In most of my last projects, I used nice miniature connectors from TE. This is, again, no sponsored post. If you ever evaluated connectors, you may know how overwhelming the range of products is. I like to introduce these connectors to you, in the hope you find them as useful as I do. 😅 I…

Tiny Particle Sensor Node with Decorative Case
This article is about a small sensor node with a decorative case. It is based on the Raspberry Pi Zero W board with a custom sensor shield. I publish all hardware files for a simple sensor version, so you should be able to build this kind of sensor node and use it to monitor anything…
Testing the TPS61092 Boost Converter
For my current project I searched for a good boost power converter which is able to deliver continuous 400mA power for various sensors. There are an endless number of good boost converters around, but not many can be hand soldered to a board. I would really like to see some like the TPS61092 with SOIC…
Boards in Good Quality from SeeedStudio Fusion
SeedStudio offered me a coupon to evaluate their PCB service “Fusion“. I am currently working on a new project, so I gave this service a try. I used the following options ordering the two boards: PCB Dimensions 68mm*108mm Impedance Control No Surface Finish HASL Lead Free Minimum Solder Mask Dam 0.4mm↑ Copper Weight 1oz. Plated…
Perfect Prototype Boards from Eurocircuits
Today prototype boards from Eurocircuits arrived. The quality of this boards is outstanding. I do not know any other board house which delivers this incredible quality of boards. They really thrive for perfection.
Plant Watering Sensor Foot Parts from Eurocircuits
I received the foot parts of the plant watering sensor from Eurocircuits. As you can see, they have the same great quality as the head parts. Eurocircuits removes any bridges from the boards in a very clean way, so you get the boards with exactly the shape you designed. This saves a lot of work…
Eurocircuits Delivered Astonishing Perfect Panels
I ordered a single panel as a test for the production version of the plant watering sensor and I got astonishing perfect panels from Eurocircuits. Even I only ordered just one, I got three perfect panels in gold. Thank you very much Eurocircuits! As you can see from the photos, the quality of the panels…
How to Design a Cheap Plant Watering Sensor (Part 5)
This is the fifth part of the meta-tutorial, where I talk about designing a cheap plant watering sensor. If you did not already read the first, second, third and fourth part, please do it now. These parts contain a lot information which lead to this point of the tutorial. The fourth part ended with step 20, where I did usability tests and stability…
A Versatile ATtiny Programming Adapter
As mentioned in my article about designing a cheap plant watering sensor, I built a small adapter which can be used to pre-program the ATtiny13A. This is necessary, because once soldered on the board, I only have a debugWire interface, which has to be enabled first. The adapter has a small 50mil JTAG header, where…
