To demonstrate that the calibration was successful, we recorded a video and collected photoresistor readings while arbitrarily extending, retracting, and twisting the telescoping pole. The plot shares the output from the two photoresistors over time....
The wind sensors, Arduino and EMT conduit telescoping mounting pole took measurements outdoors for about 90 seconds. The raw data, and processed wind speed and wind direction data are presented below. The method for converting from the raw Arduino readings...
This is the quick hack of another code sample "Register writer" to play a warm up sound. The hardware is based on the schematic linked in the code. Works with Arduino Uno R3 aka: 328 compatible boards. https://pastebin.com/raw/FehmVLQS /*******************************************************************...
Let’s get to it! Install Arduino IDE, the esp32 board and the Fixed Libraries. To install the ESP32 board in your Arduino IDE, follow these next instructions: 1) Open the preferences window from the Arduino IDE. Go to File> Preferences 2) Enter https://dl.espressif.com/dl/package_esp32_index.json into...
I used micropython, because I haven't used it for a project yet and I was shocked how well it worked for this. There are many tutorials on how to use Thonny with an ESP32, and I found it to be much quicker than doing this in Arduino/ C++. The main files...
Step 3: Connect to VivaPlanetThis next step is a bit more complex and requires some C# and visual studio with the Gagetter software from GHI Installed. This will take some time...persist it will be worth it in the end...There are a lot of great tutorials...
Take the new polarizer film and slide it behind the LCD. If you turn the polarizer one way, the screen will be transparrent. If you turn it the other way, the screen will be opaque. Behold the magic of polarized light!Now you have the option of inverting...
VLC:Live transcoding is resource intensive, making it nice to be able to turn it on and off. Also switching the VLC configurations allows for many variations of size and quality, useful in tailor the stream to different devices and scenarios. Below are...

1) Come up with a simple good idea.2) Add good ideas to it.3) Try to implement it.4) When it fails, start to strip down the design to try to get it to work.5) Strip it down more6) More...7) Rejoyce when something simple works8) Add a few simple things...
