Wise Clock 4 with ATmega1284

I thought that replacing the ATmega644P with its bigger brother ATmega1284P in Wise Clock 4 would be trivial. How wrong I was. The first step was to burn the bootloader. After a bit of research, here is what I found out: USBtinyISP from adafruit cannot program chips with more than 64K of flash (see this thread ); if you don't want to start from scratch (that is, compile the source code and figuring the fuses) there are at least 3 sources: ryanmsutton , maniacbug and calunium ; USBtinyISP half-works: it writes to the flash, but reading back for verification purpose fails because of a bug in the firmware; I ignored the verification error; although burning the bootloader (any of the three mentioned above) seemed successful, uploading any sketch afterwards always failed; the setup from ryanmsutton did not work for me (I guess the fuses are wrong; then the core files also point to the arduino folder, instead of the sanguino, as it should be); with the bootloader from calunium (atme

Troubleshooting guide for Wise Clock 3/4

This should really be a chapter of the assembling instructions for Wise Clock 3/4 . Until I integrate everything into a single document, it is just another post that begged to be written (long ago, as a matter of fact). 1. Right after power up, the clock should make a beeping sound. If that does not happen, here are possible causes: missing input 5V power; the optional power LED may be useful in this case, turned on when the power is present; reset pin may be shorted to ground (the processor won't execute any code); processor may not be powered: check that pin 10 has 5V and pin 11 is connected to ground; faulty or missing the 16MHz clock for the processor; check crystal connections to the pins; if everything looks good electrically, try to upload a sketch; it that still doesn't work, test by replacing the processor or replacing the crystal; buzzer may be disconnected; check connections between processor's pins and buzzer, shorts to the ground, terminal soldering. 2. The di

Stand for ClockTHREE

Image
Some time ago I received, as a gift, this smart and very useful stand from fellow clock enthusiast Nicholas in San Diego. He designed it and made it specifically for ClockTHREE . Simple yet elegant, this is essential if you want your C3 on the desk or table. I did not have the chance to appreciate it until now, with an older  ClockTHREE  borrowed from a friend (I gave it to him as a gift). Here is the C3 on the stand, a perfect fit! Thank you Nicholas! Keep up the great work!

Wise Clock 4 - "Time Lived" menu option

Image
At the request of AlexT, I implemented a new feature in Wise Clock 4 , which allows the display of time lived (since birth) in different formats (years/months/days/hours/minutes/seconds, days only, hours only, minutes only). The above photo shows the year/month/day on the top row and the hours/minutes/seconds on the bottom row. Lifetime in Wise Clock 4 from florinc on Vimeo . The birth date and time are read from the file message.txt on the SD card. I was inclined to use the Time library, but I found it a little bulky for my needs and also unsuitable for dates before 1970. Then, I copied and modified the function makeTime() to convert a datetime to seconds, and I wrote my own diffTime() function to calculate the difference (in years, months, days etc) between two dates. Alternating between display modes is done by pressing the SET (middle) button. This code will be included in the next release of Wise Clock 4 software.

Wise Clock 4 Dual screen chronometer

Image
Update (June 30, 2014): This chronometer clock is complete now . It is also available in the two-sided (two-faced) version, aka "Kandinsky", as shown in these photos . This chronometer, inspired by the Doomsday clock by Wyolum , is made with a Wise Clock 4 board (available for sale here ) and two 3216 displays from Sure Electronics. Its main feature is the odometer-style rolling of the digits when they change. The time is updated once a second, based on the 1Hz interrupt signal from DS3231, as described here . As shown in the video, one button is used to change the display brightness, another button is used for changing the font, and the third is used for switching between rolling style and static style. By using the bigger (5mm) 3216 displays with the same setup and software, this clock can be easily read from a distance of at least 100 feet (30 meters). Source code is available here . The current version does not allow setting up the time and date from buttons.

Make a super hidden folder in windows

Today I will show you how to make a super hidden folder that cant be seen by anyone except one who have made. Normally, when you make any folder hidden by right clicking on it and setting its property to hidden, the it can be shown by clicking "show hidden files and folders" in the folder options. But, in my trick, after enabling "show hidden files and folders" also, you will not be able to see the folder. Read more »

Details on assembling ClockTHREE v2

Image
I just finished assembling another ClockTHREE v2 and I realized that there are details that need a bit of clarification (and not captured in the original building instructions ). These are related to the orientation of the RGB LEDs and the battery holder for RTC. Not a lot of info, but I felt I have to record these, since I will have to go through the exercise of figuring it out again next time I assemble another C3 . Here are the pictures worth a thousand words. First the LEDs, shown laying down in the correct orientation. The longest pin, the common node, is closer to the bottom of the PCB (where the ATmega328 is). Because the LED pins are only 0.05" apart (as opposed to 0.1" in a normal LED, or most other components for that matter), special attention must be paid when soldering these RGB LEDs. There is a tendency of shorting two adjacent pins, so make sure that doesn't happen, by checking with a magnifying glass (or with the ohmmeter). To avoid the possible shorts, I
