UV Curing Lamp for DIY PCB Solder Mask

UV_Curing_In ActionOne of the downsides of home-made CNC printed circuit boards is that a lot of the copper cladding remains and can lead to short circuits when solder strays onto the common waste area outside the formed tracks. Also, after a while it tarnishes and does not look great.

One solution to both these problems is to apply a solder mask over everything that is not meant to have solder on it, similar to professionally made boards.

Finding Zero

Finding_ZeroAnyone who uses a CNC machine eventually realizes the importance of the Zero point. This usually happens when something goes wrong during a machining cycle, the machine needs to be reset and the current zero is lost. Fruitlessly searching for a lost zero prompted me to develop a repeatable process for finding the same zero time after time. Here’s how I do it.

Big Button Remote Control – Part 4 – Completion

Umote Completed 2With all the preparations completed, Umote can finally take shape for this application. The final product can be broken down into four major subsystems that need to be made and integrated in their final form – IR interface hardware, Enclosure, Power Supply, and Switches and Control Wiring.

Haberdasher’s Puzzle

Haberdasher puzzle squareThe Haberdasher’s puzzle is a simple 4 piece puzzle whose parts can be assembled into a square or an equilateral triangle. Solving the puzzle is easy, but for me the beauty is in the geometric dissection used to make the parts.

A long time ago I made one of these using a ruler and compass. Now I have a CNC, I was interested to see how well a CAD drawn and machine cut set could fit together.

ShapeOko Working Light

CNC Light onWhen machining using the ShapeOko I find that I often needed to use a torch to more clearly see what is happening the cutting area. So I decided to create a permanent LED installation with a remote switch to solve the problem.

Project Front Panel

Faceplate mock-upMy electronics based projects most often end up in a box of some sort. with related knobs, LEDs or displays showing on a front panel. Over the years I have tried a number of different ways to make these panels look nice, and I think I have finally found a method that looks professional and I am happy with.

ShapeOko/TinyG Limit Switches

Limit Switch HolderI really wanted to add limit switches to my ShapeOko2 CNC, so I did some research and eventually decided that I needed to come up with my own design.
