I am running the old stretch I used before in a chroot on pi4. With schroot it even shares home directory and other configs so it is relatively painless. I currently use it to launch pyhoca-gui (remote access to x2go servers) which seems to be broken in Buster for me. So that is another solution to ...

I don't believe it's made under-cost Maybe it is not made under cost but Zero for $5 or Zero W for $9 is sold under cost. That's why shops can limit how many of them they can sell you. Some shops will sell you one piece ever and refuse second because they are simply losing money on this. Some will ...

Yes, in general, swapping to SDCard is bad, but it's better than letting the system kill processes to free RAM. This would be true if the default value was not 100MB. Without swap you get killed processes but the system works. With 100MB swap this gets filled almost instantly and you get swapping h...

Just a heads up that this DS-D6 is for $4.99 now. And with free shipping if you take more than one. Over half a year it went steadily down dollar by dollar but how much lower this could go? Now it is already lower than 10 qty unit price for nrf52832 chip at digikey

bluetooth stack that I have written mostly from scratch. I will, in the upcoming months, make the source code, as well as my mods to Circle, and a number of other interesting additions to Circle, public. In due time. Amazing, thanks, looking forward to your contributions. As for bluetooth stack - t...

And because of the way that RISC OS works, it is very unlikley that adding more HW support will make a difference in the performance, it is a very different model than Linux, BSD, Windows, etc. In RISC OS most HW support is provided by modules that only interface with those modules and programs tha...

The RPi 4B has a completely differing ports layout !! Yes, but that does not answer the question, it could still be universal enough to fit as it is not whole case. Anyway here is one for pi3 https://www.ebay.com/itm/362682376363 and indeed it looks different around hdmi ports and ethernet and also...

I have one of those "radiator protection case" heatsink fins shown on ebay, but for a 3B. ... The exact model I got was actually this one, from Amazon: https://smile.amazon.com/gp/product/B07M8SH8TM/ Does the same item works also on the pi4? There are listings for Pi4 too but are more expensive so ...

My Pi4 finally arrived yesterday and I have same/similar issue with Motorola Atrix lapdock - the only device I currently have with micro hdmi input. So far tried hdmi_force_hotplug=1 hdmi_drive=2 config_hdmi_boost=11 but still blank screen with Pi4 after boot. This same microHDMI extension cable wit...

I counted the number of SW engineers we have to support the Pi, 8 full time, 2 contractors. To do FKMS, Kernel support, Chromium optimisations, video drivers, camera and other peripheral support, Raspbian development, bug fixes and all the associated background tasks that go with all those. Now tak...

An aluminium case will be of no use unless it is thermally linked to the SOC Which is the case with 3B+ as understand it (unlike 3B) and possibly also Pi4 (sea also this and linked blogs). They explained it somewhere that the SOC is upside down in 3B+ and heat goes into board ground plane, metal co...

There is also DPI on GPIO pins so that makes it four now

On older Pis I think all three (HDMI,DSI,DPI) worked at the same time in some way.

And there are also those cheap Fresco Logic (FL2000) USB3.0 video cards (popular for SDR) that may work now with Pi4 too.

so I don't use the WiFi! Indeed. With 3B+ I use as a desktop I moved to wired ethernet too as I have it near. Also I play streamed games over Steam Link occasionally and the wireless in Pi3 has some performance issues documented here - it works fine but slows down every few (5, 10?) minutes killing...

With no case , I am not convinced the Pi4 needs any extra cooling at all (in the UK at least). Even better is to get aluminum case - it is both big heatsink and case. Especially with the 3B+ model the heat goes to the board itself so it is nicely transferred to the case (unlike with older 3B model ...

When you can have 64bit kernel with raspbian? You already missed it. https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=232684 https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=232417 https://github.com/sakaki-/raspbian-nspawn-64 It is 64bit kernel (as you wanted) and 32bit raspbian as ma...

you may try to switch to old non-MESA closed source GPU drivers via raspi-config and see if it helps?

If just looking at getting something better at the same price then the 1GB makes sense, but I would have thought an extra 1GB for $10 or an extra 3GB for $20 would lead people to choosing 4GB. Plus getting the most one can is insurance against finding one needs more in the future than initially tho...

It is not sold out, there is still 2GB version here https://thepihut.com/products/raspberry-pi-4-model-b If you want specific RAM size only then please rename topic title. BTW, 2GB was my preferrred model so yesterday I ordered that one immediatelly, looks like I am a minority, everyone wants 1 or 4...

The VC4 VPU is still there (and boots first). Bootcode.bin has moved to an on-board EEPROM so when we release Ethernet/USB mass-storage bootmodes, it'll be a bootloader upgrade and not a bootrom (new chip) upgrade. I see thanks. So I guess VPU still sets up the memory at startup then. How did you s...

Is there still VC4 style (dual core) VPU? Does the ARM boot first or still the VPU?

Anyway, what HawaiianPi said worked for me with multiple Zeros. I have same experience - with same monitor other Pi work but Zero does not show the picture unless increasing config_hdmi_boost. Also since it is miniHDMI often the additional mini to full hdmi adapter attached to same cable is enough t...

you can run 32bit raspbian with 64bit debian inside container, this is relatively painless with best of both worlds, see viewtopic.php?t=232417

I am not sure if I understood correctly what I've read previously but I think some of those libraries takeover the hci interface so the safest is to stop system bluetooth service via something like '/etc/init/d/bluetooth stop' before using it. On the other hand if your library is written on top of b...

Also, I looked it up and google says that lithium batteries cannot charge while discharging. Am I not understanding something that would allow this to happen? The idea is that to charge and also run it at the same time you need to provide more power than what your robot needs. So you don't charge a...

It wouldn't hurt to use dist-upgrade, so the documentation isn't wrong as such, but it is rare that it is needed. So you are only trying to save typing few letters (and so if 'dist-upgrade' would be renamed to 'u' you would start using it immediatelly) or do you believe the 'upgrade' is somehow saf...
