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.

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...

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...

The sun-tracking system: to have the parabol always facing the sun
Instructions from The Sun Heater
The sun tracking system consists of: 1. Two roller shutter/awning motors: These motors are industrial, easy to purchase, cheap, and with a high torque (10Nm being the lowest). Average price of each motor around 30€...

Understanding how to disconnect the speaker
Instructions from Hush Owlet
moThe big black device in the middle of the printed circuit board (PCB) is the speaker (aka buzzer, or transducer). You can see a little slit in the one side where the sound comes out. There is a back side to the circuit board that you cannot easily...

Trying out GATTTOOL
Instructions from Reading a bunch of BLE sensors with raspberryZero
Now that i know how to access and decode the data lets try the Raspi GATTTOOL default BLE handler:Native to Debian and a lso to a bunch of linux distros or so i've heard of . First i reset the bluetooth of the raspi, just in case: sudo service bluetooth...

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...

Cree Dimming Level
Instructions from Cree Dimming Level
Flash the Arduino with the following sketch. This is also included as a file attached to the project. int last_level = 0; bool last_state = false; bool stable = false; int count = 0; const int cutoffs[198] = {/* 1*/ 833, 831, /* 2*/ 825, 823, /* 3*/...

Attach pedal and buttons to arduino.
Instructions from Racing game
Use the negative points of the button and connect to the gnd pin of the arduino.Use the positive pin of the button to analog pins A3 and A4.Use the positive pin of the pedal to analog pin A2.

Hacking a MG92b : Protect control bard
Instructions from Smarter Micro Servo (SMS) MOD
Use a a piece of heat-shrink sleeve as an envelop, or print a small 3D case to protect the control board.

AM2XBee4RC
Instructions from AM2XBee4RC
Mount your hardware and solder the appropriate wires from your ADC pads, GPIO pads and other components together. Each build will most certainly be unique so use your discretion as to which component attaches to which Arduino pin. I used the following...

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...
