3D Printer Build Group 11 is here!

Build your very own 3D printer at Nova Labs!

The 11th 3D Printer Build Group is launching on December 9th, 2pm, at Nova Labs. On that date we’ll be putting together a kit that anyone can purchase, assemble, and turn into their very own Nova I3 3D printer. If you’ve got time to help assemble, please sign up here: https://www.meetup.com/NOVA-Makers/events/245247401/.

The 3D Printer Build Group meets every Monday evening from 7-9pm to assemble kits.

Kits will cost $450 for Nova Labs members, $500 otherwise, and may be purchased at any time, but will not be ready for pickup until the 9th. There will probably be kits available for some time after the assembly, but they are sold on a first-come first-serve basis. If you have any questions feel free to email Paul Chase – paenian at gmail dot com – or come to any of the 3d Printer Build Nights, every Monday evening from 7-9pm.

If you’re interested in joining the build group you can email Paul Chase: paenian at the gmail dot com


The printer we’re building is the Nova I3, which is a high-end printer for a mid-range price.
Features include:

  • Genuine E3D hotend, capable of printing high-temperature materials
  • Heated Bed
  • 24v motor and heater supply for high torque and fast heating
  • 200mm cubic build area
  • LCD & SD card for computer-independent printing
  • Available upgrade to dual-extrusion

The frames and 3d printed components are made right at Nova Labs; we’re also looking for volunteers to cut frames and print parts.

Laser Cutting

If you’re trained on the laser I could especially use help cutting – each kit comes from a single sheet of MDF, and takes ~40 minutes to cut. After cutting, the parts are stored in our boxes waiting for the kit assembly. Please contact Paul Chase, paenian at gmail dot com if you can spare some laser babysitting time 🙂

3D Printing

All the parts are printed by volunteers; they’re up on my Github page: https://github.com/paenian/i3_parts/tree/master/bg11

The full_plate.stl is everything needed for a printer, about 12 hour print on a BG machine. The other three plates combine to make the same parts if you have a smaller machine. Parts must be printed in (recommended) PETG or ABS; color is not important. Again, please contact Paul Chase, paenian at gmail dot com if you’d like to print a set or two :-)​

How-To: Using Raspberry Pi as a Streaming Music Player

raspi-music

Note: This “How-To” was originally presented by Cesar Picco as part of a Nova Labs partnership with GE Garages. Raspberry Pi is a $35 credit-card-sized computer.

Online streaming services are lowering the cost and increasing access to the music we love. But while the choice of devices needed to utilize these services are growing, they are still expensive.  After checking out pricey “audiophile” gear at my local neighborhood shop I was left asking the question:

Can I build one with a Raspberry Pi?

The Raspberry Pi (RPI) is a perfect transport for audio since it is very low cost, needs very little energy to operate and new open source software becomes available almost daily.  In addition to this, the Pi gives you three different audio output options on a board slightly larger than a credit card.

What you will need:

Hardware

  • 1 Raspberry Pi Model B
  • 1 USB Power Supply 5v micro USB
  • 1 SD Card 4GB or larger
  • 1 Ethernet cable (or RPI compatible Wi-Fi USB adapter)
  • 1 USB drive or NAS or some form of file storage device for your music
  • Powered PC type speakers 3.5mm headphone plug
  • Optional – Not needed if running headless
    • 1 HDMI Cable
    • 1 USB Keyboard
    • 1 USB Mouse

Software

Playing Audio from a Raspberry Pi

There are three different ways to play audio from a RPI.

raspi

Headphone Jack

The 3.5mm jack is not recommended by most due to pops and clicks. Now that I have said that, I use my headphone jack a good amount.

Rating: Fair

HDMI Output

HDMI is recommended if you have a newer audio amplifier that will accept HDMI audio inputs.

Rating: Better

USB Output

For high quality, use the USB output to a USB digital to analog converter (DAC).

Rating: Best

Setting Up the Raspberry Pi Streaming Music Player

Step 1

Create an SD card as the boot disk.

Step 2

Boot up and log in.

Username = root
Password = nosoup4u

Step 3

Squeezeplug has a very detailed video on their YouTube site.

  • Type “Setup”.
  • Select “OK” on the opening donation screen.

setup1

  • On the next screen select Yes, I like Squeezeplug.

setup2

  • Setup Home screen:

setup3

  •  Setup your server and player.  Select Server and Player then OK.

setup4

  •  Setup your server(s).  Select Install a Media Server then OK.

setup5

  • Setup your player(s).  Select Install a Media Player then OK.

I highly suggest Squeezelite and Shairport as good player options yet feel free to explore the other players.

Controlling Your Squeezeplug

There are multiple ways of controlling your Squeezeplayer, the easiest in my opinion is the standard app released by Logitech for their Squeezebox.  The software for the Squeezeplug is based on Logitech’s Squeezebox so their apps work very well to control these units.

The app can be found for Android systems at the Play store as well as at the Apple App Store.

One last step to controlling your Squeezeplug using the app is creating a Squeezebox account.

HARDWARE INNOVATION WEEK: Nova Labs “ProtoBoard” Speeds New Product Development

6975082682_de1e580a5a_z

What do you get when you combine an Arduino, a breadboard, and a standard cpu power supply on one convenient self-contained platform?

You get the Nova Labs “ProtoBoard”, an arduino-based hardware prototyping platform. Designed by Nova Labs Co-Founder Ted Markson, the project has been used successfully by members to develop their own hardware solutions.

The secret to this innovation is bringing together other available technologies and packaging it in a way that makes it more accessible and convenient for users.

The Nova Labs ProtoBoard features a laser-cut acrylic mounting plate and a cpu power supply interface board designed for compactness. Various voltages most often needed for hardware prototyping are provided: -5V,  -12V,  3.3V,  5V,  and 12V.

Interfacing the board with a standard computer power supply recognizes that in the DIY community, these power sources are ubiquitous and can easily be repurposed from old computers that most people already have lying around. This lowers the cost and reduces the time of sourcing alternative power sources.

The Nova Labs ProtoBoard is currently available only in very limited release. Email info@nova-labs.org for more information about getting one of your own!

We’re featuring Nova Labs hardware innovation all this week leading up to NoVa Maker Faire. Stay tuned!
