    I need assistance in setting up a new router and possibly a switch to provide internet access to multiple tenants. I currently have 1gig circuit with a /26 set of IP’s along with multiple strands of SM fiber to each tenant. What’s the best method to allocate 50-100Mbps to each tenant and to separate traffic by IP. I’ve heard Ciena would be the best hardware for this. Let me know how you would build out the network and what hardware I would need to make this happen.

I have a 5v laser for Arduino and the sensor may get only a 1% or less of the intensity of the light. don't think if there is light around, the sensor and the laser will be inside a dark space. Could be awesome if you can use LTspice XVII to make the circuit.

Then we would like to animate it “going into” a garment and convey that there is useful data now streaming out of the clothing. Perhaps after the circuit is embedded, we zoom out and see that this garment was being worn by a person and they are performing an action and it is emphasized that the material is still extremely thin and pliable.

    The project should have logic circuit is composed of different logic gates with inputs and outputs. Each of these gates have a variable number of input and output pins. Output pins can be connected to (multiple) input pins to build a larger circuit. The state of the output pins depends on the state of the input pins. The most common logic gates are: AND, OR, NOT, XOR. These gates can also be combined to make more complex logic components. Some examples include a half adder, full adder, shift register, d-flipflop to name a few. There are two special types of elementary gates: NAND(not and) and NOR(not or). They are called universal gates because they can be used to build any other gate. I need this as soon as possible.

    I have a circuit based on an attiny that power cycles an external circuit when an input is held high for 1 second or more, and then goes low again. I'm using the code linked below from github. I would like it modified so that instead of power cycling when the state change is detected, I want it to power cycle when no state change is detected. In other words, I want it to be more of a watchdog that cycles the power if it does not get pet instead of just a reboot circut that cycles power when it is told to. The rest of the code should continue to work the same i.e. don't powercycle more than once every hour. I can easily test the code here. The amount of time to wait for a "pet" should be a #define at the top of the code.
