This is also the source for information on the Rocketeers Of Central Indiana (ROCI), Section #625 of The National Association of Rocketry (NAR). Feel free to check here for information about ROCIs launch events. The launch events are conducted throughout the warmer months at the Academy of Model Aeronautics' Headquarters and Aeromodeling Center in Muncie, Indiana. This facility is the finest flying field in the state and ROCI is proud to be the exclusive host of the rocketry events held there. ROCI is not currently conducting meetings as we have lost our meeting place.

I will after I get the other boxes running the latest version of the firmware.

I let the system sit in a powered-on state for a few hours yesterday. As I suspected, there is an occasional random bit of data received by the pad controller. I don't know if this contributed to the device hangs we were experiencing or not because I had already made changes to the x-ceiver code to make it more robust. In a two-hour period, the controller received six extraneous messages and rejected all of them without problems. I was able to send and receive messages on the system after this long idle period without restarting anything. That doesn't mean that I've definitely fixed the problem but, at least on my workbench, it seems to not be an issue.

Also, I've found a source for some small LED displays that are supposed to be "sunlight-readable" so I'll pick one up to play with. Still looking for a larger one that might work better on the Launch Control panel.

I changed the display to show the pad numbers a bit larger.

I'm working on some new features. I don't know when they'll be ready for testing but I think you'll like them.

If my missing banana plugs show up tomorrow I should be able to have enough controllers ready to control 48 pads.

Another update because I like talking to myself...

The system is now complete and ready for testing. Everything has been updated to the current software. There are one launch control box and eight pad control boxes (four left and four right.) Each pad control box is designed to handle six launch pads so we have the capacity to control a maximum of 48 pads.

In bench testing, everything seems to function as designed but it will all need to be field-tested. I will continue to refine the design over time as it is still not feature complete yet. I still want to add an emergency shutdown switch for the RSO and people seem to want to have the ability to launch more than one rocket at a time. Coming up with a self-explanatory user interface for the latter is the issue.

In any case, the boxes are being charged for use at the next launch.
