    When projects start getting a bit more complicated than simply connecting one or two things to the Crumble, it can be a real pain making sure there are enough connections and croc clips don’t short each other…

    So I laser cut an acrylic base, soldered on connections to a Crumble and added some connector blocks and a USB battery, to make a nice and tidy setup for Crumble projects.

    I used hot melt glue to attach items to the acrylic base. I laser etched the areas to receive glue to make a good key for the glue to stick and to help outline where things were to go.

    For the USB battery, I didn’t want a USB lead hanging out of the side, so I opened up the battery block and soldered connections to the USB port power pins on the PCB (Not on the battery itself!) and made a hole in the lid for the leads to feed through. I added a little switch so I could cut the power when needed. Obviously, lithium packs can be dangerous, don’t attempt this if you don’t know what you are doing.

    It’s made life a lot easier since doing this adaptation!
