DIY Soldering Practice Kit RGB Practice Learning Electronics Training Board...

This went together really well. It was good practice because it has few components, but many big soldering points. In the end you make a fun little widget "colorbuilder" The end product could be a good tool for an artist, like a jeweler or designer, or one who needs access to a color spectrum for conceptualizing ideas.

I was kind of excited to get this little gadget because I have always been fascinated by the fact that you can 'combine' red, green and blue light and end up with white light. I assembled the little gadget and plugged it in. The red and blue LED's work just fine, but the green LED does not light. Kind of a letdown. I realize that in electronics, there are the occasional defective component, so I don't hold any bad feelings toward the seller. I was actually pretty impressed by the overall quality of the PCB and the other parts. It is a well built little device. I just happened to get that one defective part... luck of the draw, I guess. Don't let this review keep you from buying one for yourself, like I said, I just happened to get the one with a defective part. I still want to see the thing work like it is supposed to, so I'm actually going to order another one! Have a great day y'all!

Excellent transaction and shipment. Good with spectroscope to understand emission and absoption.

I was lucky to start with this project. it's simple and fun. I still play with it. it's like the color picker in photo and drawing software but in real life. lots of fun

There were not any instructions for this. Which would help a complete beginner. Otherwise really simple to assemble. Four components, three of which can only be placed one way. Only component that would give a complete beginner any issues would be the light. But if you pay attention on the board it tells you where the negative pin goes. It's the one that isn't like the others. The USB power cable is pretty easy to source. Probably have a couple in the house already.
