How to Fly the P-47 Thunderbolt

In my opinion, the Republic P-47 Thunderbolt is one of the most amazing planes of WWII. Some time ago, I found some interesting videos on Youtube showing how to fly this plane:

Minipulse Plus Beach Pulse Induction Metal Detector

I have made some metal detectors, both VLF and PI. Until now, one of my favorite is the Minipulse Plus Beach as known as MPP Beach. It is a Pulse Induction detector specially designed to work in the beaches but you can tune it to use in many other situations, like finding Gold nuggets. If you are interested in the project, please check the Geotech Forums, in my opinio, the best forum about metal detectors: https://www.geotech1.com/forums/forum/projects/minipulse-plus/14902-mpp-beach-rev-e Below, are 2 videos I have testing the detector I've build, firt, with a Spider web coil and latelly with a simple mono coil with 3m shield tape. https://youtube.com/shorts/ksGzeMP_x0I?si=OkjFHkC09U5LKZKO The best result was found using the mono loop coil shielded with the 3M tape. If you have already made this detector, please share in the comments your results with it!

DIY mineral specimen storage box

There are several ways of storing rocks and minerals specimens. Some prefer to have them visible, other prefer to have them secured in boxes. Personally, I prefer to have them stored in a box, so they don't get dirty with dust, so I decided to build a simple wooden box. It is a simple rectangular box with small boxes inside like drawers that are pulled from top. Dimensions of the main box are 40cm length x 20cm wide x 25cm height. There is space for about 4 drawers inside. I have organized the smaller specimens into paper boxes, although the larger specimens are loose. You can see a small video of how it works to open and pull the inner drawers: https://www.youtube.com/shorts/LhDBVJ7s5Vk I have used this style of box to store minerals but I can be used for any other kind of collectible.

DIY sheet metal brake

One of my hobbies is to build electronics projects, like metal detectors for treasure hunting. Usually electronics boards are hold inside a plastic or metal box. There both in the market, but usually they are not so cheap. One solution I thought about, was to build my own boxes using aluminum sheet as it is a soft metal. Although aluminum is soft, for the thickness I want to use (2mm) it is not so easy to bend it by hand, so I searched a bit how to make a tool to bend the metal with the less effort possible and with good results at the end, I came up with this, using only 3 pieces of wood, 2 screws with bolts and 2 hinges: This is known as a sheet metal brake, mine is simple, made of pine wood but I recommend you to use harder woods, specially if you need to bend metals harder tha aluminum. I think you can replicate one easily just by looking at the pictures above, so I'm not provinding any measurements but if you need, please write a comment below. For different sizes or formats ...
