Update and a New Project

For those of you waiting for the oscilloscope tool, I'll be publishing an etchable pdf later this week along with the parts list. And for those of you who also watch my YouTube videos, I'll be doing a video on how to etch your own PCB. OK, onto the new project.

A few weeks ago, a friend of mine asked me if it were possible to create an emulator from an Arduino. So I explained to him, how an emulator actually worked, and the hurdles that would be necessary. All in all, not a very realistic project to attempt. Recently however I was thinking about the project again, and that it might be feasible. Thus, this is my new project, to try and build a DIY game console, from the Arduino.

Easy Oscilloscope Moving Along

So it turns out the design is a little more complicated than I had originally planned. I had to add a resistor to control the current on the low end of the potentiometer. I'm going to work with a max voltage of about 1 volt for the line in. I still have some testing to do but I should have a finished design, parts list, and etchable pdf by the end of next week.

In other news if you haven't check out this Kickstarter, or don't know what Kickstarter is, I'd check this out.

It's a game console for $100, based on Android, that is built around hacking.

Easy Oscilloscope

If you haven't already shopped around, you should know, oscilloscopes are pretty expensive. As an engineer , in school, I don't have a lot of money. However, I know a thing or two about electronics. I have portable computing devices that can run apps that also allow it to function as an oscilloscope; that's a $4 app to a $500 oscilloscope. The only problem is, it's more than a little difficult to mate whatever I'm testing with my tablet. That's where this little device comes in.
It's a regulator for the line in jack. It works off of 3 components, two diodes and a potentiometer, to set the voltage in. I'm almost done with the device, and I plan on publishing the ectchable pdf and parts list. If anyone knows what the max voltage for a line in device is please let me know, so that I can get the appropriate parts.
