Weekly Roundup 10/1/11

In case you missed them, here are our most popular posts from the past week.

Our most popular post was about a Chinese man who is attempting to build an octocopter that he can fly around by pairing motorcycle engines to propellers. There were a considerable number of comments on this one!

Next we have a post about a project where a 12-series PIC is used with a single inductor to create a working RFID tag.

Our third most popular post was [Bertho’s] tutorial about capacitive sensing. This is his entry into the Dangerous Prototypes 7400 Logic competition so you’ll really get to see the nuts and bolts of how this type of sensing works.

Next is a post that is about a pretty unique lathe made out of concrete. If you have the weight capacity in your workspace, this could be a nice addition to your tools.

In fifth place is a post about [Eric’s] second revision of his word clock that tells time in German!

In case you missed them the first time, here are our most popular posts from this past week.

Our most popular post was about a ‘flashlight’ build. We are using the word flashlight loosely since this monster can draw up to 500 Watts!

Our next most popular post was about another [Jörg Sprave] project where he has built a very large slingshot that can shoot shot puts. He then proceeds to destroy a car with it.

This post describes an open-source Segway. It is built around an ATmega644 has a nice professional look to it.

If you live out in the country and have a problem with rats, this post could be for you. In this post, we look at [Snypercat’s] build where she has mounted a camcorder onto the scope for her pellet gun and also attached an infrared light source so that she can snipe rats at night.

Finally, we have a post about a custom V-12 Kawaskai Voyager. If you are looking for a great way to draw attention at your next motorcycle rally, this post might give you some inspiration.

In case you missed them, here are our biggest posts from the past week.

For the weapons enthusiasts in our audience, make sure to check out our most popular post this week where [Liquider] shows a project in which an airsoft pistol was converted into a coil gun.

Our next most popular post was based around an xkcd comic where the concept of viewing clouds in 3D is explored using a pair of webcams. This post had lots of comments and also spawned a forum topic.

Next up is a post about a reward that has been place on the head of porting Android to run on a HP Touchpad. The bounty for all of the various challenges was originally $1500 but now sits at $2275!

This isn’t our normal fare since we usually don’t cover hacking that could be malicious. This post describes some of the exploits covered recently at Black Hat and Defcon.

Finishing up the pack is our own video where [Jack] shows how to build a stun glove and proves that it works by taking a jolt from it himself.

Hackaday Weekly Roundup

In case you missed them, here are our most popular posts from this week:

First up is [Bertho’s] Pointless Switch machine. This machine is yet another take on the ‘most pointless machine’. It looks like his server couldn’t handle the load from his video so he moved it over to youtube. You can find it here.

Next is The DIY nuclear reactor, which links to a project by a fellow who was silly enough to post his nuclear experiments online. You can imagine how that went…

This week’s most popular post was the tutorial created by our writer [Brian Benchoff]. In this tutorial, he shows how you can insert your logo into a still-readable QR code.

After that is this post showing how you can resurrect your IBM model M keyboard to use it as a bluetooth device.

Finally, we wrap up our roundup with a brainwave disruptor. This device allows [Rich] to experiment with light and sound to see how it affects brain waves.
