Back in the day, kit radios were about as advanced as you could get with DIY electronics. You can still buy kit ham radios but the advancements that have been made in what is available for hackers is enormous. A full fleged computer the size of a deck of cards is amazing. This guy built an incredibly complex security system using off the shelf components that could have easily required zero soldering had he only used wireless sensors. His design is maybe a little over engineered (tamper switches on junction boxes?) and is probably much better than what any residential alarm company could offer. |

Back in the 60's through the 90's we also had Haltech and Halted Specialties, electronics supplies and surplus in Sunnyvale/Santa Clara, each about a mile from each other.
Many folks confused the names.
As I recall, both of them had resident cats as well.
My High School electronics teacher turned me onto them in 1969.
It appears Haltech is defunct, and not surprising since the owner was OLD when I was shopping/browsing there in the 70's - 80's.
Oh, looks like Halted changed their name to HSC and may still be in business.

Aside from many parts, I also bought my first of several surplus HeNe LASERS there in 1974.
