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.
I published another small command-line tool for Raspberry-Pi. This time one to read data from the Sensirion SGP30 sensor. While you can communicate over I2C with sensors using Python, I found it not as reliable ... Read More
I just updated the flat boxes set. All existing boxes got a new revision, with an even better wall profile and there are five additional boxes in this set. Improved Wall Profile If you compare ... Read More
I tried something new with parametric design. 😄 Today I publish the first batch of heart decorated boxes for 3D-print in 500 different sizes. The sizes start from 35mm up to 120mm in small steps, ... Read More
