This appears to be based on Firefox OS (aka &quot;Boot to Gecko&quot; B2G). Unfortunately, that was terminated Sept. 2016 [1]. The links to FOS on the JanOS site (such as &quot;View porting instructions&quot; on the Device List page) no longer work, though there is still a home page on Mozilla [2].<p>Edit: JanOS project looks to be zombied. The &quot;Read more on our blog&quot; link on the front page returns &quot;Server Not Found&quot;.<p>[1] <a href="https:&#x2F;&#x2F;groups.google.com&#x2F;g&#x2F;mozilla.dev.fxos&#x2F;c&#x2F;FoAwifahNPY&#x2F;m&#x2F;Lppm0VHVBAAJ" rel="nofollow">https:&#x2F;&#x2F;groups.google.com&#x2F;g&#x2F;mozilla.dev.fxos&#x2F;c&#x2F;FoAwifahNPY&#x2F;m...</a><p>[2] <a href="https:&#x2F;&#x2F;support.mozilla.org&#x2F;en-US&#x2F;products&#x2F;firefox-os" rel="nofollow">https:&#x2F;&#x2F;support.mozilla.org&#x2F;en-US&#x2F;products&#x2F;firefox-os</a>

It should be required for vendors to unlock the bootloader on hardware devices that have reached EOL. Think of how much e-waste we could reduce if we were able to repurpose hardware <i>we already own</i> instead of it just going into a landfill or worse incinerated which is often the case with e-waste shipped overseas to low income areas for disposal.

Folks who do this: how do you keep the battery from bulging and being a fire hazard after a year being constantly connected to a power outlet?<p>I wanted to do this with an older phone that just two wires going to its battery, so I thought I&#x27;d measure the voltage and then just use a step-down converter to supply that same voltage to those two pins. Unfortunately no dice, device can&#x27;t be fooled to think this is a battery and doesn&#x27;t even turn on.<p>I also tried just connecting a huge cap instead of a battery, but realized that if it runs empty the board night just assume the battery discharged too much and will refuse charging it. Also it still didn&#x27;t work when I tried.

Funny this project should turn up now. This project started with a container full of phones our company couldn&#x27;t get rid of and the question &quot;could we do something useful with them&quot;. The short version: not really. Phones consume huge amounts of energy and have tiny batteries relative to their power usage. If you want to repurpose them this isn&#x27;t the way to do it.<p>Jan, who so modestly (ahem) named this bonsai&#x27;d Firefox OS after himself, has since done a lot of interesting things with LoRa and now machine learning.

If only I can actually run full Linux on the multitude of old phones I have. Its a very affordable k8s cluster!

I always wanted to do this for a security camera it seems like all the hardware is there plus a rechargeable battery.

I really wanted to repurpose my old phone as a security camera , but android power management and lack of sensible way to automatically restart the app for an IP camera made it not very practical.<p>this could be a promising project but device support looks very lacking at this moment.<p>I also considered postmarketos but AFAIR for my particular phone it didn&#x27;t support the camera, so I stuck with rooted android with some hacks to slow&#x2F;pause battery charging (it is holding about 5min anyways)

Ok this is exactly the type of thing I was looking for. Is there work being done to open up the pool of possible hardware even further?

Suggest appending (2015) to the title unless there’s evidence this is still active?
