I signed up to help with a STEM event at work and was going to supply everything for the kids to do this cool STEM project from Glowforge. However, the Resistor/LED block file was missing (staff is aware and have been trying to track it down so hopefully it will be there in the future). I decided to make a revamped version of the block and posted the file here in case anyone wants to use it.
The changes I made was to have the LED and resistor leads twist together and feed back through the acrylic (the GF version had them use copper tape pads and so this V2 cuts down some on the materials). I also added in the text for anode and cathode because I figure its a fun extra nugget of knowledge for the kiddos.
Nice. There are a bunch of those kinds of circuit module products on the market, but I love the idea of using the Glowforge to make your own. It always felt like the arbitrary limitations of what’s available in the kit would frustrate me if I tried to teach something with it.
Next step would to bring in velostat step sensors. That has always been a great communicator with students. It’s such a reactive material and I would love to bring it into a design like that.
I supported a KickStarter a while ago that was a metal sheet with magnetic components and a silver ink pen. I think it was called CircuitScribe. This device reminds me of that project.
At one point, they were working on inkjet cartridges but, I haven’t heard about any progress in awhile. Of course, you can stick the pens in a plotter.
Right. The ones cut in step 2… If you make that a “score” instead, you can’t do it. What I was saying is that “Cut” is correct for that step.
