss that went poopy in its trousers.

I’d love a Hakko FR-301 but they are monstrously overpriced here in Straya!
