A fully functioning Harley Benton TE-20 BK Standard Series Electric Guitar professionally customised to incorporate a LED infinity mirror – purchased brand new from the Thomann online store specifically for the modification. The black guitar body is precision milled using a CNC machine to create a semi-hollow body whilst the depth of milling is minimised to retain the body strength when under tension by the strings.
There are two CNC milled acrylic mirrors fitted inside and on top of the semi-hollow body. In between the mirrors there is a RGB LED strip fitted around the inside perimeter of the semi-hollow body, held in place by 3D printed black PETG grips. The top acrylic mirror is removeable, allowing access to the plug-in RGB LED strip if required.
The robust modification allows for normal use/playing of the guitar with no extra connections (e.g. USB or external power supplies).
The back of the body contains the housing for the batteries and the electronic control circuit board. Both are enclosed by a 3D printed black PETG cover. Access for inserting/removing of batteries can be achieved via the sliding ‘maton design’ red logo cover.
Each individual RGB LED around the strip contains a red LED, a green LED and a blue LED. When all red, all green and all blue LEDs are chosen to light up (making white light) a good brand of four 1.2V 2500mAh NiMH rechargeable AA batteries will keep the RGB LED strip lit for up to 3.5 hours.
The RGB LED light strip is controlled using the keypad (CR2032 battery powered) which is held in place with a 3D printed black PETG surround fitted to the back of the guitar body. Here is a summary of the keypad buttons:-
MODE button:- allows one to cycle through different animations e.g. lighting continuously mode, gentle fading effect mode, flashing effect mode and ambient sound to light mode. Press once or twice or three times etc…to cycle through these modes.
SPEED-/SPEED+ buttons :- allows one to change the speed of the above animations. Press once or twice or three times etc..to vary the speeds.
MUSIC button:- press to turn on the internal microphone for ambient sound to light mode (Alternatively use the MODE button to turn on this mode).
FIFTEEN COLOURED buttons + ONE WHITE button (W) :- Press any one of these buttons to change the LED strip colour.
TWO BRIGHTNESS buttons :- One button turns the brightness up, the other button turns the brightness down.
ON/OFF buttons:- Turns on or off the led strip.
The internal electronic control circuit board has minimal guitar pick-up interference; the RGB LED strip can easily be programmed on-the-fly via the keypad i.e. static RGB colours/ fading between colours does not cause any interference when the guitar is played through a guitar amplifier (however, a slight ‘clicking’ can be heard when the RGB LED strip is programmed to strobe/flash on-off due to the fast switching transients).
The infinity guitar could also be used as decorative wall art in a shop, restaurant etc…e.g. with a little soldering and basic electrical knowledge, one could further modify the guitar to run off a d.c. 5v power supply instead of batteries.
The guitar weight is approximately 3.2Kg (was 3.3Kg before the mod).
