Just about any IR remote control that's capable of outputting Philips codes can be used. This is the Select 1 from Jaycar.
Now that all the PC boards
have been built, it's time to prepare the metalwork. Hopefully, this
unit will be made available as a complete kit, in which case the metalwork will
be supplied pre-drilled.
Alternatively, if you're buying the bits separately, you will
have to drill the case yourself.
As supplied, the case comes in pieces and it's a good idea to
drill the front and rear panels before putting it together. The front and rear
panel artworks (Fig.12) and the main wiring diagram (Fig.10) show the positions
of these holes.
Starting with the front panel, you have to drill holes for
mains switch S1, the 20-LED display, the three pushbutton switches, the
acknowledge LED and the infrared receiver. The rectangular cutouts for the mains
switch and LED bargraph can be made by first drilling a series of small holes
around the inside perimeter of the cutout, then knocking out the centre piece
and filing to the correct shape.
Don't make cutout for the mains switch too big - it must be a
tight fit so that it is properly secured by its retaining tabs. The pushbutton
switch holes should be about 9mm to allow clearance for the 7.5mm diameter
