The part list
This is the part list with pictures, description and a link where to find
them: I've reported Conrad's part
numbers; you can find all the needed components in this place easily and for
a low price.
1) Sub-D 9-pin serial box [Conrad 711284]; very standard component, avoid the metallized ones if you can:
2) Sub-D 9-pin female connector [Conrad 742082]:
3) TSOP 1738 IR receiver [Conrad 171077]: Many other IR rceivers are avaiable on the market, althought not always easy to find. Check lirc receivers page for a better list.
4) 4.7muF electrolitic capacitor [Conrad 460508]: electrolic capacitors are polarized, so you have to connect to grounf with the right pin; there are kinds of non-polarized capacitors and as long as they have 4.7muF capacitance they will be perfect, perhaps only a bit more expensive.
5) 5V 100mA TO-92 78L05 voltage regulator [Conrad 183024]: You must check the data sheet of your own voltage regulator; many devices have the input and output pins exchanged in position than the one I used. DON'T only rely on my pictures when you solder it. Of course you can use a device with max output of 150mA or more, but it's likely it will be a bit bigger thus more diffucult to solder inside the connector.
6) 4.7kOhm 1/10W resistor [Conrad 400335]: I used a 1/10W resistor only because it's a bit reduced in size; a normal 1/2W one will be just as good, perhaps only slightly more difficult to fit inside the connector.
7) 1N4148 universal diode [Conrad 162280]:
8) Little piece of wire:
