OPC stands for «Open Platform Communications» that is a set of specifications and standards for industrial telecommunication. OPC defines the transfer of real-time plant data between control devices from various manufacturers. The aim of OPC was to support a common bridge for Windows-based software applications and process control hardware. OPC was designed to minimize the quantity of duplicated effort made by hardware companies and their software partners.
The most typical OPC specification, OPC Data Access (OPC DA), is supported by Tibbo OPC Server. Any device compatible with the Tibbo AggreGate protocol can be a data source. AggreGate is a white-label IoT integration platform using up-to-date network technologies to control, configure, monitor and…Continue
The app allows you to manage traditional air conditioners that are controlled through infrared remotes. Designed for the office environment, the app relies on the ambient brightness (measured by Tibbit #28) to determine whether the aircon should be running or not. In the office setting, no lights = no people = no need for the aircon to work.
TPS-based aircon controller
Air conditioning is a consumptive business while air conditioners are big-ticket to run. In general, AC systems, older ones, in particular, do not have any real temperature feedback. You set the temperature on your remote, but alas, it has absolutely nothing to do with the actual temperature in the room. Even when it gets colder outsides, many aircons keep blasting cold air into your space. As a result, you have to…Continue
If you are interested in joining some teams consisting of makers working together from all over the world, check out and consider joining any of these projects, which are on Collaborizm, an online collaborative workspace for makers-hackers & creatives (www.collaborizm.com). Why join a project? To network with people who share you interests, globally, and to establish your online credentials to qualify you to do paid freelance gigs and to get recognized by prospective employers.
A sample of maker projects you can join, or just follow. (You can also Start a Project, or act as a Mentor if you prefer.)Continue
This is a list of circuit simulation softwares for Mac. Since most of the circuit simulators run on Windows, it may be a problem for Mac users. Here I present you 10 of the best circuit simulation tools available on Mac that allow you to design, analyse and test a circuit virtually on a computer. The programs below may provide either analog or digital simulation capabilities or both, have a schematic editor, a waveform viewer, support resistors, capacitors, diodes, etc.
1. EasyEDA :
EasyEDA is a tool based on the cloud platform which facilitates schematic drawing, spice simulation and PCB layout, so it works in almost any web browser on Mac, Linux,…Continue
Tibbo Project System (TPS) is a highly configurable, affordable, and innovative automation platform. It is ideal for home, building, warehouse, and production floor automation projects, as well as data collection, distributed control, industrial computing, and device connectivity applications.
Suppliers of traditional “control boxes” (embedded computers, PLCs, remote automation and I/O products, etc.) typically offer a wide variety of models differing in their I/O capabilities. Four serial ports and six relays. Two serial ports and eight relays. One serial port, four relays, and two sensor inputs. These lists go on and on, yet never seem to contain just the right mix of I/O functions you are looking for.
Rather than offering a large number of models, Tibbo Technology takes a different approach: Our Tibbo Project System…
With nanoscale DLD, the researchers can take a liquid sample and pass it through a silicon chip especially designed with an array of asymmetric pillars. This pillar array separates particles by size down to tens of nanometers resolution.
Today I want to make an Arduino RGB led strip project as the above picture showed. Ten LED strips can flash in different effects by using a control board.
LED strip, Arduino Nano, Dupont line and a control board.
So, how to make an Arduino RGB led strip?
Ryan made a vending machine using Arduino, 4 servos and a Nokia 5110 LCD. Cool stuff! He also shared the circuit and code. Check it out!
