So long as the visitor stretches out one`s hand and crosses the black harp of that entire body, the tone will be played . Why is not there the string to play S

He says, this is the laser harp. This laser harp lets me recall a lot of old affairs of many years` standing too, I have ever said to classmates for a long time, I can make a laser harp too, still and his bet, but because the question of time has never been finished. Has seen the laser harp of the Iranian hall, I decide to produce it, it is certainly a very simple and crude laser harp. But to friend and speech fond of DIY, it is a good intention that is made small. Install 5 3. 0V laser tubes on the wood block above, and fix on wood block below with the hot-melt adhesive. Bore the hole with the bit of 0. 8mm, and install correspondent 5 pieces of photo resistance, namely make up the fundamental base. Then, put cell box No. 5 in the appropriate place, fix with the hot-melt adhesive. Finally, according to the power schematic diagram, connect the correspondent lead wire with the socket, in order to facilitate the staging of back-end connected sum. Finally, connect with circuit board base again. I successively made two kinds of circuit of the base, the ones that adopted were these two one-chip computers of AT89C2051 and ATMEGA8 separately. Certainly, characteristic and result are different. Because the material is limited, I have only made the works of 5 strings. It is very simple for this making to weld, are all the components and parts of DIP, use the insulating mantle line according to the schematic diagram, connect and...
