I want sparks & I want them NOW!
Update May 2003 - Marx Three is now up & running Do you like the idea of tesla coils and other high-voltage sparking stuff, but don't have the time, money or patience to build something that elaborate? Here's a fun little project that can make big, fat, noisy sparks at least 2 inches long, and can be built very quickly and cheaply. The Marx generator consists of an array of resistors, capacitors and spark gaps arranged as follows: The capacitors, C, are charged up in parallel via the 1M (one megohm) resistors, so they each become charged to the input voltage. Rb has a ballasting effect. Although it is possible to make a Marx generator with just an array of resistors, capacitors and spark gaps, it can be hard to make it fire reliably, as it will depend on the breakdown voltage of the spark gaps, and there can be a fine line between not firing and firing before all the capacitors are fully charged. Component choice An input voltage of about 4-8KV is recommended. Power supply "Marx Two"

At first glance I thought this creation was some sort of wooden gear clock. If you go to the project site (click on the image) you will find an array of chutes and barrels and other things for the balls to do on their way down.

you knew i was going to make one. they are all over pinterest....(i still am not signed up for pinterest because i don't have time for one more thing but browsing is fun!) so we made one. i took a box of 64 crayons and took out the blacks and browns.i used another small box and doubled up on the good colors i liked and hot glued them to the top of our canvas. then we turned our blow dryer to hot on high. not long after you set the hair dryer by the crayons they get shiny and then the wax starts to melt! and it dries really quickly too. seriously. what could be happier than this?? GREAT project. loved it today is the first FULL day with ALL my kids in ALL day school.yeah...i am smiling as i type that. it's good. it's quiet. i am rockin' it. removing wallpaper.....making code for craft weekend stuff.....doing my hair....going to lunch..... it's all good. hooray for school!
