Der Elko dieses LED-Netzteils ist sichtbar aufgebläht und führt zum Ausfall der Lampe. Der Austausch mit dem Lötkolben ist schnell erledigt.
The electrolytic capacitor of this LED lamp power supply unit is visibly blown and causes the lamp to fail. It can be replaced quickly with a soldering iron.

"This synthesizer is the world's first programmable music synthesizer. The first piece of electronic music to win the Pulitzer Prize was made on it. Basically a two voice synthesizer with tone generation and composing in the left hand side and processing on the right hand side, including manual binary for the ordering of the effects processes. Which, for its time, essentially like a Turing computer, was one and a half tons, seven feet tall, 14 feet wide — it's quite a behemoth, but now it's a very large paperweight."
—Seth Cluett, Director, Computer Music Center and Lecturer in Computer Music & Sound Studies at Columbia University

Hello and welcome to this week's installment of #nakeddiefriday !
The guest of today is the TIBPAL16R4 by TI, a programmable array logic chip made with bipolar logic. The die has 2 metal layers, its maskwork produced in 1985. A short thread follows.

1/2 Hello everyone!
I've been working on a major #electronics project for some time now, and I've finally gotten around to announcing it here.
So basically I'm working on an alarm clock type desktop companion thingy that can sync time over NTP, display the weather, maybe have some side 'pods' to hold stuff, also have a few USB ports so that I can charge multiple devices at once with less clutter, and more.
I'm still in the parts choosing phase rn, but I'll post updates every few days.
So when you have a bunch of jellybean JFETs (2N5457), time to burn, and a handful of 1uF bipolar capacitors…
What to do.. 
I decided to build a simple amplifier 
Although many find JFETs aren’t quite as intuitive as a regular BJTs, they’re not THAT scary 
and they’re easily biased, using a megaohm sized resistor from the gate to ground.
To be able to do some more accurate calculations, I decided to measure the maximum drain current, IDSS, and the negative Gate-Source cut-off (pinch off) voltage, as they can vary significantly even between devices even from the same batch.
A fun evening in the lab

Wooo, the new UFB input boards come in on Thursday/Friday. White PCB with black lettering...I'm so stoked. Once I get the assembled I can start working on the RGB code. #electronics #fightstick
According to a new survey, shoppers who are concerned about tariffs driving up the cost of tech products either planned to purchase ahead of tariffs or have purchased electronics late last year or early this year.

Special shoutout to the repair site iFixit who are now on the Fediverse, you can follow them at:
They provide repair forums and free repair guides for phones, computers, consoles, kitchen equipment, tools, medical devices, cars etc. They also review and tear down new gadgets to see how repairable they are.
Repairing your existing stuff is much, much better for the environment than buying replacements.
Finally added a proper license to the fightstick project. Honestly, I'm stoked to get the last revision of the input board in from JLCPCB so I can make all of the RGB. #fightstick #electronics #programming
@trouble @ascentale @mossyfoot @bikenite I was asked what kind of battery. It's this one!
https://www.ebay.com/itm/186641137947
It's kind of a rare model but it is out there!
You'll need/want to take off the battery's included regulator circuit board; the MonkeyLight canister has its own. But that's easy, it's easy de-soldering.
I've updated the ottopot website and build instructions with the PCB version and the new case.
I'm considering this the v1 release 
The ottopot is a MIDI controller with 8 endless potentiometers sending 14bit CCs.
Special thanks to @Nervengift for the PCB contribution.

Glued and soldered everything together. Now it feels like a real device! I'm super happy! Thanks again to everyone who has helped me to get this far! <3
The CO2 Canary is open hardware, you can find all source files here:

I'm planning to write detailed instructions on how to order the required parts, so that you can get one yourself!
Yep, my mistake: I didn't number the pins of the chip correctly! SDA and SCL are pins 8 + 7, not 5 and 6! Not sure how I got that wrong, but it teaches me to double-check next time!
Luckily, the fuel gauge is the one component that's a bit optional – just nice to have!
Resoldering it on the board seems difficult, as it's so tiny! How would you approach that? I mean, I could try to cut the wrong traces, and solder teeny tiny wires to the chip? #electronics
My #Z80 machine is getting some new input devices.
Watch this space!
