This is the first project that let me play with something different than mere fimware and PCBs, but finally a bit of boxes and acrylic planes. It is a multicolor lamp, which is developed 100% from scratch, both firmware and software, for a challenge and for seeing how things can be optimized with standard code and a new concept of power handling. The LEDs are also implemented in a 100% self-developed thermal PCB because there were no other little boards available with a given density in terms of power LEDs per square inch.
I started to build some LED drivers, then a small MCU board with a power path handler, with a built-in safety feature of power priority in made in hardware and other short circuit protections, since it is supposed to deliver more than 10W. With these loads, one need an high energy source and so a bit if protection never hurts. Those boards are Lino and Glighter.
At the end, it turns out that I can use those boards together, with additional PCB for connecting the LED and with some thermal handling, to build a first draft of my desk/ambiance lamp. In the log will be present some eventual progress on how things are going.
I will keep the updates in the log as soon as I have more details ready to be published.
