Today received a like new HP48GX calculator with its serial communication kit and user manuals.

Ordered a Zoyi ZT-MD2 LCR tweezers, and you, what lab gadgets did you ordered these days?

I need to be able to script my AVHzY CT-3 usb power meter to automate unit and functional tests. Started decoding the com protocol. I'm able to read Voltage, Current, Power, D+/D- voltages. Still need to decode the negociated PD objects and get all other informations from it.

Who remember this book? 😉

I’m evaluating GTD and task management apps for daily organization. Todoist seems like a solid option, but I’m not fully convinced yet.
Which tool do you rely on to stay productive?

I don’t want to be harsh on Espressif, but their tools packaging is a mess.
I’ve lived and breathed C/C++ (CMake, etc.) for 15+ years, and I’ve rarely felt so disarmed, frustrated, and disappointed as I do fighting with their toolchain.

working on a modest ANSI C compiler in my spare time. I would like to target microcontrollers. I'm up at IR code generation. While generating IR code is somewhat easy, I'm looking at ideas on how to annotate my IR to make code generation easier for banked arch like PIC18F/16F

What C compiler do you use for Microchip
PIC18F and PIC16F 8bit microcontrollers? @microchip-makes.bsky.social

A friend is offering to sell me an Agilent 34450A DMM for €300. Is this a good deal? Anyone here has experience with the 34450A or thoughts on whether I should go for it? or should I go for an HP 34401A (for almost same price)🤔 #DIY #Electronics

Amazing, how can they sell a 20.000 counts multimeter for as low as 21€ ??? 20 years ago such device would have costed 2000€

Acquired an Owon XDM1241. How the hell can they sell a 110€ multimeter with crappy probes? I even tried to clean them to make sure there is no residues of chemicals. How can you sell such a good measurement tool with so bad probes

Got a damaged Brymen BM231 multimeter. In voltemeter, it seems to read DC voltage correctly, but in ohm-meter, it shows erratic behaviour, sometimes 0L, sometimes 0MOhm, sometimes display flickers.
Do you know how can I explore and try to find the origin of the problem?

If you are courageous 😋 there is also a preversion of LLVM port (with partial C++ support)

and (my beloved language) a Pascal compiler (and IDE) too 😅

for flashing, you can emulate a 27xxx EEprom via a simple STM32 or RP2040 or ESP32 to speedup process, or you can use flash memories pin to pin compatible with 27xx and progammable via TL866II Plus programmer

You can also use the port of VBCC compiler that have the 6502 backend now sun.hasenbraten.de/vbcc/

for flashing I use TL866II Plus programmer,

I'm considering resurrecting my old custom 6502 CPU board. What's the best toolchain these days for assembly, perhaps C development, flashing, EPROM emulation, maybe even debugging?

Keep it alive, you can eat it later, it's a good protein reserve 😂

Finished printing 4 units

making kitchen cabinet plinth clamps. I'll print them in PETG and check if it works
