3DWebfier - WIFI to USB 3D printer remote control

3DWebFier Project - the spreading of 3D printers is giving hint to the creativity of many people, including myself, it's great to draw an object and then send it to to the printer, you will be fascinated to see how a thin wire, like raw material, fluid materialize your idea. But we realize that time is passing, for a complex object sometimes also needed from 6 to 10 hours before it is completed.

Thus we have a new requirement: it would be great if our 3D Printer can be remotely controlled from the office or from our car, check the progress of work and even stop in case of emergency. Ok, I know that someone has already thought this, you may decide to use the old laptop connected to the router of your home or office, or definitely the most easy, take a Raspberry PI as a front-end Internet for your printer 3D. Our idea is to use our development board PIC-AP BOARD (or any board with similar characteristics, a Microchip PiC24 such this one ) connected via USB to the printer 3D and WiFi to home router via a WiFi module with serial interface HLK-RM04 We use the sw free VSPM Virtual Serial Com on the laptop to map the ip address of the printer to a virtual com of our PC and we will control our printer with Pronterface, from another room, the office or from another city.

Indossa FLORA - The Wearable electronic platform: Arduino-compatible

 Flora Hand

 Pt 486

 NYC, Adafruit Lab, 

la tecnologia ormai entra ovunque,  con le soluzioni di LadyAda diventa indossabile per mille applicazioni, limitate solo dalla fantasia.

 

FLORA - Wearable electronic platform: Arduino-compatible -


For the last few years Ladyada has been thinking about everything she wanted in a wearable electronics platform for Adafruit's community of makers, hackers, crafters, artists, designers and engineers. After months of planning, designing and working with partners around the world for the best materials and accessories, we can share what we're up to. The hardware is now in the hands of our staff and testers!

We call it the FLORA.

Eagle

Adafruit created the FLORA from scratch after many months of research and we really think we came up with something that will empower some amazing wearable projects.



The FLORA is small (1.75" diameter). We wanted the smallest possible board for our wearable platform.

It's based on our experiences shipping our own, shipping, customer-tested Atmega32u4 Breakout Board.

The FLORA comes with projects at launch, the FLORA addressable and chain-able 4,000 mcd RGB LED pixels and premium stainless steel thread.

The FLORA has built-in USB support. Built in USB means you plug it in to program it, it just shows up. No additional purchases are needed! Works with Mac, Windows, Linux, any USB cable works great. Currently the PCB comes with a mini B connector but future versions may change to microUSB. Either will work great.

The FLORA has USB HID support, so it can act like a mouse, keyboard, MIDI, etc. to attach directly to cellphones. Our iPhone/iPad/Android app coming soon.

The FLORA's modules include: Bluetooth, GPS, 3-axis accelerometer, compass module, flex sensor, piezo, IR LED, push button, embroidered + capacitive keypad, OLED and more.

The FLORA has a small but easy to use onboard reset button to reboot the system.

The FLORA is fabric friendly. The FLORA does not use FTDI headers (built in USB support) headers of any kind sticking out can grab and tear fabric.

The FLORA has an onboard 3.3v 100mA regulator with protection schottky diode and USB fuse so that power is consistent and can power common 3.3v modules and sensors.

The FLORA has onboard polarized 2 JST battery connector with protection schottky diode for use with external battery packs from 3.5v to 16v DC in. Can be used with LiIon/LiPoly, LiFe, alkaline or rechargeable NiMh/NiCad batteries of any size.

The FLORA does not have a LiPo charger included by design, this allows safe use with multiple battery types and reduces risk of fire as it is not recommended to charge these batteries on fabric.

The FLORA has onboard power switch connected to 2A power FET for safe and efficient battery on/off control. Often FETs are not included in other designs that leads to switch failure as small SMT switches are rated for only 20mA current use.

The FLORA power system is specifically designed to allow easy control and power of a large quantity of digital RGB LED pixels such as the FLORA pixel series of accessories.

The FLORA is extremely beginner-friendly - it is difficult to destroy the FLORA by connecting a battery backwards due to polarized connector and protection diodes. The onboard regulator means that even connecting a 9V battery will not result in damage or tears.

The FLORA has 4 indicator LEDs: power good, digital signal LED for bootloader feedback, data rx/tx.

The FLORA has an ICSP connector for easy reprograming for advanced users.

The FLORA has 14 sewing tap pads for attachment and electrical connections. Data buses are interleaved with power and ground pads for easy module and sensor attachments without worrying about overlapping traces which are not possible with conductive thread.

The FLORA works with the Adafruit-fixed Leonardo bootloader (not released) and will work with any future released Leonardo-compatible bootloader. FLORA is currently using our Adafruit bootloader and Adafruit USB vendor ID.

The FLORA comes with Adafruit's support, tutorials and projects. Adafruit has dozens of projects that will be released with the FLORA in 2012 and has staff 100% dedicated to creating tutorials and projects for use with the FLORA.

The FLORA is made in NYC at Adafruit, it was designed by Limor Fried (Ladyada) she is an Electrical Engineer with a proven track record of providing over 26 high-quality libraries for Arduino/Arduino IDE, over 100 tutorials, open-source code and contributions to the Arduino project. She was a member of the MIT wearables group and likes to sew.

