How can you leave that 'in a McDonalds for days'? I bet it would be nicked within the hour (by someone thinking it's just a charger).

perfect, get a whole bunch and we'll have potentially compiled a network of thieves without their knowledge

do you think enough people are opportunistically malicious to form a reliable mesh network of jerks?

> I ended up choosing the Allwinner A33; it’s an older MPU that came out in 2014. Tablet manufacturers used it in their Android devices, and since Android uses Linux, we should get good mainline support. Not quite. Mainlining ARM chips tend to be a demanding task, and the not-so-widespread A33 is still a work in progress

Do yo know why this is the case? Due to integrated peripherals? Or is there something particularly incompatible about the ARM architecture?

I think there's a fair amount of ARM that's different about each implementation.

eg: early boot - initialization of hardware is timing/order dependent

ARM SoCs are complex and often undocumented to anyone outside the company making them. The arch is fine, but many drivers are needed e.g. for clocks (and a lot of reversing has to be done). Having said that, downstream (Android) kernel will probably be fine for a simple use case such as this

I've always wanted to make something like this, but have it connect to a public WiFi network and operate as a VPN server. Thereby allowing fully anonymous internet browsing. One of many challenges would be getting past the captive portal.

This would in practice be violating the terms of service of the WiFi network and possibly also be illegal?

> Drop one of these in a Mcdonald's, and nobody’s going to expect a thing. You can leave it for days, while it collects data and marshals it back to your home network. brave assumptions. it's will be gone in 30 minutes.

Order two game theoretic trick: fake a main socket device that is in fact a battery powered sniffing tool. Robber may willingly carry that thing in his home.

Earlier quoted context omitted.

With a correctly designed enclosure (chamfered edges, black), it might not look all that suspicious tucked away somewhere charging a phone.

You’d be better off putting a battery in it and dropping it under a bin or something.

That’s going to be way more suspicious that plugging in a phone charger, given the history of bombs being left in trash cans.

The reason why there's a history of bombs being left in trash cans is because it's easy and discrete.

Perhaps a wall-plug air-freshener form factor would last longer?

I wouldn't steal it but I would unplug it to stop the stink. Air fresheners do not.

Why as a wall wart? Odds of discovery and removal are high. Instead fit it into a lightbulb form factor, and replace a lightblub in the restroom. Or you can be SUPER brave and fit it into a wall outlet form factor and replace the whole outlet / receptacle.

Here’s one I made years ago that found its way into a patent application or two.
