  • I understand that the beginner is going to have limited knowledge and their tool bag is going to be low. But one of the most important tools to get is knowing how to search for an answer and why forums are so helpful. Just because you can throw a micro at a problem, doesn't mean you should.

    For my PWM applications where I need them to be cheap, versatile, and easy to use I recommend the TL494. What makes it so nice is you can use one pot to control the frequency, and another pot to control the duty cycle. They're readily available from digikey for $0.68. I used that IC for my plasma speaker and I was able to get a pretty large frequency range and 0-100% duty cycle, all I had to do was one calculation for my RC value to make sure I was within the frequency ballpark.

  • ~~Can't view the schematic, it keeps returning an Error 403.~~ Fixed now.

  • I came here to ask the same question. I even subscribed to his youtube channel hoping I would see an update, but no :(

  • That GPS wall clock needs some cable management. Those hanging wires make me feel like Louise Belcher

  • It's too bad you guys didn't use a reverse mount switch. Then you could add numbers on the silkscreen and get the board to fit in a hammond box or similar standard sized box. You could even sell it as an intro to SMD kit and have a nice piece of test gear.

  • The thing I like is you can have companies create hardware and software for the phone. On thing I heard about is being able to swap out your camera for a thermal camera. Given that FLIR has made a thermal imaging camera for iphone, the technology might be there to shrink it enough to fit in one of those slots.

    But what I find most amazing is the time line for the Ara phone. A lot of this technology used to make the Ara possible is being worked on as we speak, including the production 3D printer for the cases. They want to have all of that done by 2015.

  • I like the modesty at the end "or even bleed into tomorrow"...I think we all know it won't bleed in to tomorrow.

  • Can you connect an LCD to it to display the song info?

  • From an electronics standpoint, what a useless article. But from a long time customer standpoint, what an amazing article to read. This is why I can never see myself not as a Sparkfun customer, the closeness you make me feel as a member of the Sparkfun family member and the transparency from a company is so refreshing and makes me glued to the jobs page, hoping to see an opening for another electrical engineer.

  • As a member from one of the schools that was there, Sparkfun has absolutely played a large role in developing our nanosatellite.

No public wish lists :(
