Arduino Bottom Feed Vape Mod 2

Introduction to Arduino Bottom Feed Vape Mod The purpose of this post is to simply show you how I built my Arduino Bottom Feed Vape Mod.    If you choose to implement any of this documentation in any way, please be responsible.   There are many dangers associated with using both the Lithium Read More »

Schmitt Trigger 2

Introduction to the Schmitt Trigger Generally, We use the schmitt trigger to “clean up” a digital signal.    When digitial data is passed through a cable, you will have capacitance.   Furthermore, the longer the cable is, the more capacitance you will have.  We know that capacitance opposes a change in Read More »

MOSFET

Introduction to the MOSFET A MOSFET is a Metal Oxide Semiconductor Field Effect Transistor.   That might sound intimidating, but basically, a MOSFET is a switch.  There are two types of MOSFETS:  Enhancement mode, and depletion mode.   Unquestionably, the most common type of FET is the Enhancement mode.    We will Read More »

Transistors

Introduction to Transistors Transistors can act as a switch, or as an amplifier.    Using a transistor, we can control a large load with a small amount of current.  Micropressors, such as the Atmega328 are allowed a maximum of 40mA of current per output pin.   Loads such as a motor, Read More »

Inductance

Introduction to Inductance We provide inductance with “coils”.   You may also call them “Chokes”.    The unit of inductance is a “Henry”.  We know that capacitors oppose a change in voltage, but an inductor opposes a change in current flow.  We use inductors to filter noise in a circuit, for Read More »

Mega328 1

Introduction to the Mega328 The Mega328 is similar in a lot of ways to the MK-328 meter.  Both of these meters are very impressive in the capability.   I purchased the Mega328 from Ebay at a price of under $10!  The meter I purchased does not have a case with it, Read More »


Point Contact Diode

Introduction to the Point Contact Diode Today, I am doing an experiment that I’ve heard of called a “Point Contact Diode”.   During the World Wars, soldiers would make radios in the field.   By making a “Foxhole Radio”, they could listen to radio stations for news and entertainment.   One of the Read More »

MK-328 7

Introduction to the MK-328 Today, a new meter arrived in the mail.    This is the MK-328.    I’m very impressed with this meter for $17 on Ebay!    The meter will test many components such as diodes, LED’s, transistors, triacs, capacitors, resistors, MOSFETS, etc. At first, I was skeptical.  Read More »

Resetting Fuses (1756-OB16E)

Introduction to Resetting Fuses The 1756-OB16E module is an electronically fused output module.   For this reason, we must know the procedure for resetting fuses in the even that an overload condition takes place.    In summary, he 1756-OB16E has two electronic fuses.   The first fuse protects outputs 0 to 7.  Read More »

Restart Lockout Logic

Introduction to Restart Lockout logic Whenever we have a a large motor, a lot of current is required to start the motor.    When the motor is pulling a large amount of current, heat is building up in the wingdings of the motor.  Hence, we do not want to allow Read More »
