  1. Hi! I'm Isaac, and i'm a software developer by trade, and a beginning scientist by inclination. No formal education, because life didn't lead me down that road, but hoping to make up for it with raw unadulterated curiosity, and an absurdly voracious reading habit. I like the idea of performing actual experiments, because my working life is all virtual. My interests currently are basic electrical and biochemical - a project I am helping a friend with causes us to ask some interesting questions about the claims made by various consumer products, and devising ways to test those claims drive our quest for knowledge. Been lurking unregistered on the forum for a bit, and I'm looking forward to getting involved.
  2. I'm working on a project with some friends where we need to measure the potential electrical charge of various things. It is a fairly wide list, including hair, tapwater, the chair of the air around us, etc.... We want to know if the electrical potential is negative or positive, and ideally be able to measure magnitude. This isn't something we typically do, and we can't afford to go to a lab. This is a hobby, and half the point is to learn as we go. So we are trying to research the correct instrumentation to obtain a measurement of the potential. Obviously, a voltmeter isn't the tool for the job. From some preliminary research, it looks like we need a electrometer, but I'm finding it a little difficult to work out how to use one, and a little unsettled by how much they seem to cost. The maker in me wants to build the instrument of course.....but I accept I may just need to find one we can use. I'm looking for a little guidance, in the form of useful links, or a conversation with someone who can offer some expertise. How would you go about measuring the charge of air, or tapwater? Thanks in advance for any assistance!
