Raspberry Pi Palm-Sized Computer (this process will work with all varieties) This process can also be done headless meaning you wouldn't need to use peripheries, check this guide on how.

Crontab (a method of getting the software to run on boot) and time synchronisation (pulling the time information from the internet) will also work perfectly fine with a Read-Only Raspberry Pi.Īs always if you have any questions, queries, or things to add please let us know your thoughts!īelow is everything you need to set up your Raspberry Pi to be Write-Only. No soldering or extra hardware to make a safe power cycling Raspberry Pi.

This means if you create or try to download files larger than the RAM available the system OS won't allow it (or be able to do it).ĭata can be pulled from a Read-Only Raspberry Pi via USB Drive or in any other normal manner. All these created files on a Read-Only Raspberry Pi are going to be temporarily stored in the RAM. This is because we have completely disabled the write function of the Raspberry Pi. Once you have turned your Raspberry Pi into Read-Only no changes (be it creating new code, changing files, deleting directories) will be remembered next time you turn on the Raspberry Pi). For instance, if you create a directory on the desktop of a Read-Only Raspberry Pi when it restarts that folder will have disappeared. With no concern of corruption, your Micro-SD card will be able to run its natural life, which should be 10+ years. This set-up is perfect for kiosks, multi-use work terminals, educators managing a classroom worth of Raspberry Pi boards, and completely finished projects that you want the ease of power cycling. Note that this is also a reversible process. In this guide, we are making our Raspberry Pi Palm-Sized Computer Read-Only.

Then corruption will never occur and you can be free to power cycle it whenever you desire! So, knowing that Micro-SD card corruption only occur when you turn off the Raspberry Pi in the instant that it is writing new information to the Micro-SD card, lets completely stop the ability for the Raspberry Pi to write new files to the Micro-SD card. There are situations however where it is inconvenient to turn the device off safely every time (be it due to location or time constraints). Lets be clear, when you Safely Shut down the Raspberry Pi it will first check that it has completely stopped writing new information to the Micro-SD card, and once the Pi is sure, it will then stop supplying power to it’s circuit board. Thus, Safely Shutting via the operating system or a safe shutdown button is crucial. With a normally set-up Raspberry Pi, power cycling can cause your Micro-SD card to become corrupted. Here is a solution so you can turn your Raspberry Pi handheld computer on and off from the power plug (power cycle it) just like any other appliance in your home! And it can all be done through only one setting. Raspberry Pi Pico W with Soldered Male Headers Price: $15.20
