Today the stencils from OSH Stencils arrived for the Swiss precision timer project.
I used to work with steel stencils for all my previous projects, therefore the polyimide film (3mil) ones feel very flimsy to me. I will see how they will perform adding the solder paste.
The cost of the two stencils, without shipping, was $14.05. For $15 I get steel stencils from PCBWay – but I did not test their stencil service yet. Eurocircuits would have produced steel stencils for approximate $50 in perfect quality.
In the next weeks, I will build and test the first prototype using these stencils. I am looking forward to how they will perform.
This design is not for everyone. 😅 A decorative and modular, but quite massive box. Built from 3d-printed parts, 5mm plywood panels and plenty 3x10mm wood screws. The instructions in this post show a basic ... Read More
I worked on testing the sensor board. The first tests I did were about the position sensor. Recap Let me recap the design of the position sensor in the device: The turntable has five position ... Read More
For various sensors, attached to Raspberry-Pi computers, I wrote small command-line tools to read the sensor values over the I2C connection. While you can do this with a Python script directly, I found using a ... Read More
After successfully embedding magnets, I started experimenting embedding whole PCB boards into prints. I am sure, this is no new idea, but I found it very interesting. From the outside, the printed object looks solid ... Read More
