1950-2010 IR Remote Control - IR Hardware

With the advent of technologies based on radio frequency, infrared control was a bit out of fashion. Projects often carry embedded radio frequency transmitters and receivers custom or bluetooth modules , often expensive and sometimes these modules are difficult to achieve. Clearly the main limitation of a system based on infrared remote control is that the participants of the media should contact "visual". Many times when a prototype that is not a limitation.

The advantages, several, simple to implement, the transmitter may be a remote control standard components are very cheap.

For example, the infrared receiver line Vishay (one of the most used brands) provide recipients with low-pass filters that minimize the influence of external interference. In most IR remote control standards (Phillips , Sony, etc) use a modulation type ASK, where the active state is actually a series of pulses that the receiver presented as a single pulse value active logic (see this link for more details here .

My suggestion is not to dismiss the idea of \u200b\u200bthe idea to control infrared may seem outmoded .

Some interesting links

To arduino, this sketch graph allows the train of pulses coming from a remote control, ie it is rather a signal analyzer and from then on continue working.

Another project complete enough that serves as a receptor for commands from a remote control standard RC Phillips 5. The project this here and you can download the sketch. Finally

draft several infrared LED driver here.

Occurs to me it might be interesting to extend the idea of \u200b\u200bintelligent LEDs, for example with infrared receivers.

Components Of A Simple Electric Motor

Open - Open Hardware

cnologia manufacturing model is one of the most interesting things in the realization of prototypes. However, adding to these objects the ability to network and interact open a new world of possibilities.
The editor of MAKE: Magazine defined some of the most important aspects of "Hardware Hacking" or programmatically modify hardware and hardware using opensource (open and free to use).

Difference Between Thermagasket And Steel Seal

SMD Soldering

SMD components for its acronym in English from components of surface mount are ideal for low profile, ie are small. Until not long ago most of the prototypes were made with PCB PCB holes. In recent years this change and the trend is to use SMD for prototypes (this was almost exclusively reserved for the industry.)

hole component

One of the advantages of using SMD components is not necessary to manufacture a printed circuit board with holes. But when soldering components technique is a little more complicated than in the components of holes. People
CoriousInventors conducted a video tutorial on how to solder SMD components.

How Far Coffee Table Away From Sofa

DALI and DMX-512 Interactive Bureau

In its initials in English Digital Addressable Lighting Interface (DALI) is a protocol for DALI Lighting Control By ballasts can be controlled and dimmers and other devices. DALI was proposed as a successor to the lighting control system known as 1-10v (that is still in use) and his time as a competitor of a system called DSI.
One of the advantages of DALI is that it is an open standard and has no owner, ie anyone can develop their own teams DALI. Is it a replacement DALI DMX-512? No, there are some important differences that suggest that it is not a replacement.
If you want a quick response in an installation of lights (eg the case of the jacket with Capri ) DALI can not get the dynamics of DMX-512. In the case of a facility with 500 DMX-512 devices each device would receive updating their status every 23ms. In the case of DALI with a communication that operates at 1200 bps to update an installation of 63 devices arrive every 1s (16ms x device.) However, one of the advantages to be found in DALI is that their slow speed of communication is easily implemented with any small microprocessor.
If we refer to finished products, OSRAM development a number of very interesting products DALI, contralateral one allows up to 64 different RGB channels in a wide power range. All this via PC, remote controls, buttons, and dimmers.
In conclusion, if we talk about interactive installations, for DMX-512 now remains the most convenient. OSRAM DALI
