Electric Blinds for under $10

My sub $10 electric blinds. Made with simple electric screwdriver and DPDT switches. Changed voltage from 6v to 9v for added speed.

Electric OU: More on Oscillations: Relationship of FG Drive Offset to MOSFET Switching

Or: Why a simple 555 timer cannot produce all the effects of the Ainslie circuit. The complete circuit schematic is available for download here: www.mediafire.com For the negative gate drive, low heat mode which does not turn a mosfet fully on.... the 555 timer must produce a pulse that is _more negative_ than the main supply battery. That means it cannot be powered off of the main battery in a simple manner. My solution is to "float" the timer's power supply. But this doesn't work for a positive going pulse from the timer... because there isn't the required _negative_ component that keeps the oscillations going. In this video I show the relationship between the amplitude and offset of the FG drive pulse, to the oscillations and the state of the mosfets. By carefully "tuning" the offset and the amplitude of the FG's output, one can get the Q2 oscillations to happen along with a partially on Q1 mosfet. Again... this reproduces another aspect of the Ainslie DATA. Unfortunately it is ignorance which has caused her to misinterpret this data and what is happening in her circuit. This video got kind of long so I didn't show what the 555 timer does. With the simple 555 circuit that I use, one cannot control the "offset" in the same way that the FG can. But I have installed the Secret of DPDT on TarBaby's clock board, so that I can go from a strict negative-going drive to a strict positive-going drive with the mere flick of a switch, live and on camera. I'll illustrate this in ...

DIY Electric Chute Rotation - Refined version 2

Here is a more permanent (but not quite) version of my DIY electric snowblower chute... 18V cordless drill provides the motor 14.4V cordless drill battery (from a seperate drill) provides the power 2-way Momentary DPDT switch (joystick) mounted to dashboard Custom fabricated battery connector for quick swapping of the battery for charging Custom fabricated drill chuck adapter that connects with existing corkscrew shaft Still needs some finishing touches like wire tuck, a proper battery container and a sturdier metal bracket for the drill (it is wobbly).
