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.
Here’s a little project that we’ve been working towards for a long time: a custom-painted leather flight jacket (“bomber jacket”) featuring the “Classic Lego Space” logo. (Yes, I totally spent years serving in the Lego space corps!) And, if you’ve ever wanted to make your own painted leather jacket — whatever the theme — here’s how to do it.
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!
Ryan Lane posted a couple of short videos of the WaterColorBot drawing a Storm Trooper and Seattle with markers. He traced a photo of the Storm Trooper and applied a half-tone filter before plotting with the WaterColorBot.
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.
