Freaks3D is a Low Cost Portable 3D Printer (Crowdfunding)

July 31st, 2015 7 comments

ElecFreaks is a design house based in Shenzhen that caters to makers and startups, and started selling Arduino shields and accessories, as well as  Raspberry Pi add-on boards, before moving to robotics kits, 3D printers, and other tools in demand by electronics hobbyists. The company has now designed Freaks3D portable 3D printer, and launched an Indiegogo campaign to fund production.

Freaks3DFreaks3D printer specifications:

  • Technology – Fused Deposition Modeling
  • Build Volume – 130 x 150 x 100 mm (LxWxH)
  • Nozzle Size – Standard 400 microns
  • Resolution – Layer: 100 microns; XY: 50 microns
  • Filament diameter – 1.75mm
  • Filament Material – PLA or TPU
  • 3D Files Transfer – USB via PC, or SD card
  • Misc – LCD Display, one button operation, printing bed does not require heating
  • Power Supply – 12V / 8A power adapter, or 12V / 5A power bank (Not included)
  • Dimensions –  290 x 320 x 325 mm
  • Weight – 2.945 kg

The company recommends Cura or Repetier Host software, available for Windows, Linux, and Mac OS X,  work with the printer which supports stl, obj and G-Code files.

They also compared Freaks3D to the more expensive, but in many ways similar, Replicator Mini and Ultimaker2 Go compact 3D printers.

Freaks3D_vs_Ultimaker_vs_Replicator_MiniThey left out some details being more favorable to the other two models like WiFi connectivity and on-board camera to monitor printing progress in the Replicator Mini, but on paper at least Freaks3D appears to be a fairly capable printer for the price.

You can also watch a 15-second video to see the printer in action, with close ups on the object being printer, and LCD display.

With 16 days to go, the campaign has been successful so far with about $114,000 raised from 400 backers. The cheapest reward is $299 for the printer kit to be assembled and a 8GB SD card, but if you prefer an assembled unit and 3D filament, you’ll need to pledge $399. Delivery is scheduled for August 2015, with free shipping (by boat) to the US and Europe [Update: There seems to be confusion with shipping as backers from some countries in Europe are asked to pay $30 to $40], and to other countries you’ll need to contact Elecfreak to find out how much you need to pay for shipping.

I got clarification for shipping:

For the Freaks3D fully assembled, shipping to the US and Europe costs 40 usd/unit; For the Freaks3D kit form, shipping to the US and Europe costs 30 usd/unit. Customers in other areas of the world, we will contact them later after the campaign closes to charge the shipping cost because at the current stage, we’re picking up the most affordable and best forwarders for the 3D printers, and some customers ask for air shipping while others prefer cargos.

If you’d rather not order through Indiegogo, Freaks3D printer is also up for pre-order on ElecFreaks website (The $599 price tag shown is not the final one…). There’s also a very similar model called Creality CR-7 selling for $220 + shipping on Focalprice.

Gesto is a Wearable Gesture Motion Solution for Makers (Crowdfunding)

July 5th, 2015 No comments

A while ago I wrote about an open source prosthetic arm controlled by signals generated by your arm’s muscles. It used an Arduino board, a bio-feedback shield by Olimex, and inMoov Hand for the arm and hand. It worked, but lacked accuracy. Gesto is a solution based on boards powered by Atmel MCUs that looks somewhat similar, but with higher accuracy (over 100 gestures have been tested), and the project has now been launched on Crowdsupply.

Two kits are available:

  • Gesto Stella Gesto Stella
    • EMG circuit – ADS1294
    • MCU – Atmel ATmega1284p
    • 2x EMG cables connector
    • Through holes with GND, PWR, MOSI, MISO, CLK and SC
    • Dimensions – 35 x 20 mm
    • Includes 16 disposable electrodes and relevant cables
  • Gesto Caelum
    • EMG circuit – ADS1294
    • MCU – Atmel ATmega1284p
    • Sensors – 3-axis accelerometer (MMA8652FC)
    • Connectivity – Bluetooth (RN42-HID)
    • 2x EMG cables connector
    • USB – Micro USB connector
    • Programming – ICSP connector
    • Power – Battery connector
    • Dimensions – 40 x 40 mm
    • The kit also includes 8 reusable dry electrodes with cables, a 3.7V rechargeable battery, a micro-USB cable for recharging, and an elastomeric band. The smartphone setup app and a 3D model for a modular band will also be provided.
Gesto Caelum

Gesto Caelum

Gesto Stella is designed to interface to other boards such as Arduino or Raspberry Pi boards, and sends raw muscle data via its SPI interface. Gesto Caelum is more of a standalone, ready-to go solution, as it integrates Bluetooth communication, so you can simply configure the gestures in your Android or iOS smartphone to get started right away.

