Arduino-driven clock that writes the time, erases and repeats
Self-declared “Geek Mom” Debra posts some pretty amazing DIY projects on her blog, and this version she made of the PlotClock is well worth a closer look.
As you can see in the video above, the PlotClock is a timekeeping device that diligently wipes away the previous figures before scrawling the current time with an erasable pen.
“There is something very human and endearing about the motion of the arms as they perform their task of drawing and erasing over and over and over again.”
Debra followed instructions that she found on Thingiverse and incorporated extra modifications suggested by other Thingiverse members. Even still, resolving the design was an iterative process that included using SketchUp to visualise how the mechanism works before sending files to Ponoko for laser cutting.
“The upload and ordering process was very easy. The hardest part was waiting for the package to arrive.”
And arrive it did, in a timely manner. Read on to discover how she added in a variation of the 3D printed cap for the dry-erase pen, and used the flexibility of Arduino programming to customize the code to the specific requirements of this project.
Turning your house plants into autonomous cyborgs
For many people, keeping indoor plants happy is a task they just can’t get their heads around. The mysterious fine line between care and over-indulgence; occasional attention and neglect… the simple truth is that we don’t all have a green thumb.
With this laser cut arduino-driven project from Instructables user 10DotMatrix, some of the guess work is taken care of. An array of solar panels mounted on 3D printed brackets track the direction and strength of the sun, and then navigate the unit into the optimal position for maximum sun exposure.
Combine this with the clever Plant Friends moisture sensor and you could be well on the way to creating an arboreal cyborg.
A lot of thought has gone in to how to achieve this, so if your indoor plants could do with a techno-makeover, check out the project page over at Instructables.

Ponoko laser cut Kickstarter trains you to fall asleep. Eyes closed, now breathe…
Chasing those Z’s is about to get a whole lot easier thanks to this nifty innovation from Jeremy Wilson on Kickstarter. The Sleep Sensei sits on your nightstand and gently guides you towards a deep, restful sleep.
How does it do this? To some insomniacs, such an achievement may sound like pure magic, but there is some serious science behind the device. Jeremy’s own insomnia saw him trial numerous sleep aids before he set out to use his Arduino skills to sort out their collective shortcomings.
The functional laser cut prototype pictured above is at the core of this Kickstarter campaign, with the final design yet to be revealed. The key technology has all been sorted out already, as can be attested by an overwhelmingly positive outcome from product trials on real sleep-challenged volunteers.
“The Sleep Sensei primarily helps those with sleeping problems caused by stress or an overactive mind at bedtime.”
If you are one of those creative over-achievers who just can’t stop their mind racing at the end of the day (we probably all know at least a few people who fall into that category!) then head over to Kickstarter to discover more about The Sleep Sensei.
Anatomy of a successful Kickstarter
Jeremy Williams is the San Francisco based engineer / hacker / programmer / maker / video game enthusiast behind the Game Frame, a fully-programmable grid of LEDs designed to make it easy to display animated pixel art and old-school video game graphics.
Earlier this year Jeremy raised over $154,000 on Kickstarter for the Game Frame – an amazing sum considering the project’s original $15,000 goal.
7 months later – With the last of the Kickstarter rewards fulfilled, we sat down with Jeremy to get some insight into what led to his amazingly successful campaign.
Here’s a look at what has happened before and after the campaign was funded, along with some important lessons—both good and bad—that crowdfunding hopefuls can learn from Jeremy’s success story.
