3D printers for the home usually cost between few hundred dollars to several thousands depending on the model, but OLO 3D Inc. has created a $99 3D printer that prints objects using your smartphone screen and photopolymers (aka daylight resins) that harden with light. The printer itself is divided into two main zones: the bottom printing chamber where you’ll pour the liquid resin, and the top with the motor and four AA batteries that power the device. You’ll first need to install OLO 3D Android or iOS app in your phone, load a 3D object either from a library, created with 3D software, or scanned with apps such as Autodesk 123D Catch, set your phone in airplane mode with WiFi disabled, connect it to the power adapter, place it in a bed at the bottom of OLO printer, and tap on print. Now place the printer bed and printing chamber, […]
ZeroPi is an Arduino & Raspberry Pi Compatible Motor Control Board (Crowdfunding)
Pi boards keep on coming… As soon as I finished writing about Roseapple Pi board, yet another one popped out on my twitter feed… But that one is of a different kind, as it won’t run Linux, but instead the board is powered by an Atmel SAMD21 Cortex M0+ micro-controller, and can support lots of electric motors including up to 11 micro servos and 8 DC motors – or 4 stepper motors – simultaneously. ZeroPi board specifications: MCU – Atmel SAMD21J18 ARM Cortex M0+ @ 48 MHz with 32 SRAM and 256KB flash I/O pins via 33-pin header, 4-pin temperature sensor, and 10-pin Raspberry Pi header 35 GPIOs 4x 12-bit ADC channels 1x 10-bit DAC 2x UART 2-channel temperature sensor interface DC current per I/O pin- 7mA DC / Stepper Motor control – 4x 4-channel SLOT interface compatible with common parts such as DRV8825 or A4988 Stepper motor driver and […]
Freaks3D is a Low Cost Portable 3D Printer (Crowdfunding)
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. Freaks3D 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 […]
Gesto is a Wearable Gesture Motion Solution for Makers (Crowdfunding)
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 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 […]
Blacksmith Genesis is an Affordable 3-in-1 3D Printer, Scanner, and Copier
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 […]
Crowdfunding Report for 2014 on CNX Software Blog
Following up on my 2013 Crowdfunding Report, I’ve gone through all 55 Kickstarter and Indiegogo crowdunding projects featured on CNX Software between December 2013 and November 2014 (inclusive) to see how well they fared. The table below sort projects chronologically as they were published on this very blog. Date Project Crowdfunding Site Funded? Pledged amount / Goal Expected Delivery Actual Delivery Comments 2. Dec. 2013 Micro Python Kickstarter Yes 97,803 GBP / 15,000 GBP 03/2014 04/2014 Available @ https://micropython.org/store/#/store 5. Dec. 2013 Plugaway Kickstarter Yes $162,835 AUD / $50,000 AUD 04/2014 – People upset because of lack of updates. Project might be dead, and backers lost their money 6.

Opendive – Low Cost DIY Open Source 3D Virtual Reality Kit for Smartphones
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. 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 […]
Open Source Prosthetic Arm Controlled By Muscle Movements
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. 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 […]
