A half built DIY joystick on my workbench with the red lower shell and the top black shell separated and the wiring showing.

Closeup photo of an Amiga 3000T mainboard. The 68882 coprocessor is removed and there are some areas where the solder mask and corrosion have been removed.
The #Amiga3000T restoration continues. Successfully pulled the 68882 FPU and cleaned up the corrosion underneath. Still some traces to fix and vias to bridge but I have high hopes that it’s going to boot at some point. #InTheLabDoingStuff

2 Nintendo Super Famicom controllers taken apart and the mechanical parts spread out on a towel for drying after washing them in soapy water.
The Mitsumi circuit boards from the two controllers on my workbench, cleaned with alcohol and contact cleaner. Q-tips, tissues, IPA and contact cleaner are sitting next to the PCBs.

Turned out to be one of the (kind of rare) cases where it actually sounds significantly clearer and more powerful after replacing the caps and adjusting it correctly! Nice. #NAD7020e #InTheLabDoingStuff

A NAD 7020e receiver with the case removed on my workbench. Several tools and a pile of old capacitors are scattered across the desk. My multimeter is connected to some test points on the circuit board and showing the idling current.
Recapped and readjusted the #NAD7020e today. Meditation Beta style. #InTheLabDoingStuff

My Amiga 600 on the workbench with an external Gotek connected.
Amiga workbench screen running the Amiga OS 3.2 installer in the process of installing the German locale disk.
Did some Amiga 600 updates and upgrades today and made it run more stable again (I hope). #InTheLabDoingStuff

My ageing OSSC (Version 1.6) on my workbench with the top case removed before modding it.
Closeup of my OSSC‘s circuit board with a tiny wire connected to one of the surface mounted chips.
The other end of the wire connected to where resistor R35 used to be (I removed it beforehand).
My OSSC‘s screen is happily reporting the latest firmware version 1.12 after all the modding and flashing.
Didn’t get much else done today, but I successfully modded and updated my (outdated) #OSSC. #InTheLabDoingStuff

A VIC-20CR board on my workbench with the Dead Test from the Penultimate cartridge running on the screen that is connected. My multimeter and several tools and bits are scattered across the desk. Dead Test passed all the tests, it seems!
VIC-20 repair going on in the lab tonight. #InTheLabDoingStuff

The innards of a beefy PA power amp (HH Electronic MX 900) on my workbench with a huge toroidal transformer, some other circuitry and 16 TO-3 transistors in the power amp section visible.
My main repair project for today was my bicycle (the rear tire recently disintegrated completely, replaced it with a new one now). Next electronics project is this HH Electronic (now HH Audio) power amplifier from the mid 1990s. It’s likely still okay, just an inspection & clean. #InTheLabDoingStuff

Amiga 500 Revision 5 Board on my workbench. There are labels on some of the custom ICs with the pinout printed on them. An entire row of RAM is socketed and some of the logic ICs in the data path also got socketed and replaced.
Current status: having my butt kicked by this green screen #Amiga500 board. #InTheLabDoingStuff #Amiga #Commodore #RetroComputing #VintageComputing #Repair

Commodore 64 Board on my workbench. It has some of the main ICs missing and several things look like previous repair attempts have been made.
Another #Commodore64 board appeared on the workbench. Quite a few obvious faults (apart from the missing chips). I’ll see what I can do. 😅 #InTheLabDoingStuff

Parts for the Open Source Arcade Stick spread out on my workbench. The case parts are 3d printed, there are some buttons and microswitches, a PCB for auto fire and various small bits and pieces.
I‘m going to build an open source joystick today. Pretty excited about this project, the website for it is here: www.osa-stick.com #InTheLabDoingStuff #RetroGaming #OSAStick

Working on a replacement timer for my EPROM ERASER. Uses a TM1637 LED display, a little piezo buzzer for audible feedback, a 5V relay to switch the ERASER and a rotary encoder to set the countdown. The code needs a lot of optimizations but I'm happy so far. #InTheLabDoingStuff youtu.be/YX8TaoQqPpc

My Commodore 16 on my desk with a wavy menu showing on the connected screen that lists some software accessible from the C264 Magic Cart that is plugged into the cartridge port.
I built a C264 Magic Cart (which is a Magic Desk style cartridge for the C16/116/Plus4 which can access up to 2MB of software from EPROMs). It’s very cool indeed!

My cheap EPROM eraser on my workbench with the lid removed. A new power switch was added and the mechanical timer was removed. A cordless drill with a step drill bit is sitting next to it on the desk.
Spontaneously decided to rip apart my shoddy EPROM eraser today and modify it a bit (the timer stopped working ages ago so I removed it completely for now). #InTheLabDoingStuff

My ZD-915 desoldering station with the lid open and my multimeter connected to the pump motor contacts on my workbench. A C64 PCB is visible in the background and several tools are scattered around (as usual).
Fixed the pump in my desolder station. Thankfully nothing major. Video coming soon! #InTheLabDoingStuff

4 ICs on my workbench photographed at an angle. The chips are (from top to bottom) a C16 PLA, a C16 KERNAL ROM, an 8501R1 processor and an 8360R2 TED chip from a Commodore 16.

This is to trigger the air pump. In the original setup, the pump is powered through the micro switch in the gun part (long thin wiring), now the gun's micro switch just triggers the relay and the power is coming directly from the DC-DC converter. #InTheLabDoingStuff

A cube-shaped automotive relay screwed to the insides of the ZD-915‘s front panel assembly at an angle. Connections are made with crimped spade connectors.
I hacked an automotive relay into my ZD-915 desoldering station. (Don’t worry, it’s going to be properly insulated with heat shrink tubing after the testing stage!) #InTheLabDoingStuff

My workbench with some 40 pin DIP sockets stacked on top of each other with four wires and a DPDT switch connected to them. A pair of pliers, tweezers and some solder are sitting on the bench. There’s a piece of paper with a wiring diagram for the switch on the bench, too.

A purple RGBtoHDMI PCB in my hand with super small surface mount components that I soldered myself. My regular soldering iron (that I used) is visible in the background in its stand.
I soldered some really smol things for the first time in my life! #InTheLabDoingStuff #RGBtoHDMI #Amiga #SMD

Digital microscope with a little flat screen on my bench. A small PCB sits under it and a surface mount chip is visible on the screen (magnified by a lot).
Closeup of the chip on the microscope‘s screen. It’s a Parrot branded IC from a hands-free bluetooth car phone adapter.
New toy… ahem, I mean tool! Finally a proper digital microscope to do some more intricate SMD work and such. (I could not afford a microscope like that so I used my "influencer" powers and had the company send me one. I try to keep sponsorships at a minimum but this seemed ok.) #InTheLabDoingStuff

My desoldering station on the workbench with the case removed and some wires attached to a buck converter circuit sitting next to it. The gun part and some tools are scattered around.
Modding my trusty ZD-915 desoldering station some more. The fan in it got horribly loud recently (after 8 years of use, so no complaints there!) and I thought I might as well upgrade it with a proper switching DC-DC converter. This is gonna suck. ;) #InTheLabDoingStuff

The backside of my ZD-915 desoldering station on my workbench. The fan opening is drilled out and the perforated original part is laying on the desk in a pile of metal shavings from the operation.
