Ghostbusters Project: Metalworks

Things have been a bit slow on this project for some time. Main reason is that I’ve been waiting for some key parts that prevents me from going further.

Last week, One of those items arrived.

The all aluminium proton gun by CPU64, and it is a beauty!

For some reason, I just had to start assembling it, filed the opening for the bar graph just large enough for it to fit, added some switches and buttons and the Clippard valve..

I lacked a tap for 1/8 inch imperial holes, so I could not finish the top button that should be there.

Also, I have only marked the location for the side knob and the heatsink. Still need to figure out the position of the gun rack to go below.

Hat light extends a fair bit below the wing, need to check out ref pics for these if I should cut it shorter or not. Most likely not.

Right now, a lot of wires just shaking lose inside, connected to nothing. I also need to make sure that the wires are not in the way for the pop out mechanism Chris (CPU64) has made. Another thing I need to figure out is how to attach the acrylic tip to the metal tube inside. I am thinking E-6000 or possibly hot glue.

As soon as I get the tap, I can finish off 99% of my proton gun. There is still some work to do, but mainly mounting electronics and rumble pack. I might 3d print some holders for things inside, or use the wall where the heat sink should be placed for getting a few screws for mounting things inside the gun itself.

Another thing I have been waiting for just got picked up by a friend of mine and is being delivered on Monday: Behold! My laser cut motherboard, complete with speaker holes!

This one is a bit scary as it was drawn and designed purely in CAD and should fit my Nick-a-tron shell, in theory, but I won’t know until I’ve actually tried.

I chose not to add any holes for rivets at this point, for obvious reasons 😉

(I just love how the mother board is first: upside down, and on the wrong side up. It’s almost difficult to place it more wrong =)

Ghostbusters Project: The first money shot

A couple of minor updates within the last few days, that in itself were not big enough to warrant a blog post, but now..

First off, I took the daring step of drilling hole in my shell for the split loom. I had previously 3d printed a loom holder, and it was time to jump off the cliff..

I marked off where the loom would pass through the shell, and step drilled the hole up to 30mm, which was the diameter of my holder, then used my dremel to cut down from the half circle to the bottom of the shell.

A little sanding and filing, and it turned out pretty good.

Can’t wait for my proper motherboard to arrive so I can start mounting things. I did have to bondo and sand and repaint a bit around the hole, but that was fixed as well as the bondoed piece on the right.

In addition to this, I got a new shipment of fun pieces. Not all of these are accurate, but to my defense, I ordered some of these prior to finding the proper ones.

Having almost all pieces in place, I decided it was time for my first pic with placement of most parts.

I still intend to replace most resin parts with aluminium, but until I have them, the resin parts will do.

It was about here I found how wonky some parts of the shell is. The upper left corner where the ion arm is supposed to sit had a height difference of 3 mm from the corner to the inner corner of the ion arm placement. I had to balance the resin ion arm (that I had sanded flat) on an m3 nut on the inner corner for it to not fall down.

To fix this, I decided to mask off parts of that shell, sand down the highest points and add loctite putty to build up a base. It took me about 45 minutes to fix, but the result was pretty good.

You can clearly see the bulk that was build up. Dry fitting with the ion arm leaves this:

Nice and flat!

The shell went out on the balcony for a bit of touch up on the hammerite black paint, and once that’s dry, most of the shell work should be done.

I also hot glued in my coloured lenses for the power bar and the cyclotron…

… only to realize that I have RGB LED’s in my light pack, and the program does four different colours, so I had to cut them off. Oh well 🙂

I also took out the metal parts and the black glossy plastic box of my 3d printed ghost trap, courtesy of countspatula and went over them with flat black before assembling again.

I have built in a remote control in my pedal to not have to use the hose for anything functional at all, and I decided to also wire up the LED on the remote to a small LED on the pedal. It is not very bright, but a nice little addition, I think.

Ghostbusters Project: Modifying the Clippard

One of the features on both the proton pack and the thrower (the “gun” if you will) on the Ghostbusters costume from 1984, is a Clippard Valve. It is apparently used for something in the real world. In the Ghostbusters world, it is a thing that looks cool.

A while back, I 3d printed a copy of a clippard to keep on my proton pack to keep the weight down, and sitting right next to the real deal, it looks pretty good!

The twist knob still needs a little more work, but I’ve got a resin copy of that coming in, but what I’m devoting THIS post to, is modifying the original Clippard (The one that is supposed to go on the gun) to work as a volume controller for my proton pack.

After first opening the clippard and taking it apart, removing everything on the inside, I had to first saw off the round tab on the bottom  and drill a hole, allowing the cable to run through.

I also 3d designed a huge spacer/holder for the potentiometer that was to be placed inside the clippard.

I needed to cut down the pins on the potentiometer in order to make it fit properly, and once it was cut down and the wires were soldered, this what I was left with.

In the picture you can also see a spacer that I threaded and had screwed in place, and blue painters tape on the threads and rotary part of the potentiometer. You’ll see why shortly…

To make sure I had enough room for the solder joints, I drilled out the top of the inside of the Clippard with a stepper drill, just to give some more space. The enclosure will be held in place 6 mm further down where the inside diameter will match the 3d printed enclosure perfectly.

The potentiometer fit like a glove into my 3d printed enclosure.

Pushed down into the Clippard with the cable going out through the hole I drilled in the bottom:

When I started to put the clippard together, the thin axel of the potentiometer didn’t exactly look like the original… so I had to do something here. I took the original threaded part that was hooked up to the clippard and the rotary knob, and put it in my power drill with a metal blade to cut off a small piece.

It was still larger than the potentiometer on the inside, so a few turns with painters tape was just right to center the brass bit.

Finally, attaching the knob at the top again, and I now have a potentiometer for the volume built into my Thrower Clippard!

Can’t wait to actually fit this on my pack in the (hopefully) near future.
