Aren't there extension cables for these solar panel connectors? I only find "MC4" cables, which seem to be only the connector on the receiving end but not the panell side. I need an extension for the panel side though. as 2 of the 4 panels are further away.
Do those extension cables even exist, or isn't this meant to be due to some frequency issues? Should I instead get another one of those cables with 4 connectors put them in a row if possible? (Seems to be possible?)

Final version of the UFB input board with the added RGB/SPI support. Broke out a new header with some of the pins which should make things easier to expand. #electronics #fightstick
I'm not entirely surprised—I’ve noticed that old digital watches tend to run faster over time. I have a few vintage models from the '70s and '80s that have noticeably picked up speed with age. I always assumed this was due to the natural aging of quartz crystal oscillators, but perhaps there’s more to it than that. Could there be another factor at play?

So, how much should I be spending on a logic analyser to look at, say, a weird PS/2 mouse's protocol, or some other vintage PC or console controller oddity? AU$8 from AliExpress? $120 on an ES-DLA-16 from Mouser? Surely I don't need an $800 Saleae box for that?
My hobby-focus seems to be swinging back to #Arduino and #Electronics stuff at the moment and I want to take full advantage of it to learn some very niche new things.
Boosts appreciated. #AskFedi
In this week's video, I take a dive into some electronics as I build a VU meter for my Eyetech A1200 tower. Watch here and enjoy: https://www.youtube.com/watch?v=vuk6dGTq280&list=PLTfPIrcIusflyvR6J1HP6-mUlHWg9_vhy&index=8
Happy with the look! 
For the "standard" assembly process, they add these little rails on the sides, which you can then break off.
This is the first time I've designed my own PCB! Now I'm really excited to see whether they'll work! :O
My latest blog post: VanSpoof – A-Muntzing We Will Go
https://mikecoats.com/van-spoof-muntzing/
With my first few VanSpoof prototypes assembled, I had noticed that the L78L05 was sometimes getting a little hot. Instead of knuckling down and calculating more suitable component values, I turned to the tried and tested method of Muntzing to get my power draw down.
Okay, I think this is the final update for the input board. Rearranged the SPI1 header pins and cleaned up the labeling a bit. Gonna wait for the v1.1 boards to come in and verify that they work before sending this out. #electronics #fightstick

I combined dicewords with PasswordMaker on this @adafruit PyPortal in order to generate random site-domain specific passwords. The Circuit Python script will regenerate the password provided I can remember those 6 randomly selected words. It also acts as a keyboard HID

Today's electronics project: added fan grilles to one of my PC fan Corsi Rosenthal boxes, because my (adult) son stuck his fingers in a fan this week 
(no injuries) The grilles are almost as expensive as the fans. Next time I will mske them RGB fans so there is no question the fans are ON. #electronics #diy
Digging through an old box and found these from back when I'd get any new microcontroller... sigh. Anyone have a use for them?

Looks like there will be one more revision for the input board. I want to add an SPI header to it so I can add RGB LEDs to the buttons and such. Shouldn't be an issue as `SPI1` is only used by the SD card on boot which frees it up for RGB operations. I also ordered an RGB button kit from Paradise Arcade for some testing as well. #electronics #fightstick
The latest release of the #AirGradient firmware removed the code that phones home to the company servers even when you check the to to explicitly tell it not to do so. This is a big win for #privacy and #SelfHosting!

I plan on flashing this onto my device and testing it to verify nothing was missed. #tcpdump and #wireshark are my friends. 
Today was one of those physics lessons which completely escalated in a fun and spontaneous way when students demanded (at the end of a long arduous unit on induction and electric/magnetic fields) that they want to 'transmit something'
So I took our pedagogical electronics system and let them slam together a meissner oscillator from the students manual, and pimped it to run at 400k instead of 400 ;).
Whatever leaked from that to my SDR we put on the big screen. Supply voltage was modulated by an audio amp in series and voila ;-) a lot of fun was had
Let me emphasize for legal reasons that this is not a transmitter. It is an oscillator whose electric field can be picked up a few meters away.
Audio heard is the received signal decoded in the Airspy software.
My latest blog post: Simplify VCD
https://mikecoats.com/simplify-vcd/
Simplify VCD is a tool designed to make working with Value Change Dump (VCD) files more efficient and faster. This tool enables users to clip sections of VCD files, trim irrelevant data, and reduce the resolution to a more manageable timescale, significantly improving processing speed and usability.
