Pocket Pi - a Raspberry Pi Computer for Under $150
TheInventionMaker

This is a affordable $100 raspberry pi computer. This computer is not the thinnest or prettiest thing on instrutables. This is for getting the job done. The shell is 3D printed. There is 1 charging port, for the motherboard. The keyboard has a wire designated for charging the keyboard and will not be noticeable on the outside. There are 3 USB 2.0 ports are for input. 1 will be used by your bluetooth + wireless USB stick. Luckily, I have included a USB holder that holds your USB's.

The screen is 4.3 inches and is not a touchscreen. You can easily make it touch screen compatible. The raspberry pi is a zero. This is because the Adafruit Kippah currently does not support the zero w. You will still need a wifi network! It runs NOOBS, but you can still download PC games on it. All you have to do is to search on google how to install PC games on NOOBS.

You can use this to check up on things, play games, and use applications that are normally on PCs. It can do a lot of things that phones can do, but the computer is significantly cheaper. The parts are spread across 3 different websites. If you do not have a 3D printer or a soldering iron, you will have to but different parts. This will be explained in the steps. It should take you around 1 hour to build, but with shipping times and how long your 3D printer takes to print the parts, it could be longer.

A Pocket $200 Night Scope, now, that sounds real Neat!

3D Printed Night Vision Scope

Happy_Mad_Scientist

Hey everybody!!! Hows it going?!?!?! Ok, so for a long time (~3 yrs.) I have been building these digital night vision cameras, and after over $1,000 and hundreds of hours in R'n'D later, I give you the "Eagle Scope 1.0" (named after the camera inside)!!!
It's a pocket-sized, 3d printable night vision monocular that you can build yourself for ~$200!!! Oh, and it is top of the line, sporting a near-eye display (that doesn't burn out your eyeball), a .00001 lux camera with an OSD, a rechargeable 3hr battery, and an (optional) external DVR for recording the footage!!! Best of all, it fits in your pocket!!! Over-enthusiastic!!!!!! But seriously, this thing kicks some major buttocks.

Um Motor feito com Ímanes Permanentes, que é um Anel, com a Hélice no meio!
Vejam o Vídeo, para perceberem as vantagens dum tal Sistema, que vale a pena...

Rolls-Royce | Permanent Magnet Technology

The AZ-PM thruster is the latest in a range of Rolls-Royce propulsion products using its permanent magnet technology. This technology is based on electric drive where the motor is in the form of a ring round the propeller. The moving part of the ring is a rim around the propeller blades which carries a series of strong permanent magnets. The rotor, fitted within a series of magnets, turns within an outer ring which form the stator. When current is supplied to the motor from the variable frequency power supply the electromagnets are excited in a particular sequence and the resulting magnetic fields interact with the field from the rotor magnets creating a torque that turns the rotor and its propeller blades.

ATtiny85 Ring Watch

陳亮 

Based on the previous Instructables - ATtiny Watch Core and more, I have made a real gadget, an ATtiny85 Ring Watch.

MCU

Today core subject, ATtiny85. Someone suggest me to use SOIC version to reduce the watch size and I found the coin cell mAh calculation method will count the battery voltage down to 2.0 V, so this watch require a low voltage version MCU to keep it stable. So I have ordered an ATTINY85V-10SU. (much expensive $_$)

DIY Infrared Night Vision Device

eyebot117

 I've been involved with airsoft for about two years being affiliated with a large local group of people in our community who meet regularly and have scheduled games, ops, and events. Airsoft is a great sport and hobby that encourages teamwork, honor, respect, communication, and discipline (as well as how to wisely make purchases). I recently played a game at night and realized how cool it would be if I could utilize some form of night vision. The more I researched it, the more I wanted to see in the dark somehow.

Unfortunately, true night vision in even the lowest quality can cost hundreds of dollars just for the optic alone, excluding hardware necessary to mount the optic to a helmet or airsoft rifle. It's expensive technology. However, there are alternative methods for seeing in the dark. There are several versions of educational night vision viewers and toy spy binoculars available on the market for kids and...um...well, geeks like me. They utilize low-lux cameras, infrared illumination, and a display for a more affordable $50-$80 system that can still see in the dark. This is the system I chose to utilize.

Being inspired by DIY'ers like Kipkay, and reading books like 50 Spy Gadgets for the Evil Genius, I chose to invest the money to build my own infrared night vision viewer. Besides, both of those night vision builds use parts that can only be scavenged, not purchased individually. I wanted to show how to build a unit from stuff you can buy online easily or at the store.

Pinshape 3D Printing Design Guide: Learn How to Sell Your Models

Bridget Butler Millsaps  

Sometimes the world of 3D printing still feels a bit like the wild, wild west. The rules are being made up as we go, and it’s still a fairly lawless frontier, as well as one where you, well, sometimes just have no idea how to pull off a particular concept, or no earthly idea why something went wrong when you were in the throes of creativity, bringing a supposedly great design to fruition. And of course, when things do go stupendously, we want to share. Thank goodness now for the talented—and generous—souls in the Pinshape community, who have offered up all of their tips, now compiled in their ­­­­­­­­­­­­­­­­Pinshape 3D Printing Design Guide.

Controlling any device using a Raspberry Pi and a relay module

julienrl 

The goal of this ible is to show how to get started with setting up a relay module on your pi and controlling it. My goal is to add scripts to my octopi to turn on and off LED lights, but anyway you decide to eventually control the GPIO commands, the setup is the same.

Raspberry PI night vision goggles.

mr_fid 

Very simple and cheap Infra-Red night vision googles, using a model A raspberry pi, a NOIR camera and Quanum FPV Goggles.

For a while now I have been playing with Multicopters, and whilst I prefer to make the models myself and fly them properly with a transmitter, I couldn’t help being interested in First person View (FPV) so I got a camera and transmitter and a small monitor. My first attempt didn’t end well I took off the model by sight and the monitor was in the back of the car. Then when I was happy I took my eyes off the model and looked at the small monitor, I flew for about 30 seconds then looked up…… I hadn’t got a clue where the model was! When I finally spotted it I couldn’t work out which way it was facing and flew it into a tree!

After that poor attempt I wondered if goggles would be a better choice so I had a look on line and found that the decent goggles are a lot of money, then I saw the Quanum goggles and at £32 a thought they were worth a go.

Very cheap Delta 3D Printer (about 150€)

A year or so, i began to interested about 3D Printers. Then, i started to look for information about this, how they are working, how they are made…

When i was prepared, i started to buy the pieces for to do my own 3D printer, it should be a delta type, because i like how it moves, but the downside of this is the calibration…

A First Look at the RePhone, a Modular Cellphone You Build Yourself

Alasdair Allan 

Today SeeedStudio launched an intriguing new Kickstarter project, the RePhone. Reminiscent of Project Ara, Google’s much hyped but continually delayed effort to build a “hardware ecosystem” around smart phones, the RePhone is a modular phone built from open source components.  

The core of the phone is provided by the RePhone Core GSM + BLE module, or by the RePhone Core 3G module, which provides a faster data connection but lacks BLE support. However, beyond these two core modules offering the cell connection are 8 more add-on modules from Seeed’s Xadow range — a 1.54-inch touch screen, a 5×7 LED board, an NFC board, a GPS board, an audio board, a basic sensor board, a GSM breakout board and an Arduino-compatible microcontroller.
