  • Those hardware generators you mentioned have been around for at least 30 years. A TOTP app is just software that does the same thing as those hardware generators.

    I’m aware, but you’re not getting the secret token that you’d need to put into your TOTP app. At least not that I know of. I also haven’t checked in a very long time if there are open source reimplementations of the photoTAN apps. They all got their own flavors, but it’s also just a slight variation on a theme (initialize app with qr-like secret, then scan a similar code as a challenge/response using that secret to generate token). Probably should check that at some point.



  • They aren’t forced to lock them down, or prescribe any app store afaik. That’s the banks that do. Some lock it down, some not at all. But you’ll need some form of 2 factor “photoTAN” app. Unfortunately, common 2fa codes aren’t used (or allowed), I think this legislation is actually older than them becoming common.

    And that’s quite all, they also offer hardware token generators. Not sure if they are required to, but i think so. You do have to pay for them once (20 or 30 bucks maybe?). In reality, this is somewhat impractical for a variety of reasons…





  • Sorry but the theoretical price of cells isn’t relevant to the consumer. The price of products containing them is. This thing costs currently on the official site 900€ (with some sort of sale going on). The Elite 100v2 with comparable capacity, but using LiFePo4 (included in the same current sale) costs just 550€. To add insult to injury, it also outperforms the Na model in nearly every aspect except sub-freezing performance (where it at least still works, but nowhere near normal spec values either). This includes an abysmal solar charging efficiency for the Na of roughly 50% at normal temperature. Somehow.

    Again, once the price reflects the cell cost, this could be a very attractive option. At the moment, unless you’re into camping in sun-zero climates, it’s just a very bad deal.

    Edit: to be clear the Na model also doesn’t have a better life expectancy, not according to the spec. Both models are specified to “over 4000 cycles”, not there is no percentage threshold specified for the Na model. The LiFePo4 model includes “to 80% capacity” in that definition. If this is specified somewhere for the Na model, I can’t find it.


  • The thing currently costs at least 50% more than the closest equivalent LiFePo4 from the same brand. The only real advantage seems to be it’s ability to handle sub freezing temperatures, but usability still drops dramatically (both capacity and available power delivery). Everything else is straight up worse in this one in direct comparison.

    It’s only the first product, so it’ll most certainly get better. Also as numbers of products sold rise, costs fall. Once these are cheaper, that are a real choice.






  • The critical thing with these is response time. If it’s even slightly too high (I think 20-30ms is easily too high), some/many people get very motion sick. Getting that time down as low as needed is also not trivial.

    With it only being 60 Hz on the controller itself, that’s basically impossible to hit. That’s 16.6 ms already. Then the processing, sending to the PC, and the PC reacting has a budget of just a few ms? Yea, not happening.

    I’m assuming he’s really not sensitive to this. As it’s open source now the people who are sensitive can improve it. That’s the beauty of open source after all.
