Dude, this is awesome! Glad you made the project and enjoyed it. I like the choice of the filament it looks great!

Good catch! Just updated it

I love it! Great project, thanks for sharing. I might have to make this, I know my dog would have alot of fun with it

Thanks!

Haha I dont know about genius... but thanks!

Wow, I am blown away. This is awesome, great job!

Yea same problem here! I kept retrying but eventually just gave up lol

I do not understand chinese but I will try my best here. Google Translate: Hello, how do I compile things all the time, both libraries have been added. Answer: If you are having issues compiling the code then I would make sure you have all the libraries properly installed and also have your Arduino IDE pointing to the correct port that your arduino is connected to. Hope this helps!

Lol this is great!

Whoa! Awesome, makes me happy that you decided to make it!

Haha I already posted it!

Thanks, I used Fusion 360 for the design and for the electronic schematic I used EasyEDA. They are both free for hobbyists!

It is definitely possible since you can buy one online. They are fairly expensive though so the sensor is likely of much higher quality. The one used in this project is pretty cheap.

Haha but where is the fun in that? You can buy nano clones or build your own PCB with atmegas if you really wanted it to make it cheaper. This project is more for fun and the joy of building something yourself.

Great case design!

Great project, Haha I saw your post on r/arduino last week and commented that I liked your design and wanted to make my own. I ended up making my own 3D printed version and made an instructable too. Thanks for the inspiration!

Yup, the tare feature was a last minute addition so I used a momentary push button. The part numbers are just the default that EasyEda uses when making schematics, sorry! The on/off switch is a standard switch (Not momentary) that you can get on amazon. The YouTube video should show you how to install it. Let me know if you have any other questions and have fun building!

Haha yup, I posted it over there. Thanks!

This is great! I love the design

It's been accurate for me well below a gram. You can also swap out the 5kg load cell with a 1kg or 500g load cell for more accurate measurements. The type of load cell I used can be bought in different configurations.

Good catch! I'll fix the schematic when I get time.

A wood one would look really cool but difficult without a CNC. If you are thinking about getting into 3D printing I would recommend checking out your local library or makerspace. That way you can try it out without investing too much money in a printer.

I used a 10k resistor. Maybe I will add links on my next instructable!

This looks awesome!

This is great! Just like a mini industrial pick-to-light system!

Awesome, I am happy you like it. I have heard makerspaces are great but if you are just looking to get into the hobby your local library might have a printer and maybe classes as well. Keep me updated if you decide to make it and feel free to reach out if you have any questions!

I am definitely going to be printing this, this is awesome!

Good thing I have an electrical engineering degree:) But seriously this project was just meant for fun and obviously not to safely store real valuables. Everything is made from plastic lol

Good suggestion! I remember doing a quick Google search for mini RFID tags and all I found was an Adafruit one for $3/each. I didn't feel like buying one so that's why I decided to just remove it from the keychain. $1.50 for ten of these adhesive ones sounds like a great deal. Have you used these with the RC522?
