Responding to the Rethink Shows problem of the 2021 Hackaday Prize contest, freelance design engineer [Rick Pannen] brings a retro look to his DIY house automation controller. You might be forgiven for not even realizing it’s a controller at first look. [Rick] constructed this utilizing a magnetic chalk board and put in all of the management electronics on the again. The principle processor is a Raspberry Pi 400 operating Raspian with IOBroker and Node-Purple. Panel lettering and graphics are executed free-hand with, you guessed it, chalk.
The controls on this panel are an eclectic hodgepodge of meters, switches, and sensors that [Rick] scored on eBay or scavenged from pals. We’re curious in regards to the simple-looking rotary dial that sends a pulse practice primarily based on the quantity set on the dial — this appears to have all of the performance of an outdated cellphone’s rotary dial with none of the enjoyable.
However [Rick]’s design permits for straightforward modifications — dare we are saying, it encourages them — so possibly we’ll see a salvaged rotary dial added in future revisions. Additionally observe the indoor lighting ON/OFF change that have to be an actual pleasure to function. We surprise, is there any approach the controls could possibly be magnetized and moved freely across the board with out completely attaching them? Perhaps an concept for model 4 or 5.
This design has quite a lot of prospects, and we sit up for any upgrades or spinoff variations of this distinctive house automation controller. Tell us within the feedback beneath if in case you have any ideas for increasing upon this concept.
