Here we have a dice LED clock kit. Yes, it's true. This time, it comes with a board. And it's discounted! Why? Well, there was a time (less than a year ago as of this writing) when there were no boards designed for any of the clocks (mostly because there was no feasible way to get them manufactured for remotely reasonable prices) and there was an open offer for sharing the source code with someone who designed one and physically provided boards. Well, he didn't do a good job. It has errors. Fortunately, they have been found and a short procedural series of corrections makes it all work the way it should. That list is included with the kit. A few connections need to be thrown in - connect a wire between two nearby soldered points - leave out a component here or there, connect it between 2 different points instead. And frankly the board is uglier and needlessly bulkier than the one done right (if you want something done right, you've got to do it yourself) which can be bought here (click here). Also, he made the spacing too big for my little speakers. The speaker you see in the picture is not exactly the same kind it will come with. The one it comes with is a little smaller. Either way, it doesn't fit nicely into the board with wire leads that come as part of the speaker. You'll have to improvise something. Fortunately, you'll have a LOT of little wire snippets - because ALL those LEDs come with long leads, and you'll be cutting a lot of them. Solder 2 to the 2 contacts on the speaker and then solder those into the board. It is the same kind of clock as the other dice clock. 1 left as of now. Once I've gotten rid of it, that's it, it's the full price board or none at all.
It counts the time and stores 15 independent alarms that can all be set to different times, yet has no calendar function, so they all go off every day (if they are enabled). What was I thinking? I don't know. But that's the way it is. It is the same type of clock which is shown here, it's just that this time it comes with an actual board! What a time-saver!
Other clock kits with boards (more expensive):
Circular ring (3.9 inch board) (click here)
Zig-zag ring (3.9 inch board) (click here)
Infinity (1.95 x 3.9 inch board) (click here)
Tiny 5 cm square ring (1.95 inch board) (click here)
Dice clock PROPERLY designed (1.95 x 3.9 inch board) (click here)
Other clock kits without boards (less expensive, but in some ways better because the board is less personal and rather small):
The dial-type LED clock (click here)
The same type of clock (dice clock) as this but without the green board (click here)
The board you see in the darkness there is a green rectangle which is 3.9 inches on one side and 1.95 inches on the other. Click on the picture to see it big, and use the left and right arrow keys to move around. This is the only photo taken in the dark, so if you want to see the particular color of green you can expect the board to be, look at the listings for the other (more expensive) clock kits with boards included.
First of all, I want to make 3 things clear.
1. You are not buying the clock in the picture. That one is my demonstration piece. It took me too long to solder together for me to throw around that with a 20 or even 30 dollar pricetag. That would be half minimum wage or less. It took long enough just to get the components together to make the kit.
2. You are buying a kit. You get 50 LEDs (one spare), a programmed microcontroller, resistors, capacitors, a crystal, a speaker, etcetera, a circuit board, and an information sheet on specifics you'll need to get it right. This does NOT include a power supply. You need to give it 6.3 to 12 volts DC from somewhere. You also need a soldering iron and solder.
3. The kit does not contain ultra-bright brightly colored LEDs as seen in the picture. I realize this is misleading. Especially considering the nature of the picture, shining there in the darkness. Though of course I could strictly speaking make it look like that no matter how dim the LEDs are, by adjusting the photo exposure time, so it's not really that dishonest after all. But you don't want them anyway, the LEDs are actually too big, I had to cut the edges off with a knife and I cut myself up the wazoo to get them to fit and make that demonstration piece anyway. You get generic red and green LEDs. Just like the LEDs that come standard with the other kits (to see those LEDs really up close, look at the tiny 5 mm clock - those LEDs). Those pink and green tinted LEDs that come standard with this kit are also sold on their own on the website here.
A demonstration of this clock can be seen here (make sure to be patient when downloading this, and try to RIGHT CLICK on this link and tell it to save rather than left click to just open, though I don't know if that's still the way it works, it just is as of this writing, and make sure to have some kind of pop-up ad killer in place: mediafire will definitely zap you if you don't):
