Some tools are so common, so basic, that we take them for granted. A perfect example is the lowly tape measure. We’ve probably all got a few of these kicking around the lab, and they aren’t exactly the kind of thing you give a lot of thought to when you’re using them. But while most of us might not give our tape measure a second thought, [Ariel Yahni] decided to create an absolutely gorgeous new enclosure for his. Because if you’re going to measure something, why not look good doing it?
A CNC router is used to carve the body of the new tape measure out of a solid block of wood and cut a top plate out of clear acrylic. [Ariel] then used an angle grinder to cut off a small section of steel rod which he secured into a carved pocket in the base using epoxy. Finally, the internals of a commercial tape measure were inserted into this new enclosure, and the acrylic top was screwed down into place.
[Ariel] has made the DXF files for this project public for anyone else who wants to carve out their own heirloom tape measure, though it seems likely the designs will need some tweaking depending on the make and model of donor tape measure. While this might not be the most technically impressive project to run on Hackaday, it’s still a fantastic example of the sort of bespoke designs that are made possible with modern manufacturing methods.
This design reminds us of a similar project to turn a basic Honda key fob into a true conversation piece with the addition of some CNC’d hardwood and aluminum.

It all started with a bad smell coming from the heat register. [CuddleBurrito] recalled a time when something stinky ended up in the ductwork of his folks’ house which ended up costing them big bucks to explore. The hacker mindset shies away from those expenditures and toward literally rolling your own solution to investigating the funk. In the process [CuddleBurrito] takes us on a journey into the bowels of his house.

Radio direction finding and fox hunting can be great fun and is a popular activity with amateur radio (ham radio) enthusiasts. These antennas are great and are not only good for finding transmitters but also will greatly increase directional distance performance including communicating with satellites and the international space station (ISS).
[jcoman] had a nephew who was interested in learning about amateur radio so [jcoman] figured building and using a cheap and portable 2 meter band VHF Yagi style beam antenna would be the perfect activity to captivate the young lad’s interest in the hobby.
His design is based on [Joe Leggio’s] (WB2HOL) design with some of his own calculated alterations. We have seen DIY Yagi antenna designs before but what makes this construction so interesting is that the elements come together using bits of cut metal tape measure sections. These tape measure sections allow the Yagi antenna, which is normally a large and cumbersome device, to be easily stowed in a vehicle or backpack. When the antenna is needed, the tape measure sections naturally unfold and function extremely well with a 7 dB directional gain and can be adjusted to get a 1:1 SWR at any desired 2 m frequency.
The other unique feature is that the antenna can be constructed for under $20 if you actually purchase the materials. The cost would be even less if you salvage an old tape measure. You might even have the PVC pipes, hose clamps and wire lying around making the construction nearly free.
We were quite surprised to find that such a popular antenna construction method using tape measure elements had not yet been featured on Hackaday. For completeness this is not the only DIY tape measure Yagi on Instructables so also check out [FN64’s] 2 m band “Radio Direction Finding Antenna for VHF” and [manuka’s] 70 cm band “433 MHz tape measure UHF antenna” postings. The other Yagi antenna designs featured on Hackaday were “Building a Yagi Uda Antenna” and “Turning an Easter Egg Hunt into a Fox Hunt” but these designs were not so simple to construct nor as cleverly portable.
