Bought the game Sherwood dor the C64. Fun game. Shooting arrows, jumping around on the platforms.

Bought a new game, Sherwood.

Bought this camera to use with my YouTube channel. Forgot to buy a sdcard. Hmm..

Best music and trianing scenes ever. Rocky IV.

Sunbathing my new esd mat, which stinks of rubber. Hoping it will help.

Playing with a STM32L0, and the cubemx nad cubeide. IR LEd/sensor. For a fridge door alarm. Last attempt was with a solar panel. This time with a CR2032 battery.

Updating the Ultimate64 firmware, and I see the best scanline emulation I'vr ever seen.

A friend I met through my YouTube channel donated this board for me. The Ultimate 64 motherboard!

I mod'ed the Denon PMA 1500AE, by adding a loudness circuit. Thanks to @pcbwayofficial.bsky.social @queenelaine.bsky.social for sending and sponsoring me with PCBs. youtu.be/dBOXJuC_H-c?...

LOUDNESS !

NAD 7120 Stereo Receiver from 1983. Fixed the dead radio. Blown transistor replaced supplying 12V. A nice feeling to be able to bring it back to life after 30 years.

Adding loudness to my dad's Denon 1500AE.

NAD 7120 Receiver. 2x20W. No power in the tuner section.

iPhone zombies. They're everywhere, and it is getting worse!

Winamp Skin: ASCII Amp 5x by mrd00d

I made a new video about fixing my amplifier youtu.be/d_n1VYs8T0c?...

Aaaand it works again. Re-flowed solder joints. Replaced output transistors. Adjusted quiescent current.

Re-assembling the stereo amp after fixing it. It's a puzzle to put the boards together with wires and screw.

The Wave 1981 Just recalled this movie name. Been thinking about it a lot lately, but could not recall it. My teacher showed it to us in secondary school. The movie sat with me for a long time. youtu.be/4qlBC45jk3I?...

My C64 keyboard PCBs just arrived. I was so excited, that I have cut my thumb, when I opened the package. The small pcb is for making it possible to use a ribbon cable as keyboard cable without crimping.

Another repair!

The dim bulb limiter is helping me bring up the rials voltage safely.

Nibbeling out holes for a dim bulb limiter

I need to build a dim bulb limiter youtube.com/shorts/o4m8d...

Just now tried Mechanic Nano Flux paste. Clear. Almost no smell.

New transistors are soldered in my amp

I measured Rfs pn and Vgs threshold in MOSFETs. Yes! youtu.be/zH2lFCjK0hE?...

Measuring key parameters on MOSFETs. Vgs(th) and Rds(on). This should tell if it's the real part or not. Turns out, they're OK!

First homemade cherry mx keycaps. Laser engraved. It is not perfect, I would like it darker. But it looks quite clear and it is faster, than I thought it would be. I used standard (DSA profile) blank key caps from AliExpress.

The video to go with this card will be released tomorrow (Friday) at noon GMT

Trying out the Analog Discovery 3, with an old amplifier.

Excited!

Bought an Analog Discovery 3. So excited in getting it. Will use it with software that can analyse amplifiers.

Recapping a PC Motherboard from 2006. Mostly TH parts.

Doing a recap of an old Motherboard for a friend. Grouping all caps into a table. Taking notes on an image.

Haha. Ok. Here is a dry one:

So cute this piano lesson book. Needed to get my mind off things.

The repair did not go as planned youtu.be/juFrexYFDvg?...

Good news. My Denon PMA 1500R is now playing again. Reflowing solder joints in the night!

While measuring, it kept coming back to life. Sure enough, cracked solderjoints seen in this area. Also tarnished resistors.

My colleagues laptop bios password reset. Another laptop from 2016 is not going to waste. The sane can't be said for newer laptops with bios locked and lost passwords?

You can find me here a lot of the time. Come and join. It’s a lovely friendly and safe space where lots of nerds like me share their projects and tinkering. Everyone welcome! 😍

I'm reaching out for repair help on YT youtu.be/ng8aARIZnwE?...

The brilliant @factorofmatt.bsky.social sent me a prototype of the next super clever C64 diagnostic cartridge he's working on. I will release a video tomorrow at noon! (GMT)

New blog post - first of the Mini VIC development logs. blog.tynemouthsoftware.co.uk/2025/01/mini... Part one covers the story so far and the plans for the revisited design.

Denon pma repair. Class AB amp. Scope shows positive and negative DC levels before push pull transistors. Good. Left channel, ok. Right channel dead. No dc levels, no signal. Seems to change when warming up.

I can see the input signal all the way into the power amplifier board of my Denon amplifier. The tone and volume boards seem ok.

Finally got to this repair project. Measuring voltages, without shorting out all the loose boards flopping around. Denon PMA 1500 R2
