ONO, $99 Smartphone-Powered 3D Printer

Born in 2014 from the simple idea of making 3D printing accessible for everyone, Filippo Moroni and Pietro Gabriele worked on new technology to develop a high quality 3D printer that was affordable and easy to use. Their goal was to make the most diffused printer in the world and to develop a worldwide community around it. After 2 years of hard work, ONO has developed and grown into the first 3D printer of its class. ONO is the first ever smartphone-powered 3D printer that depends on your smartphone screen resolution in its printed outputs.

Similar to DLP (Digital Light Processing) resin printers, ONO needs light to harden the resins. But instead of using an embedded source of light, it uses the light of your smartphone screen to power the operation. Thanks to the customized patented resins ONO uses, they can react perfectly to white light coming from your phone, thus there’s no need for ultra violet light that is used for resin printers. All you need to do is to place your mobile on the phone pad and ONO will do the rest.

ONO has the following components:

  1. LED interface – The logo on the top of the printer flashes to show the status of the print
  2. Motor housing – The top part of the printer which controls the raising of the build plate
  3. Z-axis actuators – Drive gears connected to the motor and the build plate
  4. Build plate – Aluminum plate where the part adheres
  5. Resin tank – Removable tank where resin is poured prior to printing
  6. Printing film – Thin, clear film which seals the resin tank
  7. Adjustable base – The base can be raised or lowered so that the phone screen will sit flat against the printing film.
  8. Phone pad – A soft pad that helps level phones with protruding cameras

 

The affordable $99 3D printer is portable and can be charged using any USB charger whether connected to wall plugs or a power bank. You can clean ONO easily thanks to the removable resin tank and the printing films.

ONO has the following specifications:

  • Printer Dimensions: 180 x 128 x 185 mm – 7.0 x 5.0 x 7.3 in
  • Printing Volume: 124 x 72 x 52 mm – 4.8 x 2.8 x 2.0 in
  • Phone compatibility: Any phone with a screen size below 5.8”
  • Accuracy: Up to 42 micron XY resolution, Up to 100 micron Z resolution
  • (XY resolution depends on the resolution of the phone screen.)
  • Printing Speed: 12 mm per hour

It’s a simple process, after downloading the app you have to choose the design to be printed and then plug in through the headphone jack. Finally fill the resin tank with the resin you prefer. ONO is providing multiple kinds of resins for different uses: solid, flexible, translucent, castable and clear! The $15 resin bottle is said to be able to bring out around 10 simple 3D printed objects, and the amazing thing is that unused resin can be recycled for future prints!

“We believe 3D printing should be accessible to everyone. This is why we set out to design ONO, the first ever smartphone 3D printer.” – ONO team

ONO is a rebrand of OLO, the first edition of the printer that was live on Kickstarter one year ago. More details about ONO can be found at the official website where you can sign up on its newsletter to be updated and to know when ONO will be available to buy.

4 Channel Opto-Isolated Module Using High Speed 6N137 Optocoupler

4 Channel Opto isolated board has been designed around 6N137 Opto-coupler, the 6N137 optocoupler is designed for use in high-speed digital interfacing applications that require high-voltage isolation between the input and output. Applications include line receivers, microprocessors or computer interface, digital programming of floating power supplies, motors, and other control systems.

The 6N137 high-speed optocoupler consists of a GaAsP light-emitting diode and an integrated light detector composed of a photodiode, a high-gain amplifier, and a Schottky-clamped open-collector output transistor. An input diode forward current of 5 milliamperes will switch the output transistor low, providing an on-state drive current of 13 milliamperes (eight 1.6-milliampere TTL loads).

PicoDetector : a simple metal detector

Bruno Gavand build a simple metal detector using PIC12F683. He writes:

The idea of this circuit is to hack PIC oscillator circuit, by replacing the crystal by a coil : the frequency of the oscillator then depends on presence of metal near the coil, just like in a classic metal detector.

Smart sensors track fitness activity

STMicroelectronics’ LIS2DS12 3-axis accelerometer, LSM6DSL/M 6-axis inertial module, and new LSM303AH eCompass enable always-on fitness-tracking applications to operate longer and record progress more accurately. by Susan Nordyk @ edn.com:

These smart sensors help track movement continuously with minimal impact on device battery life by performing various motion-related calculations on-chip, instead of using the main system processor.

Redefining a new state-of-the-art in microampere current-sense amplifiers

Silicon Lab’s TS1100 and TS1101 current sense amplifier’s features discussed in this app note.

Sensing and controlling supply current flow are a fundamental requirement in most all electronic systems from battery-operated, portable equipment to mobile or fixed-platform power management and dc motor control. High-side current-sense amplifiers (or “CSAs”) are useful in these applications especially where power consumption is an important design parameter. New CSA developments offer even greater benefits in allowing engineers to save power without sacrificing performance.
