Introduction: Acrylic LED Pendant
For this years Helle-Koepfe workshop we simplified the last years nametags.
Again we use the lasercutter to work with 2mm acrylic. A 3mm LED and a 2032 coin cell is used to enlight the pendant, and a simple string is used to wear it.
Step 1: Production
Making the pendant is pretty streightforward: Each kid could write their name on the pendant in the svg file and chose a motive, which is then cutted out with the laser, motive and name are either engraved or marked. Thereafter, the backside protection foil is removed and a led inserted into the small hole.
The legs of the LED are then bend to reduce their length and a coin cell inserted into the big hole. A strip of transparent adhesive tape fixates the legs on the battery and guarantees contact.
A piece of string through the upper holes completes the pendant.
Done and Enjoy!
What laser settings did you use for engraving the acrylic to that nice frosty finish?
Use cast acrylic (compared to extruded) to get a frosty white finish. I use 81% speed and 40% power with my 45watt engraver.
I'm not really sure what to use with a different laser cutter, i just used "engrave" in the VisiCut control software with 100% power and 100% speed for the laser cutter, the frosty finish happens i think by chance through the pulsation of the laser and the resulting uneven surface
Yay!
