Just finished the layout for the Positron Proton Pack Kit’s powercell!
The mounting holes have the same spacing as on the original powercell, but they’re now mirrored on the other side as well.
The cyclotron’s RGB LEDs are attached directly to the powercell via a 16 pin ribbon cable with a new low profile connector, which is polarized so it can’t be plugged in the wrong way.
There are also five locations for optional JST connectors for the rib LEDs, as seen on the video game pack. These connectors are also polarized.
The powercell connects to the positron via the FFC connector labeled I2C. The cable will only mate with the contacts on one side, so it too protects against accidentally plugging the cable in the wrong way.
A1, A2, and A3 are solder jumper pads for setting the address of the board. You won’t need to change these, as the board will have the correct default address for the kit, but if I ever need to add another powercell to someone’s kit, these pads allow the two to be addressed individually if need be.
It has a name!
What you see above is the latest revision of my proton pack / trap kit, which I will be having manufactured soon.
The biggest change is that I’ve decided to use Cat5 cable for the connection between the thrower and pack. This change was necessary because the new strobes are power hungry and it turned out the flat flex cable (FFC) couldn’t carry as much current as I wanted. The flat flex will still be used to connect the bargraph and the powercell, but the bargraph will plug into a module with a short FFC that connects to the Cat5 inside the thrower.
I’ve already ordered this new cable, along with with the micro switches for the thrower, and lenses for the powercell, cyclotron, and slo-blo, and a heavy duty Arcoelectric power switch. The cable and micro switches are included with the kit, but the lenses and heavy duty switch will be extra. (I intend to offer a wire harness with quick connects to go with the switch eventually so you won’t need to solder anything. )
Here’s some photos of those:
The first prototype came in last week. I’ve already ported most of the code to it, and the on-board 40W amplifier works great!
I haven’t yet updated the code to animate the new bargraph, but I’ll get to that soon, and when I do I’ll post a video!
Schematic is done. Layout + routing is almost done. Should be ready to order the prototype by Monday!
Here’s some photos that show the progress I’m making on the next version of my Proton Pack kit!
Comparison of original strobe with a single super bright LED being driven at 120mA:
The new strobes will change colors, and feature white, blue, orange, and green leds:
Here are some photos of the new style of bargraph with 28 LEDs:
Here you can see the size of the old style versus the new. The new style integrates all the drive circuity into the bargraph itself:
And here you can see the first prototypes of the new bargraph module. The white connector is for the 5mm LED that is at the end of the bargraph when used in a Trap kit. I’ll be releasing the trap kit soon after the new proton pack kits start shipping:
