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!

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 Жыл бұрын

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.)

@mrfrenzy. Жыл бұрын

Yes, there really should be encrypted communication between the sensor and the door controller inside your building.

@elek101 Жыл бұрын

@@alexandrezani Most professional access systems use wiegand, which can also be easily attacked. Encrypted communication is rare.

@alexandrezani Жыл бұрын

@@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.

I would go as far as to say the USB isolator board is highly recommended for beginners on the hobby. I nearly fried the USB port on my work laptop due to a small speck of solder causing a short on my very first protoboard Arduino project. Luckily the laptop had protection circuitry and it only powered off and stayed "dead" for some 15 minutes. I made several beginner mistakes but if I had one of these isolators back then, I could've avoided the momentary feeling of horror. :D

a tip that i have found works wonders... select english language, and not your own language for the website... other languages get translated in a weird way.. from chinese/english-> english(if not already)-> to your language, i never find anything good if i select german but on english i can find mostly everything i am looking for

I would love a video explaining how you isolate and transmit power from one side to the other.

That relay module looks like it has an ESP controller. So it should be possible to reflash with ESPhome or Tasmota to use with home assistant

Great video. It's great to see the LD2410 getting more coverage!

The LL2410B (Bluetooth) version just got added to Home Assistant in either the last update or the one before that. Obviously it works over BT which is why it's required but now that they added BT proxies to HA, distance is no longer an issue as long as you have a spare 3 to 5 dollar ESP32 to make it a BT proxy to extend your BT range or if your HA server doesn't have BT you can easily add BT functionality by adding one as it communicates with HA via WiFi, or Ethernet if you have one of the POE ESP32'S with an Ethernet port. There is a video on here to set it up but essentially you just have to cut a power only USB cable and soldier the wires to the 5v and ground inputs/pins the LL2410B

0:27 sharpening drill bits is nothing weird! That tool seems useful, getting the angle right can be tricky. To be fair though, if you're the kind of user that needs to sharpen his bits it would be very odd to not have a grindstone or band sander, and/or have trouble getting the angle right when grinding/sanding...

Maybe try some smart breakers from aliexpress. There are some that can measure power usage and can be toggled remotely. Seems useful but I'm a bit worried about the safety side of it

Subbed! Definitely trying out the fingerprint reader. I love that your voicing your videos in English as well, however at 11:40 when you say "worked" is sounds quite a lot like "broke", and I was confused until I replayed it a couple times. Great video! Keep them coming!

the recommendation for the human presence radar comes in handy, since i already ordered 4 of them before watching your vid

A challenging task re design the wheel . New style comms..invisible beam, containing origin, destination, arc angle data, bounce off atmosphere back to a calculated relay point on earth, then in a near instant from that point, transmit again toward the final destination using any bounce relay points available .

The "Human Presence Radar" is available for just a couple dollars if you don't include the USB board. Get one with the USB and then get extra sensors to use on your robots and other projects. I think it's a very promising sensor. Thanks for another fun and interesting video.

I've got several of the USB isolators and they work really well.

The grinding attachment you pointed at in the intro is a tool sold at Harbor Freight. Not sure I would recommend it, but its fro sharpening your drill bits. Definitely recommend buying tools from stateside stores though, as the quality of some cant be guaranteed... recall some pictures of tools that broke apart due to being the wrong (cheaper) grade of steel...
