Great project. For most people when they are talking about mechanics they think the mechanic should always wear dirty coveralls steel toes safety glasses and their hands are always greasy and they can not do nothing other than turning wrenches. Your talent sets a perfect example for what a real mechanic looks like today. Not only can they turn the wrenches or how many snapon tools they have but also they are able to manage to perform tasks across their field from mechanical to electrical/electronics to IT whenever needed.
Unfortunately the pay in shops hasn't caught up with the skills that are required to do this job. So most shops can't hire someone like me, because I am already making good money doing IT for a living. Most shops are still just hanging on by a thread doing brake jobs and suspension work and occasionally winging a few parts at something and getting lucky.
This is good for all sorts of pressures not just compression check fuel, coolant, exhaust back pressure oil pressure any pressures les than 300. Tom you are a very knowledgeable and resourceful guy I have no doubt you will learn diagnosis with a scope and become good at it. You definitely understand technology which is a huge advantage as most mechanics have a difficulty grasping things like this. Thanks for sharing the info on pressure transducer. I have seen the pics scopes under 300 dollars so they are attainable as well.
My understanding is that the smaller Pico wont' run the automotive software, but another viewer was telling me that you can run the auto software in demo mode, setup the test you want then save all the settings to a file and open that settings file in the normal Pico software. While not ideal, it would still be way better than the Hantek.
Dang Tom, your pretty smart. That's fantastic and I can see the comments coming in to buy a few. I gave up on my Hantek. I can get some basic information but I get so aggravated with it I find myself not enjoying the work. Since my work is a hobby, if I'm not having fun I move on. Great effort on your part Tom.
I have ordered some stuff to build some. I am going to put the circuit on a real etched board, put them in a nice case. I also found a nice transducer that comes with a 3 meter oil resistant heavy duty pigtail. I am going to put them up for sale and put the money into the scope/scantool fund.
Nice work. Osc482 is a nice cheap scope with low noise. You can the use that with Hscope on an Android phone. Hscope has an automotive module. Also the Osc482 free pc sostware is quite nice with good/long recording. Think there is a free andriod app for the osc series. Osc482 made by Loto Instruments.
Hi, when reviewing the waveform you can still change the timebase and voltage to check out the waveform detail, but not quite like the pico. I still think you must master the Hantek first. I'll use the Hantek 6022be all the time and that only records 5 volts without changing x10 switch. Very good project.
good thing when build your own tools is you really know how it working . good job . Hantek gets you started but soon be time up the game . Once you start doing like 20 cars a week better equipment and better technique makes better results in shorter time . Keep having fun ...
Not there yet, but I've done 12 in a week. That's just evenings and weekends. Definitely need a better scope, I think I want a better scope more than a bi-directional scan tool and a JBOX. All are on the list.
12 still a lot as a side line and making it faster diagnose the common issues and enioy equipment you using is key . I can do over 3/4 of my scope work via 2206 without needing go to 4 channel autoscope . Have a look at vids on the 2000 series in auto testing and see if do you as an acceptable improvement . would be worth looking at a autel or launch for lower cost first bidirectional santool perhaps, pending on how covers most of what you work on . Keep chipping away at the junk and re-invest as can, quicker you own it quicker it paying you back . Other thing consider is your charging, maybe little little more can be charged making diag tool funding quicker turn around . You got enjoy doing it so sensible decent diag tools a must to enjoy the process and grow knowledge, confidence as well as business . Have fun ...
Very detailed, thank you. I bought stuff to build one at the beginning of the year and still haven't built it yet. LOL I'll be using a new ac pressure sensor for a mid 90's gm as my sensor. Looked let you had a nice capture for what little money spent. 👍👍👍
The linear regulator will run very hot, around 212 deg. It’ll shut down when reaching 140deg, then turn back on when cooled down. Try a step down convertor? Possibly shielded to prevent RF interference.
I did a similar thing using the same traducers only I used a 12 v to 5 v converter for only a couple off £'s , get some lower value traducers and you can use them to see turbo boost etc just need to use different connectors to break into what you want to use them for, I have a 4 channel Hantek and I have a couple off 2 channel Pico 2205 scopes and they work a charm just need to set them up right
It's not going to get damaged. There is no spark in the cylinder your are testing so that cylinder isn't super hot. You engine typically stays around 200F
Hey I have couple of questions for you. I have two 100uf 50v can I use both of them? 2nd question I have is regarding LM7805 I am getting 9v on the output side of it and 5v in the middle pin. I am not sure are those supposed be correct voltages? Please let me know thanks!
Yes you can use them in Parallel across the circuit which will give you 200uf, and it will work fine. The capacitors just work as a buffer here to provide quick current, so more uf is better. On the 7805 the pin 1 should be the first pin on the left as you lay it down with the lettering facing towards you. Pin 2 is the middle pin and it should be ground (negative side of the battery) and pin 3 should give you the 5 volts. If that is not the case then you may have a bad 7805.
Hey, just wanted to update you, first LM chip was fine I just had the chip the other way around. I followed your direction and sure enough I got the correct voltages. 2nd I got a 500psi transducer, I could've swore I ordered a 300psi one. Oh well I will order a 300psi one soon. But the end result was good though. I do get a clean waveform, I tried it in maxiscope and a snap on vD10 scope. Once again thanks so much for all your help and that video you posted, saved me couple hundred dollars. Now have to get a project box to box this thing in maybe get a toggle switch.
MY NAME IS MARCOS AM AM DO BRASIL, I WANT TO MAKE A TRANSDUCER LIKE YOURS, BUT I TRYED SOME HERE AND THEY DELAYED. YOU KNOW HOW TO TELL ME IF YOUR HAS DELAYED. HERE IN MY COUNTRY WE USE MPX, BUT THEY SUPPORT 7 BAR. THANKS
@@frugalprepper here in my country we use the compression transducer vs rotation sensor and the compression transducer vs vacuum transducer a lot. so it slows by an average of 12 degrees in relation to the rotation sensor.
@@frugalprepper I see some sensors; at least the one I bought has a tolerance of 4.9v to 5.1v. So I guess I'll build my own. I went with SSI 500PSI. It's said to be as fast as a Fluke pv350. I wanted the 300 but it's on back order. I found some step down units prefabricated and project boxes on Amazon. Thanks for the upload!
This guy came up with the instruction/specification manual before building his pressure transducer. SUPER smart!!
Great project.

Loved this video... Reminds me of my old projects... And I love when people make own tools.
Thanks. I am having a lot of fun and trying to learn to get my diagnostic process to a new level.

I'll use the Hantek 6022be all the time and that only records 5 volts without changing x10 switch. Very good project.
Can you hook up your hantek to a PC to use their scope software? I've had the worst time trying to download the software.

Not in this application where it is providing so little current.

thank you for the video which I used to make the same tools

Yeah I've seen those on e-bay, and that would be the way to go, but I was using what I had in my leftovers from other projects.
two thumbs up!
Thanks!
Awesome video!!!
Thanks!!
What was the total cost of the project? Looks good.
I don't know. Some of the stuff I already had.
Good Project!
Thanks!
Hello !
Very interesting solution. With a hot engine running, how quickly will the sensor get damaged?
It's not going to get damaged. There is no spark in the cylinder your are testing so that cylinder isn't super hot. You engine typically stays around 200F

Why can’t you use a 4.8 v battery pack?
You probably could

A set of what?
No such thing as 0 psi on earth. Atmospheric is 14.696 psi
Great!
you can solder better than that. Our NHRC boards looked better.
Well its a prototype Matt. I've got my gerber files done to have a real boards etched up.
