@Max: at 20mA you need almost 10KW of power. That is massive, and requires not only proper dissipation but good power distribution - and note the huge amount of light you'll see. Unless you somehow decide to do some sort of PWM (like 10%) and then you can get below 1KW. Even like this, it's not easy to dissipate and distribute.

Would you class these as adages, aphorisms, axioms, dictums, epigrams, maxims, precepts, saws, truisms, or... well, what?
Here we discover how to use the XADC (Xilinx Analog-to-Digital Convertor) in the Zynq All Programmable SoC to read the chip's internal temperature and voltage parameters and output them over an RS-232 link.
When extreme thermal cycling causes circuit boards and chip packages and the silicon die in the packages to expand and contract at different rates, problems may ensue.
In part 3 of this epic tale we consider how we might use tri-state buffers, leading up to the legendary bi-directional buffer.
Digital engineers are often confused among operational amplifiers, differential amplifiers, and instrumentation amplifiers; this is exacerbated by the fact that their circuit symbols can be similar.
