This was a starter project of mine around late 2005. At the time I had interest in selling an upgraded drop-in circuit board for Shocker Sport markers. Ultimately I didn't release the board, in fact the project didn't progress into an actual prototype, but it was still a fun project that had potential if more people owned the marker.

At the time, I was in the process of testing my Euclid boards for the newer Shockers, so I had a functional firing cycle that could be expanded upon. In this situation it meant I would need to expand the board to allow functionality for a second solenoid (for controlling the bolt movement). This isn't hard to do, although I'm not an expert programmer so my new dual solenoid code is/was nowhere near that of the professionals like Tadao or NoX.

I posted a thread about it on the old shockerowners.com, and I did receive some positive responses on the idea of making the board. I figured it would cost around $100 each since the board would be possibly less expensive to produce due to the large components. For this reason I decided to solder up a hand-made prototype. After that I made a DIY-board version.

The board worked good but it was too large and bulky to fit in a marker. The next step was to design the actual circuit board so I could have a prototype batch made (although this never happened). Here's the schematic for my first prototype version:

Here is my list of planned features for the board: (note that some of these are not present in the above schematic)
· External firing mode switch sticking out the front of the marker
· Ability to use the LS board stock slide switch if equipped, otherwise a connector is provided for a relocated power switch.
· Optional connectors for two external LEDs, designed to be added to the rear of the marker. All you'd have to do is drill the holes yourself and insert the LEDs.
· Ability to add anti-chop eye hardware through an auxiliary connector. Not much point in this, but it's still cool to have for maximum paint feeding reliability.
· On-board tournament lock switch
· Future expansion connector (speaker, secondary LED indicators, etc)
· Programmed with multiple firing modes and adjustability for all the common firing parameters.
· Built in 9v snap (oh yes!!)

I designed a prototype circuit layout (above) but never actually went forward with making a batch to test. I figured the market for the board was so low that I mind as well not even bother. It's not really expensive to have prototype circuits made, but I found other things to prototype instead. To that end, ultimately I took the code I created for this dual-solenoid Shocker Sport board, and applied it to my multi-purpose Proclus boards as an optional feature. So, in a way, I did get to use the board in a real game.....just not quite how I intended.

Ah well, it was a fun idea...
