    Nest Protect gen 2 POE

    Hey all i am looking for some advice in how to go about my project with a Nest Protect gen 2. In my home i have ran cat6 wire to all 3 locations that require a smoke detector. These cat6 cables are connected to a POE switch for powering the Nest Protect. The version i picked up for the Nest...

    Arduino reading double-din radio volume rotary dial knob

    Alright another question - since this is an infinite turn in either direction how would i determine, say for music volume, if its back at 0 or if its all the way up?

    Arduino reading double-din radio volume rotary dial knob

    Hey all I bought a Chinese double din radio in order to modify it to my liking. The main reason why i went with this one is that it had a few buttons and turn knobs on the front and i wanted to use an Arduino in order to "read" this inputs in order to do stuff within my software program...

    Multiplex IC 5 inputs and 5 outputs custom?

    I'm not 100% sure yet but a guess would be at least 6.

    Multiplex IC 5 inputs and 5 outputs custom?

    What I am looking to accomplish is taking this layout: and connecting those pogo pins to the multiplex/demultiplexer/crossbar switch/cross point switch in order to allow for different pcb models that have different pin layouts in order to flash firmware to them using the FTDI. Hopefully...

    Multiplex IC 5 inputs and 5 outputs custom?

    Would the Crosspoint switch work even if its Analog for the RX/TX? The RX/TX/5v/3.3v/grd will be coming into the IC via a FTDI ft232r chip. Also most of these I've seen are either for Audio/Video or LVDS signals?

    Multiplex IC 5 inputs and 5 outputs custom?

    I will need to be able to use all of the inputs and outputs at the same time. Example: Input 1 --> Output 4 (5v) Input 2 --> Output 1 (RX) Input 3 --> Output 5 (TX) Input 4 --> Output 2 (3.3v) Input 5 --> Output 3 (gnd)

    Multiplex IC 5 inputs and 5 outputs custom?

    Hey all I am wanting to know if there is an IC that allows me to do the following: - Have 5 inputs - Have 5 outputs - Ability to take any input # and direct it to any output # The latter bullet there is the main goal. So in the image example above say that I needed the following...

    wire gauge for iPad mini 2 soldering

    Hey all I have a simple question that I haven’t been able to find the answer to. What gauge wire would I need to purchase in order to solder a wire to some places on an iPad mini? The area looks like this: Originally I was thinking that 30ga would befine but I’m not sure.

    4n25/35 optocoupler detect led on/off

    Hey all i am just wondering if my drawing below is correct in order to have an arduino detect an on or off led on another board using a optocoupler? My thoughts of the above drawing is that when the led is on it will trigger the relay inside and send 5v to the arduino digital pin to read. 0v...

    24-30pin connector for digital picture frame

    The reason for just wanting one single cable going to the DPF is because i want to make the actual frame as slim as i can. Nobody likes a 1"+ off the wall sticking out. Each board will connect to a separate panel. So i will have 3 boards in total. The other way around is that i can house all...

    24-30pin connector for digital picture frame

    Hey all I have 3 27" lcd panels that I will be making digital picture frames out of and I am looking for advice on what i can use in order to use only 1 cable going to the digital picture frame since it will be on the wall. The less wires the better. Currently I will be purchasing the lcd...

    AMS1117-3.3 from 5VDC show 0.09vdc

    Alright this is what I have to work with: 2 x .1uF 100v Stack Metal Film 2 x 1N4148TA 100v 0.2A 2 x 35v 470uF 2 x 25v 47uF 20% 2 x 35v 220uF 2 x 10v 100uF 20% 2 x 1.0uF 50v 20% Any of these work to step it down or use for the capacitors on the AMS1117?

    AMS1117-3.3 from 5VDC show 0.09vdc

    i dont have any capacitor on hand so is there any combine resistors I could you to get what i need for the input? Does the fixed version need anything on the output?

    AMS1117-3.3 from 5VDC show 0.09vdc

    Hey all I am having an issue using this AMS1117-3.3 SMD: According to its documents it says its either a fixed or adjustable version? So I hook it up as I see in the documents: The left pin (1) being Ground. The middle pin (2) being the 3.3vdc output. The right pin (3) being the 5vdc...
