The IR light therapy unit is difficult to construct if you are not an experienced constructor. If there is enough interest from all of you I could make a DIY kit available and mail it to those of you who can assemble it or pay a technician to make it up for you. The 5mm LEDS that I used are 880nm devices @ 35 mw . Maybe you could call around your local electronic suppliers and ask if they have these in stock. I could mail these out but I only have a limited supply available. BTW I am in Australia -down under.. John.
