Cool Projects for Test, Measurement, and Control

The Raspberry Pi has dominated the maker scene for many years. Freely accessible I/O pins have made it one of the most popular processor boards of all time. However, the classic Raspberry Pi has no analog inputs. Direct measurement of analog values is therefore not possible. Consequently, photodiodes, NTCs, Hall sensors, etc. cannot be read directly. In addition, the pins are connected directly to the exposed contacts, i.e. without a driver or protection circuit. This can quickly destroy the central controller and thus the entire Raspberry Pi.

These problems can be elegantly solved with the Pico. As a front-end, it can easily handle a wide range of measurement tasks. In addition, the Pico is much cheaper than a classic Raspberry Pi 4 or 5. If a faulty circuit leads to the destruction of the Pico, this is relatively easy to handle. This makes the combination of a classic Raspberry Pi 4 or 5 and the Pico an ideal pair.

The book introduces the broad and highly topical field of modern controller technology using the combined force of a Raspberry Pi 4 or 5 and a Raspberry Pi Pico. In addition to a detailed introduction to the operation and functionality of the controller boards themselves, the book also focuses on data acquisition and processing with digital processors. Especially the combination of both systems offers a wide range of interesting possibilities.

Some practical projects from the contents:

  • USB between Raspberry Pi 4 or 5 and Pico
  • I²C Communication and Pico as an I²C device
  • Voltmeter and Computer Thermometer
  • Pico W as a Web Server and WLAN Scanner
  • Frequency Meters and Generators
  • OLED Displays on Raspberry Pi 4 or 5 and Pico
  • Energy Saving Monitor
  • Which Astronauts are in Orbit?
  • Mini Monitor for Current Bitcoin Exchange Rate

What an excellent wrist rest! Except for this one thing....
Color: Walnut Wood, Size: Large
This is a solid piece of wood with great quality. Fantastic large rubber grips on the bottom (left and right sides only). Pro: I use it for editing and gaming. And though I thought the wood might be a bad choice in the long run, it turns out it's pretty nice. Not as comfortable as a gel rest but I knew what I was getting when I ordered it. I buy things for function AND aesthetics. I love how this looks. The uniqueness is really something. I got the natural one instead of the black so that the grains and lines can be easily seen. Con: Unfortunately, after almost 2 months, the wood has warped some. Not enough to effect my typing but, enough that I notice it. The warp is the kind where the opposite angled corners go up and down. While the other 2 corners are fine. In my case, the top left and bottom right, when pressed independently, rock the wrist rest. The top right and bottom left stay grounded. This is why I took a star off. Because there's no way this should be happening. So, looks and quality are up there. The rubber grips are solid. Why it's warping is puzzling to me. NO liquid wasted on it. Or, extreme temperature changes have happened. I've made sure the rubber grips. And that the surface the rest sits on (a glass mouse scrolling top by Superglide) is clean. Yet, I get this slight rocking. It bugs me this all happened right after the return window closed. I would've simply exchanged it. I love it too much. I mean, this is, again, a SOLID piece of wood. Maybe this won't happen for everyone. I mean, it's wood. Eh I would still recommended this regardless.

Fantastic Product
Color: Walnut Wood, Size: Small
This is very nice! I type all day for my job and this made a big difference. It's very comfortable and supportive. Im allergic to latex rubber, which is in most gel options. It's really nice to have a safe, effective alternative

Beautiful, Solid Real Wood Wrist Rest
Color: Walnut Wood, Size: Large
This wooden wrist rest feels premium and the finish is super smooth — it’s noticeably nicer than foam or gel pads. Real wood looks great on my desk and still feels comfortable during long typing sessions. Definitely worth it if you want something stylish and functional.

Amazing item!
Color: Brown
Amazing quality feels very nice to the touch, decent size, on the bigger side if you’re looking for a smaller table organizer, but still great!
