Desoldering plate – pt1

Part 1 : why is it always broken when I need it?! A little while ago, I grabbed that kit online to build a desoldering plate meant to “demolish” LED strips from TVs. The idea is simple: an aluminum plate that heats up and you put your part on it so the solder melts and […]

Mastercraft industrial Shelves Hooks – pt3

Part 3 : Completion… Almost. I now have a proper system to anchor things to my shelve! It’s not glorious but it holds steady, looks pretty decent and I can pretty much customize it to get whatever I need hooked up. The new model only has one set of holes, which is plenty enough with […]

Repurposed 18650 Batteries into a power station – pt1.4

part 1.4 : cooling and completion! I finally finished to put together the tester and charger system! By itself it would probably deserve a project category on it own but I’m lazy and tired so for now, it is what it is. Last time I left off with a pretty usable system but it was […]

Repurposed 18650 Batteries into a power station – pt1.1

Part 1.1 : Getting the right tools for the job. Since I had these grandiose idea with limited tools, it was a bit long and difficult to do all the testing needed. So as my usual self, I ended up ordering the stuff I needed to make a proper charging and discharging station. The station […]

Mastercraft industrial Shelves Hooks – pt2

Part 2 : First Actual prototype My partner managed to resurrect one of our printer and we managed to get a first prototype of the support and honestly, it’s not perfect but i’m pretty darned happy with the first version. I already have a few things to “upgrade” on the model but I still am […]

Mastercraft industrial Shelves Hooks – pt1

Part 1 : The current situation, the problem & the plan (?) So, here’s the current situation, I have a few things hooked to the side of the shelve to hold them but, they have proven to not be great supports. I have made a lovely Desoldering pump holder but sadly, it doesn’t have any […]

Simple Wall-Mount Power Switch for rPi – pt2

Part 2 : Designing the box After a patient wait, I have finally received all the pieces I need to assemble design the box. I opted for a new approach this time. I normally model my contraptions in Blender as I have learned 3D modeling with this tool and STL files are 3D models, but […]