Controlling a digital camera via USB port, now with a Microchip PIC24 family microprocessor





Now with a PIC processor (24 or 32 of the Microchip family) you can control a camera that automatically execute many commands with a system based on a Microchip microcontroller functions with USB Host / OTG embedded.

NEW:
 tested on:
Nikon Coolpix AW100
Nikon D50
Canon Powershot A300
Canon Poweshot S500





The basis of the project 

Always been passionate about photography and electronics, i tried to combine my two hobbies in order to explore new filming techniques and high-speed, with the help of automated systems. The first problem 'was born as camera manufacturers often do not disseminate technical information on the functions of their internal models. Inspired by some of Arduino projects, (particularly that of Alex Glushchenko) and Linux (http://sourceforge.net/projects/libptp/, http://libptp.sourceforge.net/README) after months of work with a friend more skilled than I in C programming, we have designed and built a prototype that implements some USB host control functions of digital cameras via USB PTP protocol, using the embedded functions available on a PIC24F.Compatible between brands and models (PTP functions are not implemented in the same way), we tested some compact DSLR Nikon and Canon. The commands more 'interesting to implement for the photo enthusiast are: 

1) Remoting of the shutter button (shutter) 

2) Set / Read values ​​of shutter speed, aperture, etc.. 

3) Interval (Time Lapse)

4) Remote control of motorized lens focus, depending on the cameras. 

5) Bracket (for cameras that provide the function) to perform post-processing in HDR. For those not aware, the bracketing feature (usually found on DSLR) cameras in the shows "varied exposure bracketing", this includes the performance of at least 3 photos in sequence separated by a value of over-and underexposure (longer and shorter than expected) that allows you to "hit" the perfect photo or obtain a particular effect with special software, HDR (High Dynamic Range) by superimposing the three images (eg HDR). 

The ability to remotely activate many functions (but especially the shot) on digital cameras make possible many photographs sometimes impossible or at least difficult to achieve with the traditional method because of human reaction times.I refer to as jerky in the world of high-speed photography '(fall of a drop of water or other liquid, explosion of balloons, etc.) or techniques of photography on a regular basis (even several hours) as the time-lapse (for example, to record the blossoming of a flower or the hatching of an egg) and 'easily achieved by combining this system with appropriate sensors, motion, light or sound

If you are interested in Remote Shooter assembled and tested, with LCD display, you can find it on Ebay Italy

Description of the prototype and function blocks.


We start with the description of the prototype starting its functional blocks. To work in the field the system must be powered by batteries and consume very little. The first checks the entire system consumes about 90mA with peak and 110mA when 'the backlight of the LCD display (timed and controlled directly from an output pin of the microcontroller).
Now let's see in detail the individual functional blocks:



The first block consists of a PWM Step-Up DC-DC converter (NCP1450) with 2 AA batteries, which brings the voltage to 5 volts, with about 800mA max load. The chip 'was chosen because' it is quite efficient (88% max) and can 'work with input voltages from 1.5 to 4.2 volts. Though the CPU and also the LCD display (including backlight) work at 3.3 volts, the voltage to 5 volts is required for USB host functions and to power sensors or external circuits.
Carry the basic layout of the chip that we used in the prototype.


 
The second block is represented by a classic low dropout regulator (Reg1117) which reduces the voltage to 3.3 volts.Top right we have the three buttons that perform the function of navigation and choose from the menu that appears on the LCD 8x2 (double row connector on the left, with adjacent trimmer contrast).At the center of the PCB we PIC24FJ256GB106 the processor that has a quartz oscillator clock at 20MHz and 72MHz internal PLL configured. For programming and 'was prepared ICSP port (bottom left), as a programmer / debugger use the PICkit2 and 3 with the Microchip MPLAB sw.On the right we find the USB port in Host Configuration and down, centrally located, two rows of connectors for expansion I / O and any communication with sensors / devices or I2C serial (with appropriate external level translators).The prototype had a lot of potential '(the chip and' one of the most powerful and complete PIC24F family with 16Mips power, a lot of memory and 64-pin) can 'be used not only for the purpose for which and' born, but also as a tool development, and 'Simply use the expansion port to connect an analog voltage to be measured or PWM outputs to activate motors etc..Despite some concerns 'Initially, it was' chosen to achieve all or most of the PCB in SMD technology. The questions consisted of mounting a successful prototype SMD having no virtually no previous experience in this technique, and even more 'no technological means as this, and' a hobby for us. In fact the problem 'was brilliantly and in a few minutes, with the technology of the electric cooker at about 210 ° C and the miraculous solder paste that makes everything very simple, the constituent assembly formed in 0805 to 64-TQFP processor pin.Gli any short between pins of the chip during cooking were removed using desoldering braid flux and everything and then tested with the tester.Stages of assemblyThe prototype already 'welded during assembly, ready for the first functional tests (power supplies, buttons, displays etc.)


The prototype boxed and ready for the first field tests.


For communication with external sensors we used a DB9F connector which brings out the power supply to 5 volts and some pins of I / O. 

The test image shooting camera when the sensor detects the interruption of the laser beam.

Setup based on a laser pen (left) and LDR (right) with attached Schmitt trigger circuit (with a 74HC14)
