    Digital Walking Cane

    Weird, I didn't get a notification for this reply.. email's messed up again I've programmed for both Particle and Arduino, and I can say that no, you won't get stuck :) The Particle and Arduino both use pretty much the same methods/functions, syntax, and ways of going about doing stuff. A...

    Your welcome! I wish I had this kind of help when I came back to electronics after several years, so I'm happy to help! :)

    Digital Walking Cane

    The Photon is only .8" wide, so it should be able to fit snugly, it not another .5" wouldn't hurt ;) I'm not sure what's available to temperature sensors, I haven't worked with them before, but the two options are the Thermister (resistance-changing resistor based on the temperature), and a...

    Yup! Your on the right track :) The Photon is really easy to get the hang of, I got one for Christmas and I was using it in about 30 minutes

    Digital Walking Cane

    This seems like a neat idea :) For the microcontroller I would probably either go with a Particle Photon which has WiFi, or an Arduino Nano with a bluetooth module, both of which are pretty small boards

    Looking for a 12v 3.5+A MOSFET

    Ah, I see now :) No, I have never seen it :P

    Looking for a 12v 3.5+A MOSFET

    I've found the PSMN022-30PL, which I'm probably going to go with if no one can recommend anything better, or an SMD alternative that can be hand-soldered. It can switch up to 30v at 30A, it's a standard TO220 package and it's cost-friendly at only 0.88 per unit, $11.64 altogether...

    Looking for a 12v 3.5+A MOSFET

    I just came across the RSD100N10TL from ROHM, which is an small SMD mosfet, that supports 100v at 10A, but the price is a bit high ($24.96 + $8 shipping), ideally I'd like one that's around $1 per mosfet, and I'm afraid the PCB wouldn't be able to dissipate the heat generated...

    Motion Detection

    You may want to go with a PID motion sensor off Ebay, their pretty inexpensive, they usually they have a potentiometer for adjusting the sensitivity and range, and a relay connected to a screw terminal that is closed when the motion is detected. The other thing that is commonly used for...

    Looking for a 12v 3.5+A MOSFET

    I'm working on a control system for RGB LED strips. I have the main PWM controller (using a TLC TLC5940) board in the fab, and now that I finally know the specs for the LED strips, I'm starting work on the power board with the mosfets for changing the 5V PWM into 12V. For reference, these are...

    Need help finding a microprocessor

    Thanks so much! I don't know why I didn't think of looking to see if there was an Arduino that had what I wanted :P

    Need help finding a microprocessor

    I've ordered 10 meters of non-addressable 5050 12v RGB strips to do some custom lighting in my office/bedroom. I want to design my own controller board that will allow me to drive the individual strips off of an app on my computer. I've got everything to do with the app and communication to...

    Need help figuring out yet another component

    Ok, thanks! I'm still pretty new to this stuff, so I'm still learning all the symbols Aww, doesn't look like my meter can read them, thats cool though

    Need help figuring out yet another component

    So it is an inductor then?

    Need help figuring out yet another component

    I'm putting the schematic from here together in eagle for the LM25965, and it has a component symbol that I'm having trouble finding what it is The component is the one at the top right, with the squiggly line, that's labeled "L1 - 150uH" I think It's an inductor, but I wasn't able to find...

    What component is this?

    Thanks! I'm just starting to learn electronics, so I really appreciate the help :)

    What component is this?

    I'm putting together this schematic, from this project, to use in Eagle for a project of mine: I've almost finished putting it together, except for the parts that say "4k7" and "1k5". I'm assuming that since a rectangle is used to represent a resistor in other parts, that those are resistors...

    Need help finding a USB hub schematic

    I've found what I needed, I ripped apart a USB hub I had, and found it used a "FE1.1s" chip for each set of 4 ports. Then I was able to search for the chip and find some schematics

    Need help finding a USB hub schematic

    Yeah I found that, but it's a bit vague about the "USB hub logic" part
