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 ...

Mae 3 Robot Project

A 7 week group project I did this quarter at UCSD. It's a simple robot powered by both high-speed and geared DC motors and operated by double pole double throw switches. The objective of the robot is to transfer rings from one end of the table to the other end.

Make: Electronics - Experiment 8

This experiment adds a 1k microF capacitor to the mix to use with our DPDT latching relay, momentary switch, and resistor. This time around the switch doesn't directly control the coil within the relay and the capacitor acts as a backup battery source for said coil.

Experiment XX: Debouncing a Switch 1 - Debouncing a SPDT Slider Switch

This video discusses what is switch bouncing and explaines how we can debounce a SPDT (single pole double throw) slide switch. It uses an SR latch to achieve debouncing and it shows how we can implement this circuit using 74LS00 NAND gates. It also examines the output of this circuit using an oscilloscope and demonstrates that the circuit is working effectively. This is part 1, in the next part I will explain how to debounce a SPST momentary push button switch using a RC circuit and a Schmitt trigger. This video is part of a module on digital electronics that is running at the School of Electronic Engineering at Dublin City University. www.eeng.dcu.ie

About Different Kinds Of Switches

This 3D tutorial covers SPST, SPDT, DPST, and DPDT switches. Shown in the video is how DPDT switches may be used as a 4-ways, DC motor reverse switch, and a power transfer. Also covered Normally Open, Normally Closed and the common terminals mean. This my first tutorial made using Blender. Audio was recorded using Audacity and the video was edited by Avidemux. All work was done in Ubuntu Linux.