Prosthesic arm controlled with Gesto

Prosthesic arm controlled with Gesto

Gesto can handle three types of gestures: singular gestures (static), air drawing gestures, and directional gestures (rotations, up and down, etc…). The technology making sense of the muscle raw data is called “DualBurst” which combines muscle patterns and motion patterns for better accuracy. I assume motion patterns are not available with Stella, but only with Caelum. An SDK, smartphone apps, and 3D printer file (for arm band) will be provided.

Gesto Stella costs $99, and Gesto Caelum $149, with delivery scheduled for March 2016. Shipping is free to the US, and $15 to the rest of the world.

Blacksmith Genesis is an Affordable 3-in-1 3D Printer, Scanner, and Copier

February 20th, 2015 No comments

Multifunction printers have been commonplace for many years, and allow you to print, scan, or copy any document with or without your computer, but when it comes to 3D is a little more complicated. First, it’s usually quite harder to design a 3D object than typing some text into a word processor, although 3D objects online database like thingiverse do help. If you want to copy a 3D object, you may have to buy a 3D scanner such as MakerBot Digitizer, and a 3D printer such as Makerbot Replicator 2 which takes space and costs about $3,000 in total. Multifunction 3D printer are slowly coming to market with for example AIO Robotics Zeus which recently shipped to backers, and is now available for $2,500. An other option is Singapore made BlackSmith Genesis, a compact multifunction 3D printer that can print, scan, and copy objects based on a rotary design, that successfully completed a crowdfunding  campaign last year, and is now taking pre-orders for $2,200 + $150 shipping max for June 2015 delivery.

3D_CopierBlackSmith Genesis technical specifications:

  • Printing
    • Technology – Fused deposition modeling with rotary platform
    • Build volume  – 6648 cm3 (23 cm diameter / 16 cm height)
    • Layer resolution – 50-200 microns
    • Filament – PLA 1.75mm diameter
    • Nozzle diameter – 0.4mm
    • Print file type – .STL, .OBJ
  • Scanning
    • Technology – Laser triangulation
    • Scan volume – 5542 cm3 (21cm diameter / 16 cm height)
    • Scan speed – About 6 minutes
    • Steps per rotation – 1,200 steps
    • Camera – 3.1MP CMOS Image Sensor
    • Exported file type – .STL, .OBJ
  • Interfaces – USB, SD card, and Wi-Fi (WiP)
  • Power Supply – 100-240W / 50-60Hz / 100W
  • Dimensions – 35 x 25 x 41 cm
  • Weight – 11 kg (Indiegogo), but they’ve now reduced the weight to 6kg

The printer-scanner is controlled via a web-based software bundle called Blacksmith Sorcerer. The camera for the scanner can also be used to remotely monitor the printing progress via your smartphone or tablet. The video below demonstrate the main features of the printer.

Hall of Shame

Last year, it was clear FocusWill Coolship project was a disaster, and the project owner clearly did not deliver the goods and kept silent. This year, I could not find project that I’m 100% sure failed with money being lost, but at least Plugaway Wi-Fi smart sockets could be a project where backers lost their money. The sockets were supposed to be delivered in March 2014, but nothing so far, and the last update in November is only about the API, nothing about delivery despite backers complains.

AFAICS, nobody lost money with Com1 Android Wear smartwatch, but they should have known better, as Google asked Indiegogo to take the project down, because only Google partners can develop and manufacture Android Wear devices.

Stats and Projects Delays

Out of the 55 campaigns, 15 project failed to reached their funding targets. Most projects without a successful crowdfunding still carried out, with 4 to 6 projects completely dead. That means 72% of projects got funded via crowdfunding, 90% of projects get manufactured (assuming the ones still under development will succeed). AIRTAME got the most funding with over $1,200,000 raised, but has not been so successful in terms of product delivery with 8 months delay.

Many projects are delayed, but Smart Socket Strip may take the delay crown, with a massive 1-year delay for the project, and backers upset of the constant postponing (or lies) about delivery dates. Fin Ring is also pretty bad, as the September 2014 promised delivery is now expected to occur on May 2015.

Hall of Fame

This year several project managed to deliver working products on time, although sometimes shipping was have taken place over a few months.

  • IteaDuino Lite Arduino clone was delivered right on schedule just a year ago.
  • MicroDuino JoyPads were delivered on November 2014 as promised
  • The first version of Console OS Android operating system for PC was released on December 2014.
  • STACK Box Home Automation / IoT Gateway were sent in December 2014. There aren’t many feedback for now, as most people are still waiting for delivery, or have just received their device.

Many other projects shipped with just one month delay, and still got good user feedback, and an active community around them, such as Micro Python, LOGi boar, VoCore Wi-Fi module, NavSpark. MicroView was also on schedule, and even slightly ahead of schedule, but unfortunately, Sparkfun shipped several boards without bootloaders, and they are still handling the returns.

That’s all for today. If you’ve had good or bad crowd-funding experiences, feel free to share them in the comments section.

