UT622E LCR Meter
..
What I dont like about the UT622E so far:
- UNI-T Device Manager software requires a COM port below 10.
- Black GUI (but that's only me).
- 100 MegOhms max. Sometimes I need around 1 GigOhm.
I haven't Googled it yet, does it come with a RS232 port? if yes, is the communication protocol documented?
Test cables. I like the connectors on these obsolete series Megaphase cables. The new "equivalent" series has sucky connectors.
The UT622E has a virtual COM Port via USB.
Its the software supplied with the unit which has the <COM 10 limitation.
Communication (SCPI) is documented in the manual and works as advertised.
Tried it with Profilab. May eventually publish it on the abacom-online.de site

Shannon tweezers (https://www.eevblog.com/forum/testgear/design-a-new-precision-lcr-tweezers/ https://shannontweezers.top/)
I absolutely love how they effortlessly and consistently measure 1pF. I hope with these tweezers my small capacitors (0603 and 0402) will stop flying around . Also, interestingly, my cheap lcr tweezers are spot-on, though don't have as much resolution. But they are not of much use due flimsy tips not being able to grab small caps reliably.
After using ST3 tweezers for ~15 years ST42 tweezers do have a different feel where you need relearn how to handle SMD components.
FWIW practice, practice practice.
A Bus Pirate version 5 preview pcb.
I have one of the first Bus-Pirate versions, which I used a lot at the beginning to have something that spoke I2C, but I don't use it anymore.
Today I'm looking with great interest at the latest version bus-blaster, very unfortunate as a project because they haven't even dedicated a page, but it could be very useful as E-Jtag MIPS on MIPS32-r2 targets, like my Atlas eval board.
I still have to order one, and then... well, then I have to experiment for myself, because there's no one around who can give feedback
a Milwaukee battery - rather than a Makita one
So I can't be the only person suffering TEA issues,
So last weekend I spotted something I had been looking for so I put a comedy bid for one, then spotted a better one so put a comedy bid on that. So now I own two Current Clamp Meter attachments for a multimeter. A i410 and i1010. The i410 is rated for 400A AC/DC with a spec of 3.5% + 0.5A for DC and AC, whereas the i1010 is rated for 600A AC and 1000A DC but at a better 2.0% + 0.5A specification. Just need to keep an eye out for a low range one for those moments when I want to measure the resting current or at least know the leakage current on vehicles.
Found this almost featureless thing while thrifting, all it has in the rear is a round 4 pin power connector with no indication, a USB B socket, and a grille with a fan ...
Chunky + heavy + metal + 5$ = buy
It's pretty big and heavy, I thought maybe a USB chargeable battery back up. I figured I could use the aluminum case to maybe make something. (yeah right)
But noooo, inside it's two 500GB SATA WD hard drives hooked up as a 1TB drive. Of course with USB 2.0 it'll probably take 5 days to fill ...
Of course the power pinout is the reverse of the power supply I have so it'll have to wait.
Meh, so worst case 5$ for that enclosure is not bad.
Max speed for USB2.0 is 480Mbps, faster than the 100Mbps LAN.
Just placed an order for a Flipper Zero for $169:
https://shop.flipperzero.one/I noticed, though, that there are many Aliexpress listings selling them for twice that amount (but no listings on ebay).
Also, the Flipper website says demand for the units is very high. This makes me wonder about the Aliexpress listings. Are they a scam? Or perhaps they actually bought Flippers and are just flipping them?
I've been hunting for a decent LCR meter for my bench. I managed to score one
Finally the hunt is over!
Some more SMD binder component sleeves. Same dodgy seller has some used DMM's for auction too eBay auction: #225859761121
Dave is selling some old meters, has hell frozen over?

It was just flipping early on when the demand was high and there was huge hype. Its died off now. There will still always be some premium for aliexpress, since they will ship to some countries the official store does not. But let us know if you find some interesting feature.
Also arrived today a $9.34 AUD box for my FNB58 logger/tester and load to suit. Room in the lid for a short USB power and data lead too. Arrived with a few hundred assorted velcro cable ties to sort out some mess as well

Last of the seller's short Mega Phase cables (bought 2 previously). Also looked at his other items (on eBay) and got a 100 MHz oscillator.

after watching a Franlab video?
Today, the PPC archive version 2.44 arrived.

inspired? by the new 50 dollar multimeter robustness testing prospect I went for a Vici VC97A

What's your general impression? Any good?

All three are good things? The FNB58 PC software seems better than the average Chinese offerings and overall the unit does what it says on the packet.
The Box other than taking a sledge hammer to it will surrive any general abuse or Mr Bozo moments.

Stefan Gotteswinter who 'made me' push the button on one with his latest video
Really good deal on a drill sharpener in Oz at present if anyone is in the market for one. It might seem like a lot but I will get back a very large chunk of it with 'the box' of drills of mine and my Dads ancient ones. It is missing the web thinning part of Stefans good one but on smaller drills not the end of the world in particular if you pilot bore the larger ones.
