Day 42 - The Final Countdown

Essentially I've finished. I've some videos to edit/upload and pictures from a previous day (control panel creation/wiring) but I'm too excited so thought I'd pop these up now anyway :)

Thanks to Harry for the extra hands, tools and woodworking skills, Pierre for the tank, lettering and other artistic direction, Calla for the drill press and creation of a LED block, Brian for spraying and everything else, plus a few others....

Feel free to pop round for a game or two of something.

Day 41 - Stuck Art

Tonight we (me and Brian) put the tank stickers on. Easy enough as they were small (and I wasn't doing it). Almost job done, just waiting for the bezel undercoat to dry then it's on with the black paint and tidy up.

Yes, I know it looks like she's pointing at the flipper button (or the Sun).

Of course, it wouldn't be complete without a blatant plug, so visit Brian at if you need bike training or advanced bike training and happen to live in the north-east of England :)

The bezel was just four pieces of hardboard (about 2mm) stuck together with tape on one side and then glued.

Also, because the stand was the wrong angle and position for the monitor to be viewed nicely I made use of the monitor mount I created originally.

Day 40  - Control Panel Is Born

With the plastic cut yesterday, I cut out the marquee and mounted it. The aluminium is screwed in at the top (for changing/access) and bonded to the wood using contact adhesive at the bottom.

I fitted the pinball buttons (also double as left/right mouse buttons I hope). Rather fetching I think and better than the black I was going to get.


After checking the trackball and buttons fitted I measured and cut out the holes for the joystick into the MDF then cut out about 3mm for the trackball to fit (as it has to span the MDF and the polycarbonate).

After this, I placed the art for the control panel onto the MDF, peeled back the protective cover for the polycarbonate and placed this on top sandwiching the art between the two.

Then just a simple matter of sticking the buttons into the holes, fitting the trackball bezel and trying it out in the cabinet.

There's some videos to be edited for this that will be uploaded shortly.

All that is left is:
1. Put on side-art tanks
2. Wire up control panel
3. Fit glass and monitor with a bezel (no idea yet, probably hardboard)
4. Play games

Day 39 - Polycarbonate

The polycarbonate arrived (I bought 2mm). I bought this as it is supposed to be easier to cut than acrylic but scratches easier. One piece for the control panel and one piece for the two halves of the marquee (the marquee is sandwiched between)

First we taped where the cuts were going, put some thin wood below to strengthen and support it and used the jigsaw with a metal blade to slowly cut the plastic in half. Harry did the cutting as he is a master builder and I was too scared. Remember to keep the backing tape on.

After drilling all the holes (except trackball) into the MDF (18mm)  it was off to Calla's workshop to drill the holes with the 28mm wood spade bit.

First we placed the polycarbonate below the MDF control panel and taped it up tight with gaffer tape, then we placed another piece of MDF below that (making a polycarbonate sandwich) and clamped it. The idea is to stop any vibration when cutting.

We set the drill speed to it's lowest (500rpm) and went slowly through the mdf into the polycarbonate (thereby making everything match up exactly).

Some holes couldn't be done (too far for the drill press to reach), so I did these back home with the hand drill on slow speed. The idea being to go slow but steady resulting in scraping away of the polycarbonate rather then forceful drilling.

While we were there he soldered wires onto my little switches (for pause and power) and showed off his magic tricks by twisting the wires in a drill.

If you're ever in the need for a high quality but cheap guitar pedal (diy or built) then visit him at, international delivery too :)

This is the finished article (with covering tape on).

Day 38 - Shiny Shiny Stuff

After getting lost by the hapless City Link my art finally turned up and have done a splendid job. Click to zoom.

This is the marquee done on special back-lit paper:

This contains the two side pieces (tanks from metal slug), the control panel and I had some spare space so created a little something for the monitor bezel (to go at the bottom). The QR-barcodes, you'll just have to scan to see where it takes you :)

Here is the bezel closer up:
