    Power Supply and Multimeter at 3,3 Ampere...

    The powersupply itselves is done so far. I can change the voltage from something about 0 up to 30 Volt and the current LED seems to work fine! Now I have to grill some AVRs to get the multimeter working  ;D and build a small case... Want to see some pictures? Here you go:

    It's me again! I nearly have done the powersupply, only the transformer is not available  :-\ Although here are the first pictures including a modified layout:

    3-Axis Stepper Controller

    exactly i too had hard time in finding those 5804 chip. either no availability or too costly for a small CNC project.so i moved for pic based stepper controller(linistepper)

    I just finished the the layout and the schematic diagramm (Eagle files) !! After buying all reqired parts I will post some fotos and a link to the german HowTo  ;D

    Power Supply and Multimeter at 3,3 Ampere...

    Well, the problem is, that i cannot find exactly the same resistor... I only found 9 Watt resistors from 0,33 to 0,47 Ohm, but it would be too small, wouldn't it? And don't worry about the cooling stuff, I have some old CPU cooler. I wanted to use a fan anyway  ::)

    Power Supply and Multimeter at 3,3 Ampere...

    Once again a big thanks for your help!! After searching a while on my german shop's site I decided to choose these parts: and some heatsinks I already bought. Are the 10.000 uF of C1 enough? It's the biggest on I found... BTW: I would really like to make a HowTo of my version of the power...

    Power Supply and Multimeter at 3,3 Ampere...

    Thanks for your reply! I decided to use the KBU 4J. Are there any other parts, which would also work on there limit, if I have a max current output of 3.3 A on the transformer?

    First of all, I want to use this transformer. Yes, I'm from Germany  ;) Input Voltage: 230 V Output Voltage: 2x 12 VAC Output Current: 2x 3,33 A Power: 80 VA Do you have any partnumber for suitable diodes? I don't really want the 1N5402 to operate on there limit, I would realy like some buffer...

    I ust worry about D1, D2, D3 and D4 because they are specified for only 3.0 A but there will be an possible input current of 3.3 A  ???

    Power Supply and Multimeter at 3,3 Ampere...

    Just a short question: What do I have to change, if i want use an 24 VAC 3,3 A transformer for the "0-30 VDC STABILIZED POWER SUPPLY" and the "Voltmeter + Ammeter LCD panel"?

    Digital motorcyle gauges

    well why i liked above ckt is bcz of its simplicity. it can remember the last distance travelled. and ofcourse i need speed of the bike.i may face problem while attaching the sensor moudule on wheel.

    Digital motorcyle gauges

    then insted of using char. display LCD u shld go for graphic display LCD so ru gona make this ckt?or do u have any other speedometer schematic.
