Which 16 channel logic analyzer would be a better choice?
Kingst LA1010 USB Logic Analyzer 100M max sample rate16 Channels10B samples MCU ARM FPGA debug tool Oscilloscopes
Or better to pay a little bit more and get 2 in 1 (oscilloscope and logic analyzer)? but its 10Mhz on 16channels.
Hantek...
Some people suggested to get 16channel logic analyzer. I am considering buying it. What do you think?
I think it should be easy to understand how display works, or it still wont be that easy?
The reason I want to hack this specific display and not to buy any other from ebay is that I would keep...
Not sure how long my perseverance will last, but I hope that someone, if not me, would hack it. I would love to see that you could take any display from any product and reuse it in your project.
Display has "Chip-On-Glass (COG)" (those black spots at the bottom), so it has controller built in...
More investigations:
I am able to change contrast from original device, but I don't observe any voltage drop in any of the power or other pins. Does this mean that contrast could be sent as a command not as a separate pin input?
As I don't have oscilloscope (I am considering to get it if it...
Well I don't mind burning the screen if that is your worry. I have few of them. Still I would prefer not a brute force approach, but better to burn screens while trying than just to move on to other project. But I don't know from where to start guessing?
Well I am not very experienced, I don't...
So I did further investigations. This display contains of 2 256x13 pixel displays.
Display pins -> Meaning (where goes on original board)
2 -> GND
3 -> GND/Power (one display goes to GND another to Power on this pin)
16 -> GND
17 -> Power
18 -> D0? (on original board goes to MC74VHC541 Bus...
Hi, I would like to try to play with Optrex 323 1867 (rebranded as KYDE 3232351) monochrome display (256x26 pixels).
I did not find any documentation about it. The only thing I found is Optrex 323 display:

As I understand it contains of 2...
But this will consume power on idle correct? Will my circuit with 2 realay work and wont consume power on idle?
Circuit should not consume power on idle, and once turned ON it will do power LED and play sound with "Mono MP3 decoder module".
Original schematic is here...
Circuit should do the same as original circuit in first post, except that it should have push button connected to ground instead of +12V.
Nice idea!
This is my new circuit, is it correct?
And how could I edit shema that the button would be connected to ground?
Can pin 3 give negative ground instead of power? Or its not possible to modify shematicsthey way I want and that it wont consume power on idle?
Hi, I would like to modifie this "555 Low power Consumption Timer Circuit":
The problem is that I have push button already installed in a car and one side of it is connected to the ground.
Is it possible to adjust schematics to that button?
would this work and consume 0 power when off? Also...
Electrolytic capacitor seems to be fine visually and also when measuring resistance it does have resistance and it seems its rising (I guess capacitor is charging while I measure?).
So next guess would be relay? It has 10pins so it wont be easy to remove it from the boars...
Hi, this module of the car has failed and does not activate electric motor although it responds to master computer of the car.
So I wonder which component could have failed in it?
Which components are most oftern known to fail in circuits? Is it relay which failed? Could I test components...
