In this video we continue on with our schmitt trigger circuit, we always have a idle, standing voltage at the output of a schmitter circuit, thats going to be around the voltage value of the threshold design value, many times a load needs to be driven from ground reference.
So the output of...
Hi,
Here is another hobby level transistor circuit design,
I went through my course design books looking at the formulas for designing a schmitt trigger circuit, and it explained well all the design equations for the collector,emitter and base to ground resistor, for the output transistor...
Hi everyone, I've been working on a motor speed control for my mini lathe, because the board that I had in it finally blew out, after about 14 yrs. of hard use, I tried to order another one, but my minilathe, is outdated, so I can still get mechanical parts for it, but no more electronic speed...
There are many functions to be found on the Internet for software button debouncing. The logic is simple. When a button input goes high or low, wait for a brief 30ms and ensure that the button state doesn't change during that time. If it does, restart your 30ms timer and continue to check for...
NOTE:
When using the TSOP1738 IR Receiver Module in a Beam Break application it is necessary to interrupt the 38KHz signal being generated by the IR Emitter.
An example is a 'People In/Out Counter', where the beam break is used to detect a person entering or leaving a room.
If the TSOP...
These circuits are for converting a 4mA thru 20mA Loop signal to 0V thru +5V , suitable for an ADC input or a +10V
When using a LM358 OPA, the closest specified lowest swing is approx 20mV above 0V.
If a full' 0V thru +5, +10V is required use a suitable rail to rail OPA.
Take care when...
The sound active control circuit -- Using the sound to active the relay to drive the load.
Mic → Pre amp → CR Differential circuit → Schmitt circuit → Rectifier and filter → Toggle flip flop → bjt and relay
R8 -- increasing the input resistance of Q2.
C4,R6 -- Limited the frequency of sound...
It is great to see the PCBs that I produce finally show up in a project!
This is a custom NeoPixel Driver designed by Calum Knott (http://calumk.com/). Here is what Calum had to say about the PCBs:
"Robin at Mitch Electonics has been working hard on perfecting low-cost PCB's manufactured in...
