New to the Hackaday Store today is the Bulbdial Clock by Evil Mad Scientist Laboratories. I’ve had my eye on this kit for years and finally pulled the trigger after visiting [Lenore] and [Windell] at their shop a few weeks back. Assembling the beautifully-engineered kit was a delight, and I have a handful of hacks I’d like to try out — some of which I mentioned in the product description.
Free shipping based on order price
We always listen to what the Hackaday community has to say. After receiving several requests for better international shipping prices we came up with a way to ease the pain for orders no matter where they are headed. All domestic orders totaling $25 or more now receive free shipping. All international orders totaling $50 or more now receive free shipping.
Is there anything else you’d like to see different about the store? How about a hackable product you think we should stock? We’re listening via the store contact form.
I’ve been a huge fan of EMSL for quite some time now, and my recent field trip proved that it has earned the name Evil Mad Scientist Laboratories for a good reason. For instance, look at the reflection in the glass near the bottom and you’ll glimpse the hearse that [Lenore] and [Windell] have sitting in front of the shop. But stop at the threshold, inside there are delights that ate up a couple of hours without me even noticing. And they thought they were going to get work done that day.
Don’t judge me by my appearance. This is late afternoon on a summer Saturday in Sunnyvale. Why does that matter? Obviously summer Saturdays in Silicon Valley always start with the Electronics Swap Meet and Engineer’s breakfast! That was a ton of fun but if you’re doing it right it’s also a bit tiring. No worries, a shot of excitement came over me as soon as I walked in that front door.

We never thought about it before, but having the controls on the bottom of a clock is a bit of an inconvenience. [Alex Whittemore] mutes the LEDs on his clock each night and after a while, decided he should make the mute button into a touch strip on the case. You’ll remember that the Bulbdial clock uses colored LEDs to create the effect of a sun-dial, casting colored shadows for each hand of the clock. It makes sense that this would put off a pretty good amount of light at night. [Alex's] original thought was to use a capacitive touch sensor but complexity and cost were in his way. What he ended up with is a resistive touch switch based off of two metal strips. He used metal repair tape but suggests copper foil as he was unable to solder to tape. When your finger touches the two strips it completes the circuit for the base of a transistor, which in turn grounds the mute button on the clock. Cheap, simple, and illustrated in the video after the break.

[Taufeeq] sent in his “Circle of Light” bulbdial clock. You may remember when we showed you Evil Mad Scientist’s version a while back, and [Taufeeq] did use it as a base but he’s added some of his own little touches. Some of the changes include using a PIC with an RTC chip instead of AVR, which allowed him to shrink the board down small enough to fit behind the clock face, rather than on front. He’s even zipped everything up conveniently to help you build your own.
Evil Mad Scientist Laboratories has built the bulbdial clock, an idea originated by Ironic Sans. It’s basically a high definition indoor sundial. The LEDs arranged in a circle shine a light on the peg in the middle casting a shadow, just like a sundial. There are 3 colors of rings, allowing for hour, minute, and second shadows. This isn’t the first time that Ironic Sans has seen ideas come to reality. There were the pre pixelated reality show clothes and the sneaky histogram hidden message system. While it is a cute idea, it isn’t really new. People have been patenting this idea for a while.
