Um Anel-Relógio! E Visão Nocturna, como vender Modelos 3D, controle com Pi, e Dobrem Tubo.

Ora aqui está uma pequena maravilha, um Anel-relógio, coisas que eram dos Filmes de  Ficção-Científica, há uns anos, agora, vocês fazem em casa, é só seguir as Instrucções!

ATtiny85 Ring Watch

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

Já podem, agora, com este Visor de Infravermelhos, que constróem em casa:

DIY Infrared Night Vision Device


 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, 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. 

Podem controlar o que quizerem, lá em casa, com um Raspebby Pi!
Sim, controlam uma série de Relays, assim, e ligam e desligam tudo o que tiverem para ligar e desligar. 
Vejam agora como: 

Controlling any device using a Raspberry Pi and a relay module

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. 

Sem serem o Bender, já podem agora dobrar Tubo à vontade, o que abre toda uma nova Gama de possibilidades, para Estruturas de toda a ordem...
Um Achado! 

Tube bender

I would have liked it to make a new seat for my recumbent bicycle and for it was necessary some aluminium tubes and to bend those on proper shape. In our town I have not found a place to bend some tubes and I have decided to make my own tube bender for this work.
