Using Software to Boost Business Efficiency: A Short Guide

There is no doubt that a new and innovative age of software automation — driven partly by AI and machine learning breakthroughs — is already upon us. In the 2010s, developments in business process software created a number of solutions to drive efficiency in business. It seems certain that efficiency will remain an important priority of software and automation in the 2020s, too. As such, here are some tips to keep your company abreast of all the most important developments in business-boosting software. These will help your company improve its efficiency and ultimately boost its profits in the long term. Continue reading

Just How Much Is Your Old Phone Worth?

recycling_phone

So you’ve treated yourself to a new model of phone, and now your old phone is just sitting around in a drawer at home, unused. Why not sell it to make some money for yourself, rather than letting it gather dust and cobwebs? There’s definitely a market for used iPhones and smartphones right now, especially with people upgrading their model every year or two and being left with a perfectly functional phone that’s just not being used. But you’re probably wondering, just how much money is your old phone worth? Should you sell it on, and how much money could you really get for your old phone? Whether you’re thinking of selling your old Apple, Blackberry, Samsung Galaxy or Huawei phone, here’s your complete guide to working out the value of your old used phone.   Your Old Phone Could Bring in a Nice Sum of Money You may not know it, but your old phone could bring you a decent amount of money if you decide to sell it on. A bit of extra cash always sounds good! How… Continue reading

5 AVR Microcontroller Projects for Students

Engineering students who are keen to learn and explore more often search for the projects which are easy to try and which can give them some confidence in what they learned so far. For the students of technology here we are enlisting almost fifteen AVR Projects which they can try to build. It will be helpful for their studies and research as well. But keep in mind that here we will give only a brief introduction and explanation of the project. We won’t provide you with any diagram or other technical information. This article is just for reference purpose only. Temperature Controlled Motor This temperature-controlled motor application can be seen in our daily use appliances like Air Conditioner, Refrigerator, CPU Fan and many more. This simple project works on the simple principle that if the temperature is greater than a certain value defined by the user, the motor will turn on. You can think about more application for this Microcontroller project like you can keep the living room temperature at a certain limit. As the temperature goes up, fan or… Continue reading

Simplest Attiny85 based watch

We are used to see different kinds of DIY watches. Some of them try to stuff lots of functionality, other make fancy time telling format or simply mimic smart watches. But why not build a watch that only tells time in a simple manner. This Attiny85 watch is what it does. Schematic is very simple and straight forward – Attiny85 microcontroller, 12 LEDs, push button, three resistors and coin cell battery. Such simplicity allows building small watch shaped PCB where all components are fit to look nice and light. Since microcontroller comes with only 5 I/O pins (excluding reset), LEDs are connected using smart Charlieplexing method that allows saving pins for simple I/O tasks. The only shortcoming of this watch that time is counted using microcontrollers internal clock which may not be very accurate. As author states, clock is capable of keeping time within two minutes over 24 hour period. There are ways of calibrating internal clock source by manipulating internal registers, but in the end there is no point, as oscillator is dependent on many external effects like temperature,… Continue reading

Attiny10 miniature breakout board

If you want your microcontroller to fit in tight spaces you need to use very small packages. One optin is to choose Atmel Attiny10 microcontroller which is really tiny. It has 6 pins, where 4 of them are I/O. It features 1KB of Flash, 32B of RAM and can be clocked at 12MHz. Power supply can vary between 1.8V to 5.5V. They come in two types of packages – SOT-23 and UDFN. Dan Watson have built a mini breakout board for Attiny10 mincrocontroller. He wanted it to be really small and came out with size similar to 5mm LED head. To reduce size, he used small pitch (0.05”) header pins that doesn’t fit to breadboard. So additionally he made a special adapter board to be able to program it with standard ISP programmer. Continue reading

Placing watch on the ring

Building a wrist watch is quite a challenge, but when we want to squeeze electronics in to ring then real fun begins. It becomes even harder when using building blocks that are meant for prototyping. Anyway take a look at following instructable, where 陳亮 have put decent looking ring watch. He had to squeeze Attiny85 microcontroller which comes in SOIC package. It’s been soldered on small prototyping PCB. Another large part of it is display. It’s 64×32 OLED display module with SSD1306 controller on board. Display is a biggest part of all and determines the ring width. Ring watch also carries s CR1220 battery with expectancy to last at least for half an year. Three push buttons gives ability to change settings. Time is counted internally and here helps Paul Stoffregen time function arduino library. Continue reading
