    Altium PCB image background

    Have a look at converting a picture into DXF. That might be easier. You might be able to find a free version. A photo copier with file export features could also be used to save as a picture of PDF which could be converted. Adam

    Do you only have an image of the PCB you want to copy?

    Running servo motors with PIC and L293D H-bridge

    I think from what you just said by using the enable pin to turn the motor on and off will work I have never used this device but can't see why that won't work. So you set one input pin high and one input pin low for the direction you want and then PWM the enable pin. Adam

    Old-bie finally inspired for some DIY fun! Need a point in the right direction.

    Good luck, let us know if you need anymore help. Adam

    Old-bie finally inspired for some DIY fun! Need a point in the right direction.

    He is a circuit that might be too simple I don't know. The 4 switches connected to the AND gate are the ones you have to switch in order for the output to go high. The other two are disable switches and if any of these are switched then the output will be off. You can change how many you have if...

    Running servo motors with PIC and L293D H-bridge

    I don't know if you can put PWM through this chip. But you could try and PWM the output pin you would be putting high. Adam

    Running servo motors with PIC and L293D H-bridge

    Hello Here is the datasheet and it gives you the logic table for one driver. For your application you need to have it set up so that one of the drivers output is high and the other is low. The motor will go in one direction. If you were to reverse the outputs of the drivers the motor will...

    Do you have a circuit diagram? If you do can you post it here? Adam

    (Help) Reducing MMC capacitance for Tesla Coil

    You can connect capacitors in series to reduce the overall capacitance. But you have to be careful connecting different values of capacitance with different working voltages together. The voltage across the smaller capacitance may exceed it's rating. For example 1000 Volts across series...

    Now you are showing off :) Never used one of those, I have a calibrated finger :) Adam

    It would be good if he responded to tell us what actually he meant! Maybe he made an error, we may never know. Adam

    Depends on the meter, some will give you the K and some won't. You have to sometimes look at the scale you are using on your DMM. Adam

    (Help) Reducing MMC capacitance for Tesla Coil

    Is this a spark gap tesla coil. Are these the capacitors that get charged up and supply the energy to the primary winding? Adam
