yes! Anyone else would like to see? pls thumbs up

There was a couple of comments from other viewer where they didn't use a regulator and said there was built in voltage regulation. I think they said it was your voltage range they tried it and said everything worked fine! I dont have the guts to try it though!

Leaving PSU in so you can still use on AC source.

@@mikegyverComputer ah that’s awesome News! Thank you so much :)

Yes, its possible! However the Studio is 40v, so we'll need a bigger external converter. If you have one that you'd like to convert, we can work something out. Contact us via our website.

I realize this video is a year old, I don’t see that exact relay on amazon anymore. Can you tell me which one I need now?

@@ffontenot_4717 I would search up "wifi relay". there are a few brands, but the one that I usually focus on is brand that says "ewelink".

@@mikegyverComputerthank you sir!

Answering your email here so everyone can read. We did not use a buck converter. The Battery was 12v, so it was straight into the Mac. The converter you are seeing was for our input for voltage regulation.

@@mikegyverComputer Thank you mike, I just randomly checked the comment section. I was very frustrated when I didn't get any response from you.... But Thanx for Replying my query. What I understand is that you cut the first 6 lines from the power supply and separate in two sets first 3 wires positive and then 3 wires negative. then you simply connect the battery to the motherboard as negative and positive and also a separate set of cables from the battery to the input wires of the power cable .... and what I think is you used a voltage regulator to keep the input voltage as 12v for charging the battery as maybe the input voltage is higher ..... but if those wires are connected to the board directly earlier it means that it transfers 12v and stable volts. then why using a regulator if the apple is already supplying 12v through powercable, shouldn't we just connect the battery in the middle so it charges automatically in the middle and just supply the power when outer is cut? and I live in Pakistan and I can have access to the battery you have provided so what can I do and what if I can use a 5v battery because their charging circuits are easily available and to up the voltage can I use a buck converter 2596... or I just read about j5019 charging and boost module, I can connect a 3.7v lion battery and boost it to 12v and it auto cuts off power when charging is full or low Is it safe what I am trying to do and if it is safe ... then also is it safe regular use?

@@muhammadfaiqnadeem8049 1) Using regulator is for the DC input should it fluctuates 5) re: 5v. can be done, but must satisfy P=VxI. You'll need to properly size up your buck too. Good Luck!

@@muhammadfaiqnadeem8049 Please check out our engineering consultation services. Thank you.

following up on your email here. If you are still using AC input, we don't really have a solution, our goal is to use DC input and not depend on AC power for those who are off grid, or want portable power. However, we have relocated the AC adapter OUTSide of the Mac for external power. Apple over engineers their PSU, so you can potentially tap off that for your 5v power with a step down regulator.

We did install a voltage regulator, watch again.

Good point!

0.9-1amps

Nope. As long as voltage is correct hack away!

Thanks, but I think someone's done that already.

@mikegyverComputer I have seen some where they put a screen on a 3d printed mount and / or add a keyboard to the mix. I was thinking like using the pcb in an old laptop like upcycling

Unfortunately we can't see its percentage.

This should work on an "a1347", right?

Technically possible on all models, however it comes down to if there is room on the back panel to install a DC port. I don't remember which models, but some did not have a clearline to drill a hole. In that case you'd need to just come out somewhere else thats not interfering anything.

@@mikegyverComputer Might be space for a type-C port and a particularly compact regulator to bring the 20 volts down to 12.7? I don't think a typical off-the-shelf reg would be able to fit and take the amps necessary for Intel.

yes? maybe depends on how customized and small you can get the regulator to fit in

I think someone has done it already

@@mikegyverComputer do you have a link?

Yes, when power source is DC. you wont need and inverter. Power button still works.

I think you are confusing this with the Pro models. They require more power. See our other vid.

5 volt goes into protection mode

i tried

you need 4,27 -- 4,32 v

do you know why exactly? Don't arm processors usually need like 3.3V? Why does apple use this weird voltage? Reminds me of a fully charged lithium battery voltage@@peppuzzo645

Sorry, no, We only convert with user's: mikegyver.com/shop/convert-your-cable-service/

A2169 and A1842

Glad you found it useful!

Model number: A2169

yes, i'm pretty sure you can find options locally. Just be sure you regulate the voltage. Thanks!

Cool!

Not this model. It requires 12v. The newer Apple TV is less then 5v. See our other vid on that.

Thanks!
