MC Easy in horizontal position

Here you see a very diletantic, but functional application of a MC_easy working in a horizontal position. As you can see, it's heated by a candle, runs at about 200 cycles a minute, and (just like his brother the MC_easy) it has a diaphragm piston. As Ihave found out lately, the pistons diameter (about 40mm) is too big for a good application, so better choose about 25mm. The walls and the inner displacer not made of polyurethan foam. It's made of balsa wood and the displacer has an old coin fixed to its left top end (some 20 gramms). To the right you may recognize a small piano wire(steel wire)(1mm diameter) coming out of the case(cylinder). This is the axis of the displacer. So the axis is fixed to that axis and outside this axis is fixed that way, that the axis acts like a torsion spring, which balance the displacer in an equilibrum-middle-position. The little tube you see on the left is just to check for air leakage, so it's closed by a piece of tape. The funny thing about this horizontal engine is, that (while being heated) it starts by the slightest seismologic event and almost can't be brought to silents (while hot).
