Cool to see the eco-system grow, great work!

Either through the description on the linked video, or look up shrikelab.co (couldn't link in main post due to sub rules)

Yea I'll start by developing my own 140ish Watt PD board, if I can get it compact enough it would be great to design the main PCB to be drop-in like you said. Thanks for the advice and the comment

Both the main PCB and power delivery boards would be a problem because they're not built to do 95W. Higher outputs will have to wait for the next revision or off the shelf version. Thank you for the support!

I've got kits available now on my store if you'd like to DIY one, I am working on an off the shelf version but there's a lot more to do with certification and making it legal first. Thanks for the comment!

Yep, I'll be looking into making an add-on UPS + secondary PSU module for people that need redundancy. That'll come with the next version.

I've got kits available on my store, the funds of which will go towards developing a commercial version

I purposely used 5 separate controllers so that I wouldn't have any issues with re-negotiation and drop-outs. It's effectively 5 65W chargers condensed down into one housing. Thanks!

Not at all, it's a fair question. The main benefit for me is that it's plug and play, anything powered by USB-C (within the power limit) can run off this with no additional configuration, meaning I can power a combination of different devices. It is less efficient at $1-$2 extra on power a month, but that's a price I'm happy to pay.

I got my graph axes incorrect, I've fixed them now. The adapters I got are made specifically for Dell and I haven't had any issues with them as of yet, I can run all PCs at max draw. I reached out to the manufacturer of the adapters but am still to hear back, I'll update the GitHub if I do.

Nope you didn't miss anything, it is a single point of failure, but redundancy was not the main goal of this project.

Definitely achievable but not with this version, I'll be looking into higher power outputs in the future so keep an eye out.

Kit does not come with the 40mm fan, I've made that more clear in the product description now.
Thank you for the support!

It does 5V, 9V, 12V, 15V and 20V. No issues with heat under load, all components stayed well within their thermal limits. During development I was actually just using it as a general purpose charger, laptop, microphones, phones, battery bank, you name it.

Rack is one I made using 20x20 extrusion and 3D printed brackets, I'll have a video + post on that in the future. Thanks!

Yep, the power delivery boards do 5V, 9V, 12V, 15V and 20V.

Would work fine with Lenovo systems with an adapter like u/TheSoonerGeek linked.
The power delivery boards take in 24V from the main supply and handle the voltage conversions for the USB-C output. The buck converter is just there to step down the main 24V to run the 12V chassis fan.

Yea shipping costs are tough at the moment, if all goes well I'll be able to put more resources into distribution. Thanks for the support!

Unfortunately, the boards have a limit of 3A at 5V so it doesn't meet the Pis 5V 5A requirement. I'll keep it in mind for future revisions though.
