The Monday Jolt is a new series about microcontrollers and electronics that appears in MAKE every Monday morning.




For today’s Jolt, I asked German hacker “Kopfkopfkopfaffe” to create a how-to on transferring both sides of a circuit design onto perfboard. Perf is great for creating a quick, robust test board for a circuit you’re prototyping, but with no set traces and no silkscreened circuit diagram, like an etched PCB, it can be hard to keep track of where your components go as you solder them. You can mark the board with a pen, but this can look messy and is prone to error. Kopfkopfkopfaffe uses the toner transfer method to deposit a print of his circuit directly onto the board, using an iron.


Check out his how-to in our Projects section to see how it’s done.

    Sorry ’bout that. Fixed. Thanks.

    These Step by step projects are cool, but how in the world do you make the small images under the big ones bigger. I mean it’s nice the small ones are there and all, but clicking on them does nothing, and they are too small to actually see any detail.

      This is a glitch that we’re currently working to fix. Sorry for the inconvenience.
