How do you measure a measuring device? Let’s say you have a digital caliper, and you want to make a case/enclosure for it to hang it on a pegboard. You could buy another digital caliper. Or you could try to 3d scan it using photogrammetry or you could use a fancy Xbox Kinect to scan it. Then you could import the model into the CAD software of your choice and design the fitting accordingly.
Helder Eiki of a 3d printing useful things Facebook group had a different idea: He scanned his digital caliper using a photocopier in A4 size and imported the image into Fusion360 to model his enclosure. And as the saying goes: Genius is in the simplicity

My wife had bought a calendar wall hanging for the house last year. It is one of those old split-flap displays where each flap rotates to show the date. Most people would just drill a screw into the wall and hang it or maybe use a double-sided tape and stick it into the wall. That may be simple, but not a genius.
Since the calendar base is made of metal, I decided that I would hang it using magnets. Hence, I 3d printed an auxiliary base plate that holds neodymium magnets. I taped it on to the small door of my houses main electrical fuse box. Then I mounted the calender onto it which now perfectly hides the electrical fuse box of the mains supply completely while also providing me the access to the mains switch just by pulling the hanging calendar out of the way.
Come to think of it: I did not care about hiding the fuse box door. I could have just hung it anywhere but sometimes genius may just not lie in the simplicity.

A camper is born by Aqeel ⚒ Arshad, Arfan and Habib
Campervans are a type of vehicle, which provides both transportation, and all the basic facilitates that one would need to spend a few days outside in nature. In reality a camper van in nothing but a normal delivery van fitted by the manufacturer with facilities such as bed and kitchen. So we kept it simple and decided to buy a 9-year-old delivery van to convert. Starting this post, I am going to share the experience of hacking the van. As a first, our hack around fitting a bed.
Once the backseat was removed, we decided to buy a simple sofa-cum-bed put it inside the van. Only problem: it was not high enough to fit due to raised body at rear wheels. The solution was Genius: We just raised the bed.
For now, We are off to the Dolomites. I will be sharing more hacks to the van in the future editions and my full write up here.

Speaking of things keeping simple, Nishant Singh is not a big fan. He has contributed in previous editions by sharing his 3d printed moonlight. He decided to put Bluetooth audio capability in his moonlight to make it not only look romantic but also sound like one. Nishant in his writeup shares how he has managed to use his decoupling caps to use overpowered (2 Watt speakers) with underpowered supply (1.25 Watt USB supply). He shares his component list and circuit in his write up. You can check out his write up here and suggest improvements.
