Given that we are self-proclaimed geeks & gear-heads, doing a booth about gears seemed only natural.
I've previously posted about our adventures building a 3-speed Lego NXT robot-based transmission with clutch, building a mini mobile billboard, and laser-cutting some souvenir gears- now for some pics of the big day...
|Get out a camera, and watch what happens...this is the view from the backside of our view. Candy is playing treasurer for all the fundraising cards & my older son and our Pack's Committee Chair are hanging a banner...|
|He's crossed over into the Troop, but he was HUGE help to the Pack (and ME!) at the Scout Show|
|Big dude showing off the transmission...|
|Little dude showing off the transmission...|
|Big dude has a future in sales...|
|Big dude answering questions...|
|My younger son doing his part to demonstrate the different kinds of gears...he even noticed that one of the gears was a combination helical and spur. He was so proud when he ran over to tell me!|
|The transmission ran CONSTANTLY that day. I finally gave up on the rechargeable batteries and wired it to my bench power supply that I'd grabbed on the way out the door.|
|This bent binder clip saved the day when I decided to ditch the batteries and run the NXT transmission off the power supply. I _should_ have pre-built this, but luckily I made it work at the show. Thanks to Paul for having a binder clip!|
