When I saw This Lamp for children, I had no choice, I had to buy it and to transform it.
The result is a Led Matrix Beamer that can display Messages and Pics from the Internet to the wall.
I think after a few more changes, it will be a nice Alarm Clock controlled over the Internet.

Last night I wrote a little script to show that my beamer is the perfect clock projector.
You can display 2 numbers on an 8x8 led matrix.
Here is a little demo video. The height of the projected numbers were +-50cm and they are very good readable
Hi all.
I used this 8x8 led matrix, because the leds are flat with a diffuser and well separated.
If you use normal Led's, they have already a lens, and together with the optic of the "Sprida" lamp you will not be able to focus them and all the led dots are overlapping.
First of all, take it appart. Remove the led from the tail.
The 8x8 matrix modul with the Max7219 connected to the Pi Zero.
This 8x8 module is perfect. Because of the leds. The are flat with a diffusor and well separated, so that you can beam single dots throught the optic.
Glue the matrix on the holder for the color sheets of the lamp
Slide the the sheetholder with the matrix upside down in the sliders.
With hot glue fix the pi zero on the bottem.
Cut a long usb cable and pass it through the hole of the lamp tail. Make a node in the cable as cable relief.
Solder the cable together again.
Hot glue the Wifi stick with the ogt cable in the body of the lamp
Ready to rumble
Your project inspired me to make this.

Wow, looks great. I also tried first a Led watch, but mine was not bright enough, so I used the Led matrix :)

This almost makes me want to take apart the LCD screen of my ESP WROVER Kit, and slap that in front of this exact light. I bet that could even work out really well since it's an RGB LCD!
Also, why'd you decide to go for the Raspberry Zero? It does work well, but is also a little overpowered for such a clock ... Right? >.<
