Our friend Schuyler St. Leger added a vintage telephone bell to his Alpha Clock Five to make an alarm clock that could wake the dead— or at least a teenage boy who’s been watching late night TV.
This newly minted (date code: 1403) 555 footstool comes to us via Martin on Twitter, who writes:
My 555 footstools arrived. Build by my father-in-law, based on design files from @EMSL
Ann posted instructions in our forums for creating an electric kistka (wax pen) for the Eggbot for traditional Pysanky egg dying techniques. She used nichrome wire, krylon tape, a modified kistka, and a 2xAA battery holder with a switch and described how to mount it in the Eggbot. She posted a couple of designs to Thingiverse demonstrating the technique including the rose design pictured above.
For a Humpty Dumpty design, she wrote up how she made it:
Using eggbot and custom electric kistka, plotted the Humpty Dumpty picture and text on an egg. First plotted outline, dyed brick, colored in bricks by hand with kistka, dyed blue.
You can check out her other designs for the Eggbot on Thingiverse.
Dave wrote in to tell us about the kitchen timer he made:
I just wanted to say thank you for putting together such a great site and set of products. I’m a newbie and after about 4 months o studying your articles and using the Diavolino as my development board, was able to make a cool little kitchen timer for my parents this Christmas. I definitely could not have done it without your articles and products.
He documented the project with a series of videos (youtube playlist) showing his progression through building it. Shown above is the breadboarded prototype next to the finished timer.
Thanks for sharing your project photos and videos, Dave!
Over at EEVblog, the (simply wonderful!) Electronics Engineering Video blog, Dave Jones has posted episode #555 — about our “Three Fives” discrete 555 timer kit. It’s an hour-long video, in which he builds the kit on camera, and more importantly walks through the the equivalent schematic to explain (and show) how it works, right down to probing the circuit with a scope. If you’re interested in how analog electronic circuits work, you’ll likely find it to be an excellent use of an hour, even if you’ve already built the kit yourself.
Joyce sent us this picture of her 2013 Lord of the Rings Pez dispenser LED menorah.
I thought I’d share my new menorah hack with you all. Friends even started asking about “this year’s theme” so I guess it’s now an official tradition.
