Is a video a MUST for this competion?

Unfortunately I'm one of the persons who doesn't possess a video camera, and the one built in my cell phone isn't worth thinking about.

I could of course post a sequence of photos if this OK.

I would love to see what you come up with. The rules say video but I will not stop you from entering a project with a sequence of still. The general membership will vote based on what they see...

FWIW most still cameras will take a few seconds of decent quality video.


I also will have a surprise for a Christmas gift contained in my project. (shipped free!)

I am clueless about this one. You are shipping a Christmas gift contained in your projec to who ?
 
Hi 3v0,

I'll try my best to get a usable video from a still picture camera.

My project contains a riddle to solve. (project in project)

I don't want to make it too difficult and will offer a multiple choice answer. There will a selection of at least six answers with only one true.

The rule(s) is (are) simple: the one solving the riddle first (according to reply date and time) will receive a typical Thai artwork sample. (no electronics involved).

One hint for everybody who will try to solve the riddle: get a bit familiar with star pictures - not the Big Dipper or Cassiopeia. They are too easy.

Regards

Hans
 
This came via PM.

Oh man, what a great contest.
Hello 3v0,

Great idea, this is what got me interested back into electronics...

It is ....XXXX.....
(Lets see how long it takes the next person to figure it out)

Very nice concept and execution.

EDIT:
I assume this is a uC entry. Can you give us a image of it so we can see the hardware.

Easy enough, just copy your answer.

This is a non uC-entry. Schematic and pictures to follow.

My circuit has worked fault-free for over ten years, originally built on two PCBs for easier servicing. A comparable single-board design is possible if you choose. The PCB is designed around the optos and heatsinked triacs if more than 25 bulbs are used for each pulsed input. Fuses assure overload protection.
The small size makes it possible to conceal the circuit inside the attic behind the eavestroughing. An extension cord and switched timer can be added to the existing circuit, if no outlets are included in that home wiring circuit. Power line noise does not affect this circuit, especially furnace motor spikes.
 
So far we only have two entries in the MHLDC. At this point both are set to win $125 in PCB manufacturing credits from Sunstone!

musthave - in the microcontroller catagory
Boncuk - non microcontroller catagory

Only entries posted to the entries thread will be included in the voting if you posted one in another thread repost it to the entries thread.

You can enter up to the time I post the voting thread on the 11th of January.

My video is on VHS tape, which I gotta find and upload it to this post. It cannot be done in time for this contest. Being in a remote location away from the workbench is not good.

Upload it anyway if you can make it happen. It would be fun to see it if possible.
