Reusing a laptop monitor ends up being a financial wash. You have to purchase a driver board for it, since most have the driver integrated into the motherboard. Often, those driverboards end up costing the same as a more modern and possibly higher quality LCD.
That's a nice RasPi case. My only concern is heat: that's a RasPi Model B with a rev 1.0 PC board. Because of a design oversight corrected in the rev 2.0 PCB, the USB/LAN chip on some of those rev 1.0 boards overheat. In an enclosed case inside a warm PC, you could easily have overheating problems if there's a lot of Ethernet activity.
This only occurs with some rev 1.0 units. You can get heat sinks for the RasPi SoC and USB/LAN chips, which helps.
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.
