Re: Raspberry Pi to Raspberry Pi 433MHz long distance communication

I tried using those same models in college, they only work with an unobstructed view of each other. We got maybe 50 feet of range indoors through classroom walls. I would recommend looking at the Digi XBee Pro 900HP... It's your typical XBee module except they're 900Mhz and intended for very long di...

Re: using a TI mmWave IWR1642 sensor on RPi3

That chip is very much not intended for use by amateurs, the reference manual alone is 2935 pages long. Acconeer's A1 radar chip at least has some examples written in Python for use on an RPi, but again not for amateurs.

Re: CM3 Two Camera Previews, one "hangs/freezes"

It doesn't sound like a bug but rather that you are overloading the CM3. I would also check the signal integrity coming from the cameras as you may be feeding noisy data into the CM3 and eventually crashing it.

Re: Raspberry Pi PLC/HMI?

I have several of the ComfilePi units deployed in industrial locations and have been very happy with them. They currently ship with CM3 Lite modules but I have successfully swapped in the new CM3+ Lite modules for a decent improvement in thermal performance.

Re: CM3+ Released with up to 32GB eMMC

Just want to throw it out there that I tried to boot a CM3+ Lite with a Pi-Gen image created on December 8th and it failed to boot. I re-ran Pi-Gen this evening and that new image would actually boot. The strange thing is that the custom cmdline.txt, config.txt and dt-blob.bin files I used in Pi-Gen...

Updating Pis without an internet connection

My company is deploying a new product using 3B+ Pis and I am looking for a way to updates the Pis going forward without re-imaging the SD cards every time. None of the equipment is connected to the internet so I can't use the normal update mechanisms. Is there a way to essential package up all of th...

Re: Trigger(s)/conditions for power symbol in taskbar

Just to chime in, I am having a very similar issue on Raspbian whenever I plug in a Symbol barcode reader. If you hover over the icon there's a tool tip that says the indicator is for the Pi-top laptop battery. For me this is happening with clean Raspbian installs on a CM3 and 3B+ with absolutely no...

I have experienced some thermal performance issues with the CM3 like others have reported and as a result my company is designing a custom heat sink. The more we can produce the lower the price we could...

Re: Daylight viewable 5" screen for Pi?

You may want to take a look at Comfile, they have a IP65 rated panel PC that's based on the Compute Module 3... It may be too big but it's worth considering since it has a built in real time clock and multiple USB ports for connecting to your GPS. http://comfiletech.com/new-products/cpi-a070wr-7-ind...

Re: Cryogenic Raspberry Pi & Camera CERN schematic

Two ideas for you.... Use a bore-scope so you can keep the electronics out of the cryogenic temperatures. If you can't move the camera away, you could insulate the camera and Pi so that the heat they produced is use to keep them at slightly warmer temperature. You might want to check out Cryogel-Z i...

@procount I'll give v2.5.3 shot, but did you happen to do release with that source code? The latest release I see on Github is 2.4.2f or 2.4.2g if I clone the repository.

Re: STICKY: PINN - An enhanced version of NOOBS.

@procount it looks like the issue has to do with the no_default_source option being used. A Segmentation fault is occurring just after downloading overrides.json from Github. I've attached an image of the debug log, I couldn't get it exported from the unit.
