Re: The Raspberry Pi 400 thread!

I love not having built in storage. So easy to image it to a file. Then I can really try to stuff thing up, and when it goes pear shaped, I can just flash my non-stuffed version back.

Re: The Raspberry Pi 400 thread!

Do you know anyone who is actually using a composite monitor with a Pi? *Any* Pi? Also..as above, space. (That applies to the lack of an audio output, too.) Retro gamers on CRT TV's. Which given this is like a retro computer, it would have been nice. But probably not working making the PCB bigger f...

Re: The Raspberry Pi 400 thread!

However, you can hard-power-off the Pi 400 by holding down Fn + F10 (power key) for ~10 seconds. And if you shut it down, you can press the power button to turn it back on. Can you short press for a soft shutdown? I would have liked 3.5mm audio for my speaker-less monitor and I imagine for classroo...

Powering CM4

Am I correct in that we don't need to power it with multiple voltages that come on in the right sequence? Honestly, this is awesome. Making a custom carrier board should be much easier. Especially if you are only using the lower speed stuff. Even getting a small full speed display (DPI, like in the ...

Re: 3B+ PEN & RUN Header

Brilliant. I'm thinking an ATTiny would be perfect to control this. Run it from the 5v line which will still have power, check that the TX line is high, and if it's been low for a minute or so, cut power. Push a button to disconnect from ground and let it boot up.

3B+ PEN & RUN Header

The 3B+ seems to have a change to the RUN header. RUN I assume has the same functionality, in that it's pulled high to allow the Raspberry Pi to run, and pulled low to reset. This comment on the announcement blog page seems to indicate that PEN can be used for shutdown. Will pulling it low put it in...

Re: New Raspberry Pi model 3B+ 1.4 GHz, 330Mbit Ethernet, 802.11ac, PoE

Does the new power management setup have the ability to turn off the pi? So if you Sudo shutdown it drops into super low power mode? And maybe short the reset header to turn it back on?

MOSFET & Current Limiting Resistor

Hi all, if I want to use a GPIO to drive a N-Channel MOSFET ( https://www.adafruit.com/product/355 - Can be driven from 3.3v). I am going to use it to drive a couple of 12v fans (5amp max, probably less). I plan on having 12v go in to a buck to drop it to 5v to power the Pi. Run the 12v to the +ve o...

AIY Voice HAT Hardware Reverse Engineering

I'm hoping that as a group we can reverse engineer the HAT, so we can come up with other uses for it. U1) The audio chip is an i2s DAC and Amplifier. It looks suspiciously like the Adafruit MAX98357 breakout. But there is a stereo output, which the MAS98357 doesn't have. Drivers 0-3 look like they h...

Re: On the next version of the Zero (without adding cost)

I'd love to have the header holes for the power in (so I don't bypass the fuse, etc) and for the USB. It would make stacking Mini-Hats (caps) on it a lot more useful. You could have USB hub-caps, USB wifi-caps USB sound cards. When I build a project, one of my (minor) gripes is having all the cables...

These days most designers simply use a power control IC. This is an interesting idea. Don't suppose anyone has a link to more information?

Good write up red. Are you sure they stole you idea? There kickstarter started on on the 11 Feb 2013, your write up is 21 Feb 2013.

First of all, I highly recommend that if you have a Raspberry Pi system that you want to be able to turn off, you get yourself a Pi-Supply . They are brilliant. I have one for each of my raspberry pi's. But I am a curious boy, and wondered how it works. So I've taken there open schematics, and drawn...
