Camera and audio HAT are working, only audi amplifier is missing. I'm trying to work on the laser, i'm not ease with welding on pins. Have you some suggestions ?

Have a great day !

I also made a full video showing the build and the final result: https://youtu.be/48Dy4z7UFhk?is=xiCivoHYjwZXzatD

Here It Is, I wanted a super cheap solution for who wants a diy night vision instead of buying some NVG that give almost the same results but cost 5/10 times more.

I made It with 75€ (83/85usd?).

I designed and 3d printed all the enclosure and various parts, as the wilcox mounting. What I bought are an IMX sensor from ali (40€), a cheap lcd from an old camera (you can get It for 15/20€ from ali), a plexiglass lens protector from ali (5€) and a 3x zoom Lens from ali (8€).

The weight of this Is under 250grams and It uses a 11.1v lipo/lion battery, the length Is 180mm with the eye gasket on, 145mm with the eye gasket off.

It works with analogic signals so it has an almost inexistant input lag (10ms).

It handles well little light and clear night sky conditions, so I suggest an IR 940 Torch (20€) so you can see in total dark conditions too.

This Is a pretty nice experiment that can be upgraded to Thermal Imaging in less than a hour, so with a Total of 200/300€ you can compete with way more expensive solutions like some analogic NVG's without breaking the bank.

It took a lot of effort so I hope you enjoy this summer project :)

I did all the soldering! I did have a very experienced quad builder next to me walking me through it though. Let me know what you think! I’m pretty psyched to have gained this knowledge especially because it was wayyy easier than my jock brain made it out to be👽

I built a full working Solar PA Music Speaker,

66€ Solarpanel 100watt

0€ old MDF wood

0€ small speakers

10€ Subwoofer

0€ (24€ but for free) class d amp board China 200watt

Works with xt60 plugin and 5-26 Volt

So you could use any dc from 5-26 v

And it works with this solar panel without any accu

hello guys, i just created a cubot (same as the emo, but different function) it has temperature and humidity sensor. what is exciting about here is the mood of this little companion depends entirely with the temperature (weather) so far, his mood is always happy.

Just need to finish the trigger

Built using :
- 3d printer (PLA)
- plywood
- rods screws and aluminium tube
- arduino and 3 potentiometers + mobiflight

My daughter used to ask me 20 times a day to play different songs. Sometimes I would get the same request like 5 times in a row. Taking the phone out and finding it on Spotify was annoying, as it was distracting her and driving attention away from the music.

So I've built BailaBox. A music toy that lets her play the songs she wants when she wants.

It's an RFID-enabled, ESP32 toy that connects to my home network and, through Home Assistant, plays music on network speakers (in my case, I'm using a Sonos system).

First, I made a breadboard prototype, which was a nice proof of concept. But it was not very child-proof. So after some improvements, I've made custom PCBs - one for the power supply and battery charging and another for the RFID reader, ESP32 control, LEDs, buttons, rotary encoder for volume control, etc. There's also a custom enclosure for the project that I 3D printed.

The toy works with NFC tags. I'm using sticker tags that I embed inside 3D-printed tokens that contain magnets. This allows for auto-positioning on the RFID reader area (there's a corresponding magnet in the enclosure as well). To make the tokens recognizable, I print and cut custom stickers that represent songs.

I have a bunch of tokens with different songs now, or whole playlists. One could also add audiobooks, sound effects, or even full smart home automations (like, for example, a bedtime routine) as BailaBox connects to Home Assistant.

If anyone is interested in replicating it, I've made a GitHub repo with project details. It's my first attempt at custom PCBs, so I'm sure there's a lot to improve, but this version works as intended! So have a look if you are interested; let me know if you have any feedback or questions.

Hi guys!!! I’m having a lot of ideas about Gadget, so I thought…Why don‘t us fans have cover cases for earphones? so I thought of these two designs :3 ik it’s not perfect but I’m considering on making these with rubber or Silicone or something like that, would someone be interested in a finished version? :)

(the first is supposed to be a hat where the top part opens and closes and the second one is Gadget’s telephone secret hand)

This display features a 6.2-inch large screen with a resolution of 480×1280 pixels. The interface is divided into three sections: the left side shows a compass, the center section provides a switchable display area, and the right side displays GPS data.

The system uses a 10-axis IMU sensor as the attitude data input, along with a GPS module to acquire information such as latitude, longitude, speed, and altitude.

More testing videos will be uploaded soon.
