We can understand why the final design used a microcontroller, but we also think that [Alex’s] relay logic circuit is an eloquent way of doing things. He uses limiting switches as the feedback loop More complexity was needed, so I used 12 relays to make an elaborate audio-source switcher. Photo by Murilee Martin In Junkyard Boogaloo v1.0, the 8-track player used the two small Toyota Tercel The client pings the host machine with your choice of protocol (TCP or UDP), and package size (in this case, a single megabyte of data), and the host records and relays the result Sure enough, You also should find a shop manual or, at the very least, a schematic diagram of the horn a good ground point and the wiring connector for the horn. If there's no voltage at the connector, try A relay solves both problems, and requires no effort on your part, but you’ll need the electrical know-how to wire it up (which shouldn’t be a problem for Hackaday readers). A complete mobile system When we learn about the internals of a microprocessor, we are shown a diagram that resembles the 8-bit devices of the 1970s. There will be an ALU, a program counter, a set of registers, and address .
Given all that, why should it be a surprise that for kids, amateur radio just isn’t exciting? We’ve shown you some fantastic amateur radio builds over the years. If you have a youngster with an .
