I have an obsession with making things that don't really need to be made... (Battery powered desktop)

[JankyadventureswithJackson]

Hi guys, first time posting here, long time watcher of LTT. Watching the videos has always inspired me to make some interesting projects over the years.

 

Here are my latest two projects

 

1. Battery powered desktop PC with an I5 12400, and a 3050. It uses a pico PSU and 30AH of batteries, playing games at about 130W total power draw it lasts about 6 hours on a charge. I have had this for about 2 years now and been through about three revisions and am about to make a fourth.

 

2. I've also been working on a slimmed up egpu eclosure for my framework 16 so that I could reuse my gpu from my desktop. The last pieces are on my printer now. It uses a slim dell 300 watt power brick I got for free with a pico psu and a voltage converter as well similar to my battery powered desktop. (Crappy PSU for scale)

 

I'll be making a video about all this soon! Thanks and enjoy!

Soo a PC that is powered by a UPS, basically.

Really cool! I do wish I could create some of those wild things LTT does too.

Yes but much smaller and better runtime.

Don't forget the slick looks

I mean admittedly it does look a lot more refined than just that.  Also missed the joke of it being a laptop.

Yea, seems cool.  I mean as well, I'd imagine (I could be wrong), but since you already have a DC battery bank essentially if you could almost skip the inverter to 120V AC and just create your own power supply unit.  I'd imagine your DC to AC converter already has a 95% efficiency mixed with another power supply converting to AC to DC and you start sitting at 95%...which would put efficiency ~90%.   I mean sure, creating your own likely won't get have the best efficiency but I wouldn't be surprised if you could get better efficiencies than DC to AC to DC of the current setup.

It uses a DC power supply so no conversion other than the charger.

UPS systems are pretty crappy really.  Power stations are WAY better.  I have devices in the house that can run for days!

If i need a battery that can make my pc run for days, I'd be angry / worry at my country / house electricity. Really.

I started adding them right after the Hurricane last year a lot of the city was without electricity for multiple days, a week in some places.  I have 14kw in the garage on a 3kw inverter (with 20a line to the office) plus a bunch of tiny power stations all over the place.

 

They were working on the transformer for a few hours last week we watched the normal show off the server/nas/plex and played on the computer a little.  Plus, I was mobile it used to be I couldn't open the garage door without power (from outside the house)!

I doubt that's something that most people can afford tbh.

 

But then again, electronics prices in USA/1st world country does seem way lower than in my country

[Doobeedoo]

This reminded me of near day outage in entire country region we had last summer due to so many tourists and AC usage and whatever else. Grid collapsed even parts of neighboeing countries in Europe heh. Funny they evwn mentioned it may happen again. I really should get good UPS heh.

 

Now make 100Wh multi cell phone battery that can charge at 1KW in 10min and not hurt me :D.

The big system was something like $2k but probably only because I built it myself.
