Oh wow,
Thanks for the heads up. I will not be attempting this circuit then. I will look for a new circuit, but I would still like to build a jammer circuit with a much smaller radius.
Do any of you have any practical experience building something like this or have any circuit schematics...
So after reading through all the comments I noticed that the antenna seems to be a Yagi Uda. Anyone familiar with these? I will read about them in the meantime.
Thanks!
Hello EEs,
I found this cool mobile jammer circuit project online https://www.electronicshub.org/mobile-jammer-circuit/, and I would like to create it for a school project. I am familiar with all the components except the antenna. I grabbed my Electromagnetics book, and it goes over different...
I finished the project, in the end I ended up using an arduino UNO over PIC. So I ask the mods to change the thread title accordingly.
Devices used: UNO, CP 2102 UART to USB
languages: Java and Processing
How it works: The arduino reads and transmits data to the PC over CP2102. A separate...
Oh, I'm not having trouble with anything. I havent started yet. I was just trying to get some best practices and see how experts on the board would approach the problem.
Hello EE friends,
I am thinking of starting a new project where I would like to use a microcontroller to communicate temperature readings from a temperature sensor that is connected to it to my pc and then have the pc store the data in a text file.
In the past I have experimented with ttl...
Thanks Klaus and Pacman.
Turns out one of my parts (IR diode) was partially damaged internally. After switching it out, I was able to pick up the input with this circuit. I replaced the RED LED with a regular .7 drop diode and added a 10k resistor as advised earlier. this was enough to toggle...
I did not change anything those are the values in getting.
Thw drops dont make sense, i think my transistor is not working properly.
9v to collector, red led with 120 ohm resistor to emitter , ground. Is my current circuit. Resistor is on led cathode so i can measure the drop after led.
I...
Okay i have used a dmm and i get .08 volts for my high and .00 for my low. How would i go about raising the voltages to detectable levels? Op Amp or comparator? Config?
I removed all delays and ran this code adapted from Okada , it works perfectly for my board. Will work on interrupt and timers now, but this is a quick fix.
while(1){
if(RB5 == 1){ //if button pressed turn on light
RA5 = 1;
}
else if(RB5 ==...
Hello EE friends,
I am working on an IR circuit using an IR photodiode and photoresistor. I want to pick up a LOGIC 1 if the phototransistor is ON and a LOGIC 0 if the phototransistor is off.
Currently I am using a LED attached between the emitter and ground to tell the state of the...
