This is the first part of the process I go through in designing a new circuit, since I am not a professional in this field, I cannot make the claim that this is the way to design circuits, so I can only share my methodology of designing circuits at a hobby level.
The method I came up with is in...
This is part 1 of the design process I use, to design new circuits from scratch, I show the conceptual details of the circuit in its simplistic block diag. form, then I show later how, the original design needs to be reworked with added circuitry to make it work properly.
Part 2 coming up...
This is a robotics project I designed and built about 20-30 years ago, it is based on the old radio shack robotics gripper robot, I didn't want to spend money on buying one.
So because I enjoy engineering things,
I decided to take up the challenge to design and build my own version, using all...
Hi,
This is the design and build of the binary to decimal decoder, it is fully functional, and this video demonstrates the working of it,
showing the workings from the toggle registers, through the binary outputs, and finally into the decoded outputs, showing the digital outputs from 8...
I cant believe its been 5 years with MitchElectronics... All started because I made simple PCBs. Well, I have come along way now and have just achieved through hole plating! Thats right! And at the same time soldermasks!
Its easy to plate or apply a mask but what is hard is consistantly doing...
OK in this video, a lot of progress is being made, I just learned about synchroneous counters, reading through my books and doing research on binary up/down counters, and in this video I share what I learned and how to implement steering circuitry (logic gating) to acquire the abiity to count in...
Quick video explaining how and why I upgraded my design of a data flip flop forming a ripple counter, to a set of JK flip flops forming a synchroneous binary counter.
This design uses one less transistor, bringing the total count per register down to 9 transistors now.
And it works reliably.
One of the necessities of posting a question often requires that you provide a schematic or pictures of your project. You can draw a schematic, upload a picture or get a screenshot. But how do you get it into your post?
(Note: If your having trouble getting a schematic drawn, try the Windows...
this video is a continuation of the master slave flip flop series, this is demonstrating how to take the basic circuits, already built, and how to configure them by manually placing jumper wires at certain locations in the circuitry, to perform the toggle functions.
Then I go on to show how...
This is an upgraded version of the "AND" gate configuration, that goes into these m-s flip flops, the old version used two transistors, this new design uses only one transistor, its bias is different as well, originally the old flip flops contained fourteen transistors, with this new upgrade...
From time to time there will be a thread on the construction of a root locus. These were methods used long before computers achieved wide availability. They are especially useful for transfer functions of third and higher orders.
For a system with a loop transfer function G(s)H(s), the first...
This is the conclusion of the Master slave flip flop build project, using all discreet components, this video demonstrates the ability for these type of registers to be couple together in such a way that makes them into a binary counter.
From here the next project may be to design and build a...
Hello,
Here is a sneak preview, of the set up of four master slave data registers, for this series of videos I'm doing demonstrating the design and build of these kind of circuits.
In this video the LED's outputs are scattered over the breadboard as they are connected close to there mating...
Hi everyone, as you know I like to share this transistor circuit design stuff with people who are interested in this at a basic level. As I am not a professional in this by only a hobbyist, however I like to share what I learn from my design builds.
As a hobbyist only, my designs are only at...
In this blog entry we'll be looking at consensus terms in Boolean logic. What they are, what they tell us, why they are useful, and how to work with them. Although some of these concepts lend themselves very nicely to dipictions using Karnaugh Maps, we will work in strictly algebraic terms, if...
This is a tutorial to build a transistorized light detector, it is assumed that a person choosing to build this circuit, has a basic understanding of electronics fundamentals, and are familiar with the basic theorems such as (ohms law, kirchoffs voltage and current laws, ect..) that way the...
1. Using a simple RC filter as resistor and capacitor for 5V and GND of uC surges and interference problems, processing the reference method, the R-value is according to the total current consumption of uC, when modifying the R-value still unable to achieve the desired effect, and then change...
I did this some time in the 1980's. Originally intended as a flashing light controller for advertising, and run on batteries charged from a solar cell. It is supposed to be a night detector that is fairly immune to the headlights of passing cars. The batteries charge in the day time and it...
hi every one,
i want to make the simple circuit for automatic floor announcement in elevator project
complete description is given below
the lift is of 9 floors,when 1st floor comes,the announcement should be like "floor number one" by means of speaker,in my elevator project floor detection is...
A recent comment prompts me to list the basic fan laws here.
For a given change in RPM,
CFM2/CFM1 = RPM2/RPM1
Static pressure 2/ Static Pressure 1 = (Rpm2/ RPM1)^2
Horsepower 2/ Horsepower 1 = (RPM2/RPM1)^3
