Dip\u00f3l lze vyrobit z c\u00edvky o v\u011bt\u0161\u00edm pr\u016fm\u011bru, nebo m\u011bd\u011bn\u00e9ho dr\u00e1tu o rozm\u011brech a vytvarovat ho o t\u011bchto rozm\u011brech : 12 x 0,5 Cm<\/p>\n

Sign\u00e1l se zachyt\u00ed v kondenz\u00e1toru C1 odka\u010f putuje do germaniov\u00e9 diody, kter\u00e1 funguje jako indika\u010dn\u00ed.<\/p>\n

T1 a T2 jsou v Darlingtonov\u011b zapojen\u00ed, kde se sign\u00e1l zes\u00edl\u00ed.<\/p>\n

P\u0159ez tranzistor T3 se sign\u00e1l d\u00e1le zes\u00edl\u00fd a pot\u00e9 je indikov\u00e1n vysocesv\u00edtivou LED DIODOU.<\/p>\n