Opendive – Low Cost DIY Open Source 3D Virtual Reality Kit for Smartphones

March 17th, 2014 2 comments

About 10 days ago, I wrote about solution to record and play 360 degrees panoramic videos. One of the itmen was vrAse virtual reality case for your smartphone, and allows you to enjoy immersive 3D experience. If you’d rather do your own, than buy a kit for about 100 Euros, there’s an open source project called OpenDive that does about the same thing, and allows you to play games in 3D.
opendive

All you need to do is to download the 3D files, print the head-mounted glasses it with your 3D printer, and buy the lense kit (6.99 Euros) to get a complete working system. You may have to modify the design, and adapt it to your phone dimensions. And if you don’t have a 3D printer, somebody provided instructions to do your own by cutting wood or plastic sheets. You then should be able to watch 360 deg. panorama videos, and play 3D games (See current list) as shown in the video below:

If you are a game developer (iOS or Android), you can use the Dive SDK to make your games support the glasses.

More information can be found on Opendive page. There’s also a commercial version called the Dive.

Thanks to Matthias for the tip.

Open Source Prosthetic Arm Controlled By Muscle Movements

June 24th, 2013 7 comments

Gustavo Brancante is working on a very interesting project that let you control a prosthetic arm with your muscle movement using open source technology with InMoov Hand (which can be 3D printed), Arduino Uno R3, and Olimex Electrocardiography electromiography shield (SHIELD-EKG-EMG). This is called a Myo-Electric Prosthesis.

Open_Arm

Gabriel wrote a tutorial to use his “open arm” which I’ll summarize here.

On the hardware front, you’ll also need a UDP compatible Wifi Shield configured as a UDP server with a fixed IP in the same LAN as the smartphone, and 57600 bps.

TouchOSC (for smartphone and Workstation) is used with the following layout for calibration and feature selection.

Finally load the program below to your Arduino board:

Once everything is connected together, you should be able to do that:

The demo looks impressive, but this is still work in progress, and next step will be to use a four channel EMG instead of the single channel Olimex EMG shield to be able to detect more advanced movements.

PengPod 700 Linux Tablet Used As a 3D Printer Touchscreen Controller

April 6th, 2013 1 comment

PengPod 700 & 1000 are two of the rare Linux tablets to be available on the market. Those tablets are based on AllWinner A10 SoC which can support both Android and Linux thanks to independent developers. After a successful Indiegogo campaign, where they managed to received pledges for a few hundred units of both model, people started to receive their Linux tablets earlier this year. Francesco Santini decided to purchase PengPod 700 in order to use it as an touchscreen controller for his 3D printer (Solidoodle).

Pengpod_3D_printer

He modified Pronterface, a graphical user interface written in Python to control 3D printer, for the 7″ display the of PengPod tablet, and made the change available in his github account https://github.com/fsantini/Printrun-pengpod700.

Pronterface

He uses a SAMBA share to copy G-code files (“G-code is the common name for the most widely used numerical control (NC) programming language”), and load the required file from the PengPod using the interface above.

He also created the holders to mount the tablet on the printer, as seen in the picture at the top, and uploaded the design files to http://www.thingiverse.com/thing:69593, which can be good if you need a stand for your tablet, whether you have a 3D printer or not.

You can find (or ask) more information on Soliforum.

Replicate CAPE Adds 3D Printring Capability to the Beaglebone

February 2nd, 2013 No comments

Beagleboard.org launched the Beaglebone Cape Design Contest back in November, several designs were submitted, and yesterday, they announced the 3 winning CAPEs who will be manufactured and sold by Circuitco Electronics:

  • Replicape by Elias Bakken – 3D printer cape
  • Interacto by Chris Clark – Cape with a triple axis accelerometer,a gyroscope, a magnetometer and a 640×480 30fps camera.
  • Geiger cape by Matt Ranostay – Geiger counter cape

Since today I’ve started to write about 3D printing, let’s carry on and have a closer look at the Replicape.

Replicape

The Replicape 3D printer cape includes:

  • 5 stepper motors (X, Y, Z, Ext1, Ext2)
  • 3 high power MOSFETs (PWM controlled) for 2 extruders and 1 HPB
  • 3 medium power MOSFETs (PWM controlled) for up to 3 fans
  • 3 analog input ports for thermistors
  • 3 inputs for end stops (X, Y, Z)
  • Programmable current limits on steppers motor drivers (SMD). No need to manually adjust a pot meter.
  • Microstepping individually programmable for each SMD from 1 to 32.
  • X, Y and Ext 1 SMDs wired to PRUICSS for hard real time operation.
  • Option for stackable LCD cape

It seems to be working, albeit slowly, as a control board for the Makerbot Cupcake.

The replicate hardware files (schematics, bill of materials, gerber files), and the source code (Python and C) for the PRU and controlling stepper motors, are available on Bitbucket. So you could make it yourself, or buy the Replicate from Circuitco when it’s available, and improve the source.
