Hi David, To give an Idea of the size of the small boxes, a pound coin (euro) will just fit on the lid, the depth is about a pound coin deep. The lids flip up when opened and they are just great for smd resistors and capacitors.
I got my first set when I bought an E25 run of SMD capacitors and since then I buy them for any smd items.
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.
