They&#8217;ve all had an Arduino Uno mounted in the top corner.<\/p>\n\n\n\n<p id=\"block-470d447a-612d-4e5f-8371-405811201bd8\">Since I started using Raspberry Pi Picos, I came to the decision to replace one of the Arduinos with a Pico. So when I received my latest order I thought this was the perfect time.<\/p>\n\n\n\n<p id=\"block-15a3e5c1-ff9e-43b4-8ae6-2a2666cd8e81\">Mounting the Pico, as always, was the main challenge. I first started with a piece of polycarbonate. Cutting it to shape and drilling it to fit on the spacers I already had installed went well enough, till I tried marking out the mounting holes for the Pico. It was then that the scriber I was using cracked the sheet in half and stabbed me in the hand.<\/p>\n\n\n\n<p id=\"block-c1816e3e-b89c-4b98-bf97-96cd01cee2f7\">Back to ye olde drawing board.<\/p>\n\n\n\n<p id=\"block-d0616495-93e4-43c4-80b5-fe5048b449f6\">It was getting late and I was on the verge of giving it up for the night, not wanting to be marking out and sawing large chunks of plastic, when I saw the offcuts from the robot bump sensors. They were too thin to fit on the existing spacers, but big enough to fit a Pico.<\/p>\n\n\n\n<p id=\"block-28c5b144-b59c-4c29-926b-19f35b600a13\">I drilled one of the bits of plastic with mounting holes at either end and countersunk them so the screw heads would not protrude and interfere with the USB cable. Then I drilled new holes in the base and fitted the carrier to the base.<\/p>\n\n\n\n<p id=\"block-4b0b43d9-2375-4fa4-9258-5cb5777ee722\">All of this was only possible because I&#8217;d already decided to screw the Pico onto the carrier using some 2mm machine screws I&#8217;d had for ever.<\/p>\n\n\n\n<p id=\"block-78375101-3c66-4af7-8c11-12d119813c9a\">I marked out the mounting holes for the Pico, one at a time. In the end I only drilled 3 holes because it&#8217;s fine. I didn&#8217;t want the Pico crushed against the carrier so I stuck some self adhesive foam on the top of the carrier to cushion it.<\/p>\n\n\n\n<p id=\"block-ebb12374-416c-4842-bab0-167ecafaa9a8\">I sat down and soldered header pins on one of the Picos and then set about fiddling with the diminutive nuts and bolts. Now I have a test bed for Pico development. The picture at the top shows the Pico in the top left. Then there&#8217;s a 7805 power module and a legacy LCD module. Most of the space is devoted to the breadboard itself, while an old X-Box (?) controller joystick takes up the bottom right.<\/p>\n\n\n\n<p>The new setup works pretty well, but when plugging wires into the Pico, the foam has the tendency to squish, so I might need to investigate an alternative.<\/p>\n\n\n\n<p id=\"block-20d7ed15-39b4-4e60-82cd-ac9197eee22b\">Other than that I&#8217;m pleased with the result.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>For a few years now I&#8217;ve had a collection of breadboarding modules that I&#8217;ve used for prototyping.
