Altium recently announced CircuitMaker, their entry into the free/low-cost PCB design tool market. They’re entering a big industry, with the likes of Eagle, KiCad, gEDA, and a host of other tool suites. We had a few minutes to talk with Max in the Altium booth at World Maker Faire, and even got a bit of time with the tool itself.
Hands on, it definitely has the look and feel of Altium Designer, right down to the familiar yellow and green boxes for schematic and sheet parts. Center stage was the 3D view, a feature which Altium has had in their software since the late 90’s.
CircuitMaker’s website is pushing the collaboration aspect of the software. Design choices can be reviewed and commented on in real-time. This also suggests that the data files will live in Altium’s own cloud storage system.
CircuitMaker is still in the pre-beta phase, but they’re looking for beta testers now, so head over to the site and sign up!
[Cliff Miller] pointed out this incredible project from 2004. [John Pultorak]’s journey began in late 2000 when he decided to build a 60’s or 70’s era minicomputer. While gathering technical documentation, he found some interesting information on the Apollo Guidance Computer and felt that was the way to go. The AGC was the first integrated circuit computer ever built. Designed by MIT in 1964 it was constructed from ~5000 ICs, almost all 3-input NOR gates. [John]’s version uses late 1960’s 74LS TTL logic which gains him a 10 to 1 reduction in the number of ICs. A good thing when you have to do ~15K wirewrap connections. He also used flipflops and register chips instead of building everything from NOR gates. [John] essentially built the AGC three times: First, he coded a simulator in C++. Then, he imported the logic design into CircuitMaker to verify that it would actually work. Finally, he built the 3 by 5foot machine. He’s provided an amazing amount of documentation for anyone that wants to explore this device and the overview alone is well worth a look.
