The efficiency of this system directly depends on the optimization of each of its components. It is important to take into account all energy costs, even those that seem insignificant. A thorough analysis will reveal potential optimization points. Only then can we make reasonable conclusions about the feasibility and predict the operating time of this beautiful device on two batteries.
using random things to hold the PCB at the right angle was so relatable for me lmao edit: btw from your github you said the case was 3D printed? Which printer did you use? it looks insanely good, no layer lines at all
This is beautiful work. Is there somewhere where I can buy the PCB's for this maybe as completed assemblies or even as a finished module? I just bought a DHO924S and this would be a great addition. Thank you for making the video. Sam W3OHM
Il suffit de rajouter encore 2 batteries supplémentaires et de revoir le design. 😉. Ca peut être top! Sinon il faut également voir avec une batterie lipo de forte capacité comme celle utilisée pour les drones. Best regards. 😉🤙
@@lorencechen I'd have thought that's at least double what the actual runtime is. This scope consumes 40W when running, so you'd need an incredibly efficient conversion to get anything like that. Have you measured it? If you have and you really do get that, then it suggests it is way more efficient than any of the battery packs out there on the market. Perhaps we could find a way of adding more cells?
The batteries are 4000mAh @ 3.7V, making each 14.8Wh. Two of those on a scope running at 38W (15V x 2.5A) = 46min. The conversion losses are about 40%, making it a pretty short time. Very nice design, but it really needs a significantly bigger battery supply. I use an INIU 40,000mAh pack with mine. It gives over two hours of running, which matches with the calculation above (5 times the capacity). That results in about 24min.
Dude, what the fuckkk is this speed!!?? Incredible!! I was going to tinker with my DHO804 when it finally arrives, but apparently, you took care of that! Are you on any other social networks? if you have twitter, id would love to follow :P
I can't open the "case" .stp file in Prusaslicer althought technically I should be able to. Error says " Object size from file DHO800_BatteryPack_CASE_V1.1_Realse.stp appears to be zero. This object has been removed from the model.". Why is so? The button .stp file I can open correctly.
It fits perfectly and looks like it's from Rigol. I would buy one if you're selling.

Whoa, that looks great. Nice job!
Frantastic design job.
Should be an official accessory...
And we already have a non-jank open source battery pack solution for the DHO800 series. That's insane (in a good way).
Amazing work! Thanks for sharing.

Salut,
Merci pour cette super idée !! Ou peut-on trouver le kit commercialisé ? Si il existe bien sûr ?
Merci
Best regards. 🤙🔧
@littlebricolo1380 no product for sale like this
@@lorencechen zut ! Many thk's ! 😢
I have the same oscillo, the 814. But your work is so funny !
Best regards 🤙

Printed by a third party, the printer should be HP MJF, Nylon, The accuracy is ±0.3mm. And the surface sandblasting.
If you ever do a run of these to sell let us know where to buy it

Not for sale,just diy
Wow. Great project.
Nice Job Bro!
Fantastic work! so beautiful. How long do those 2x 21700 cells last? about 1 hour?
About 50 minutes.

It's easier to attach a good, powerful Power Bank with a trigger.
This is just what I was looking for! is the PD input passthrough able (UPS style) or just cell charge?
Can be charged and discharged at the same time
@lorencechen Great to hear!
super!!!⚡
🎉
wow is cool
Hello, is it possible to purchase such a set from you?

So how long will it run on a charge? 1 hour? Maybe 2 hours?

@@JasonSobell Yeah.. A simple pack plugged into the USB-C is a better way to go. You can just glue on some Velcro if you wanted to mount it.
If you connect 12 volts without a type-c controller, will the dho 800 burn out?
The solution in this video is support the pd output .Do you want to connect the 12V?
@@lorencechen Yes. lead battery 7AH (gel)
Stable 12V，it’s ok

Any sources for 188数码管 led module?
Try search on aliexpress
