I finally finished upgrading my clock to to the xmas firmware with a 328p and a gps module.
The only module I could find at that time when I was looking was the adafruit flora gps module but it works just fine. The wires could have been trimmed to eb shorter but I think it adds character and since it fits I don't care enough to mess with it further unless needed.

Finished my clock.

Followed the guide, did the stage checks - got worried towards the end as the tube did not appear to light; carried on assembling the case and tried powering the clock when it got a bit darker, and it worked! Currently powered off a 9v battery, as I have not got a suitable adapter (or a USA to EU adapter) until I go to the shops :)

The hardware for this clock was mostly from Adafruit.

Finally had time to assemble the Ice Tube Clock kit I purchased recently.
I took my time, made sure all parts were correctly installed and made sure to do a good job soldering and each test during board assembly passed.

Here are a few tips for those new to building the clock that might help out:

The clock when first built and turned on has the brightness defaulted (set) to the dimmest setting making it very hard to see to set in normal room brightness.
The Brightness setting is the 4th menu in. Press the Menu button 4 times, then press the + button 3 or 4 times to raise the brightness to 50 or 60, then press the set button to save the setting before trying to set other options. This makes it easier to read the clock while initially setting and getting used to how the tube displays the menu options. The brightness can adjusted again later as desired.

The Ice Cube Clock blinks the display after a power loss. This is normal, Go to the "Set Time" option to stop the blinking.
- This how it's supposed to work.

If the clock does not keep time while on battery. The FET Q3 is likely to be installed backwards, take it out and turn it around.
I have found that the current FETs in the kit match the silkscreen (rounded side of FET with writing on it to rounded side of silkscreen) when installed properly. This is contrary to the assembly instructions

Make sure to get all of the buttons and the switch flat to the circuit board and keep them flat before soldering them in place.
They won't fit through the case holes if they are not flat, so pay attention to that detail.

Now off to make some mods :)

Just got around to building the Monochron that I bought last month! :) It's very nice, but I still like my Ice Tube Clock more. Next step is to put together the case.

Flashed the Multichron 1.1 firmware on it using an FTDI cable. At first I forgot to plug in power and I was wondering why avrdude kept failing to work. :oops: It should probably be noted in the docs that the FTDI connection cannot be used to power the AVR!

An Ice Cube clock that I'm embarrassed to admit I started way back in 2009 and just got around to building...

Hi Mulveyr, nice clock!

It looks like you might have an old kit which included a 2907 BJT transistor for Q3, while newer kits include a FET. The problem with the 2907 was that without a resistor on the base, Q3 sources too much current from the microcontroller, which can eventually cause microcontroller to fail. See this thread for details.

An alternative to requesting a FET as a replacement from Adafruit if you have a transistor for Q3, is that you can use parts from Radio Shack as Russel 27 explained how to do. If you have a store nearby you can get a resistor to modify the existing transistor with or just get a new transistor and the resistor to make the mod.

Ah! Thanks guys! I have a Radio Shack down the street so I can get the parts very easily. I appreciate the heads-up.

Just finished my Ice Clock kit this afternoon. Great build and directions. I especially like that there were multimeter checks along the way, and very detailed and clear photos. I'd recommend this kit to anyone... It's one of the nicest clocks I've seen.

The Old and The New

by Avian on Sun Feb 16, 2014 11:28 pm

I'm posting a picture of the old and the new. The old is the Heathkit GC-1092A clock that I built when I was home from college in the summer of 1977. This clock has run continuously since I built it, aside from the occasional move or power failure, of course. Just as a point of comparison, I dug out the assembly instructions and counted up some of the parts that went into the clock: 102 resistors, 15 capacitors, 31 diodes, and 34 transistors. And that's not counting all the other bits of hardware like a transformer, speaker, displays, switches, and so forth. As I recall, it took me several weeks to put it together. The assembly manual ran 60 pages, including schematics, diagrams, and theory.

It had a couple of the features of the Ice Tube clock - battery backup and a photocell to adjust brightness based on the ambient light. I've added John Archie's updated firmware to my Ice Tube clock, which automatically adjusts the timekeeping as you reset the time. The Heathkit clock had an adjustment where you tweaked it until it matched the 60-cycle AC cycle, allowing for very accurate timekeeping.

The Ice Tube clock was a fun kit to build. I remember opening the box and thinking "Okay, now where are the rest of the parts?!" I'm working on making a base for the clock to keep it from sliding around. It's a light clock - nothing like the heft of the Heathkit! The base is sort of a work-in-process. What you see is a piece of scrap wood with four notches cut out for the four corners to sit down in and a piece of non-slip rubber material on the bottom.

I'm looking forward to using it - hopefully, I'll get 37 years use out of it as well!

Cheers,

Bob

The Marvinchron

by TerranJerry on Tue Mar 04, 2014 10:24 pm

This is my Monochron Clock. I received it for Xmas. Thanks Adafruit for a fantastic design and super fun project! My clock was a pretty standard build though I chose to solder the FTDI header into my board for a more reliable connection when programming. The secret to doing this is assembling the case from the back to the front rather than front to back. It wasn't hard and it allowed me leave the header permanently attached.

I took the code to Mariochron (credits and big thanks go to techninja (James T) & Super-Awesome Sylvia) and I modified it to come up with my own "Marvinchron".
Since Marvin Martian is one of my favorite cartoon characters, I dedicated this version to him.

The screen shows Marvin marching back and forth at the bottom of the screen (thanks Mario) and on the minute, he zaps the small spaceship at the middle of the screen.
Of course a new small spaceship flies right back into the scene after Marvin zaps it. He leaves this new spaceship alone until the next minute.
On the 5-minute intervals, a much bigger spaceship enters the screen from the right and uses a laser to zap the small ship.
It then takes up residence in the middle of the screen where the smaller ship was originally.
Marvin studies it for a moment and then... yes, you guessed it.... Zap! Marvin takes out the big ship!

Anyway, I hope you enjoy these photos of the "Marvinchron". My kids motivated me to do this because they like Marvin too (and especially appreciate how much I like him!).
Kind regards,
Jerry

Just finished! Great kit! And solving the little problem I had with Q3 actually added to the fun. How boring if it had just turned on and worked the first time.

I don't smoke but a buddy that does gave me these old wooden Don Tomas boxes. Perfect for the Trinket Clock driving Analogue Panel Meters...
