Faceplate issue #1

Jonathan Wilson says (10-Jun-2012):

Hi - I've just received my kit (thanks!) but the faceplate appears to be 
defective with what looks like paint runs over it. How do I go about getting a 
replacement? I can send a photo if necessary.

SW: Countdown display has multi color colen char.

What steps will reproduce the problem?
1. Set countdown alarm CDA
2. Let CTA fire
3. change colors

Colen char ends up multicolor?  May be due to the fact the we are getting close 
to memory capacity.

HW/SW - Unable to program ATMega chip using FTDI-USB Cable

It is not possible to program the ATMega chip using the FTDI to USB Cable.
This problem is erratic, because the programming works sometimes.

It seems pressing the RESET button on the C2 board at the correct time does the 
trick.

Need to reproduce the success / failure mode to verify if this is true.

SOLUTION :
As a temporary solution, use an Arduino Board to program the ATMega and then 
transfer the chip to the C2 board.

HW: Biasing Transistors to increase LED brightness

I used 2N5415 transistors (rated for 1A) instead of 2N5401. Brightness improves 
a bit.

I also reduced the resistors connected to the Base of the Transistor from 100 
Ohms to 33 Ohms. This drives the transistors better, and the LEDs are much 
brighter.

SW: ColorMode is flaky

Color mode should display single digit color_i in COLORS[color_i] (not current 
time)

USB Wall Wart for C3Jr_v2

Christopher Ward says (14-Jun-2012):

I received my C3jr today and it looks great! Unfortunately, the little black 
usb wall charger does not work. I know the clock is working because I can 
connect it to my computer. Thankfully this should be a quick fix. Let me know 
how we can proceed.

HW: Swap INC and DEC locations

Natural location for INC is on the right, DEC on the left.  Only the physical 
locations should be modified.

HW: SP1 pin spacing too big.

Speaker pin spacing on ClockTWO is .3".  Speakers I got have .2" spacing.

Need to re-order or re space.

HW: RGB pads are too close together.

These are too easy to short.  Let's not only make the pads larger, but separate 
them by .1".  This will prevent them from being flush soldered but it appears 
that they were not meant to be flush soldered.

HW-ClockTWO Alpha Board (blank ALL LEDs)

PROBLEM :
1. To blank ALL LEDs, it is necessary to "disable" the Column Driver, IC U4, 
74HC154.
2. The control pins on U4 for this function are Pin 18 (G1) and Pin 19 (G2)
3. HIGH on G1 and G2 disables all LEDs, LOW enables all.
4. Presently, these pins are permanently grounded LOW.

SOLUTION :
1. Isolate Pin 18 and Pin 19 of IC U4 from Ground.
2. This requires a couple of cuts on the solder side, and one cut on the 
component side.
3. Verify with a multi-meter that these two pins are isolated from Ground.
4. Connect a wire link from Pins 18/19 of IC U4 to the micro-controller IC U3 
(ATMega) Pin 26 (PC3/ADC3)

HW: ClockTWO Alpha Board (Power Input Socket J1)

PROBLEM :
1. The Power Input Socket J1 has the terminals inverted from standard practice
2. The center pin is negative and the outer shell is positive
3. This is reverse of what a standard Wall Wart plug config.

SOLUTION :
1. Isolate the GND Pad of J1 by making four cuts.
2. Isolate the V_IN Pad of J1 by making one cut near the pad
3. Scrape some of the solder mask on the GND plane near the V_IN pad of J1.
4. Using an old component lead, create a solder bridge between GND plane and 
V-IN pad of J1.
5. Scrape out some of the solder mask from the V-IN track which goes to diode 
D195 (1N4007)
6. Using a piece of insulated link wire, make a connection between GND pad on 
J1 and V_IN track going to diode D195

HW: Serial TX and RX used for col driver on C2 Board

Serial lines are needed for communication with host pc.  Currently they are 
used for the 4 column driver inputs.

Need to reshuffle routing or add counter chip to circuit.

SW: Col Driver interferes with buttons

PORTD Buttons work fine before lights come on.  Then buttons no longer work.  
PORTD is the same port the col driver is on.

HW: LDR Short Circuit

The LDR is not designed correctly.

I soldered up the circuit and got an repeated auto shutoff on the power supply.

Removing LDR fixed problem, but row driver #2 was fried.

When LDR is in full sun (low resistance) the only thing between VCC and ground 
is a 1K resistor ==> 5 AMPS.

Need to re-engineer this.

SW: SetTime Mode should require fewer clicks

Just use YMDYMS leds to indicate the unit being set. Skip "Y", "M", etc 
displays and go straight to setting.

HW: Speaker rings when LEDs are scanned.

When no sound is intended, the speaker will ring as the LEDs are scanned.

I've tried to mitigate by holding SPEAKER_PIN LOW, or HIGH which helps but does 
not eliminate issue.

Also tried cap across speaker pins, which stops the sound completly (even when 
you want it) or does not help (if the cap is too small).

Maybe we need to play with resistor values.

SW: Potential to burn out LEDs when reset is hit

What steps will reproduce the problem?
1. Any time reset is hit

Should be able to modify bootloader to disable column driver first thing in 
main.

If reset is held down, LEDs can still be burned out.  Should consider HW fix.

HW: Move DBG to Pin 19

Move DBG pin to ATMEGA pin 19. (Arduino digital pin13).

This can share a pin with SCK and SPI still works.  

One minor drawback is that the LED is lit very dimly when SPI comm is active.

If this mod is adopted, it will show when programming is taking place, and free 
up a pin for the proto area.

HW: column transistors are backwards.

On the schematic the column transistors are the reverse from Peggy2.  

I was trying to figure out why the row drivers were not performing very well.  
They seemed current starved when the resistor value was to low.  I tried 
reversing the column transistor on a whim and was able to get brighter LEDs 
without red winning as much.

I measured the current for both as marked on ClockTWO schematic and reversed 
and got 3X more current with transistor reversed!  

Then I tried to understand transistors (to no avail).  

Finally I looked at the Peggy2 schematic, voila.  Our transistors are 
backwards.

HW: ClockTHREE Final Board changes

List out all HW changes required in C2 board for C3 final

1. Invert Power In socket

2. Bigger LED Holes (0.75mm DIAMETER). Stagger in a zig-zag manner ot get more 
clearance

3. ROW Drivers STP16DP06 : Add DIP socket on Main Board, and remove the SMD 
option on Main Board

4. Break Out Board for Row Driver with SMD chip STP16DP05 AND Potentiometer and 
Capacitor

5. rtcBoB : New layout, with only DS3231 SMD chip (no through hole RTC chip) 
due to battery on other side. Select correct BATTERY HOLDER

We want a clean front face.  No buttons.  Just a glossy finish.  This implies 
right angle buttons that can be accessed from the bottom.
