$17 for 3 break-apart boards, each containing gun (narrow strip) and target (larger).
IR arcade shooter gun + target w/prototyping space, needed since the designs come with 2 totally different flavors of target…Grrr.
The Makezine project’s article online says one thing, but the project designs on the author’s site show something entirely different. Since I planned to make the boards with flexibility built-in already (for other unrelated future prototyping & experimentation), I decided to also make it easy to cut traces around the IC socket on the back of the target board and arbitrarily rewire things if needed (probably so.) The rear silkscreen makes it more apparent if cuts have been made, as well as highlighting the cut lines.
Muttering to self about the stupidity of having coexisting proprietary and open designs…
Clearly, both schematic design and board layout are untested, but they should at least work for experimentation/prototyping.

$5.35 / set of 3; but you can now get the new smaller version here for $4.50
Designed more for vertical use, e.g. right-angle 9pin header plugged into a breadboard.
DS1337s on top, Supercap (I chose 1.5F) and 78L05 (SOIC version 5-volt regulator) on bottom, and one or a pair of [low-Vf] diodes makes for a batteryless clock module that will happily keep time with monthly charging, on anything from 7~18v [using regulator] or can be run direct on 1.8-5v.
Don’t forget to install the jumper-wire, and charge session[s] should total 24-48 hours per month for better results with high-ESR supercaps.
The regulator can also power other small circuitry; just keep in mind power dissipation and current rating (~1W or 100mA).
