- Picture of Power Logic Probe
Having a logic probe on your toolbox it's a very useful tool to analyze and troubleshoot the logic state of a electronic circuit.
You can easily find out the High state or Logic 1 , "Positive", and Low state or Logic 0, "Negative".
But it's possible to improve the potencial of this tool, it would be nice having light on this probe to illuminate the area of work that we are probing.
When troubleshooting we can make mistakes so it's nice to have a probe that is protect against short circuit.
And also having the opportunity to give positive and negative to the circuit at will to power devices.
To power the probe connect the leads to 12v power supply and push the power and reset button to turn on the probe.
Now you can probe the wires to check the polarity, the red led will be positive or logic 1 and the green led will be negative or logic 0.
Thanks to the white leds you will always have a light work illuminating the wires under test.
Besides probing you can also power devices for exemple in a car, lights, horn, radiator fan, relays, etc , with the power button position 1 will give 12v positive on the probe tip and position 2 will gibe 12v negative to the probe tip.
The probe have also a circuit breaker to protect the probe and electronic circuit under test, to power back on just push the ower reset button.
This is a nice and easy project to make and a very good tool to have for diagnostic the car wiring or a electronic circuit.
Excelente aporte... saludos desde Chile 🇨🇱
Pudiste fabricarlo?
@@davidenriquesalassanhueza6135 ves a esta pagina se ve bien www.instructables.com/id/Power-Logic-Probe/
Anthony Ortega are you the owner of the video?
Muchas gracias por tu aporte.... un abrazo desde Chile !!
Gracias
Viva el Chile!
Pudiste fabricarlo?
@@davidenriquesalassanhueza6135 hola pudiste fabricarlo todavia no entido como funciona el relay
Hi Id like to build the power probe, can you provide a material list and a more clear schematic, its not very specific, regads from México!!
Your wiring diagram is not right, there is a mistake on the second transisitor (BC557), because the configuration is bad, led and ressitance must be connected on the emissor. Mr Pozo found the error, he is an electronic enginner and he simulated it on proteus program. The schematic diagram was sucesfully tested.
a 12volt relay, 5volt zener diode two 1n4002 diodes , bc47,bc557, 22ohm 68ohm two 20k, 1k 2k resistors green led , red led two white led's , small pb reset switch spdt switch , wire 12 volt power source and some sort of probe tip device , could use finishing nail in a plastic
what sort of relay though?
@@adrianovergara1784 looking at the relay in the schematic at 2:21 , it is a single pole, normally open. Reading schematics will tell you lots of things that aren't written in words. This is one of those cases that just looking at the schematic will tell you what you need. Many relays include the switch contacts for both normally open and normally closed. So, basically just about any relay.
I do think that is a 1n4001 diode. His 1s look like 2s. A 1n4001 should work for this circuit. Also, where he said 20k and 2k resistors above should be 10k and 1k respectively.
Привет. Из чего сделан корпус?
Hi sir let me ask a question, is it possible to add up a digital volt meter to this circuit to show voltage and also would it be possible to detect both positive and negative as well as oscillating pulse like for automotive? Plus add up buzzer to make a low sound for negative and then high sound for positive and oscillating sound as well? Thanks
Quien tiene el plano mas claro y el circuito electrico saludos desde colombia muy bueno el circuito
Hello can you please give a better schematic please man
Anyone have an idea what kind of enclosure that is?
please update with better schematic
Qeway dónde se puede comprar
still waiting....
Also wish there was an beter schematic :'(
Very good video. What's the music ?
Thanks it´s my own music
hello can i have the bill of materials and schematics please?
Amigo me podría compartir el diagrama
If you only show how you build and put where to get the components I believe this video will have more views.
hello can you send me the bill of materials used in this project? oh and a clearer schematics please I am just a newbee on electronics.
Thanks
It's all common electronic parts so not too much expensive
Engineer of None hi I wonder if you could give me the list of materials I am sorry because the schematic on this video is unclear specially for the transistors is Jc337 is this PNP and Jc537 NPN? It is not clear on the video. I appreciate it if you could send it to me, I really want this project. Thank you very much!
Engineer of None Can you build me one ?
@@eugenelim7016 they are BC547 and BC557 transitors , all parts are easy to get at MOUSER.com
@@roberttrompeter8775 do you know what type of relay did he used?
