DIY gas analyzer test of combustion byproducts in engine coolant from leaking head gasket. GADGETS ARE SHARED WITH VIEWERS FOR THEIR PERSONAL NON COMMERCIAL USE
This channel is gold. I need so many of these tools and my Company won’t purchase them because I’m the only one that will use them and they are so freaking expensive. I can’t wait to make this thank you sooooo mich
thanks for the comment:) this is a very cool tool...bear in mind it is not the equivalent of a $5000 5 gas analyzer...but it will sniff out any hydrocarbons if present
You may want to consider this tool for commercial purposes. Considerable value in your invention. Many possible uses for it. Very well done and thought out.
I'm too old to seek and defend patents:) All being shared. It's the only 1 right now, but this channel is VERY global and in a few weeks there will be units 3D printed and build around the world. I get satisfaction from that...
Understood. As a holder of several patents, your analogy is on the mark. Age does make us less aggressive in pursuits. I still produce new ideas, but am too damn lazy to deal with lawyers. They cause more problems than they solve. 😁
And it's a double edged sword...we tend to only be concerned about others infringing on our patent and the cost of defending it. What if (inadvertently) we infringed. There's so much stuff out there maybe we'd get sued. And that would get expensive. I can either get buried with these ideas or share them while I'm still breathing. That's how I look at it:)
@@theGADGETSplaylist Very good perspective. Like you, i enjoy the time spent with other creative people. For what time i have left, i get great enjoyment from exchanging ideas with like minded people!
After your demo test I was hopefull the head gasket test might work, clearly it does! At work I often use the blue chemical based test for combustion products in coolant. This new gas analyzer project will defiantly get the dust off my soldering station . Thanks so much for all your work !
what do you think is the cause of CO2 detection in the known good vehicle? I’ve often wondered about this and I have used 3-4% as a low threshold for failing headgaskets. I’ve tried to find information about what other processes can cause CO2 to develop and came up empty handed other than carbon based life breathing and the burning of hydrocarbons. I don’t like testing for hydrocarbon in the cooling system because I do not know what kind of product have been used to try and stop a leak. If those products had a small amount of HC then the test is invalid. On top of that many vehicle I’ve tested with confirmed headgasket failure show CO2 in the cooling system but show no HC. The only ones I’ve been able to detect HC on were vehicles that has excessive unburnt fuel cause by a misfire. Thanks again for the great tool and test series.
It gets technical. Difficult to discuss in YT comment section. I know you're a busy guy, but I extend an invitation to look me up on the TELEGRAM HScope Group: t.me/hscope You can say hello to the gang, and we can PM about this topic. Hope to see you there Chad:) Denis
Parts are on order. Will use a M5stack that I had around waiting for an application. So there is a direct readout on the unit. Will also try to reduce the air volume involved to reduce time for measurement up and down ramps. Is there a need for the relative large volume ? like avoiding airspeed at the sensor ? Thank You very much.
there is no "air speed" at the sensor...small air pump only draws 2.8L/min ... just right, I think ... especially with the water separator modification (pictures in download folder) by all means, take the basic concept of HS101 BLT GAS and run with it, improve on it...all good with me:)
we have to take the % numbers with a grain of salt ... I did my best to calibrate to 15% @ tailpipe (if MQ-2 had 7 minutes warm up time)...more warm up and less warm up can change this...point is it detects and we can get a feel for strong or weak presence...
Great built Denis💪, thank you so much for sharing your results and help All of us to make our work easy and with in the budget, Can we use HS402 for this purpose ?
we'd need separate power to the MQ-2 module...too demanding to be powered through phone USB...and that's where my concern would be, not sure about MQ-2 sharing ground with lithium pack AND with LOTO/phone USB... maybe OK...but that would be my concern, Grunter... It was our talk about head gasket testing a few months ago that got this project from the back of my mind (where it was for 2 yrs) to fruition:)
@@Grunter123 MQ-2 seems to do as good a job as MQ-7 with carbon monoxide while also excelling at detecting hydrocarbons which the MQ-7 isn't much good at MQ-9 is a whole different animal, cycling from 1.5v and 5v ... not friendly to the HS402/HScope method

I hear the excitement in your voice during testing. Well done. I like the gadget. That's the way to go, diy homemade functional tools. YES.
a lot of work went into designing/building/testing/filming this, so yeah! , it's nice when things finally pan out:)
Expanding the product! Always great work Denis!
great tool!
Great video, on the first part remind me Emmett "Doc" Brown of the movie Back to the Future. Cool!
all I need is the DeLorean:)

THIS IS VERY INTERESTING, I HOPE TO SEE MORE ON THIS PRODUCT THANK YOU !!!!!
It's reached the goals I had set for it. Anything more from here would be BONUS:)
3D printing has taken your gadgets to another level!
it does open new doors, all part of the fun...
That is one handy device!! Thank u
I love it Bill. Great addition to the channel!

Wow, that's great Denis!
yeah, it's doing what I had hoped Dave...am pleased:)

merci beaucoup tres interressant pour du diag

Very impressive indeed Denis. Think you will be finding applications for your rig for sometime to come. Bonne Annees 👍
Thanks Ian...and you've got my attention on those fuse color schemes:)
Very impressive, I didn't expect it to pick up that much co2 in your demo bottle of antifreeze.

Hi dear
Think you for your amazing work
Can you make or add Bluetooth to hantek 1008C please reply I’m looking forward for it god bless you
this is not possible...bluetooth is ONLY for HS101 oscilloscopes we build ourselves...
Great built Denis💪, thank you so much for sharing your results and help All of us to make our work easy and with in the budget,
Can we use HS402 for this purpose ?
Thanks Ramon and NO, I wouldn't recommend HS402 for this...
Wow, that is brilliant Denis. Confirm you could still make this build & link by BNC to Loto instead of 101 & Bluetooth?
we'd need separate power to the MQ-2 module...too demanding to be powered through phone USB...and that's where my concern would be, not sure about MQ-2 sharing ground with lithium pack AND with LOTO/phone USB...
maybe OK...but that would be my concern, Grunter...
It was our talk about head gasket testing a few months ago that got this project from the back of my mind (where it was for 2 yrs) to fruition:)
Denis have you still got the MQ-2 sensor in this demonstration here measuring the Carbon Monoxide?
yes...MQ-2 proved to be best all 'round sensor
@@theGADGETSplaylist So did you not have any luck with MQ-7 & 9?

@@theGADGETSplaylist Thankyou Denis, I am going to attempt making one.
