Machine Ideas is operated by Andy Geppert as a freelancer and consultant.
I specialize in the mechatronic systems realm, from custom machine design through build, bring-up, test, and deployment.
A recent project is an Interactive Core Memory Kit called Core64 (and Core16). It is a product aimed at the educational and vintage computer enthusiast markets, or anyone interested in experimenting with core memory.
