Weekly Roundup 2/4/12

Another week has come and gone and that means that it is time for our week in review. These are the top posts that have been viewed at Hackaday in the past week.

Coming in at first place is a post about a project by [Red Jones] and [Brian Kast] of Sandia labs. Ethical issues aside, this is a pretty cool project. They have developed a bullet that can be shot out of a smooth-bore gun that can hit within eight inches of a target one kilometer away. That is pretty amazing. It does this magic with an 8-bit processor. This takes the microcontroller wars to a whole new level. Are they using Microchip, Atmel or (gasp) something else?

In second place is a follow up post to our post asking how to control three LEDs with three switches, all in series. That post, although it was posted in December 2011 came in at number three. Getting back on topic though, this week’s post shows how he did it! Not only that, but it shows the extent that he went to when making it. There is footage through the eyepiece of a microscope showing him building one!

Want to use LiPo batteries in your next project but are afraid to use them? Here is a post where [Paul] shows off a circuit that he built that can charge LiPo batteries using a MCP7813 chip from Microchip.

Finally, rounding out the five is a post about a blog that was taken down but luckily not before the IEEE made a copy of it. This blog was made by a robot operator working at the Fukushima nuclear plant and detailed their ongoing cleanup operations there.
