X700 INSTALLATION OF A MILLIAMPEREMETER

I have been wanting to install a milliamperemeter in my lasercutter/engraver for some time. The reason for this is that i haven’t been able to make the lasertubes last as long as they are advertised. I recently  purchased a Reci 100W tube, and this time i want it to last as long as possible. Here is a link to the tube i ordered. The life span can reach 10,000 hours if the current is kept below 26mA. Here is the analogue...

DIY POKEMON POKEBALL

My son really wanted a pokeball for his 11th birthday so i decided to make one for him. I had a switch lying around that would be perfect for this project so i designed the ball around that. First i designed the pokeball in 3Ds Max Then i printed it with the Formlabs Form 2 3D printer After removing the support material, i sanded the 2 pieces pretty smooth. Here i did a test fitting of the switch. Fits perfectly I then glued into...

SAMSUNG CHARGING STATION

I wanted to have a charging station for both my phone and smart watch. This project was just a small project, but ended up to be one of my favourites as it works exactly how i intended it to work. I printed it on the Form 1+ 3D printer, but because of the size of the design i had to print it in two parts and glue it back toghether. The charger for the smart watch (Galaxy Gear S) had a tab on the side that i had to dremel of to get it...

WATER SENSOR

This is a simple sensor for detecting water. This is a project that i made for someone at work, that needed a water-sensor for detecting leaks from washing machines. This is a portable battery powered device that is easily put on the floor in front of the machine in the usual path of running water (The floor has a slight tilt). The sensor itself is made up of two paralell wires and a 1 Mohm resistor, so when water comes between the...

FOOLPROOF 3D PRINTER

FDM 3D printers are notorius at failing during big prints, and there is nothing worse than printing for 10+ hours just having to start over. So i started thinking about solutions to fix this problem. The most common problems is fillament getting stuck in the spool, and blocking in the extruder. So i had to come up with a solution to remedy those two problems. The idea: Make the fillament go trough a gear that rotates with teeth...
