A Look Inside the Geochron Clock
There are plenty of cool clocks out there, and maps by their very essence are cool, too. But a map that’s also a clock — or is it a clock …read more Continue reading A Look Inside the Geochron Clock

When you’ve got a piece of interesting old aviation hardware on your desk, what do you do with it? If you’re not willing to relegate it to paperweight status, your …read more Continue reading Jet Engine Tachometer Turned into Unique CPU Utilization Meter
Serially, Are You Syncing or Asyncing?
I know you’ve heard of both synchronous and asynchronous communications. But do you really know the differences between the two?
Serial communication was used long before computers existed. A predecessor is the telegraph system using Morse Code, one of the first digital modes of communication. Another predecessor is the teletype, which set standards that are still used today in your Arduino or Raspberry Pi.
All you need is two wires for serial communications, which makes it simple and relatively robust. One wire is ground and the other the signal. By interrupting the power with predefined patterns, information can be transferred …read more
