My Happy place. 😊
Still lots of unpacking to do but I'm going to have a bash at setting this up.

It arrived just before the move and I've been itching to have a play. ☺️

Merry Christmas one and all, I've been so busy moving I've done eff all.

I'm not going to go without a tree here's a bent bandsaw blade and COB LEDs! 😂

New house shenanigans!

Went to plug the washing machine in which I assured Sam should be straightforward only to be greeted by a seized valve on the cold and the other is furred to oblivion.

I changed the cold infil but it was tense as I've never done any plumbing before. ☺️

Move day is tomorrow so it's the final boxing up. See you in the new place Super Printendo! ☺️

Throwback post - The CrawlerBot is responsible for some of the most dramatically tense footage I have ever recorded. ☺️

The garage is nearly all moved and we spent the weekend cleaning the new place.

Fun fact, you can steam out furniture marks with a towel, clothes iron and a brush. ☺️

Gave the new place a look over and set up dehumidifiers etc.

The internet is all set up now too. It is... Faster... ☺️

There were some interesting bits left in the loft and the garage even came with a set of screwdrivers! 🥳🎉

I'd nearly finished the garage when the light decided to up and fail.

Thought I'd make the best of it. 😂

RIP Cary-Hiroyuki Tagawa. He was in so many amazing things.

I named my Arduino programmer after Shang Tsung a couple of years ago (because it can lift and drop souls.) and the guy was a legend.

Power washed the tanks in preparation for the move.

Which is a completely normal thing to do. 😂

My MiSTer Multisystem2 Analogue arrived (at an alternative address) and with the move and everything I should be able to get to play with it some time in March! 😂

I've got as far as I can with an analogue output on the Bluetooth cassette.

There's too much variation in tape images/hardware and I can't get a one size fits all.

I'm going to try a Schmitt trigger setup which should add some consistency.

i'll assemble a board and see what it can do. 🙂

It looked bigger on the web site... 😂

If everything works out, I should be able to start work on the largest project I have ever done soon, it's as big as a house!

(Because it's a house!)

It's been a while but I'm over the lurgy hump.

Normal service will resume soon! ☺️

I'm going for a battle of the amps with a set of hot swap coils.

I need one that has the right dynamic range for the decks at really low amplitudes and also has enough 'torque' to give a reliable zero crossing.

I have a sliding scale of 'stuff' in my head and I'll spend some time feeling it out.🙂
November 16, 2025 at 10:33 AM
The amp isn't agile enough to do a snappy rising and falling edge at low volume so I'm playing with dual wound coils.

I have a 100/600 turn setup at the moment and a switch at the side to choose but it's rubbish so I'll try two separates. 🙂

I've been using a .tzx of StrangeLoop to test loading games from a Bluetooth cassette but it has always been weird.

I have an original copy and the game loading speed is about 8-10 seconds faster than the .tzx. it's not the deck speed, that's been checked.

I might try and rip my copy. 🤔

Got a cheapie Bluetooth Cassette Adapter to play with.

I have an idea that ought to be interesting and I'll pop it open tonight and take a look. ☺️

Oh yeah, about that pause detection.

The full Arduino is overkill but the attiny doesn't have hardware serial which is needed for snappy pause response from the Bluetooth module.

Luckily there's a gpio pin on the module that pauses if you short it to ground.

I'll need a PCB for this. 🤔

Hello!! I'm working on a tape loader device type thing and I want to give it something tricky to chew on.

What are the trickiest loaders fo the C64 and Speccy? I'm currently loading StrangeLoop and Sanxion without issue and I'm after a challenge.

Suggestions gratefully received! 🙂
October 27, 2025 at 4:43 PM
I have a plan to put this loading business to bed once and for all.

If I'm right, it should 'just' be a case of matching the coil to the Bluetooth amp to get a wide enough frequency range with no distortion.

There is also HF noise on the output that triggers a double edge detection.

Popped round my local shop and found this highly amusing.

A new Pi 500 was released today, the Pi500+. The keyboard is pretty nice and goes rather well with FatScreen #3. ☺️
