The requirement was to add a digital readout to an otherwise manually bend roller machine so that we could accurately monitor the amount of material fed into the machine. The readout should be simple to use, require no setup other than initial calibration and above all be reliable. First a little background on me, I`m a Mechanical design engineer

by training but I`ve always had a `thing` for software and electronics. I`ve dabbled in electronics at a hobby level for a number of years so as you can see I am by no means an electronics or software expert. I thought I would document my use of an Arduino (see here for the Arduino software and hardware ) in an industrial production environment as I felt it demonstrated what it is possible to achieve with limited experience. Traditionally this sort of project would have been prohibitively expensive and would require both electronics hardware and software experience but by using an Arduino Mega and some off the shelf components it is possible to produce a usable solution to the problem without excessive cost. The main unit is mains powered via a Traco TXL SMPSU this feeds a 12V DC to a small matrix board containing a 5V regulator circuit to power the Arduino and LCD. The encoder was powered from the 12V DC. The encoder is a Hewlett Packard panel mount optical encoder with 360ppr (pulse per rev) and is available from RS Components (205-6853). The documentation is the usual concise HP offering and gives all the relevant details of the device. The display I selected was a 20 x 4 Black/Green LCD with a selectable Serial / I2C interface. This was chosen to simplify the interfacing with the Arduino (only 4 wires required) The workpiece is setup in the rollers and the display is zeroed using the Reset button, the workpiece is fed...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
