This was early days for HS Serie DIY oscilloscopes. Continuously evolving, I invite you to look at more recent developments before present day commitment to this build...
17:20 I almost thought you were glueing it first before testing but then you said it was time to test the unit first.
I like it even though I know that the most recent 402 one is more capable but this was the birth of that all I guess and I felt comfortable to follow all the instructions and steps you gave us.
Very happy with the outcome.
this HS101 0-20v being the birth is a very good way to put it...
was very early days in the HS Serie oscilloscopes which led to today's HS402
Nice built, very compact and clean👏!
Thanks, Martin!
This is awesome!! Thank you!
+Andres Barreiro - it is a nice scope. Glad you liked it:)
The developer has a 2CH version (HS102) coming shortly...
I was wonder with the scope software are you able to use vertical and horizontal cursor?
Diag equipment can be very expensive... To a point where I don’t get to use any until I can afford it. Now I’ll be ready when I’m done with the builds. I saw that you had many videos... you’ve got my attention 😁
@@andresbarreiro9049 - yes, HScope has measurement cursors.
If you're frugal and on a budget and yet want access to the latest diagnostic technology, you're on the right channel:)
Welcome.
Perfect.. thanks for sharing.
The HS Serie DIY oscilloscope project has progressed substantially since this first version. I invite you to look at more recent builds before choosing one.
Thanks for watching!
super Job, thanks for Präsentation
That "bad" solder may not have the flux in the core.. You might try to add a good dose of flux and try to use it again.
thanks sir great video
Hello sir, I have built it and started using it. Thanks a lot.
Just for my knowledge, is there any windows base software available for this hardware.
This HS101 was the very first circuit in the HS Serie oscilloscopes. Very early days. Good starter project and congrats on completing it!
There is no Windows support for these. The circuits and the firmware are all developed by Martin Loren and supported by his ANDROID based HScope App.
Hello, thank you for your very informative videos. I tried building one of these HS101 scopes but I cannot get HScope to recognize it. I even purchased the license for stm32Util. I get a successful message when flashing. I even removed the c10 resistor and replaced with a 2k reesistor on the bluepill since i read that it is the wrong value and might prevent some devices from recognizing it. I have tried with 2 different BluePill boards. When i connect the device to windows it makes the device connected chime but gives me a "USB device not recognized. when i Connect to my android tablet i get no reaction. Do you have any idea of what i might be doing wrong? Thanks agin
+Jose Escoto - I'm impressed and pleased that you built a HS101😉
I'm aware of the resistor issue with BluePill but it is not a factor in the HS101 project.
STM32 Utils will flash the required firmware without purchasing a full licence but I too purchased it. It is a very good app.
I will be making a video soon on BluePill, what to watch for in purchasing one, and STM32 Utils. BUT, I don't think this is your problem. Seems like you have a good BluePill board and that you were successful with the flash. You did reposition the bootloader jumper after the flash, right?
I'm thinking it's the USB cable you are using with your Android device. Is it truly OTG capable?
Keep me updated, Jose!
@@theGADGETSplaylist Thank you so much for your help. It was an issue with the OTG cable. I tried it with a different cable on a different tablet and it worked. I will be building the 5v box for a transducer next!
@@escoto88 - very handy those 5v REF Boxes...have fun!
Nice Job. You're about to cost me money AGAIN :-) LOL. Nice little project.
I think you said the box you used was aluminum? You didn't say how you insulated the processor board from the inside of the box. If the box was anodized black it may not be conductive but I wouldn't trust it. I guess a thin piece of carboard would take care of the problem. Or maybe some mylar tape?
Thanks
+Dave Sage - I was thinking "wait 'till Dave sees this" as I was sourcing the parts😋
The aluminum box has guide slots that supports the Blue Pill and keeps it from making electrical contact. But the slots are a little sloppy which is the reason I added the hot glue to make sure it didn't "jiggle" at some point in its life.
I found the solution to fitting HS101 in that small plastic box. It has a 3.5mm audio style jack. Video of that build should be released in a few days. I quite like that version.
That's flattering. Thanks
Could you also show some waveforms (other than DC). I'm interested to see how It performs on typical automotive or audio signals. Sample rate, bandwidth etc.
You mentioned the single channel scope kits that are available. I built one of those and it works fairly well for what it is. Yes, a lot of assembly but the main chip was already installed so the rest was not bad. I've done it for years so not a bad job for me anyway.
Although the first one I got had an issue with the display itself. Surprisingly I contacted the seller on Banggood and they only asked for a picture of the display in operation to show the problem (some sort of ghosting) and they sent out another one. More work but sort of fun the second time around.
Looking forward to the next installment.
Thanks
@@davesage9190 - This version of HS101 is 0v - 20v and does not measure negative values. COP probe waveforms that pull below 0v can not be read for example. No AC about a 0v line. BUT, it will read AC over DC voltages (AC coupling).
There is a +/-5v version available, circuit illustrated on the developer's site:
hscope.martinloren.com/HS101-oscilloscope.html
Another thing to note is the 10kΩ impedance of HS101 vs 1MΩ "industry standard"...so 20:1, 10:1 and our 4:1 attenuators can not be used.
It can use std BNC current clamps. It will do a fine job of all 5v REF automotive sensors, etc...
I can share these two HS101 screenshots of a 1khz square wave taken @ 100 ks/s and again @ 900 ks/s:

Good info to know. I'll check it further as time permits.
Thanks again.
@@davesage9190 - This video was already 21 minutes. It was and is my intention to cover the specs, features and limitations of HS101 in the upcoming 3.5mm jack version.
Again, thanks for watching.
hello is this working android app or apk
It uses HScope APP found on the Google Play Store. The paid version is required for HS101 to be recognized.
This guy looks like the ex CIA guy from "Enemy of the State".
+PC Planet - Gene Hackman? That's a new one:)
Been told look like Patrick Stewart. And in my younger days, John Denver...
This guy wishes you a Happy New Year!
