[QUOTE="Trust, post: 932857, member: 181524"] This week I started with the EchoHorizonMount Usals mod . First made a 22 slotted pulswheel for the optical sensor to generate approx 38 pulses / degree AZ This EHM-100 does not have end-switches since it is supplied with a slip clutch and a blocking system . Then took the gear apart to made a longer groove since with the original length it made a arc of only 130º AZ . Machined it to a arc of 175º , at the upper side of that gearwheel removed a listel and machined a curved line for the zero switch and some space for that mico-switch . Connect it to a SG2100 diseq motor circuitbaord and a relais interface , powered by 30 volts . Already tested it and its working fine , the movement is correct with Usals according to the LAT / LON . Just have to find a proper casing for the SG2100 circuitboard and the contactor interface .[ATTACH]80065[/ATTACH] [ATTACH]80066[/ATTACH] [ATTACH]80067[/ATTACH] [ATTACH]80068[/ATTACH] [ATTACH=full]80069[/ATTACH] [/QUOTE]
