Hi Anders, I have searched the internet for two days for the Murata CSB517 resonator, but I can't find a source. Nothing at Mouser, Digikey, Farnell, RS, etc. Can you tell me where did you get it? Thanks, HA5OZ

trying to get hold of a decent battery seems to be a problem. it should be light and capable of delivering 100 amps at 48 volts. i am thinking lithiu-ion or lipo,s, but this is rather expensive.  Idea,s and suggestions anyone?

Good morningthere probably is a fault:The current requirement of the circuit at (+ 5V) is far too high (> 28mA), because the voltage reference (IC3 = LT1021) with max. 10mA may be charged!The datasheet of the LTS 25-NP :-------------------------------------------------- ----------------------------------------      IC Current consumption @ VC = 5 V -> Typ.: (28 + IS2) + (VOUT / RL) mA-------------------------------------------------- ------------------------------------------So sure  > 28mAThe data sheet of the voltage reference:-------------------------------------------------- ----------------------------------The LT®1021 is a precision reference with ultralow driftand noise, extremely good long term stability and almosttotal immunity to input voltage variations. The referenceoutput wants both source and sink up to 10mA.-------------------------------------------------- --------------------------------What do you think?
