I would probably suggest a logic level MOSFET. The STP80NE03L06 is a little expensive at $2.20 but is a TO-220 package and has an RDSon of 0.006 Ohms (MOUSER...
Look at IRF "Intelligent Power Switches". http://www.irf.com/product-info/ips/ These look like FETs, but have logic drive and are fully protected against...
Greetings All, I'm looking to learn more about mapping. By this I mean I want to put some sonars, IR's, etc on my robot then put the robot in an unknown...
I would recommend you simply look at the data sheet. It has sample circuitry near the end. http://www.intersil.com/data/fn/fn2853.pdf What, precisely are you...
Hello, I am new here. I have never gone to a meeting but have an interest in robotics. I went to Western Washington University and got a BSCS in 1999. My...
yea..i think i'll try that circuitry out and hope my thingee works..it's supposed to drive a 24.V 20 A DC series motor which is fitted to the drive shaft of a ...
Those who did FIRST robotics. This year I sent data from the pre-processor to FIRST controller through the digital port. I would like to do bi-directional...
Doug: there is a wiring diagram on the IFI website under documentation regarding the debug port. Also, per the Basic Stamp manual (www.parallax.com) the SOUT...

Are you a 68hc11 user? Do you like the Botboard, or how 'bout the Handyboard? Have you used either of these and wished that the Botboard had more capabilities,...
Does anyone know where I can get some 5A (or therebouts) H-Bridge IC's in a TO-220, or TO-262 (SMT) package? I know Infineon has some (and I would love to use...
... How critical are the packages? Motorola has the MC33886 and MC33887 5.2A full H-bridge ICs but they're in a 20-lead SMT package that's 16x15mm or so. And...
That part does not look too bad. Only issue I would have with it is it maxs out at 10KHz PWM frequency. I use somewhere around 15KHz on most of my projects. ...
I'm pleased to announce that Tom Dickens has accepted the position as Encoder editor for the SRS. As you know, the Encoder is the club's online newsletter and...

I'm sure that there are Basic Stamp II programs and schematics applying to stepper motors. Types are unipolar, bipolar and variable reluctance. I'm am...

Hello Group, Does anyone have experience getting a 68HC11 to communicate (bi-directional) with the HMI program WinCC? What driver and protocol are necessary?...
Glenn, Martin Calsyn of Scarab Robotics is working on this. Check these links. Contest info: http://www.darpa.mil/grandchallenge Contact the Scarab Robotics...
Ok dudes, there are only 16 Days left to PDXBot.03 so, as you do your final tuneups for the sumo events, here are some things to think about. First of all...
Dear srs members, I am a student who is doing a project on building a robot that detects smoke, and makes a loud beeping noise when it detects it. Do any of...
Modifying a normal household smoke detector is illegal because of the radioactivity in them. You can buy smoke detectors that are designed to be embedded into...

There are 2 types of smoke detectors, one is Ionization the other is Photo-Electric. The Photo-electic type doesnt have any radioactive material and should...
... Even if it may not be illegal to modify one of the photo-electric type smoke detectors, I bet in the end you will still not have a legal smoke detector....
