Hi.
...So I'm leafing through the Stewart Warner catalog, looking at different gauges, whne I get the call-back from the local distributor with the cost of said gauges. I clearly cannot afford the $300 it would take for a decent spread. But, I think, I'm 6 months away from having a BS in electrical engineering. I can make a cool digital gauge no problem. With an op-amp, an AD converter, and some other sundries it really wouldn't be that much of a hassle. What I need to know, however, is what kind of resistance range a typical temprature sender has. Fuel and pressure senders, ammeters, and voltmeters aren't a big deal at all, but I can't find specs on temprature senders.
And I suppose once I got my own together, I'd be glad to assemble some for any of you guys.
I see digital gauges in JC Whitney and such going for $50. They're ripping you off. It's most likely about $15 in ICs, $5 for the digital display.
