Several years ago I designed a circuit to control various controls remotely using shift registers. It worked quite well, but I discovered that there were already circuits to do the same. These were MC145026 and MC145028. I now have a similar need, but finding these chips (I need through hole) is nearly impossible. Any help is greatly appreciated.

 

These days RC jobs are best done with microcontrollers.

Good luck

 

Well said and I would welcome the learning experience. However, I have a design to remote the position of the windmill in my front yard by detecting the vane position at 8 points. Using a wide opto interrupter will give 16 positions of the vane. Using my old circuit with shift registers or the remote chips seems more cost effective than the cost of using a microprocessor with all the programming interface costs.

CORRECT AND RE-DIRECT me if I am WRONG.
