While I was at Maker Faire this year, I was booth-neighbors with the great Fredini who was 3d scanning folks the whole weekend. I was one of the luck folks to be scanned!

Big Fat Sale at Rocket Brand Studios

 

Come one, come all. Rocket Brand Studios is having our very first sale of all time!

RBS is sitting on a fair amount of inventory right now and it would be nice to see if we can turn some of these robots into a bit more working cash for our up-coming trip to Maker Faire 2013 NYC. This all simply translates into savings for you!

Ting!

Prep for Maker Faire 2013 NYC

Howdy Y'all,

We are starting to get close to Maker Faire this year and I suppose it is time to start getting some ducks in a row.

I am planning on attending Education Day as well as the Fair itself, representing both Let's Make Robots and Rocket Brand Studios. All are welcome of course, as well as your bots. It also looks like I will be the Big Chief of the Booth this year so feel free to drop me a line with questions etc., I am the "super head-guy coordinator guy of LMR at MF, guy".

Electromagnet Calculations

Hey guys, I think I really just need some help with Google search terms here...

I am making a solenoid, or more specifically, the coil part. I need to find an online calculator or some equations to figure out the proper gauge and number of wraps to give me a given resistance and/or strength. I am sure they are out there but for the life of me, I can not seem to put together the proper set of Google search terms to get me to where I need to be. I have been googling for over an hour now finding nothing of any use.

Drive Stepper (4th axis) off of PWM Spindle Control Ouput

Sorry 'bout this one, I am just sorta "thinking aloud" here, feel free to brainstorm with me, there is no real specific question here.

I want to use the 4th axis (horizontal rotary axis) as a lathe on my CNC. The X,Y,Z would operate normally, the only difference would be that they would be grinding away at a chunk of something spinning, as aposed to sheet-goods clamped down to the table.
