This post will be a walk-through on how to install SMATH on Ubuntu 22.04 through WINE – however I think it should work on other distros as well. If so please leave a comment regarding the outcome.
Sensor Data on WordPress – Practical data monitoring with a cost-effective Raspberry Pi website
The Raspberry Pi is something of a Swiss army knife, the enormous amount of applications it has been used is mind-boggling. It is simple math – make a certain technology wildly versatile, make it cheap and accessible for the masses and soon enough there will be a lot of good ideas in circulation. One of the many things you can check in the Raspberry Pi without the need of additional gear is to read the CPU temperature.
This website is hosted by a headless Raspberry Pi working away in the cold depths of my tool shed. This post will be about how to display sensor data on WordPress collected by the Raspberry Pi, such as the CPU temperature, in the “Google Charts” gauge as you can see below.
Running ‘vcgencmd measure_temp’ in my headless Raspberry Pi terminal (which also hosts this very website you’re currently reading) yields “temp=45.1°C” which is the current temperature of the processor. This is good since the shut-down limit is 85°C and the throttle-down from 1.4GHz to 1.2GHz (soft-limit) happens already at 60°C which is easily achieved in room-temperatures. Keeping up the performance is good no matter what you decide to do, for example running retropie or maybe hosting a web server even though I doubt that the CPU utilization would peak very often.

ATtiny85 – Wield the power of the mighty ATtiny through Arduino in 8 simple steps
In this post I will show how to connect and program the ATtiny85 using the Arduino Uno and Arduino IDE. The ATtiny85 is small but packs a serious punch. If the project-scope allows, it is a good alternative to its bigger sibling ATmega328p. Obviously it does not have as many pins and lacks the 16 bit timer but in many cases it can be more than enough.
Raspberry Pi Web Server – Become accessible in the world stage
What you are reading now is hosted by a headless Raspberry Pi web server. It is a cheap card-sized computer run on a 5V 2.5A power supply located in the cold depths of my tool shed close to the arctic circle. Used as a web server the average power consumption is probably less than 10 Watts.
Headless Raspberry Pi Setup – The easy 4 step approach
A headless Raspberry Pi is a Raspberry Pi connected to the LAN without the use of peripherals such as keyboard, mouse or a monitor. This is the only way I have ever used a Raspberry Pi with the exception of my retropie console.
Upgrade with Arduino Uno – A Fun way to recycle a toy car
So one day my daughter, which at the time was a couple of months short of 3 years old, caught sight on a learn-to-walk car which she wanted badly. It was neither expensive nor specially advanced and definitely intended for children below her age-group.
