Until recently, I was using cell phone displays in my hobby projects.
But now I have received the bigger screen, which is almost 3.5 inch and has 320×480 pixels resolution and a touch sensor.
Since the LCD requires 3.3 volts and 16 data lines, I could not connect it to Arduino, so I got my Stellaris Launchpad board and connected display with it.
Quick search on the internet revealed, that we already have excellent UTFT library for various graphical LCDs and moreover, it is already ported for Energia IDE.
So I have downloaded that, and run one of the examples to check the display.
My Linksys WRT610N seemed to be almost dead in peripherals.
I’ve decided, that I have nothing to loose and performed hard reset.
After router booted up, I have reconfigured it manually and everything worked perfectly: internet, even both Wi-Fi interfaces.
Had to dig internet a bit to recall on VPN configuration, but eventually VPN works also.
My guess is that during power loss occurrences the voltage from power supply felled too slowly and that lead to flash memory corruption where the settings are held.
Implicitly it is proved by the fact, I have switched electricity many times off and on just previous two days before failure.
Now I am without internet.
It has failing Wi-Fi second channel some time ago in the beginning of the year.
And today I have checked the VPN and it did not worked. Checked the dashboard and found out, that USB drive did not mount.
Have tried to mount it by hand, but even could not get USB core driver to work.
After reboot the PPPoE internet connection also failed.
So I suspect either router processor has issue or the power supply.
Eventually decided to change the ceiling light fixture in the room.
The difference between new and old fixtures is that the latter hangs on ceiling hook and the new one should be fixed with two screws.
I have checked the ceiling wiring, and also have drawn the whole flat schema.
Started to drill the holes for screws. The first hole went well, but the second was the pain. Other side of the ceiling from the hook is totally plaster :(
That wouldn’t be a problem, if I hadn’t to hide the hook and the wires.
So I had to put the new fixture aside and to start thinking about two possible solutions:
- hide the hook and the wires with the wiring box, and drill the holes for fixture a bit farther
- cover the plaster part with some wooden or plastic plate and screw fixture on to the plate.
