In this video, I present the enclosure and PCB-based front and rear panels for my RP2040-ADS1256 DAQ board. With this little addition, my product is almost done and ready to be sold.

Thank you for showcasing your excellent work! I'd been hoping to find something like this when I started a long term hobby project of refurbishing an HPLC system. Playing around with a variety of different detectors now. I'd been looking at ways to circumvent the need for expensive proprietary peripherals and software and this is fantasic. Perfect for "DIY Lab [with] hanging wires"... exactly!
Thanks! Actually, my very first encounter with this ADC was when I had to revive a super old lab equipment. It had some super old logger with a DOS computer. I still have the original prototype tucked away to remember where instarted. Since then, I learned to code a bit better and to design PCBs...etc., so I ended up writing my library and designing my own board for this ADC. Since I know what kind of things one wants to measure in a physics lab, I tried to follow those ideas when coming up with the product. I will soon follow up on the project with the accompanying software and some use cases. Stay tuned!
Amazing work! Also crazy how fast PCBs arrive these days, we are living in an amazing time.
Thank you! Yes, both the manufacturing and the transportation are insanely fast! Super convenient.
Wow! This looks professional!
Thanks! That's the goal to provide a professional product! The accompanying software will also be good, I hope. I will show it soon in a video.
👍👍👍👍👍
😎👍
I have tried to follow this but it is way, way over my head. I even read the blog post but I still have no idea what this thing can do or how it might be used. You say data acquisition but for what?
You can measure any voltage source in the +/- 5 V range. Load cells, Wheatstone bridges, thermocouples, any sensors that respond with a voltage proportional to the measured signal...etc. You can decide what data you want to acquire with the device.
nagyon király és nagyon profi.
Köszönöm. Lesz még egy verzió 1-2 héten belül, az egy fokkal jobb lesz.
Been learning bits & pieces of PCB layout - smart about the blank PCBs as caps. What plugin did you use for the curves? That's one pretty board you designed - kind of a shame to hide it lol
Thanks! The plugin is "kicad-round-tracks" from an author called mitxela. It is available on his GitHub. I am also a bit sad about hiding the PCB, but I am hoping for some benefits from its shielding effect. Will see, I will try to do some measurements later on.
24 bit ADC 😮! are you planning to use this for EEG?
Or load cells, or strain gauges, or thermocouples, or RTD sensors, or similar stuff. 😎 I will publish a whole bunch of application videos.
Didn't say or warn what the maximum input voltage is.
Hi! It is written in my library's documentation and in the ADS1256 chip's documentation as well. If the buffer is disabled, it is +/-5 V. If it is enabled, then roughly +/- 3 V.
And the gloves are for?
So you can ask this question. 👽
Some of us have eczema, bitten fingernails, scarring etc. I don't like my hands being videos or photographed either. If I have to, I wear surgical gloves or jeweller's gloves.
@@yrath5034 It is not the above issues, but my skin is rather sensitive. And since I use IPA to clean stuff, I would rather use gloves so it does not mess up my skin. Flux, solder paste, thermal paste and glue are also the reasons.
