1/6/2015 Backbox, Cabinet, etc

It’s been a busy couple of weeks here at the OPP.   This entry is going to be pretty scattered and I apologize.  Changes are happening to the playfield, cabinet, backbox, and pinball framework.

I’m working on the backbox during the time that I have to wait for the playfield to cure.  Last layer of polyurethane was on 12/27/2014.  Final top coats are normally supposed to be cure for 3 months, but since the playfield is going to be covered again, I’m hoping waiting 3 or 4 weeks is sufficient.

I picked up a backbox on Monday (12/29/2014).  After taking some measurements, I am much more excited.  Right now, if you look at previous pictures of the power supplies, they are all mounted on a piece of plywood.  That isn’t a good long term solution.  After turning on the supplies to see which direction the fan blows and taking some measurements, I’ve found I can mount them at the top of the backbox.  That will exhaust the heat out of the top of the back box as efficiently as possible.  The remaining 2/3 towards the bottom can mount the speakers, amplifier, main controller (aka Raspberry Pi, or mini-ITX board), Max Power board, monitor, etc.  I’m still thinking about how I’m going to mount the LCD screen, but my current thoughts are to use the EMI shielding metal from the original backbox and form some metal brackets that flare out larger than the monitor for easy access.

On the amplifier and speakers, I’ve decided I’m way too lazy to figure out anything for myself.  Because of that, I ended up just following Joe’s lead.  For Christmas, Santa brought me a Lepai amplifier (LP-2020A+) and Lanzai speakers (MX53). The amplifier can be powered using a 12V supply, so that will be connected to the Max Power board which can provide 12V.  Sweet. One less thing that needs to be plugged into AC power.  The controller can also turn the amplifier on/off by enabling/disabling the PC power supply voltages.

Finished my big order to pinball life last week.  It includes all the LED bulbs.  The bulbs cost $57.  The playfield was only $75.  Hmmmm.   I would not have guessed that I would be spending that much money on bulbs, but if it achieves the look that I’m hoping, it will be well worth the price of admission.  The order also contained all the little annoying parts that I was missing:  new posts since many of them are broken or chipped, leg levelers, leg brackets (cabinet didn’t have any brackets on the front), and plastic channel for the playfield glass.  I tried a couple of places to find cheaper parts, and pinball life definitely seemed to have best price/selection.  This is my first order from them, so we will see how they do.  I was hoping this would be the last major order, and the day after ordering, I realize that I don’t have a start button.  That is easy enough to dummy up, but I’m annoyed I didn’t notice it earlier.

Joe is sending me a lockdown bar and a couple other random cabinet parts, so that I can install the playfield into the cabinet.  That’s a pretty big step for the project.

Started re-installing the top playfield parts.  The only annoying thing is that they all have to  be stripped off again to install the final artwork on the playfield.  Of course there is no playfield artwork, but somebody has offered to help.  It is going to be a heck of a lot better than anything that I can do.  I worked two or three days on some cabinet artwork, and in an hour, he threw something at me that was significantly better than what I did.  It once again proves how crappy I am at artwork.

The pinball machine has been entered in a contest.  This gives me a hard end date (7/10/2015- 7/11/2015), and forces me to hopefully get something fully working by early July.  The machine is entered in the Restoration Throwdown Contest (RTC) at the Pintastic New England show.  Here’s the link.  This is the first New England pinball show for quite a  few years and I’m very happy to see somebody getting a show up and running so close to home.  It will be interesting if people consider the Sharpe Shooter III a restoration, or something else.

I was going to hold the post off for a few pictures, but I can add more photos next update.  Seems like there is enough info, and I hate when the information gets too stale.
