This clock incorporates LEDs and mirrors behind a glass face. There were 20 or 30 different glass panes to choose from at the hobby store, but I chose this one because of its texture and unique light reflections. In this instructable, you might learn one or more of the following: how to drill a hole in glass, and how to build a simple LED circuit.
I live in a desert climate. It's very dry here. The adhesive methods I use for this clock may not work very well in a humid climate. I didn't have to worry about this so the construction here does not account for humidity.
I was inspired to make this unique variation of a clock because of the simple clock by instructables member Dipanker
My clock would have been just as simple, I think, if not for the idea to use glass, and then mirrors --- and I decided 12V DC would be safer for my kiddos than 220v :) props to him, though, for making me want to make a clock of my own.
As always, as I undertake a new challenge I am reminded that DIY from scratch is always a challenge, takes way longer than I initially anticipate, (seriously, my wife makes fun of me all the time because my 1 hour projects turn into 2 day ventures), is more fun to build, and if you have to buy every last item, DIY tends to cost more too ;) I had a lot of this stuff already, but here's a list otherwise: What you will need:First the electronics:
LED lights, 16 of them ($4 from ebay)
quartz clock mechanism (hobby store, $6)
12 V DC power supply (www.goldmine-elec.com 12v supply, $3)
330 ohm resistors, 8 of them (radioshack, $1-$3)
DC jack (radioshack, $3)
wiring (I used bell wire, $3 for 60+ feet of it)
PCB board (radioshack, $2)The hardware:
12 x 12 glass pane (hobby store, $5)
5/16" diamond-tipped drill bit (home improvement store had a kit with it, $10)
hardboard (home improvement store, $5)
wood trim, rectangle cube (home improvement store $8)
Duct tape (any desired color, $4)
mirrors (24 pack, $2)
Super Glue, I used E6000 ($3-5)
Blue paper ($1)
Glue stick ($1)
Handitack (?, I had this for years)Other supplies and tools needed (some optional):
Hot glue gun
tiny drill bits
plastic numbers ($3)
Estimated cost to build all this from scratch: $50 to $80
My cost to build it after deciding to build it (I own junk): $35
Hopefully this inspires you to make your own variation of a clock. Thanks for looking, I hope you learn something!
