Wirelessly controlled flaming Halloween pumpkin uses an Arduino

Halloween is a great time for makers, we get to make all kinds of cool costumes and spooky things.  Sometimes we get to play with fire.  Well at least Chris Lee does.  This flaming pumpkin is enough to keep them pesky kids from toilet-papering your house, or catching it on fire after they do.

The pumpkin is triggered by an Android phone, talking to a RFU-328 radio and Arduino.  The Arduino triggers 2 relays, 1 to activate a furnace igniter, the other activates a solenoid that releases the flow of gas.   The spray mechanism comes from an AirWick room spray and is filled with butane.

Chris made a comment about maybe converting this to shoot silly string out during actual Halloween, either way it’s a cool project.

How to remove an IC from a PCB the unusual way

It’s Friday… and you are probably are stuck at work.  So why not learn how to remove a IC from a PCB — in a very very unconventional way.  It’s great if you don’t care about the chip… or the board for that matter.

Seriously though, if you need to relieve some stress, the guys who made this video Electronics In a Nutshell have a very entertaining channel on YouTube where they mostly torture circuit boards and stuff in various ways.  Just the way we like it.

Here’s another entertaining video to get you through the day.  Lithium-Ion battery vs 220 volts.

The BFG3X is a boss killer

bfg2Any fan of the DOOM series of video games remembers the BFG‘s or Big Fucking Gun.  You know you wanted one, and so did Andrew.  The only difference is Andrew decided to build one, and I’m guessing you didn’t.

From the beginning of Andrew’s build, it looks like your normal prop build.  Start with a trip to home depot, grab some pvc pipes, solder a few leds, spray paint the whole thing, yadda yadda.  But then you see towards the end of the video that Andrew put some beefy wires and a grill igniter inside… oh yeah…  It’s actually a 3 chamber potato gun!  And sure, you put enough fuel in it and it will do some flame thrower tricks as well.

The lighting effects by themselves look pretty good, the flash light mod, and the home-made acrylic light tubes… I bet this would keep those damn kids off my lawn!

Be sure to watch the video after the break.
