Dull LEDs aren't cutting it.

A project log for NIRGM - Non-Invasive NIR Glucose Meter

Uses different wavelengths of light to shine through the skin in order to determine the amount of glucose present in the user's blood.

Realized that I should have(a long time ago) ordered some high quality LEDs. The standard inexpensive ones I always get are not cutting it. Did a brief search on Digikey and found some serious ones for the job that should be a lot better and also are still 0603 so no need to order a new board.

The IR and the NIR are already powerful enough I hope.
