Description: Thermistor to voltage adapter circuit.
I have a digital temperature control I need an adapter interface designed for. The control receives 0-10 volts and I wish the sensor to be a Thermistor. I would like the system design with a simple op amp and it will need a tuning trim. The control is eight channel but single unit design for each channel is fine whichever is easiest. I have seen some circuit designs on the Internet but most of them have a trigger control for a relay and I do need a continuous rise or fall. Drop me a note with questions and or a quote
Thanks

Thermistor - op amp - ouput 0-10volts - input digital temperature control

Project
Category: Engineering / Architecture
Subcategory: Electrical Engineering
Description: I am a professional gamer who competes on the Xbox 360.  Me and my team attend tournaments all over the world for thousands of dollars in prizes.

The project I've been working on is developing a competitive gaming controller designed for the Xbox 360.  I've done a lot of initial research but have hit a few snags which I was hoping you could help on, then was also looking to have the prototype manufactured and set to a point where I can mass-manufacture it.

Parts:

Switches (For Face Buttons, Possibly Triggers)

I looked into it, these are what is used in competition grade keyboards at the moment and they seem like they would serve the purpose for a controller as well.  Unsure as to whether putting these into a controller, which is much smaller than a keyboard, is feasible though.

Triggers

I want to have a setup for the triggers where they can be removed and replaced, similar to the triggers on a paintball gun.  Ideally this would be able to make an effect of having a hairtrigger (where just a tiny amount of force is enough to hit the switch, firing the gun in game) or to allow for a longer trigger pull if that is what the player prefers.  If this isn't possible/feasible then the trigger needs to default be set up as a hair-trigger.  In the current Xbox 360 controller a potentiometer is used which goes from 0 to 100, at which point the gun fires.  Ideally I'd like to replace this with a switch, so that the response time is much quicker.

Joystick

Here is the part which has been used in every controller since the Sony Playstation:

The cap on top has changed, but the joystick part has remained the same.  It is just 2 potentiometers which send directions back to the console.  This is where I've had a lot of issues as to how the part can be improved while keeping costs down.  The stick isn't bad at all but it doesn't move as smoothly as it needs to for competitive play, and there is a large "Dead Zone" in the center of the controller before the controller sends readings, making it hard to make finesse adjustments.

Plastic/Form Factor

I'm not sure how to go about this part of the process, and research didn't turn up much.  I'd like it to closely resemble the form factor of the current Xbox 360 controller.

=========================

I'm admittedly new to all this and while I have a ton of knowledge on the end product and its use competitively, I really don't know much about the manufacturing/engineering aspects of it all.  I've researched it enough so that I'm not a complete idiot on the subject, but I need to know more and connect with people who can help make my vision a reality.

Date and budget are flexible.
