Hello -
A couple of weeks ago John asked what we've been up to. My work has been insane during the last year, but I've had a little time to work on a new project. It's a marker and loading system that I plan to install in Small Fry. Someday. I was shooting for a low-profile, small system. Here are a couple of videos. https://youtu.be/oh6uJ9zMPOk https://youtu.be/Ot8O-nX3qCI The videos show an early test of the loader system. The marker is a Dangerous Power E1. A stepper motor pulls back a ram using a rack and pinion mechanism, allowing a paintball to fall into a loading chamber. The stepper motor then advances the ram about 75% of the distance used to cock it. At that point, power to the stepper is cut and a spring moves the ram the rest of the way and applies pressure to push the paintball into marker when the bolt opens. I may be able to use a standard DC motor instead of a stepper (similar to how an airsoft gun cocks and loads), but I need some kind of clever clutch to slow the ram so it doesn't puncture the paintball. The stepper gives me a lot of fine position control. For elevation, the marker pivots on the feed mechanism, so there's no issue with mis-alignment of the feed port at different elevations. The whole system is currently driven from a Raspberry Pi2 running windows IoT. There are SUPPOSED to be IoT X-BOX 360 wireless drivers available so I can control the whole tank from a 360 controller. Those drivers are bugged right now, though. If someone wants to help me re-write them, speak up ! - Doug -- -- You are currently subscribed to the "R/C Tank Combat" group.
