![]() The next approach I tried was a die cut adhesive vinyl decal. If they are off even by a little bit you will notice it once its projected. With this approach you need to register the decals perfectly on top of each other. Then after it fully dried I would put another decal on top of the first decal. I would cut a piece of transparency film then put the water slide decal on top of it. These were also not very opaque but you could put multiple ones on top of one another to make them less translucent. Instead of projecting a black logo it looked smokey gray since it still letting light shine through it.Īnother approach was water slide decals. In both cases the black image I printed was not as opaque as I would have liked. ![]() I used some designed for a laser printer as well as an inkjet printer. The simplest and most straight forward way is to print onto clear overhead transparency film (Can't believe this stuff is still around in the digital age). I experimented with multiple ways to make the slide. You want to replace the thin film slide with the logo you want to project. Each is in a plastic frame that can be opened up. This projector comes with an assortment of Halloween themed slides like skeletons, witches, ghosts, etc. It should never go out in an indoors setup but its nice to have in place just in case. Since this projector was designed to handle outdoor rain and snow I'm assuming that's why the fuse was there. It even comes with a spare fuse in there as well. ![]() The plug has a little sliding panel on it. If you wanted to drive the projector with a 3VDC source you could still do that it just wouldn't be as bright.Īnother advantage of using the included AC power cord is that it is fused. I'd like to still be able to see the projected image even if the room lights are on. Based on this I decided to use the AC input vs a 3VDC input to achieve a brighter image. My assumption is that circuit board that converts the incoming 120VAC to 3VDC is also driving the LED in such a way to maximize brightness. The supply I was was capable of much higher amperage but the LED only draw a small amount. In this arrangment the current draw was a very steady 100ma and the bulb was noticable dimmer. I then hooked to up to a very high quality DC power supply set to 3VDC. The current had a saw-tooth profile oscillated between 250ma to 400ma. ![]() When using the AC input I was getting a steady 3VDC input to the LED. I hooked it up to a scope to see what was going on. My original plan was to just use drive the LED directly with a 3V source but when I did that it was not as bright as when using the AC input. I was impressed with the amount of engineering in this little projector. There were also multiple lenses in the optics path. Once I opened it up I also noticed that the LED was very big and mounted to a large metal heatsink. This projector is AC powered and has a small circuit board in it that transforms the 120VAC to 3VDC. It was fairly low cost, projects a very bright image, it attaches to a swivel base so its easy to adjust once mounted, It has a focus adjustment, the projected image is on a "slide" that can be pulled out and changed. There are a ton of similar Halloween and Christmas projectors out there but this one was unique as it had most of the features I was looking for. I couldn't find any info on them at the website so they may be discontinued as its not as fancy as some of the newer ones. You can still find them on Amazon for around $20. ![]() The projector itself is a re-purposed Gemmy Halloween projector. If you see areas where you think it could be improved please share your cmments in the thread. Pleae feel free to modify and adapt it to suit your particular needs. The following tutorial is what I came up with to meet all of those requirements. Plug and Plug for Batman66 LE owners for game controlled on/off projected image Projected logo can be rotated to any angleĪutomaticaly powers up when game is turned onĭoesn't draw power from spike node boards So I started making a list of all the requirements I wanted:īe totally reversible with no damage to gameĬhangeable Logo (Stern Batman66 or Dark Knight, DE Batman, or Sega Batman Forever) I wanted something that would allow me to have more flexibility in where I could place it. Stern already makes a great looking Batsignal projector for their Batman66 game but It wasn't going to work well in my low ceiling game room (my Batman topper barely fits). When you are playing your Batman game its way cooler to have a giant Bat Signal projected into your game room while you play. I designed mine with the 1966 style TV Bat Signal logo but you could also change the logo style to fit the 1991 Data East Batman, 1995 Sega Batman Forever, or 2008 Stern Dark Knight. This is a tutorial thread on how to make your own Bat Signal Projector for your Batman Pinball machine. ![]()
