Fiber Optic LED Lamp - 10 x 11 LEDs

This is a remix of the great model by andrei.erdei but with multiple changes, the biggest of which was making the lamp the absolute largest size possible to still fit on the print plate of the X1C. It is not dramatically larger than the original, but it is definitely noticeable and allows for slightly more flexibility with WLED effects than the original. This model accommodates 10 LED's vertically and 11 LED's horizontally, so a total of 42 LED's, giving 10 more LED's than the original model which was 8 per side for a total of 32. The difference in numbers between top/bottom and sides is not noticeable in use.

Besides making the lamp bigger, there a few more modifications to the original:

• The base has been extended to fit the legs on the wider lamp
• The base has had the raised area for the processor removed with a negative part
• The base has the hole for the pushbutton filled in with a positive part and the holder for the pushbutton removed with a negative part
• The hole for the wiring from the base to the lamp was enlarged on both the base and the lamp body with negative parts
• A hole was added in the rear of the base to allow the use of a DC power plug that is very handy if you want to use 12VDC power supplies like this
• The base now allows for more room to use a Buck Converter if you want to use 12VDC LEDs which will allow you to lower the output voltage to 5VDC to run your ESP32 or whatever board you choose to run WLED
• I used 6 walls on the body to make it much stronger, but you may want to reduce that if you don't care about strength

The lamp is designed with 3mm holes to use 3mm fiber optic cable which is readily available on Amazon or AliExpress. However, in my experience, the fiber is not very consistent in diameter, which can make inserting it into the lamp very difficult. To help make it much easier, I used a 3mm (can also use 1/8") drill wrapped with many layers of cloth tape to make it easy to twist between my fingers, allowing me to open the holes up a bit to make it much easier to insert the cable. You can definitely use a dremel or drill to do the same thing, but keep in mind that you want to keep the hole to a tight tolerance as the fiber is held in with a friction fit - make it too loose and it will fall out…

Overall, this is a very fun project and the effect is pretty cool - there hasn't been a single visitor to my home that has not commented on the lamp, and they make great gifts. :- )
