Fresh hacks every day
Here's an interesting interview with [Jeri Ellsworth] over at the Jenessee Network. Usually the interviews I see popup with people are fairly short and sweet but this one really delves into many subjects and takes its time to explore. They start off talking about how [Jeri] began with hacking, which was literally smashing toys "with rocks" to see what was inside. They move on to discuss her … [Read more...]
[Jeri Ellsworth] finally set aside some time to talk about the build process for her Commodore 64 bass keytar. We think what started by taking a band saw to the guitar body ended up as a fantastic new instrument. When she was showing off the project at Maker Faire we really only got a cursory look at what it could do. Her most recent video covers all that went into pulling off the project. Once … [Read more...]
Several bright young engineers have been swiped up to work for Valve. Yes, that Valve, the game company. Amongst them are [Jeff Keyser] aka [Mighty ohm] and [Jeri Ellsworth], both names that we have seen on these pages many times. We've heard that Valve is a fun and very unique company to work for. Apparently there's no solid hierarchy. What we, and everyone else in the universe wants to know … [Read more...]
[Jeri Ellsworth] had a bright idea - a brain-activated light bulb that floats above your head. While out and about, she saw some guy with a video game icon attached to metal rod sticking out of his backpack. The rod made the icon appear to be floating above his head (think The Sims), which was the inspiration for this LED powered light bulb. The bulb is connected to a metal rod, as well as a metal … [Read more...]
In her new element-14 video [Jeri Ellsworth] explains some concepts about “free to you” energy and features the LTC3109EUF, an Auto-polarity, Ultra low Voltage Step-Up Converter and Power Manager, along with the LTC3588EMSE a Piezoelectric Energy Harvesting Power Supply. Using the LTC3109EUF she is able to power a modified Nintendo Entertainment System, and LCD using a small generator … [Read more...]
Remember how fun it was studying chemistry and physics in high school? Well we guess your recollection depends on the person who taught the class. Why not have another go at it by learning the A-to-Z of electronics from one of our favorite teachers, [Jeri Ellsworth]. You know, the person who whips up chemistry experiments and makes her own semiconductors? The first link in this post will send … [Read more...]
[Jeri Ellsworth] has put together a couple of videos that cover how she made her own organic light emitting diodes, or OLEDs. In the first video, after the break, it discusses the difference between regular, rigid semiconductor LEDs and organic LEDs. The video then goes on to show how to make an OLED as successive layers of materials. Indium tin oxide (ITO) on glass forms a transparent anode. That … [Read more...]
