@@theGADGETSplaylist I have no idea when my relays will arrive. I think I’m going to put some jumpers on the board to bypass the relays and continue on with the calibration and testing. Maybe tomorrow.
I'm glad your parts arrived before mine, thanks for all the tips and clarifications. Such as which way the little mcp6s21 sit, I never saw the white dots on the pcb until seeing it on a large screen :)
White dots for the AQY210 chips also Chris. What is not so plain to see is the corresponding dot on the 6S21. It's there but they could have made it more visible!
I'm finally going to have a project to use my controleo reflow oven on! I built the controleo2 years ago and got the controleo3 upgrade parts after that. I now need to implement the controleo3 updates. I just ordered the pcb's with stencils and the micros today. Now I need to order the parts.

I ran into the same problem with the short headers having round holes. Got some male matching headers on the way. Will be interesting to see the option 2 video.
I think I'll adopt it for small things like 6S21...maybe add a small amount of flux. For the resistors and capacitors, I'll go with conventional paste/component/flow. I think I'm getting the hang of having those float and surface tension themselves into position.
Since you have recommend building this, I have been looking at other DIY kits. How hard do you think it would be to add a little screen to keep this all contained as one unit? Id probably need a power source as well.

Thank you Denis for all the great content! I found your channel while searching for information on the hscope. I have absolutely zero knowledge of circuit boards and circuit board design. But after binging your channel I’ve decided I want and need to educate myself before attempting to build the HS402. It’s one thing to follow along with a step by step video, but I’d like to understand what I’m doing and why I’m doing it. Is there a chance you can present a beginners level tutorial on circuit boards, circuit board design and the acronym jargon that goes along with it? It would go a long way in helping folks like myself.
I wouldn't be the most qualified to tutor on circuit boards and their design... My advice is to start small. Maybe a through hole solder project at first. If you're comfortable with soldering, then try a SMD project. The HS101 PRO SMD is a great confidence builder. Consider joining the HScope TELEGRAM group. Lots of helpful people there including the developer himself, Martin Loren. And thanks so much for the comment, Chris!

Unfortunately no, ofeky1 I found JLCPCB the best place to send GERBER for PCB manufacture. They promote LCSC where many of the components can be purchased. The STM32F411 and the project box is best sourced at Aliexpress.

The square wave was for calibration purposes. This HS402 will capture all wave forms that any oscilloscope could. Sine, square, triangular, irregular...not matter...
Hi MacDonald:) I got the PCB from JLCPCB and the SMD components from Aliexpress there is another option...you can buy HS502 or HS512 already built and licenses included in purchase from Martin directly www.martinloren.com/shop/

@@theGADGETSplaylist I checked it today and the BOM listing only showed 3-4 items as available, although I searched them and they existed in stock. I think that the reference part number changed or something like that.

In GADGETS#86, I featured this Mustool microscope: czcams.com/video/b5T2NrFAAPI/video.html Love it! I use extensively on the channel. Chose a different approach this time...switched things up a bit Dale:)
I found most of the parts easy and cheap to buy on Aliexpress. Also JLCPCB was very cheap and produced excellent boards (how do they do it?). However, I incorrectly ordered the sop version of the MCP6S21 and found the msop version much harder to find and more expensive. Just wondered why Martin went for the msop version; there seems plenty of space on the board for the cheaper and more readily available sop version? I also encountered the same problem with the square pins and round holes! Not decided which way to go on this as the round hole solution seems less common and more expensive in terms of getting hold of parts and I have loads of square pin strips (male and female).. Still waiting on parts so not completed my HS402 yet. I decided to go for the 3d printed case; I don't have a printer and you can get a CTC A8/Prusa i3 clone kit off ebay for not much money, so decided to go that route. It will be interesting building the 3d printer and getting into 3d printing, and be useful to be able to print parts off. I know this sounds over kill but its something I always wanted to do and the current pandemic gives me lots of time to do all the things I wanted to do and never had time to do!
I too wonder why Martin chose MSOP. I had used the larger SOP on adapters for the through hole builds and were so much easier to solder and find...But, we'll forgive him:) Those round hole headers are better quality (more expensive) and required for the 20mm height of the aluminum project box I chose. Since you're going 3D, the std headers will do just fine. And speaking of 3D, good for you on getting one! I haven't "broken down"...yet... Let us know how you make out:)
I will give an update on the 3d printed case. I had no prior experience with 3d printing and there was alot to learn, so it has taken up alot of time. I was overwealmed by the choices of 3d printers available and in the end decided to go with the cheapest prusa i3 clone i could find on ebay, on the basis that i did not want to spend too much, i could replace any parts cheaply/easily and it would be a good learning experience. This worked out ok, but it would have been better to pay a bit more and go for a more reputable Chinese brand like Anet, which can be had on sites like Banggood for very reasonable prices. The Anet ET4 would be a good choice as it has all the bits included you would buy to improve a cheap Chinese clone, plus auto bed leveling. But hey life is for learning and you dont become expert in anything without making mistakes, spending time and building experience. The case prints out fine, and you can use the square cheaper pins. Hopefully someone can benefit from my hard won knowledge!
@@armunro There was a good price on AMAZON for Ender 3 PRO. They shipped the wrong printer, not the PRO version. I negotiated a rebate and got the printer for $134 CAN (which is not real money...lol) It prints well and I can always upgrade later.
