You've not told us which RPi you are using. For example, a Pi Zero consumes less power, and generates less heat than the RPi4B. That will matter quite a lot when you get to the detailed design stage; when you need to determine what your objective Junction Temperature is, and how much cooling you need to meet that objective. Are Heat Pipes a Solution? If ...

You can move heat in two ways and by using the plastic sealed box it gets very difficult to use either conduction or convection. Convection (movement of heat) will literally hit a wall of the plastic box and as you rightly surmise, the temperature will just keep increasing inside the box till the Pi gives up though heat. I would say that no box is fully ...

I finally got this working. Started from scratch with fresh install of Buster. Configured the wpa_supplicant.conf by following directions in this post - https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=274194&p=1662955#p1662955 and installed the relevant WiFi driver from here - http://downloads.fars-robotics.net/wifi-drivers/8188eu-drivers/ ...

The file has to have a few specific entries now. The minimal file contents I have found are: ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 country=GB network={ ssid="Something here" psk="passwordhere" key_mgmt=WPA-PSK } Can you edit your question and put your file here (redact the SSID and password) via a ...

You have found why you should not use /etc/rc.local anymore. It has limitations due to Compatibility with SysV. We have seen many problems here on this site using it. Following the recommendation of the developers from systemd you should avoid using it. The right way nowadays is to use a systemd unit file to start a service. With your requirement we have to ...

Question The OP already has a working python program which logs the readings of an accelerometer MPU6050 and write to a CSV file. Now he wishes to have advice and direction on how to write another python program which reads a button and starts and stops the above accelero data logging program. Answer Short Answer I read the OP's data logging program ...

You may need a few changes first. Run a groups command on the Pi and make sure your current user (most likely: pi) is a part of gpio group. If you're not, run the following: usermod -a -G gpio pi (the general syntax: usermod -a -G <group> <user>, command is *nix specific, not just Pi, read more here: https://www.raspberrypi.org/forums/viewtopic....

Eventually it worked after I reinstalled the OS changing it to the regular GUI version from the Lite one. I didn't run rpi-update again since the new firmware had been already installed. Not sure whether it's because of some issue with the Lite version either just the system needs to be reinstalled after the firmware update but anyway now vcgencmd ...

I had the same problem, looked like camera was faulty. In desperation I checked the continuity of the ribbon cable, all lines were open! Turned out to be a tiny hairline crack in cable near the termination, must have been bent too far. Cut the bad bit off with scissors, sandpapered the insulation till the metal conductors showed, glued the blue plastic back ...

I'm answering this because this was one of the first results on Google and I had the same problem. Windows has great difficulty reading a SD card after the raspberry Pi installed files on it. My SD Card had 2 partitions, the first one only being 61MB, the second one was 26GB. Next to that, there was almost 1GB unallocated. Windows can only see the first ...
