@Brian: You will have some on Friday (4/25) sometime between late morning and lunchtime.
Hi Brian, thanks so much for the horse and cow manure -- and please thank your sons Sam and Daniel for getting up early this morning to gather it for me (I get the impression that they's stopped asking questions when you say something like "Max" and "Cow Manure" in the same sentence LOL)
I will start my experiments first thing in the morning (after my realtor wife Gina has left for work LOL)
Re:bring it round to my office the next time you are passing
You will have some on Friday (4/25) sometime between late morning and lunchtime. We will bring a small amount of "material" from both cow and horse with the containers marked. The boys will be with me.
maybe you could work this one in (although I'm not sure how you could do the Steampunk look with it): Microview (an Arduino in a DIP package with OLED display - it looks really cute, but I'm passing because I don't have any immediate need for it and I have too many lonely dev kits).
@Brian: ...the field behind our house has cattle grazing on it. There is an endless supply of such material you speak of... :-)
Let me tell you where you can stick your cow manure .... in a plastic bag (just a couple of pounds -- say 5 pounds -- tripple wrapped) and bring it round to my office the next time you are passing -- i only need a small amount for my test pieces -- if this proves to be the best solution, I'll let you know how much more I need for the main panels.
The reason cow manure sounds like it might do the trick is that it's both acidic and salty and contains a lot of amonia -- all of which can be used to age brass.
@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!
@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?
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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
