Aliexpress is famous for featuring the newest products/ICs when it comes to electronics but finding those can be a bit difficult. So I tried finding the hidden Gems not only electronics related but in general what I think could be useful. Let's get started!

    Whats real scary to me about the horrible battery casings on the gloves is how they're marketed for skiing.

    Since 2015, I've had that fingerprint sensor installed on my front house door that has been working pretty well. Recently, I came across another fingerprint sensor, the FPC1020A, which caught my attention. Not only is it faster than my previous sensor, but it's also much slimmer in design. Additionally, I was impressed to hear that they claim to have a false rate of only 0.0001%. Overall, I'm excited about the potential benefits of upgrading to the FPC1020A and wanted to share my experience with others.

    • @alexandrezani

      I don't know what your threat model is, but I want to note that because the sensor does the authentication, someone could remove the sensor and simulate an authentication signal. (Obviously, it's not a big deal for the average home owner, but just in case you happen to have reason to worry about more sophisticated attackers.)

      @alexandrezani ปีที่แล้ว +1

      @@elek101 Right, my point was less about encryption than about where authentication is performed. Wiegand systems will usually read your card and send the contents of the card to the controller which decides whether the card is valid. That is subject to a replay attack, but you need to know the content of the card.
      With the above fingerprint sensor, the sensor has a fingerprint database. It checks your fingerprint against its database and sends the user id of the authenticated user to the controller. Without knowing anything about the user's fingerprint, you can just send a user id to the controller. I think the user id is 32 bits and sequentially assigned in the database, so it's probably not very hard to guess it.

    Aliexpress is great for smaller things that you can't find locally or on some more popular stores.
    I ordered 2 M.2 ssds from Amazon, only to find out that I didn't have any screws to screw them into the motherboard. Everywhere I looked, I couldn't find those exact screws.
    Then I found them selling M.2 heatsinks for really cheap, and they came with the screws and a small screwdriver. That was a great deal for me since one of the SSDs didn't come with a heatsink, anyway. It cools the SSD almost as well as the one with the official heatsink.
    I was hesitant about buying from Aliexpress at first, but it's great for such things, just always take a closer look when you're buying something, because it isn't as well regulated as some bigger stores.

I have had a few issues with products not being as advertised or damaged and Aliexpress stepped in and gave me a refund for them, but for the most part everything is fine. The best tips are if it is something of value make sure the store has been around for a while and has good reviews or are a manufacturers own store. A lot of the cheap stuff you can get locally you can get even cheaper from aliexpress since there are companies that just buy that stuff in bulk from china and stick their logo on it and then charge a huge markup on it.
      Aliexpress vendors sometimes have local warehouses too. When I bought my 3D printer it would have been £30 to get it shipped from china or free shipping from their UK warehouse, I have bought filament from a UK warehouse too and it comes in a couple of days.

    Something really interesting can be made with these fingerprint scanners that i couldn't find in commercial products (That don't cost a house payment) is centeralized fingerprint recognition.
    Basically instead of adding the fingerprint on each fingerprint sensor you take the hash of the fingerprint and send it to all your IOT with fingerprint scanner and add the hash to the Fingerprint sensor memory.

    To be fair if the glove batteries each have its own charging BMS board, there is no issue with "parallel charging" because each battery is charging independently. The light on the charger might change when power draw is low/high indicating charge complete, disconnected or charging. My escooter charger does this.

    Another use for the USB isolator: Laptop USB port 0v is often referenced to earth. Since some equipment either needs to be floated from earth, or it is referenced between +v and earth, you want to isolate the USB port to prevent damage or shock hazards.

    Question about the glove batteries: wouldn't parallel charging only be a problem if the batteries themselves didn't have a charging ic like the tp4056? Looking at the video the power supply looks like a dumb switching supply for likely 5v, so it would only make sense to have a charging ic inside the battery itself. Could you clarify that?

    The problem with the self contained fingerprint readers is that they just send a confirm signal to the controller making them vulnerable. The reader can be removed from the installation and the wiring tapped. Any device like that should ALWAYS have two parts, an internal and external unit. The external unit just sends the raw data to the internal unit which then figures out if the data is good or not.

    • @mabakalox2353
      @mabakalox2353 ปีที่แล้ว +3

      raw data sounds not safe either, easy repeat attack, better approach is only internal unit which, ideally allows loading custom asymmetric keys, or at least manufacture trusted one for singing payload, that way any external unit might be used (like arduino) which needs to store only public part of key for signature checking and validating id of payload (repeat attack protection). And depending how paranoid are you, some tamper protection could be added to finger print sensor to prevent stealing of private part of the key.

    • @spudhead169
      @spudhead169 ปีที่แล้ว

      @@mabakalox2353 Over engineered solution. Repeat attacks are easy to defend against. For brute forcing you just introduce an enforced delay between scans. For data repeating, you hash the data from the sensor scan and keep a log of previously used hashes. Then just check to see if a scan produces the same hash as a previous attempt and if so reject it. Fingerprint scans should never be exactly identical. You could also use a simple GDO counter. Both units have a PSK the sensor encrypts its counter with the PSK and the lock decrypts it, then checks it's a value higher than the last successful scan. Data repeating would then not work and without knowing the PSK you can't manufacture a fake scan even if you have a dump of a successful scan. There's no need to go jumping into RSA.

    and 1.5kV is same as previous but includes PCB and power module*.
    *those modules don't like long term DC bias, but it'll save your PC from a HV fault on a USB device, by going up in smoke if anything.

    A word of warning. Check your local electrical regulations before installing that DIN rail remote switching unit in a mains breakout panel. It would almost certainly not be legal to install one in a UK Consumer Unit as there are some fairly strict requirements, especially over unit testing in combination with other permanent wiring devices, which basically amounts to not mixing and matching from different suppliers.
