Is there a way to convert an ACE Tachmaster II to a digital readout? I can solder and read a basic schematic, but thats about it> Thanks for any help.

RPM=0
RPMSamp=0
'** RPM **
'60 ms Sample time yields direct RPM readout in 1000's
'Comments start with real RPM of 143,578 and RPMNumSamps=3
Count tachPin, 60 * RPMNumSamps, RPMSamp 'RPMSamp = 430
RPMSamp = RPMSamp * 10 'RPMSamp = 4300
RPM = RPMSamp / (RPMNumSamps * 10) 'RPM = 143
IF NOT RPMNoDecimal Then 'Calculate the tenths if RPMNoDecimal = 0
RPML = RPMSamp // (RPMNumSamps * 10) 'RPML = 10
RPML = RPML / RPMNumSamps 'RPML = 3
EndIF :)

Hi,B72

as the Tachmaster is an analogic instrument ... the best would be to use a commercial 3 1/2digit - batt powered ( for floating ...) -voltmeter, connected as a mA meter, instead of the old galva.

JetPr :D :D :D ... you'll always make us laugh !!!

Thansk for the replies. I couldn't take it any longer so I sold the ace and bought a digital. B72

Hi, B72

I do agree ... that the best it was to be done ( morover, a Digital price, now, is ridiculous ... ). but, one can love some oldies !!!
