Parts parts parts Starting things simple I wanted to try the concept and get a feel for the feasibility. This setup consists of one T-junction of 10mm diameter plastic piping, normally used for plumbing.Holding the plant (cauliflower) is a 3D printed...
Bugfixes3.3V regulator added so the SD card isn’t supplied by the reference output of the USB-Serial bridge.Unused inputs on SD card buffer IC are grounded. Stock design leaves them floating.PCB layout fixed to follow standard PCB design guidelines including...
The TSL2591 gives a read-out of light intensity in lux. For those numbers to be numerically accurate, the device should be calibrated under lab conditions. Luckily, I wasn't as interested in the accuracy and precision of the values as I was in distinguishing...
A couple of weeks ago, readings from the light sensor went crazy. Starting at a certain point, the only two values ever reported were 0 and 64k. The latter (actually 0xFFFF) indicates saturation of the sensor. That was very bad for the use case, so I...
For start, I will solder pins to LILYGO board and sensors. Once I saw sensor readings are working I've decided to transfer all this to perfboard, add all sensors that I mentioned before in this tutorial and let's connect everything to work as we want....
I've built several clocks (see other projects including a NeoPixel ring clock and a couple of RGB matrix based clocks that have animation and Westminster Chimes, cuckoo clock sounds and/or simple tolling bell. All these use an Arduino...
The Approximate Library makes it easy to identify a close by device and then watch its traffic. In this video the ESP32 reads the Google Home's MAC and IP addresses; with this information it forms a pair and the LED now flashes to show the network traffic....
While the #Tote robot was close to what I wanted to achieve back then, it had two major problems. First, the servos, even though relatively cheap individually, contribute to the total cost of the project considerably, because you need at least a...
RYC1001 from Reyax is a cloud platform suitable for low-data-volume and power-saving devices. Using the MQTT protocol, you can use simple commands for your applications, monitor end devices, and easily establish your IoT connection. It can be used as...
I am going to use the Tuya IoT platform to develop a smart device from scratch. The simplicity and fast response time of the Tuya IoT cloud are amazing, all you need to do is set up function definitions, design app panel, and burn authorization firmware,...
My goal is to make a Solar-powered wireless weather station by using an ESP32 Wifi Module and few common weather sensors available in the market. The weather station will be fully solar-powered, so no need to worry about the external power supply....
[Images and videos missing, will update later]Dial Holder/ Homing Switch Version 1 Originally designed to fit a nema 17 stepper motor shaft. The holes around the dial adapter are for M3 screws to tighten around the dial and the inner black ring was printed...
Here are the ideas that my preliminary research has yielded:Main formatThere will be a control box at the bottom of a long strip of LEDs. This box will have a single toggle switch, an led indicator for that switch, a servo to reset the switch,...
Before presenting the boards, I will set down my goals for this project. Non-goals are to make the thermometer work again, or even to reuse the logic chips, the equipment is long obsolete. Thus my interloper UART board previously pictured has been removed...
