  • You’ve piqued my curiosity… Care to share anything about the process you used for the silicone encapsulation and any lessons learned? Was it something done by a vendor, or is it a process that can be done in a home shop?

  • If you’re taking requests, I’d love to see you break down everything there is to know about wiring. There’s a Sparkfun tutorial on wire/connectors, but I feel like it just scratches the surface. I’d love to see a deep dive into: - What are the different types of wire available? Why should I use one over the other? Solid, stranded, different insulators, gauges, ribbon, bundles, etc… - Best practices for making your own wire bundles - Everything you ever wanted to know about heat shrink - Waterproofing and wiring - Choosing the correct gauge for a project… - How do I shop for multiple conductor wire? And where would one shop for that? - What kinds of connectors are out there, and how do you hook those up/crimp them on?

  • Thanks for the update on the barcode scanner. I’ll have to look into the behavior of the barcode scanner converted into serial mode to see if that would work for starting the project back up.

    The concept I was working on involved the tracking of barcoded physical items on designated, barcoded shelves. I wanted to prototype using a thermal printer and barcode scanner so a user could scan an item, scan the shelf and automate a placeholder printout/receipt that listed the user, date/time of the pull, and the barcode of the object that usually lives that physical space. Since there is no need for outside communication to attach any relevance or extra meaning to the digits of the barcode, I figured I shouldn’t need more than a basic Arduino to get it running… Yeah, there are probably commercial products that do exactly what I want to build, but where’s the fun in that?

  • It never crossed my mind that something like that would exist… Thanks for sharing!

  • A few months ago I was looking into barcode scanning and gave up because it looked like it was going to be a major pain to add that into the project… If you’re taking suggestions, I’d love to see you hook up the hardware of a barcode scanner into what you’ve got started here. Especially if that barcode scanner was doing more than just acting as a keyboard input over USB, and you could use that barcode data directly in an Arduino or Pi…

  • I have a deep respect for how open SF is as a company and I appreciate your response. I don’t want to see you guys narrow your focus to any specific topic, it was just jarring to go from a huggable plush project one day to vaping the next. I probably should have said ‘unusual’ in my original comment as opposed to ‘bizarre’- my bad on that.

  • Does anyone else find this a bizarre subject to have on the front page of SparkFun? With your emphasis on education, I was surprised to see you featuring this content. Is this the dawn of an edgier SparkFun?

  • Appreciated the narration. Looks like fun.

  • UV cameras seem to be conspicuous by their absenceā€¦

    I’m not an expert in the world of camera components, but I’d suspect the reason why I see more IR than UV cameras in embedded applications is because of the difference in optimal optics involved for UV vs IR… For IR, we can use the same optics/lenses as visible light- the only adjustment required is a filter swap and maybe focus (depending on the lens). For UV, regular optical glass does not transmit UV very well, so carefully chosen or modified lenses are required for the best results.

    I suspect it’s a lot easier to make an IR camera than a UV camera, which keeps UV in the niche of the niche.

  • What would you build if you had a jet engine?

    Personally, I’d probably build a safety enclosure.
