USB Ultra Infrared Receiver to remote control and power on/off the PC
Today, another interesting infrared receiver solder guide for the PC is finished. Who like to control the PC or HTPC comfortable from the sofa, can solder different IR receiver types for commercially available universal remote controls. There are some self building guides in the ocinside.de modding section for several years and today a new special infrared receiver soldering guide for the PC is published.
After the extended guide for the infrared receiver with hardware side function to remotely switch the PC ON or OFF as full USB variant with the name “USB Ultra infrared receiver” or briefly “USB Ultra IR” a new version 2.0 is now available.
The new USB Ultra infrared receiver v2.0 was – contrary to the previous version – extended by some electronic components and offers thereby new functions and some improvements. The USB Ultra IR v2.0 indicates now with a red LED the receipt of infrared signals. A green LED indicates that a power on/off signal is received which was programmed before. Furthermore a new TSOP receiver unit is used, which is more sensitive and more energy efficient. Last but not least the USB wiring was optimized, so that the operation also with all newer PCs and current motherboards should be no problem, since the USB data lines are now reduced to 3.3V instead of 5V. All other functions are explained exactly on the following pages, thus much pleasure with reading and soldering.
Where is the sense of an infrared receiver at the PC …
If you like to use the PC to watch television or S-VCD, DVD, DivX files or if you like to build a complete J-box II project with LCD display, etc. for the HiFi rack, you would also like to enjoy the comfort to remote control all applications of this PC easily from the sofa.
So the first Luxus/Lowcost infrared receiver circuit was published in July 2002 on ocinside.de and the goal was a remote controlled PC with a connection to the serial port. The next development was the USB infrared receiver guide to control the PC with a conventional remote control unit, but with an USB connection instead of using the serial port. So, there’re a few ways to manage this very comfortable – may be with the well-known Luxus IR, Lowcost IR, USB IR, or with the new USB Ultra infrared receiver which is now also offered as a complete kit in the Fanshop.
That is new at the USB Ultra infrared receiver 2.0 …
Well, but what can the USB Ultra IR receiver contrary to conventional infrared receivers ? Very simple – on the one hand it receives the signals to send it to the PC Software (like Girder, WinLIRC, etc), but on the other hand it can also compare infrared signals to power off or power on the PC. So it’s possible to remotely power on the PC (ATX Power Button, WoL, etc.), watch a film or hear some music and hardware side power off the PC. The PC can thus be completely controlled with a usual remote control unit (38 kHz RC-5) e.g. of the television, or another HiFi component and/or all universal remote control units. And since the latest version 2.0 this is additionally shown with two light emitting diodes.
Take some pretzel sticks or chips, loll on the sofa and watch TV, hear music, etc.
