Thanks! I've got some neat costume projects going on right now but it'll still be a bit before they're done. I rough out all my ideas on paper first- sometimes I fill entire sketchbooks with just one project working out different construction methods and design details. For software I use a few different programs, most of which are free.

For 3D design there's Blender http://www.blender.org and 123d http://www.123dapp.com/

For electronics I use Eagle http://www.cadsoftusa.com/eagle-pcb-design-software/?language=en&lang=en for PCB design and Fritzing http://fritzing.org/ for drawing schematics

For drawing on the computer I use SketchBook Pro http://usa.autodesk.com/adsk/servlet/pc/index?id=6848332&siteID=123112

One program I've found extremely useful for designing linkages and mechanical systems that move is ForceEffect Motion https://itunes.apple.com/us/app/autodesk-forceeffect-motion/id512045820?mt=8

Just let me know if you have any other questions!

Thanks!

Are you on the RPF? I have an Iron Man suit animatronics build thread there. Should be done with it soon!

Thanks! I'll have an instructable when the suit is finished. :)

Hopefully I'll have some new stuff soon- I've been super busy with multiple projects, the latest of which is here- http://multi-bot.blogspot.com Unfortunately I'm never on the forums since I just don't have the time- with three kids I barely have enough time to try and work on my own projects.

Thanks! Hopefully I'll have it finished soon- I've got a bunch of stuff I need to get working on for Halloween. :)

A lot of it depends on what materials you can find for free. I know I spent well under $100
