Have VB Create a .csv file

I built a data logger that I want to be able to download to a PC. Does anyone know the best way to get VB to create a .csv file based on data that comes in through the serial port (using MSComm Control)?<p>I have been able to get it into a file but without any separators.

Re: 220 Volt Appliance to 110V

Thanks a lot for the help. There were just a few wires that needed to be switched on the transformers. <p>I got one working perfect. The transformer on the other one was so old and dry rotted that all of the leads crumbled off of it when I touched it so I might just trash it.<p>Thanks again,<p>-Jeff

220 Volt Appliance to 110V

Does anyone know an easy way to change an appliance that requires 220V AC so that it can run properly off of 110? I have some old HP power supplies that I would like to do this to.

Re: Remote control reciever

Have you tried power transistors? These will have very low current draw. Also they come in all different values so finding one capable of handling 2 amps should not be a problem.

Solid State A/B Switch (audio)

I'm wondering if anyone knows of a perfectly clean way to build a solid state A/B switch for a car audio system. Currently I'm using relays and a pic to do this job. The relays are big and sometimes cause a slight pop in the speakers when switched. My main concern with the solid state electronics is...
