Yes I have and here are a few links for you.

Link to the Mini Tower of RPi-Zeros.

> Just finished building a couple of mini-towers for my IoT Club. The idea is the towers can be kept in a cupboard at school and just brought out when I run the IoT Club. All I would need to do is plug the 6-port PSU into the mains and switch-on the Club's WiFi router. Should save a lot of time as previously I had to cobble together a number of Raspberry Pi(es),of various vintages, and then at the end of the session take the whole lot apart!!!

A previous tower I built at home using old RPi-2Bs and 3Bs.

> I've just built a mini-tower for some of my old RPi-3s and 2s and thought I would try out SVG to overlay some LEDs (as circles) on top of a photo to show LED status, and some text to indicate the CPU temperature and IP address. With Bart's @BartButenaers and Steve's @Steve-Mcl help I've managed to get a Node-RED flow and dashboard up-and-running. Thanks guys. A word of warning... Bart/Steve's SVG node is highly ADDICTIVE and so much fun. I've just discovered the 'Event' facility. As a test I'…

Pulse Width Modulation controlling a model racing car

> I make no excuse at all - this is just pure fun. My students will love it !!!! I've just bought a slot car racing set from a local charity shop and have connected it to a WeMos D1 Mini on a breadboard driven from Node-RED via MQTT. On the breadboard is a PCA9685 (16-channel, 12-bit PWM module). It took some time sorting out the best PWM frequency and range settings, but eventually settled on 1500Hz with a range also of 1500. The car goes from a slow "creep" to just below "max speed", as at …

Plane Spotting - no hardware at all, just nodes in a flow.

> Just been working on a "fun" project for my IoT students. It makes use of the 'flightradar24' and 'worldmap' nodes to display aircraft movements. It also uses an iFrame with Start and Stop actions in a simple dashboard. Here's a link to the tutorial guide and 'json' flow.
