Here is a draft of my instructable for my final project. I will update it as I determine how everything goes together!
This is my first instructable and I hope to create many more in the future. I was originally looking for a softer, less abrupt notification system than a vibration, sound, or light based notice. As I am also interested in clocks and adjusting the way we think about time, I wanted to incorporate this into my solution.
I came up with the idea of using a bubble in a container of liquid to first notify me of some event and then use the time it takes for the bubble to rise to provide a sense of urgency to how I should respond to that event. An example would be a message from a boss or important contact. The bubble would form and then rise at a rate that would give you enough time to respond before it pops at the top.
I’ll try to simplify the steps as much as possible so you can replicate this project at home but there is definitely some experimentation involved in getting it to work for you.
- Procure all the equipment and supplies
-Nano Air S1 pump
-Clippard ET-2-6 normally closed, 6VDC electronic valve (http://www.clippard.com/part/ET-2-6)
-8ft Airline tubing
-Airline check valve
-Adafruit Huzzah ESP8266
-9VDC Power Adapter
-Glass VOSS Still Water Bottle
- Prepare water tank
I struggled to purchase the glass VOSS water bottle as most locations around me in NYC only sold the smaller plastic versions. I finally found them at Fairway. I bought the still water version because the cap was flatter than the sparkling water version.
Begin by scraping off the labeling using an Exacto blade. If you use the side of the blade instead of the tip, the process works a bit easier. I’ve been told that you can use acetone as well but I’m not sure it will cloud the glass at all. Give it a try and let me know!
After the bottle is clean, drill a ¼” hole through the center of the lid.
- Setup the air delivery system
Cut 3 lengths of tubing to the following lengths:
Connect one length of tubing from the pump to the reservoir inlet and another tube from the reservoir outlet to the solenoid. The last tube will connect from the solenoid outlet to the bottom of our water tank but we will do this step last.
- Build the base
Find a couple scraps of plywood and cut out the following pieces:
Next, cut a 1/16” thick sheet of acrylic into the following pieces:
- Wire together the electronics
Servo to board
Pump to relay to board
- Program the Huzzah board
Sign up for an adrafruit.io account
- Put it all together
Place the electronics and air system into the base and feed the outlet tube from the tank cap through the acrylic cover to the outlet on the solenoid. After the tube is firmly attached, place the acrylic cover over the bottom compartment and secure with the 4 screws.
Next fill up the tank with the TK liquid and screw on the cap. Turnover and place the sealed tank into the base. Flip on the bottom switch and make sure the power indicator LED is lit. Then send a test to the device and make sure everything works correctly.
That’s it! I hope you enjoy and that everything works well for you. If you have any questions or changes that can be made to this setup, please post them below as I’d love to hear them! Thanks for stopping by.
