This is made from scratch but inspired by TeachingTech design. This is still work in progress.

Mine incorporates 2×18650 cells in parallel to feed 47 WS2812B LEDs.

The size is 225×225mm, the LED area is 222×201mm, the logo area is 212×191mm.

On the rear there are 2 keyholes 162mm apart.

There is ample room for wire spaghetti inside.

I've used ESP-01 with WLED software.

BOM:

• Soldering iron

• Common sense

• 80cm WS2812B led strip

• 134N3P Power bank module

• 2 × 18650 cells

• ESP-01

• 10×15 SPST switch KCD11

• AMS1117 small LDO breakout

• piece of paper as backing or print a thin sheet of plastic

Magnets

You can either use:

• 4 6×1mm mangets for the top part and 4 6×2mm magnets for the bottom part.

or

• use a screw in the base instead of magnets (M3x18mm max with 6x2mm head, DIN 7985 / ISO 7045, DIN 965 / ISO 7046, DIN 84 will work).

Wiring:

The wiring is not too complicated.

First, flash the WLED onto ESP01. Desolder the pins from AMS1117 and ESP01.

Solder a bridge or a resistor (any value above 1k and below 1M) to the ESP8266, from CH_PD to 3V3 to permanently enable the chip.

Connect the 2 18650 in parallel, and lastly connect them to B+ and B- of 134N3P.

Finishing:

I suggest to spray paint the top to minimize the translucent look.

Updates:

• Added a small lip to support the frame and prevent light bleeding through
• Added a hole for whole lenght to mount feet
• Added clips and a channel for led strip (not tested if it fits)
• Added preview video
• Added wiring
