On this, the 74th anniversary of the unveiling of the ENIAC, I've decided to post a couple of things I've been working on. The first is the 3D model of the ENIAC mentioned before. It's designed using brlcad, from the Ballistics Research Lab. It just seemed too appropriate to model it using the tool devleoped where it lived. The thingiverse link is: https://www.thingiverse.com/thing:4164825 The second thing is a draft of a chapter from a book I'm in the very early stages of. It describes the basic circuit designs used in the ENIAC with SPICE simulations of them. The layout and formatting are based on the old Army Technical Manuals of the time. http://cs.drexel.edu/~bls96/eniac/ch1.pdf Enjoy, BLS
