No need to print circuitry? I just saw an article about the Paperduino on the MAKE blog: [blog.makezine.com] Guilherme Martins in Portugal designed an Arduino clone built on a cardboard substrate. The component layout and wiring, top and bottom, are printed on paper and glued to cardboard. You poke holes with a pin and shove the component pins in the holes. Then you wire point-to-point following the printed wiring diagram: [lab.guilhermemartins.net] It seems to me that this is a good bootstrapping technique where circuit boards are not available or too expensive. It would also make it very cheap to supply alternative circuit designs if components need to be substituted because of availability or cost. https://reprap.org/forum/read.php?70,23482,23482#msg-23482 Wed, 16 Sep 2026 08:07:33 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?70,23482,23496#msg-23496 Re: No need to print circuitry? https://reprap.org/forum/read.php?70,23482,23496#msg-23496 Forrest Higgs Plastic Extruder Working Group Tue, 12 May 2009 21:08:12 -0400 https://reprap.org/forum/read.php?70,23482,23490#msg-23490 Re: No need to print circuitry? https://reprap.org/forum/read.php?70,23482,23490#msg-23490 HanClinto Plastic Extruder Working Group Tue, 12 May 2009 16:19:31 -0400 https://reprap.org/forum/read.php?70,23482,23486#msg-23486 Re: No need to print circuitry? https://reprap.org/forum/read.php?70,23482,23486#msg-23486
However, this may actually do better for those who can get the individual bits cheaply, like me. (Skycraft Surplus--you name the transistor, it's quite possibly there! :D )

Let me know when an Arduino-clone diagram is released, along with a compatable bill of materials attached. :D]]> Lethosos Plastic Extruder Working Group Tue, 12 May 2009 14:41:51 -0400 https://reprap.org/forum/read.php?70,23482,23482#msg-23482 No need to print circuitry? https://reprap.org/forum/read.php?70,23482,23482#msg-23482
