Babbage’s Barrels Realized with Miniature Reflective Infrared Optical Sensors

Thanks to Edward for sending us this tip! Edward writes:

this YouTube video shows some successful beginning steps in building an opto-electro-mechanical computer that could theoretically be built using materials available in the late 1880s.

I am pretty sure you all must know about Babbage’s Barrels but I think this is a good link also:

I will have a finite state machine working soon and would love to hear thoughts on writing a compiler. A phosphorescent RAM and display drum is in the works also.
