    Power Supply A Guide to 12V PSU

    The device I'm powering has its own buck-boost charger built in that accepts a wide input of voltage. Can the voltage regulator be removed from the chain? This is what I had thought, but with Batteries -> BMS -> trigger board it wouldn't power on or show signs that it is on standby power. I do...

    Power Supply A Guide to 12V PSU

    Ah, looks like you're right about that dummy trigger. So it would only work for the case where I might want to charge those batteries using the USB wall adapter. I would instead need a PD charge module, not a trigger module. The PD module you linked to is not too big and will still work for my...

    Power Supply A Guide to 12V PSU

    Wonder if you can help me with this even though it's not technically 12V but I have some trouble understanding USB-C PD for providing power to devices via USB bus. I want to use Li-Ion batteries as a portable power source, and in the past it's worked with Intel NUCs and other small computers...

    I got my USB-C PD board and trying to figure it out. It didn't come with instructions and the ones in the auction listing weren't so clear and mostly referred to a two-button board, but mine only came with one button. However I am hoping it's just that I am connecting things backwards. The...

    What did you do today?

    Replaced the nozzle and thermistor of my Ender 3 printer, and then did some PID tuning. No more thermal runway! I was able to do two prints today totaling 9 hours without a problem. Before the replacements, it used to overheat with PETG printing just under 2 hours.

    I might keep those two 8.9" Panasonic panels in mind for a future project, even though they really push the limits of "portable" and "handheld" when you add controls on the sides. The OneXplayer screen is already large for a handheld at 8.4". And the Linx vision tablet is where it gets too big...

    Here's the exact panel I bought, I went with a 7" 1200p display and it uses a 4-lane MIPI DSI controller. eDP panels are typically at least 10 inches, more for laptop than mobile use. So like you I've had trouble searching for eDP to MIPI controllers. The smaller board closer to the panel has...

    I'm still trying to figure out how to make that possible, especially for just about any HDMI compatible screen since I already ordered mine from AliExpress, and most panels there accept HDMI much more than DP. Things would be more straightforward for a DP monitor. Others on the Framework...

    If 3D printing and using standoffs I could also just adjust the base at the interior in order to get the standoffs to exactly fit. Still not exactly clear on whether I go with removable standoffs or heat-set ones. Also they could as well be screwed in on the sides with tabs holding short...

    It will be using something a lot more ambitious- a Framework mainboard which is a full laptop board with a Intel Tiger Lake processor. The board is very flat and would fit well inside the case. There have been other projects using these boards in custom cases like this one that is also small...

    While I'm still waiting on my PD trigger board, @AURMEND posted a link to GrabCAD where someone was able to hollow out shell pieces for the Steam Deck using the official CAD files. (I had once tried to do this myself but just couldn't get it right) So I got curious and took a look at those...

    Power Supply A Guide to 12V PSU

    @GuilleAcoustic that’s exactly what I’m looking for. Just a simple circuit utilizing diodes with a charge board, just wasn’t sure how you had to place the diodes. Since I’m using a 3S battery pack it could be even simpler, as I can omit the boost converter and substitute the 2S charge module for...

    Power Supply A Guide to 12V PSU

    I'm not sure yet, as I am still waiting on my USB-PD trigger board to arrive to see how that works out with the custom battery pack. Otherwise if that doesn't work as planned I can go back to using the battery connector with a stock Framework battery and plan my case design around it. With the...

    Power Supply A Guide to 12V PSU

    Oof... those USP boards are still too big, especially with the supercaps. I just need a 24W max capacity with straight 12v in and out, no conversion needed. I also have my own batter pack already, vinyl wrapped and with its own protection board. Going to see if using a double throw switch would...

    Power Supply A Guide to 12V PSU

    Anyone recommend any tiny UPS boards to use with some low-wattage power sources? Like something that would only need 12V with 2A at the most. Something like this board appears to be what I need, though even that might be a bit too big, believe it or not (it's for a very small portable computer)...
