@David: Those are pretty tasty..... only a buck each too....
I'm really enjoying playing with Adafruit's NeoPixels -- I'm using the rings and the strips and the Flora NeoPixels at the moment, but I'm sure I'll find a use for these through-hole ones in the fullness of time.
@LukeMiller: I love this... how did you get the panels cut?
David -- the master machinist guy mentioned in the blog -- has a friend who has a water jet cutter; that's what was used to cut everything out. Willie -- the guy who created the 3D drawings for me also output the CNC files required to drive the water cutter. They do look tasty, don't they?
@Max: I dream of having a proper workshop. If I had the money, I'd build something at the bottom of our back garden and equip it with all sorts of woodworking and metalworking tools. It would be wonderful to be able to spread out over multiple worktables and have things like circular saws and suchlike all set up and poised for action.
You get access to a bunch of tools, plus you can have your own private workspace too. I joined the one here in Birmingham, and it's been a blast (sometimes literally!). I like working on a project while there are people around who have expertise in other disciplines. It's nice being able to get tips from a machininst, a welder, a Linux guru, and a ceramics expert- all without leaving the room!
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
