Discussions keep coming up about a signal control board, especially now that there seems to be several choices for cheap O-gauge track signals.
That being the case, I figured we'd start a new thread and see what features might be desirable in something that would be in kit form for users to build. I'm thinking we'd sort out a feature list and then whittle it down so that it could be made in an inexpensive manner with common parts. I'll start with a few attributes and we'll go from there.
- Low cost! (one of the primary objectives)
- Stand alone, doesn't need any ITAD or other sensing device.
- Multiple types of input, i.e. IR, insulated rail, etc.
- Drives two and three aspect signals with appropriate delays for yellow & green (programmable?)
- Drives road crossing crossbuck signals directly.
- Direct drive of LED or incandescent lamps.
I'm thinking a thru-hole PCB design with a inexpensive parts BOM that can be easily assembled by most folks that can solder. Having a board greatly simplifies the task of assembling one or a number of these.
Let's all join in and toss some ideas around!
