Im sure the burn-in is not a problem on this clock. You will only see it when its turned off, so just keep it on ;) Surely you wont notice if the digits are even 50% burned in. They will just shine less than when it was brand new.
Another much cooler option is to make the static stuff dynamic. Why not make the digits come to life? Make them jump,tilt,grow/shrink a bit. Make it stand out when the arms hit it. I could go on..
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.
