Went to an actual Bricks and Mortar store and brought two IEC leads  :o

Time to trawl the op and junk shops as my Milk Crate of leads only had 2 and 3m ones left ..... that and I am a lazy bastard and couldn't be bothered cutting them down and fitting new plugs.

I just bought $100 worth of 5% SMD 0805 capacitors, ranging from 10pf to 2200pf (all C0G), plus some bigger ones, and a few 2% SMT inductors between 100nF and 1nF.  I was getting tired of not having the right parts when building RF circuits.  I already have a large random assortment, but the gaps and various sizes were frustrating.  I also picked up 100ea of some various opamps.  I only *needed* a few, but the qty discount was hard to pass up.  Besides, you never know...

I used Digikey.  These components could have been cheaper, but I wanted the good tolerances that I could trust.  IMO, still a bargain.

   Got a Metcal SP200 for cheap.  Wanted one for years. Real nice bit of kit and the tips it came with are still up to the task. Though will also invest in some chisel tips.

Happiness is a Metcal. :-+ :-+

A beautiful set of Probemaster DMM probes all the way from the U,S and A to here in Belgium. 30€ delivered. Postage was over a third of that, but definitely worth it for me. The contact resistance between the two probes doesn't even register on my DMM, the ones they are replacing would read 50+ mohms! Short leads so as to not clutter my bench. Very happy with my purchase!

Good investment.

I set up my first big SMD collection from Digikey 15+ years ago, with 0402 and 0603 in E96 resistors, E24 MLCC caps and E12 MLCC inductors. About eight or ten years ago, I added E12 wirewound RF inductors in 0402, 0603 and 0805, size depending on which of them had a reasonable Q.

I also have a fair number of SMD power inductors collected over the years, including a few full series in E6. The problem with lab kits for power inductors is that they’re not really quite jelly bean enough to warrant stocking the plethora of specifications: you’re fighting a losing battle trying to always have all the right ones in stock.

I still use them very regularly, and have yet to run out of a value, but I do tend to keep reels of the very common values.

I don't do power work, just RF, so I have a good assortment of iron powder and ferrite toroid cores, so when I'm playing around I can wind the oddball inductors as needed.

I don't know if that's better or worse...  :-DD

Keeping it on-topic:



Lenovo e550 15.6" i7-5500U 2.40GHz 8GB 256GB SSD -$220 Delivered


Upgrade for mom-in-law's ancient Win7/4GB HP. I know the SSD's a bit small, but the price was right and she's a desktop neat-freak anyhow, so will take some time for her to fill it up. Worst case, I can upgrade it to a larger one when she comes to visit.

It's been on my "must have" list for a long time, but it took some time to find one at the right price. Daves video and a recent MJLorton video re-kindled my interrest and I went looking again.

Another USB-WWAN (mini-PCIe) adapter from fleabay.  Cost about 5€, so no big risk.

I have a Huawei ME909s-120 3G/4G/LTE modem working fine on one (Ubuntu/Mint NetworkManager/ModemManager integration works perfectly out of the box!), but the USB-miniPCIe/WWAN adapter I have has an AMS1117 LDO (5V to 3.3V at max. 800mA) that gets hotter than I'd like, and there is no way to add heatsinking to it. I'm hoping the new one has a buck converter instead.  Can't see the text on the 6-pin chip, but the presence of an inductor (and some capacitors) indicates I can have hope.. although what you get off fleabay isn't always what's on the pictures.

I'd rather not have to make the adapter board myself: soldering the mini-PCIe connector is at the brittle edge of my current skill.  Otherwise it is very simple, just USB, a SIM card holder, mini-PCIe connector, and 5V to 3.3V regulation, and some supply bypass caps.

A few bits and bobs... A pair of NOS Intel P8291A GPIB ICs and a few Samsung 16x2 LCD displays.

It should yield interesting projects.

P8291A... Maybe add an AT90USB1287 in there and you can get a USB to GPIB adapter?

Yeah, that is my intention. Just for familiarity, I would go for a MSP430F6x or a TM4C129, though.

Two Trenz Gowin LittleBee 9k LUT FPGA boards. Bought them for extracting FTDI firmware for my own Gowin board, but since I decided to implement JTAG with MCU, I have no use of them anymore.



Bought for 29 Euros each plus FedEx extortion, looking for sale at $20 each, USA only, free shipping.
It is better if you use FT2232 for JTAG though as that means native Gowin tool support. Depending on your MCU you can put both it and the FPGA in a single JTAG chain, which would allow you to debug both chip using native tools (Gowin FPGA tool for that FPGA, OpenOCD for MCU.) There are extremely cheap USB 2.0 hub chips like SL2.1A out there for combining FT2232 and MCU USB into one port.

Do you mind providing me a copy of that FTDI firmware? I would like to build my own Gowin board too and that would be very helpful.
