There are plenty of displays and devices with this kind of display available for sale, so you can find a suitable one. But it matters to me because I don’t like “hacky” solutions. IMHO, having a radio module inside a precision instrument isn’t the best idea.

Yes for now it is only going to USB and ethernet on the back side of the k2001. Will be a long term project but the replacement display's are rare (K7001 comes to mind but they ask even $200 for them) and you dont know if the display is worn out.

Bought an Adret 7200A generator with option 06
10Hz to 1.3GHz, I've always wanted to have one. It will stay alongside my 103A and 7100D.
I traded it for a bunch of other instruments.

Unfortunately it doesn't boot, seems to be the main voltage sector filter, smells like RIFA caps haha!
It's a rare unit!

Bought a HP Prime G2 calculator. Still got an TI Nspire CAS (version 1) and an old TI 85 but can get along with the trackpad/pointer on the Nspire and the battery runs down with the calculator turned off. Thought I'd try the HP as it should be faster and have better battery life and I read the PPL programming is better. I'm mainly interested in the python capability as well. Thanks.

@Zoli 3D printed "Save" symbols?

bought a Marconi Adret 4101A 15-200 kHz frequency standard receiver at a ham rally.

Essentially an OCXO dsciplined against a VLF time standard transmitter. Had to clean out the old NiCd batteries that had long ago dumped their electrolyte on the mainboard but for the rest it is very clean for a 1990 unit. I am using it with DCF77 at 77.5 kHz for now, as it came with a nice Meinberg DCF77 outdoor antenna,

*** Please PM me if you happen to have docs on this model, sofar I only found a spec sheet by Adret.

I wish to have a printer which prints plastic, brass, aluminum and steel in the same work piece...

I spent about £500 on a suit and nice shoes.  It's something that I've needed for some time and certain personal events necessitate it... I am not much of a "formalwear" guy but I can see how it can make things better sometimes.  The question is... will it get any use outside of weddings and funerals?  I guess I might wear it to a job interview, but I'm not planning to interview any time soon.

Those Japanese electronic dictionaries I ordered came in.

Unbelievable LCD on that Seiko to the right, it is biased/tuned(?) to be extremely reflective for light sources above it, I've never seen one like it, you can see it compared to a standard LCD on the left. There is no backlight that's just the ambient lighting! I swear it's brighter and has better contrast than the modern e-ink display on my Kobo ereader.

I now understand why there are Seiko dictionary "fanboys", their keyboards are a lot better it has chiclet style keys like on a laptop. Oh man I'm gonna have to collect their whole range aren't I....(with parts spares too haha)

On the more modern Casio/Sharp they use this weird diving board mechanism so you have to press on the bottom of the key, really annoying lol. Unlike the Seiko you have to whip out the stylus or use the touch screen to highlight a word to do a quick jump lookup, the Seiko has a "jump" key that reveals a cursor so you can just use the fantastic keyboard to navigate.

I went to Digit in Osaka and bought those:

- LM3999Z (didn't know it exists), 4euro/piece. It's a small cousin of LM399 https://www.eevblog.com/forum/metrology/lm3999/
- LM320 in metal can (negative regulator)
- LM336 (shunt voltage reference)
- TL431C clone from "HTC Korea"
- TL2426 (rail splitter)
- 2N5089 (super-beta npn)
- J111 (jfet, but with "large" current)
- a bunch of less rare jfets, mosfets and transistors, a few leds, a neon lamp, and a small incandescent lamp.

Just picked up a Tek DPO4104, Ch2 and Ch3 fail self-test and just output garbage waveforms. Sounds like dead ADC or the typical BGA solder fatigue. Still not a bad deal to use as a 2-channel scope.

To good to be true turned out to be true! They had it listed at $250 and had zero history buying or selling on ebay. Offered it to me less after i said its an obvious scam and after they changed the listing to $500(after a few back and forth messages). So being purchases are generally protected i purchased it. Only gripe it was shipped in its factory foam i think and was kinda loose but it survived. I honestly thought the box (iv gotten a letter as a package scam before) was gonna be empty.

I found this while thrifting today: An HP-35 in really nice condition, with original AC power adapter. Pictured showing Pi/1000 just to light up some digits. Seems to work perfectly; keys have that beautiful distinct HP calculator clicky feeling, not sticky at all. I am not a collector, but I couldn't pass it up, especially as I paid only $5.99 Canuck bucks. I think it's worth something quite more than that. I love the bubble LED display, but a one-line display for a RPN calculator with a stack is cumbersome to say the least.

Today I received my YH.801 capacitor discharger and the FNIRSI C2.

I'm not fully satisfied with the C2 though. Unlike the FNIRSI C1, which I've been using on my bench for quite some time, the C2 no longer includes Bluetooth support.

The C2 definitely has some advantages:

* slightly larger display
* support for more charging protocols
* useful USB cable detection

However, for my particular use case, the missing Bluetooth functionality is a major downside.

When testing and repairing devices, I often use OBS with an instrument overlay for screenshots and documentation. I had Claude Code create a custom overlay for me.
Most of my instruments are connected via LAN, while the FNIRSI C1 sends its measurements over Bluetooth.
That setup allows me to display all important values directly on screen and document everything properly. That's exactly why the BT feature was so useful to me.

I don't understand why FNIRSI decided to remove Bluetooth support from the C2.

That is what i call a proper instrument. I've got a couple which i am going to take to my grave with me.

Bought a couple of Wera sets:

I upgraded my HP/Agilent/Symmetricom GPSDO 58503B without Clock Display in early 2024,
with the Synergy SSR GPS Receiver Replacement (uses newer uBlox GPS receiver with Oncore conversion).
https://synergy-gps.com/synergy-products/ssr-series-ut-vp-single-board-replacement/

I had sent my 58503B to Art Sepin at Synergy to assure all the Symmetricom and Oncore receiver messages
were being properly captured and interpreted/converted by the new SSR GPS Receiver board.

Rock Solid operation for over two years with no Week Rollover issues.

• Designed for Navigation and timing applications
• Motorola binary message emulation at 9600 baud for backward compatibility
with legacy Motorola 6 and 8 channel VP and 8 channel UT+ and GT+ receivers.
• 12 channels included for updated UT+ legacy products
• Super-Fast TTFF and State-of-the-Art Sensitivity
• More satellites tracked than receivers being replaced
• Better ADEV performance in legacy timing instruments
• Drop-In to most VP, GT+ and UT+ GPS receiver slots Without the need for user intervention
• *No Receiver 1024 Week Roll-Overs!

I bought the Peak Atlas DCA75Pro from Digikey.

[exe]

Two resistors from @derZockerMP, 10 ohm and 10K. The latter came with a temperature sweep data showing average tempco 0.24ppm/K in range 18..28C (measured at 18, 23 and 28C). Can't wait to measure them with my DMM7510.

[gamalot]

Pulled the trigger on a Siglent SDG1022X Plus on Taobao, all in with shipping, payment charges, and GST it was around AUD 480.

Did not buy but found on the city's lawn, a 10 A/h power bank. Tested and measured 9.5 A/h capacity 

[apetersw]

After finally getting fed up with the finicky Hti-301 Thermal Imager and its accompanying crummy software I got a Guide E4S as a replacement.

Bit expensive, but otherwise a nice, robust instrument that just works out of the box.

Hi, I am looking for a thermal camera for PCB debugging and design. Did u buy the macro lense with the E4S? And how about not having a manual focus.
Mind sharing your experience with this device?

Got myself an RXN-303D power supply, gonna run some tests on it soon.
