Re: Help: Raspberry change the polarity

Another possibility is you have plugged the meter leads in the wrong way round on the meter. As you pi would not work if you had 5V on a ground pin and ground on the 5V pin. That's what I meant pcmanbob, if the OP connects the VM correctly (both polarity and Pins) then what he describes is impossib...

Re: Help: Raspberry change the polarity

Are you sure you're connecting your voltmeter correctly?

If you are your post makes absolutely no sense.

Re: Are 52° celsius safe for RB3 too keep it work forever?

Best passive cooling system is the very pretty FLIRC case. https://flirc.tv/more/raspberry-pi-case I prefer the Argon One Raspberry Pi Case . Although it has a fan this can be turned off via a configuration script. Easy access to GPIO's via a removable cover, ON/Off/Reset switch, all ports redirect...

Re: Help Wanted Mates

Regarding lightning bolt, it's not always a power supply issue. You say you have a Pi 3 but you don't specify which model. Excluding the compute modules there are currently 3 (B, B+ A+) older kernels (of which yours appear to be) may show the low voltage icon when not necessary. Start with Rasbian (...

Re: Do-able with Raspberry?

Your query is a little ambiguous (eg define system on/off) but yes it is possible to do with a Pi. I'd start by reading Build a digital Raspberry Pi scale . For crying out loud, you've gave me another idea for Pi's. I'm a dog lover but occasionally I'm not around to feed/water him now I'm going to h...

Make/Model of your LCD?
Make/Model of your powerboost?

What else will be connected to your Zero?

Re: Cluster Pi via gpio pins

Damn you mahjongg ;)

I was only planning to create a ZX Spectrum based on an article in HackSpace June 2018 #07.

Now I've got to buy a few Pi's to emulate Agnus, Paula & Denise.

See these PI's, they're not like marmite. You don't love them or hate them, You love them and hate them.

Another point to note, never ever connect anything to the GPIO's when the Pi is connected to a power supply.

Re: Keyboard

I can confirm it works with Rasbian stretch and Pi 3B+, at least alpha numeric, you may need to do some key remapping for punctuation, special function keys etc(US layout not UK) but touch pad and A-Z 0-9 work fine.

You can't. The SOC on the Pi is limited to 1Gb.
using BSD 128Gb SD?
You could use swap space but that would be a question for the various BSD forums.
