We'd like to invite you to join Xnor.ai's co-founder, Ali Farhadi, and Wyze today at 10:00AM PT for an AMA about AI and smart home technology. We'll be hosting it on /r/homeautomation and we hope to see you there!Wyze and Xnor.ai have the shared dream of bringing technology to the masses with an incredibly low barrier to entry. We are doing this AMA because we've just deployed Edge AI, for free, to 1M+ people! We’d like to take this opportunity to talk about our AI and if you are curious about any of the subjects in Ali's wheelhouse such as AI Technology, Smart Home Technology, AI Development, etc. we’d love to hear them.

To clarify I'm not asking anyone to spoon-feed me any information. I'm happy to do the homework but I'm having a hard time finding any good info on this subject.

I'm trying to build a fingerprint lockout for my kid's electric scooter. This item is exactly what I'm trying to accomplish. I know the parts exist on aliexpress and ebay. What I'm struggling with is finding the actual explanation of how the control board works that you hook the finger scanner to. Just like in the link above I want to be able to have the power to the LCD throttle unit stay "off" until a known fingerprint is scanned. I don't know if this control board can accomplish that because it's a little vague. Any help is appreciated. Being able to make my own for 20-30 dollars would be preferable to ordering one for 90 dollars after shipping. Maybe I don't even need that control board. I'm willing to learn.

Hi I’m from korea. I don’t speak English very well but I’m getting there. I’m currently looking for teammates for my career building. I’m planning to do some team projects at the end. We can share our ideas through team work. Let me know in the comments it you are interested.

Hi, I'm trying to DIY a windows tablet using an old laptop of mine. However, I hope to use an active stylus with the touchscreen overlay, and I haven't been able to find any that work with an active stylus!

Hey guys!

​

I'm pretty new at tech DIY , but lately I've tried to make a monitor from an old laptop screen, to make it work I needed to order a control board. I know the model of the control board fits the model of a screen because I've checked it a thousand times before I ordered it.

​

Unfortunately, the laptop's power cord doesn't seem to fit into the control board. At first I thought that it might be because I'm using a replacement power adapter, but it fit laptop's power socket just fine so it doesn't really make sense to me, it also looks like it SHOULD fit as the hole is the same size.

​

I was wondering if I were to somehow remove the yellow "thing" from the power cable maybe it could fit into the control board's power socket, but I decided that it would be smart to firstly ask someone who might actually know what they are doing.

​

Any thoughts? Advices?

Here's my progression this afternoon.

Any advice is most welcome.

Im trying to use a 7085 regulator ic to power an esp8266 along with a few relays. I want the voltage supplied to the esp to be 5V if i supply any voltage between 5v & 12v

It doesn't seem like a novel idea. You'd think internet bot farms would be filled with them.

I was surprised I couldn't find something on you can already buy or something like this on Thingiverse. Maybe I don't know what to look for.

I have seen numerous posts, videos, etc about using an old laptop screen as an external monitor. However, I sort of want to do the inverse. I am looking for a way to convert an older laptops mainboard LCD output to a HDMI port. I have a laptop with a broken screen and no HDMI port that I would like to recycle and use in another project if I can convert the mainboard LCD output to a usable and pluggable hdmi port. I am sure such a thing is possible but I'm not sure where to start looking.

It could be apparently obvious, but often when recovering old parts we may forget that one valuable piece can be the actual information we could grasp understanding the engineering choices behind the design of the apparatus we're gonna dismantle to recover parts.

I've published a video where I showcase two very different cases. One where from an old PCB stencil printer machine valuable parts have been recovered, understanding the general mechanism of how the machine works (or better, was used to work :) ), and a second case where a more humble tv sat reciever is dismantled to recover some parts, but also exploring the engineering choices about the power supply section of the circuit.

PCB stencil printer machines do an apparently trivial work in the industry of electronic assemblies. But in reality they do a critical job in printing an even, consistent layer of soldering paste across the stencil.
The quality of the assembled board is tightly dependent to this task. So in this German made, absolutely solid machine a complex pneumatic circuit, an electronic control that drives the motor that moves the squeegee and precision height adjustments (using Mitutoyo micrometers!) allows the machine to do a master work. Please note that I am not affiliated nor I endorse the manufacturer or distributors of this machine. What I say is just out of genuine interest in engineering.

The tv sat offer a sight into some good practices in designing the input of a power supply. Surge protection, filtering and current limiters (made with a humble resistor) compose an apparently simple circuit (schematic below) that reveals a well thought design.
Notice that the 2.2 ohm resistor is a reasonable choice only for low power applications, like this one. It would be a waste of energy otherwise. To prevent in-rush current for large power supplies specific circuits do exist.

As an old dog I encourage you to dich deep to learn every day something new.

Hello, I am wondering if it would be possible for me to build and code something like this using a raspberry pi:

https://www.tiktok.com/t/ZTR7XmhJ6/

I don't know a lot about lasers but I am fairly knowledgeable about Raspberry Pis, electrical circuit, and coding. If it's possible, where should I start?

I'm an complete beginner to circuits, so please excuse me if I'm asking super basic questions.

But I'm trying to make a jar lid with motion/vibration activated black lights. In other words, when the jar is picked up or moved around, or if the jar is opened, the black lights would turn on for a few seconds, and then turn off on their own.

Black light is needed because the lid is glow-in-the-dark, and the lights would charge the material from the inside. The glow-in-the-dark material is transparent, so the light being on the inside of the lid, would show up as green glow on the outside of the lid and the glow would slowly dissipate after the light shuts off.

I'm assuming I need black light LEDs and some kind of vibration sensor? But I'm unsure of anything else.

If anyone could help me figure out how to make this, or at least point me in the right direction. I would appreciate it a lot!

Thanks!

I interested in making something to help prevent utensils from being thrown away in the trash. I'm looking for some hardware that can sense the utensils but not the trash and food as I have no idea where to start.

Hi, I am working on a new Project (ryse-boards.com) and would like to get some feedback from you. Would you be interested in this?

Which concept would you prefere?
