Jeri Ellsworth shows Trimet how to save $4590 with their new bus audible turn warning system. I need to credit @pdxcommute @oregonian for some of this information and probably a dozen other bloggers. Thanks to Trish for bringing this to my attention and Bobcat for the concept of The Oregon Trail This sexist comment was left by the Technology Officer of Protran1 in response to this video - "I hate to tell you this but; you have set back the progress of women 100 years. The system developed for Tri-Met was developed by a woman after careful research and development. Also, it has been deployed at several transit agencies prior to Tri-Met and the statistics speak for themselves. Your opinions are without facts. With your logic we should get rid of CO2 and fire detectors.

MORE INFO: hey.com We asked Jeri Ellsworth about the 555 Contest which she's organized with Chris Gammell, where 238 entrants have submitted projects that make use of one or many 555 timers, the 8-pin integrated circuits used by the billions in devices and machines worldwide. The contest is now in the second round, and finalists have been named in Complex, Minimalist, Artistic, and Utility categories. Jeri was last on our show on Nov. 24 when she talked about the homemade Organic Light Emitting Diode (OLED) she built. Find out more about the 555 Contest at 555Contest.com and Jeri on YouTube and @jeriellsworth on Twitter. Host: Dane Golden twitter.com | hey.com

HEAR THE COMPLETE PODCAST: hey.com Jeri Ellsworth is a self-taught chip designer, pinball wizard and former race car driver/designer and roller derby queen. She built a retro Commodore 64 joystick that was a popular toy, and she taught herself how to make a microchip in her kitchen. And now comes her most recent project - a homemade Organic Light Emitting Diode (OLED). We talk to her in her nerd lab to find out how she did it, and a few other facts.

Support the show! tymkrs.com You can talk to us daily at our IRC chat (#tymkrs on AfterNet): qwebirc.afternet.org zombietech.tv One of our favorite subscribers, regular commenter, and fellow DIY broadcaster, Jeri Ellsworth, on TWiT.tv with Leo Laport and Tom Merrit on January the 12th 2011. This was one of the most enjoyable twit live shows ever. Another one of our favorite subscribers, Darren Kitchen from www.HAK5.org (and regular twit contributor), was in the live chat, and we got to say hello to him too! Awesome fun. He suggested a show with Jeri and him on Twit - if that ever happens, we totally want to contribute! Such a thing would cause the technolust cup to overfloweth. For more Jeri, check out her channel: www.youtube.com And yes Jeri, that's your head 6 feet tall - as if Leo wasn't giving you a big enough head as it is! Hah.

This is a project I pushed to get manufactured in 2005, but was canceled due to the cost of flash, "lack of fan base" and the declining plug and play toy market. The games for the Amiga were usually a single floppy disk or more and would take up too much space in flash. It was difficult to convince the toy manufacturer it was worth paying for more than 2megs of storage. The manufacuter also worried that the name Amiga was not as recognizable as Commodore C64. The year the c64 joystick came out the market was flooded with really bad plug and play games like "Spider Man" and "Sponge Bob", which pretty much wiped out interest in this type of toy.

Jeri Ellsworth describes how she attached a floppy drive to a tape deck recorded and then played back audio. A simple circuit stepped the head automatically using the spindle index pulse. A push button was used to control the direction. The drive head wrote to more than one track at a time, causing an interesting reverb effect. ***Erasing the disk with rare earth magnets while spinning in the drive was not mentioned in the video.
