Yesterday I mounted all the components in the lower half of the case.

Today’s job is to do the top half :-)

Up until now all the components of my RetroMatic 2000 have just been loosely placed inside the case.

Well now all the bits I need to fix things down have started to arrive in the post, so time to start making things permanent!

After drawing a (dotted) line under my entry for the Retro Challenge, I took a week off from the project to have a rest.

For the Challenge I was able to demonstrate pretty much everything, but it wasn’t very reliable, and bits were breaking and being repaired in between shots of my wrap-up video!

So time to revisit it, and get it up to scratch to be a usable product.

It’s the last day of April, so it’s the end of the Retro Challenge.

I’ve achieved pretty much everything I wanted to with the Challenge :-)

I’ve made a quick video to explain my entire project (without you having to wade back through 18 long blog posts).

It’s the last day of the Retro Challenge, so I’m going to try to solder up the main circuit board, so I get a finished product, rather than just a collection of breadboards.

All set for a day of soldering. Including a cup of tea in my favourite Dr Who mug :-)

It’s time to build all the user-interface components for my RetroMatic 2000 into the wonderfully retro case I acquired.

Having worked out the “final” connections to the Arduino in my last post, it was time to update my veroboard circuit diagram to reflect it.

Which of course meant a few subtle changes to my pin assignments to minimise the crossing of wires ;-)

I’m in the final straight of the Retro Challenge, so trying to get all the components of my RetroMatic 2000 to come together in one package.

But I’m running out of pins on my Arduino!

It’s time to return to my Gotek USB floppy disk emulator, and see if I can add some authentic-sounding sound effects.

I’ve previously written about my plans to interface to the Gotek hardware. In that post I linked to solutions other people have already used for sound effects.

They generally involve a pure hardware solution that generates a ‘click’ on a speaker every time the drive receives a ‘head step’ signal (to simulate the sound of the stepper motor). But that means the sound effect happens if any drive attached to that cable is active, not just the Gotek drive.

As part of my RetroMatic project, I’ll be using a rotary encoder to control an Arduino. This will control menus on an LCD display, which will set the parameters on a video converter board, and the configuration of a scanline generator.

But my RetroMatic also contains a USB floppy drive emulator. Since I have the Arduino there anyway, and the video converter is controlled by a rotary encoder, I wondered if I could also control the USB floppy emulator via another rotary encoder?
