Impressora 3D dos Instructables! E um medidor de pulsação, um Kit Espacial, e um projector Raspi

E que tal construírem a vossa própria Impressora 3D?

Eis uma forma de terem em casa uma Impressora 3D por muito pouco...

Homebrew Arduino Pulse Monitor (Visualize Your Heartbeat)

ASCAS

Movies look cool with those EKG (electrocardiogram), the one that beeps and detects heart activities. A few months ago, we had to shoot a hospital scene for our school project. We needed an EKG instrument. To keep the movie authentic, we didn't want to fake the readings so we made the next best thing, a pulse monitor. Since my dad is a doctor he gave me some advice to design the pulse monitor.

E com este Projector, Impresso em 3D, e com Raspberry pi, podem fazer uma data de Multimédia, bastando-vos arranjar uma Lanterna LED decente...

É bom!

Augment Your Reality With The iTorch raspberry pi flashlight projector

This Instructable is for a prototype homemade projector that can be illuminated by any decent LED flashlight/floodlight.

This is my first published instructable so please leave comments and/or suggestions! Any feedback is very welcome and I will try to respond to everyone as soon as I see it!

At this stage the iTorch is a kit that I hope to be able to make available if I were to somehow get my hands on my own laser cutter. I have been spending a good amount of money using school equipment to laser cut this project, and got a quote to use the 3d printer and the price was astronomical. So needless to say a laser cutter and 3d printer would go to good use and be greatly appreciated.

Though you could probably reverse engineer one of your own. ;)
