yep coming soon™
not really… the chip + LED + crazy amount of inductance required means a very difficult time making these things work together inside a tiny glass tube.
yep… multi-color xLED (no chip) in LF and HF coming soon™
not really customized… each color LED requires a lot of design, engineering, and some trial and error to get right. this is due to the fact we are using the capacitance of the LED module itself as part of the L/C circuit, but LEDs are not sold with capacitance being considered important information, so you don’t even get that information on data sheets for LEDs… and also, because it’s not considered an important aspect of component design or engineering, you can get huge variances on capacitance values per component. There are no tolerances offered or documented for the capacitance of LED components… it makes including them in these types of designs very difficult, so we work hard on specific colors from specific manufacturers and once we sort it out we attempt a production run and filter out the under-performing ones… basically.
