Elektor Android cardioscoop Deel 3
Bouw, afregeling en gebruik
Hier is het derde en laatste deel over dit bijzondere project. Op dit moment is er geen enkel commercieel apparaat verkrijgbaar dat in de buurt komt van de specificaties en mogelijkheden van deze zelfbouw-cardioscoop, ongeacht de prijs.
