I've been getting some hesitation on the truck, gonna have to troubleshoot some stuff... haven't replaced the fuel filter so I'm gonna start with that
The Ohio Random Thread... aka We Should Probably Be Working

I don't but a buddy does and he's happy with it. Only problem was the intial shipment of razors got lost but they sent him a replacement set and when the first set showed up they let him keep them.
Hope it isn't too bad for you guys and gals. We should just see some rain and wind here in the Valley but the Poconos could see an inch or so.
I am. Haven't had a single issue. Only downside is that I don't really grow much facial hair, so the razors don't wear out that quickly, so I've got a small stock pile of blades laying around. But, for the cost of one name brand refill pack, I have 4 packs of quad blades sitting here.
I passed several salt trucks on my way in to work. 91 was covered in brine Sunday night.
Let's add some physics to this thread. So who here knows a lot about circuits (Phen)? I'm trying to find to convert the stock variable resistor fuel level sensor in the RX7 to something that outputs a 0-5V signal. The best I could come up with is a voltage divider circuit with a 5V source followed by a low-pass filter to damp out oscillations to keep the gauge from reading all over the place.
Something like:
V_in
|
R1
|
|--R2--GND
|
R3
|
|--C1--GND
|
V_out
The constants are V_in (5 V) and R2 (3-110 ohm). The goal is to select R1, R3, and C1 to give the widest range of V_out while keeping current down and damping out high-frequency signals. The best I could come up with is R1 = 50 ohm, R3 = 10k ohm, and C1 = 1000 uF. If I did my math right I get V_out = .28-3.44 V, I = 90 mA max. and a 10 sec time constant. I can increase the range of V_out but dropping R1 to 20 ohm but that bumps the current to around 220 mA. Am I doing this right?

Well, I went with the 4 blade version, so I'm sure I will be in the same position as you.
I understand what you are trying to do, but I am no help. I can't remember back that far.
I haven't shaved since November of '12, just trimmers and no guard. If I get one of the new positions I'm applying for I will join the club. Seems like a good deal and my Father-in-Law recommends it but is in the same boat as Phen.
Oooooo, it's been a while since I've done anything like this. Close to 9 years to be exact (I'm getting old) but I like a good challenge. I'll play with this a little at home tonight.

its been 11 years for me, I'd have to go through my notebooks to give it a shot
I think I did everything correctly. It's not very complex but it's about as far as I got in school regarding electricity and circuits.
6 years out of school but probably closer to 8 since I've dealt with anything like this.
...and tweety finally set me off. I don't care if I sound like a pompous ass; I'm just sick of his whining, nothing-is-my-fault attitude.
Everything looks right, and you've got the right idea. And I agree that 220mA sounds like a bit much for the application. I'm just thinking of any place to do some tweaking.
LOL. Do it.
