So, in this function, we first enable the peripheral clock for GPIOA. This is because we are using pin PA5 to act as an output channel for timer 2, specifically to act as TIM2_CH1. In order for pin PA5 to act as a channel output, we must configure the pin to...
Experimental procedure to control microscopic wrinkles in PSC is schematically illustrated in Fig.1a. The perovskite precursor solution is first spin-coated on a solid substrate for 20 s, followed by dripping DE 10 s right after spinning. The cross-sectional profile of the microscopic wrinkles ...
Next, the compressor, if it is a PSC motor, and the blower and condenser motors, if they are also PSC, undergo “inrush current” every time they start. Sure, the windings can handle this. The contact points on the contactor can also handle it. But, regarding the latter, a penalty k...
While I wait for all my components to arrive to finally be able to get first light on the little Takahashi Epsilon, I realized I don't really know how to add a focuser motor to the stock focuser. I have at my disposal a Pegasus FocusCube V2 or a ZWO EAF, I have mounted these foc...

air flow. Study #2 looked at this issue.) The rule we use in ourHVAC design work at Energy Vanguardis to size the filter at2 square feet of face area for each 400 cubic feet per minute (cfm) of air flow through the filter. That results in a face velocity of 200 feet per minute....
Gm is a bunch of JUNK. Reply Michael Dixon says: August 29, 2019 at 6:48 pm Yes that’s true. But the problem at that time was the computer technology. The computers had not evolved enough to control the sytem. Todays computers are faster so it does work. But if you ...
