My brother and dad came over to spend a day trying out some of the ideas we talk about. We worked on turning stepper motors into miniature vertical windmills, completed Fogponic Grow Box V2, and made an electromagnetic motor.
The Fogponic Grow Box is an automated, self contained, plant ecosystem. The Grow Box is a fogponic plant box within a humidity and temperature monitored box. The underside of the top lid has strips of LEDs in both blue and red to promote root growth and some flowering effects. The box should require low amounts of additional sun light and minimally impact the surrounding environment.
The grow system suspends mesh plastic pots so roots can reach mist generated by an ultrasonic mister sitting a few inches below water mixed with hydroponic grow solution. Timers turn everything on and off. Initial tests average around a $1.00 a month to run the system in bursts 24 hours a day.
We’re testing sprouting four pots of kale in the system now.
We’re putting together a low voltage vertical windmill out of some parts laying around. We laser cut wooden wheels that can be stacked and bolted together.
We mounted a laser cut wheel on a bearing and positioned high power magnets around the outside edge. By placing a reed switch by the magnet wheel, an electromagnet pulses to push the wheel forward. 6 DC volts gets the wheel spinning fast.
We took the front off of our old family projection TV, mounted it on a frame, and used the power of the sun to smelt a stack of pennies together. The pennies melted in minutes in the afternoon sun. While burning everything we could get our hands on, we discussed the use of the lens for hot water and steam powered applications.
