One Square Inch of Goodness

So a while ago I discovered that I needed a microcontroller in a really tight space. I tried an ATmega328P PU (DIP package), but try as I may, It would not fit. The answer? The ATmega328P AU (TQFP) this is a much smaller package, and for an added bonus, it has 2 extra ADC’s. This a great little board to squeeze in various projects, and opens the door to some very cool stuff I have coming up. Some of you might remember I put this board in a project I did a while ago when space was very limited. It’s just a handy little board to have on hand. 🙂

In the video above, I show some soldering with TQFP packages, as well as a little soldering with hot air. I need to figure out a way to record video from my brain. It would make things so much easier..

Oh, I almost forgot, the flux pen I used, found at Sparkfun.

The Eagle files for this board are on my Github page. Or just the schematic PDF.

SMD Soldering – You can do it!

Here is a video on SMD (Surface Mount Device) soldering. In this video I show how to solder some SMD components on to a little board with an ATtiny85V, switch, LED, and resistor. The short version of this video just shows the resistor and LED (size 603) being soldered, the long version of this video shows everything being soldered. It’s really neat to open up the world of SMD. You can make really tiny (and cheap!) widgets! Continue reading →
