This test board for the micro-readerboard has the 17-segment LED display (socketed) on one side, and a 20-pin DIP ZIF socket on the other side. This allows one to quickly swap out the chip, and to swap out the display if needed. A 2xAA battery box powers the system.

Seen Here: The PCB out of the bag!
So, today my PCB for the LED matrix arrived from BatchPCB! For what I paid, the PCB arrived fairly quickly - I ordered it on the 15/02 I believe, and it arrived 11/03 -- 26 days, which is pretty good (they state 19 business days).
The quality is very, very impressive - far better than anything I could pull off at home. The silkscreen and soldermask makes it look really nice, too.
Soldering it was a joy, although there was a LOT to solder and it's all surface mounted.
I had a few problems at first; it wasn't lighting the matrix at all properly but I soon realised with my new design (transistors on the cathodes) I have to write the transistors HIGH to get a LOW on the cathode, so a quick line of code changed to get that working.
Then for some reason the top half of every letter was flipped. It turns out this was my fault: I messed up when making the package for the LED matrix in Eagle, swapping the matrix's 5th cathode for my system's 8th, 6th for 7th, 7th for 6th and 8th for 5th. This was fairly easy to fix in code, however.
Finally USB isn't working to program or communicate, but I can configure the FT232RL chip (after all, it's sending the clock pulse that's driving my ATmega168). I think I have an idea of what's causing this, but I'm not sure yet.

Du behøver bare en app på din Smartphone og Philips nye LED-pærer, så styrer du selv lyset i huset. Philips lancerer i dag ’Philips hue’, som gør det muligt at kontrollere belysningen i hjemmet trådløst fra en Smartphone eller tablet. Løsningen sælges eksklusivt i Apple-butikker fysisk og online fra i dag.
The RGB LED is successfully fading into one colour fast and then slowly fading out of it, waiting a random amount of time between flashes.
All that's left for the code is the light-sensing part so that it will only activate in dusk.

Inspired by looking up on Internet at beautifully made Scurion lights I made my new helmet light yesterday. Powered by 7.4V 1800mAh Li-ion pack it gives 70 or 120 mins burntime. Diffuser is optional but I like yo have it rather than spot. 5 modes from bright to part power to 2 modes of strobes. It is not intended for deep diving but could easily hold 20m depth. Light cord is adjustable for belt worn canister option and it is an umbilical rubber tube with signal cable (has a non-conductor steel wire for strength). 5x3W Cree star LED assembly from China (DX#35241) claimed to have over 1200 lumen luminosity. In fact it is comparable side by side to 10W HID light. My redneck replica of Scurion is made of stock 2" pipe s40 PVC and aluminum) and other parts found in Home Depot. LED was about $30 and was long time lost piece in my garage mess. Cable glands are bike check valves sealed thread with teflon ( valve core removed).
#LED #Panels can be installed in big spaces like corporate offices, as they provide the brightest quality of light.Visit : bit.ly/1tpRDiu

Close up look at LED flash light head. Angled the light to create the abstract look.

We created this image to show the someday, incandescent lighting may be extinct, since LEDs use less energy and last longer and are better for the environment. So we used the world's lightbulbs for fun things like windchimes, wine bottle stoppers, and bobbers for fishing.
