Well, the use of fuse ignition in the Build a $5 Heli-Rocket article from MAKE Volume 25 (also on Make: Projects), has caused quite a dust-up in the model rocket community. Use of fuses (as opposed to an electronic ignition system) is a no-no under NAR rules. So, don’t use fuses if you want to be safe and rules-abiding. Building a simple ignition system is easy (a great beginner electronics/soldering project) and if you want to keep it all seriously DIY, you can even roll your own igniters. In this Make: Projects piece we ran during Maker Hobbies month, Stefan Jones shows you how to make your own model rocket igniters out of lengths of nichrome wire and hobby lacquer.

Give your gadgets a brain! Previously out of reach for the do-it-yourselfer, the tiny computers called microcontrollers are now so cheap and easy to use that anyone can make their stuff smart. With a microcontroller, your gadget can sense the environment, talk to the internet or other hardware, and make things happen in the real world by controlling motors, lights, or any electronic device.
