[email protected] Received 30 de junio de 2011; accepted 25 de agosto de 2011 The construction of miniature LTD Stirling engine prototypes, developed with low-cost materials and simple technologies is described. The protypes follow the Ringbom motor array, without mechanical linkages to actuate the displacer piston. Different designs, sizes, materials and mechanisms components have been tested. The power piston has been replaced with a flexible diaphragm and the mechanisms linkages were constructed with piano steel wire. Power output and efficiency experimental measurements are presented for two miniature LTD Stirling engines, the MM7 model from American Stirling Company and our simplest low cost model.
