The Projects:

 

The Lino Project with Arduino Mega 2560: Interrupts and Motors by

 

This project is an homage to   friend Lino Zangirolami from Italy, a 71 y.o. crazy guy with an incredible experience in mechanics, CAD Machining and design: one of the most creative makers he will ever know.

He is involved in the jewelry stones cutting business and some months before this was posted he talked about a series of problems he was always having with control of a special kind of semi-automated CNC, the cabbing machines, used in his job. These machines can replicate a 3D model, just like a pantograph can do with 3D designs. The problem is that the motion of these devices is almost primitive and imprecise. Without the need for a complex explanation, there is a rotation motion actuated by a big DC motor that gives some imprecisions to the machine making the entire device very heavy.

Remote Temperature Sender by

 

This project was initially part of the Forget Me Not Design Challenge.

Eric did some excellent work using RFM69 transceivers.

He also shared the work and   was able to make use of it for part of his own Application.

 

You can follow his work here.

Wireless Sensor Node and Gateway Design Details

 

At a later date   was asked about doing an article for TheShed magazine.

The publisher wanted a remote display of the glasshouse temperature, and it seemed that could adapt this to show the concept.

 

Many of the readers wouldn't have the required OpenHAB display we were using in the Design Challenge, and therefore a receiver and some form of display was necessary.

Celebrating Arduino with a Torch Relay!  by

 

Such wonderful occasions, like the Olympics, just have to include a torch relay.

 

Now, being that this is a techy forum, and that we're talking about Arduino here, this particular torch relay involves passing the blink of an LED amongst boards.

 

This project is designed to show how far Arduino has come since the original Arduino environment was started in 2003. It also is intended to show how easily a sketch can be ported across various different boards.

 

While this project only scratches the surface of what Arduino (and compatible) boards are available (and are capable of), it shows how much of an impact Arduino has had on in particular, which may also be representative of other hobbyist type users around the world. It didn't cost a fortune to build up this collection of various Arduino based boards, partly because of the availability of clones in this open source environment.

Arduino and ESP-01 based irrigation system by

 

The purpose of this project is to create an automated irrigation system based on an Arduino Uno and ESP-01. It will need to automatically detect when irrigation is required and if there is water in the reservoir so that irrigation can initiated. If the reservoir is empty, then an e-mail must be sent to inform of this so that the situation can be remedied. If irrigation is required and water is available (and all the safety requirements are met), then irrigation should be initiated.

 

The system includes a soil hygrometer sensor for detecting the dryness of the soil, a water reservoir (a bucket of water), a water level switch for detecting if the water reservoir is empty, a peristaltic water pump used to irrigate the soil, and an OLED graphical display and a rotary encoder which are used to adjust humidity thresholds at which irrigation should be started and stopped.

 

As mentioned earlier, the system also includes a set of safety requirements which have to be met.

Robot balances and translates on a ball using Arduino. by

 

A robot that can balance and translate on a spherical ball is developed. Its primary purpose is to focus on the high mobility in a narrow space. It can be applied in many applications such as home automation, indoor services, ...

 

The complicated ball robot system with large size is implemented by using two Arduino Due boards.

 

The robot collects data from a 9DOF Xsens IMU which possess the high accuracy of measurements. By using this device we can obtain the lean angles of the robot. Two Arduino boards and its shield is used to sense the signal from the sensor and generate control pulses for 200W AC Servo Motors. The translation and balancing of the robot are governed by the combination motions of the three omnidirectional wheels on a spherical ball.

Edge Lit signs by

 

This project was a derivation of 's Illuminated Beer Tap Beer Tap

 

The basis for this article came from a visit to a night market where one of the vendors was selling small edge lit signs.

While these aren’t new, the ones he showed could change color with a touch of your finger.

 

Edge Lighting is based on sending light into the edge of Glass or Acrylic where it bounces around until it escapes.

You may have viewed the EXIT signs which hang from the roof and are 6-8mm thick.

 

Some restaurants and shops have a plain edge lit panel which they write specials or other enticing offers in bold colors.

Indicator Tester by

 

Some time back   blogged about things going wrong

What went wrong

 

He had made some electronic Brake/Indicator units, that took seperate Brake and Indicator signals and mixed them to drive LED tailights.

 

In NZ and some other countries the indicator is a seperate 21w lamp and an amber colored lens.

Older American cars simply use the same lamp as the brake light and flash it when the indicators are operated.

 

There are several ways to do it, and GM tended to use extra parts in the column switch (which fail over time or when overloaded)

 

  made several of these in a couple of different configurations, and set number 3 was offered to a local Hotrodder.

He struggled with the wiring and then hit the issue with combining tail/brake and indicator into a twin filament lamp.

His budget didn't extend to an automotive electrician and relays or whatever they would suggest (no-one else offered a solution).

Fruit Ninja (Simplified) 80 * 80 by

 

As you can see the canvas is just 400 pixels; this limitation forced to leave out some things that are unnecessary. So first step, he listed out the must-have features for this game.

 

First, the trail after a hand movement like a blade when cutting something. Second, fruit (why not ?). Lastly, the bomb. he also managed to integrate the split fruit particle when being cut. The challenge of this project was to pick the color for each of them.

 

 

3D Filament Dispenser by

 

When the filament roll is half used or more its spirals become smaller and in some environmental conditions, the filament tends to break too frequently.

Long print jobs become less reliable; for example, you can't leave the printer working alone for an entire night without controlling it. Thus the idea to make a controlled filament feeder figured a precise series of issues to solve.

 

  • Make the automated engine almost simple and easy to reproduce
  • Reduce as much as possible the number of non-3D printable components to make it
  • Reduce as much as possible the stress applied to the extruder while printing
  • Use a low cost and easy to program micro controller board
  • Use the weight load sensor to keep under control che filament consumption and filament feeding
  • Manage the environmental noise interfering with the filament weight measures

 

Also using a single 3D printer we frequently manage more filament rolls (different colors) not all at the same level depending on the print job we are doing. Using an Arduino and the TLE94112EL shield motor controller may result in the most reliable and cheaper solution: the board can control up to 6 different brushed motors with simple commands. This Infineon board has its own half bridge motor controller including three different frequencies PWM channels: 80, 100 and 200 Hz. In practice, this means running motors sending commands from Arduino keeping the MCU free to other tasks while motors are running.

Travelling Dolly by

 

  had a conversation with one of the guys at work who also dabbles in photography.

He asked if he'd seen any of the moving shots that were not a video, but a series of still shots but they moved the camera.

 

Intrigued,   started looking and discovered that there was a large number of interesting builds.

Some were extremely amateur in his opinion and there were comments about the need to tweak it each time it got used.

 

Many of the drive systems worked only in ideal conditions, and couldn't do vertical or steep movement.

HomeMinder by

 

This project was a suggestion from the publisher of TheShed magazine  https://www.theshedmag.co.nz

He was using those mechanical timers to turn on lights while he was away, and got sick of them failing.

 

They'd been keen to find a solution to switch mains that was safe for readers.

As we've seen here Mains and Safety aren't always sitting together in some posts, and element14 has supported our efforts to rectify this.

  looked at the wireless outlets that were available through a NZ and Australian retailer, and were affordable.
