Hi John,

I read your article on designing with thermistors and have a question concerning adding a resistor in parallel to achieve desired resistance at 25C.  If I were to use an off-the-shelf 1k ohm thermistor and wanted to achieve approx. 80 ohms @ 25C, I could use a 82 ohm resistor in parallel correct?  Or would I need to use the resistance equation with know thermistor resistance/temp points?

Good day,

I picked interest on you after going through your short profile and demand it necessary to write you immediately. I have something very vital to disclose to you, but I found it difficult to express myself here, since it's a public site.Could you please get back to me on ( for the full details.

Have a nice day.

if you'd think this is a good concept, i'm all ears for your suggestion.


you are driving at 35mph or more, a tailgate driver is approaching less than 15 ft, a pair of red lights (additional visible small lights) mounted in the rear at the eye level flash on to alert the tailgate driver he/she is coming too fast and too close to your vehicle. additional red lights and audio speaker mounted on the dashboard alerting that you are being tailgated. this concept works really well for tailgate drivers as well as for drivers being tailgated. it's the visual and audio warning help prevent tailgaters resulting in serious accident.

though auto makers are coming out cars with the Accident Avoidance System, this simple device costs alot less and can be installed on any type of vehicle.

thanks for the suggestion. i got a working prototype and it's working very well. the next step is marketing it. my marketing model is an aftermarket product sold in automotive stores, online or anywhere there's traffic. i'm a one-man operation, so i don't have the resources or any other means to take it to the next level, mass produce, that is. i'm not an engineer either. i'm an enthusiast who thinks this concept works well in preventing rear end accidents; especially, small vehicles tailing larger ones, such as van, truck, suv, and big rigs.
i'd love to gather a group of engineers/investors to bring this concept into mass production. if you have any idea, i'm all ears. thanks.

I attempted to add an Inventor-Entrepreneur forum but received an eerror message. I sent a trouble report.
