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 simple circuit that is a battery operated rgb color switcher that runs on a PIC10F202; When the button is pressed, the single RGB LED changes to the next color in the sequence. When the battery is installed, the unit is on, and when the battery is removed the unit is off. What I need is to have the code modified so that the uController behaves in the following manner: 1 Unit is off with battery installed 2 Button is pressed once 3 Unit turns on with last selected color illuminated 4 Successive button presses will cycle to the next color in the sequence (R->G->B->Y-C->M for example) 5 Unit will stay illuminated in the current selected color until, 6 Long press (2 seconds) will shut the unit off and save the last selected color in memory 7 Operation repeats as ...

This will be a visible infrastructure brand logo that needs to be elegant and embody newness in technology. We have found a stock logo that gets us close to the mark, but want something that has uniqueness and a bit of eye-catching appeal. We have uploaded the current stock logo design, a corporate color palette is loaded as example but we are open to suggestions from your work and flexible on color schemes we are using and the font which will be used whenever the name is placed next to the logo. Thank you for your participation and we look forward to your c...
I need a circuit diagram consisting all the necessary transistors and logic gates , to provide power to a gps, a bluetooth, a small speaker , all powered by a small rechargeable battery. I need this circuit to be less power consuming and provide more efficiency
I need to create a simple circuit diagram including specific components that allow me to detect a light or infrared, and get a 5v signal in an Arduino Uno when the light is seen. 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.

We would like to create a video with 3D animation showing how our liquid metal circuits can replace a rigid circuit board with a super stretchy material that can be embedded into a thin glove, shirt, elbow sleeve, etc. We'd like to show an exploded view of circuit/sensor with the typical "engineering diagram" aesthetic (like in the attachment) pointing out key components and capabilities. 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. I have attached ...

I want a tracking device with A9G and nuvoton microcontroller. That device will be rechargeable, I want a battery backup of 15 days, which should also be fast and chargeable. You must upload the specific thing on the firebase, latitude, longitude, battery percentage, charger pugged In or not, and device Id. On the side of the hardware, I want that device to be very cheap with good accuracy and smaller in size, I can also change my hardware if you suggest to me any other cheap and better performance.

We need a circuit that can generate impulses in the output from input source battery of 9 V. the required impulses in the output should have voltage more than 100 V during maximum load and frequency of 50 Hz.
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 need to write a TCL script (synopsys tool) to cut and remove overlaps from a given circuit design. Given Vss - ground and Vnnaon - power, the objective is to remove parts of Vss that are overlapping with Vnnaon. i have this partial working script, but it fails for some cases of multiple overlaps
I think I need a PCB designer We are in the very first step to creating a proto type. I believe the first step is to have someone design the circuit board. It's a very simple design. See attached
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.

I also need to read 8 ADC values, but it can be either through a multiplexer (I2C or standard) or some multi-channel ADC chip communicating by I2C. I need parts that are available right now and there should exist some development board with that chip that I can buy. The project goal is to find the parts and provide a circuit diagram of the solution (block diagram or full schematics). I am also open to alternate solutions which achieve the same purpose (driving LEDs and reading ADC using as few MCU pins as ...
