Hey SkyBreaker Club!

Just an Express Update on where we stand and where we are going next. In short: I have finalized the BOM, ordered and received the parts & ICs needed to put a prototype together, measured the current and freq, and got most of the C code tested and ready. We are full mode RGB at 168Mhz! Next: Get the schematics sorted, route a PCB for the controller and modify the controller's enclosure to house the new kit (wiring, strain-relief boots, ect etc).

Following the DIY theme, here goes some visuals of how its done at my end (between coffees and cheese, obviously!):



^ RGB leds are fabulous, couldn't more be happier how this turned out. Since those are custom they fit perfectly
within the mounting heat-sink also.



^ ICs, breakout pcbs, and passive many other good stuff (not shon in this pic). All goes to show how those sort of
prototypes start-up from ground zero, to a functional product.



^ Breadboard all wired, decoupled supply if coming from the debugger so no fuss here. Just getting the ICs ready
so we can write the code for them.



^ Writing code, some nasty time consuming stuff, particularly the SPI Flash IC that we'll use to store colors in memory.



^ Sniffing SPI traffic on the scope. All about clocking and piping the right bits & bytes streams to and from those ICs.
Features of today's ICs are pretty wicked and advanced, so are their precise timing requirements :/


Long live Coffee! I'll update as soon as new development comes in!
