Arduino or Wemos Code
Instructions from WiFi Signal Strength Scanner Monitor or Checker
In the arduino code set your WiFi credentials char wifissid[] = "ENTER YOUR WiFi SSID HERE"; char wifipass[] = "ENTER YOUR WiFi PASSWORD HERE"; Normally, the signal strength is displayed in dBm. But for a non techie person, the signal strength in terms...

Some notes
Instructions from Hydroponics Sensor
The ESP-32 board pins operate in 3.3v levels while the Gravity pH and EC sensors operate in 5V. I inserted a simple voltage divider to shift 5v to 3.3v levels on the signal pins.

Step 1: 3D printing
Instructions from UltraTower
To build a tower you will need to print the 3D parts shown on the left of the image. The "Sensors float" part is optional, print it if you want to use the pH and EC sensors. You will need 12 times the part: "Basket". You can download the files...

Redtree Hydra: A modular platform for robotics
Instructions from Redtree Hydra: A modular platform for robotics
Attaching a SensorIn order to attach a sensor, motor, camera or other component to the Redtree Hydra, the FPGA inside must be programmed. We know that this is normally a tricky task, so we created a tool to simplify it. The Redtree Hydra has four I/O...

Aeroponic All-year Greenhouse on a Budged
Instructions from Aeroponic All-year Greenhouse on a Budged
Next we will prepare the water flow. I decided to use this combination of pump and tubing, because they fit without an adapter. Other combinations work also. Clear tubbing isnt the best solution, because algae will grow inside the tubes. you can prevent...

Ultraviolet Lightsaber. Kill COVID-19 with Style.
Instructions from Ultraviolet Lightsaber. Kill COVID-19 with Style.
UV-C bulbs use a dab of mercury plus a glowing hot filliment in a low pressure tube of glass to generate ultraviolet light that peaks around 253.7 nano meters, the optimal germicidal wavelength in the UV-C part of the spectrum. Not to be...
