I make my almond milk with creamy almond butter - no straining necessary.
amazing! I own the real thing, bought at a deep discount when the electronic scientific calculators from HP and TI came out. In some technically oriented schools students learned to operate the levers of these marvelous devices rapidly with their thumbs - like people using smartphones today.
Ingenious - how long does the battery last? (The external circuit has very low resistance; thus a high current is flowing, discharging the battery rapidly.)Keep the magnets away from small children, who might swallow them!
Go to a place where they recycle electronic equipment and look for two UPS. They contain transformers you can connect back to back, with lot of power if you find big ones.
While you get three times the voltage, which is not surprising if you understand how solar panels work, it's the power in watts, voltage times amperes, which is of interest, just look at your electricity bill. On commercial solar installations, there is an inverter which optimizes the watts by adjusting the loading on the array. In your case you have to find the optimum power manually by adjusting a load resistor. The angle with which the sun shines on a solar array changes in the course of a day. For example I get 2.4kW at 12PM, 1kW at 5PM for my rooftop array. Your proposed arrangement of the panels is at a significant disadvantage in this respect, unless you install an automatic mechanical gizmo to track the sun.
I built something similar for my Mazda5 minivan. I built a platform by fitting a plywood sheet to the interior shape of the car, cut in half, with hinges across the middle. The second row seat is removed, and the front part of the platform rests on 6 milk creates with camping stuff. The crates are sturdy and easy to carry from the car to the camp site.
When measuring current, the current flows through a resistor inside of the multimeter, and the instrument actually measures the voltage across, which is proportional to the current. The internal resistance should be small, in order to have a small influence on the behaviour of the circuit which you want to measure. Consider that some auto-ranging meters have a relatively high resistance, with voltages across the instrument terminals approaching 1V at full scale.When measuring small resistance, on the order of 1Ohm, consider the resistance of the probes. Short the tips to read the resistance of the leads, and subtract this value from the one displayed when connected to the resistor under test.
