Hello, i need to filter a mix signal with a digital filter and display the filtered signal on a glcd or tft. The signal contains 50Hz base signal and its harmonics. Plus a fault signal just below 50Hz so all frequency included 50Hz must be gone but a fault signal. Output signal will be written through adc and displayed. I do have a arduino due board which has ADC and DAC moduls on board. Can you design and port it for arduino due?

I am looking for a research study analyzing current mesh network technology pertaining to a particular application. The network must be scale-able up to 1,000 nodes that transmit sensor data and receive control information. Data transmission rate is not a design driving factor. Range between each node is limited to approximately 100 m in an outdoor hillside environment. Power consumption is in fact a design driving factor and shall be minimized as each node is solar powered. Current design implementation calls for Xbee hardware. This study should include an analysis and comparison of protocols associated with the Xbee hardware such as Zigbee, Zigbee Mesh, and Digimesh. Other hardware/software suggestions are welcomed as long as they have the same footprint as the Xbee modules. The study shall conclude with a design recommendation, along with a basic implementation instructions. It is important to note that each network node communicates with an arduino, and must act as a ro...

I would like to add a 4th car garage onto my existing property in Castle Rock, CO. I have already worked with the HOA and also have had quick discussion with the Town of Castle Rock to add the addition, and all parties seem okay with the approach. I'm in need of foundation plans, structural plans, and project guidelines to add the addition. I need these plans to start permitting as well as get final approval from the HOA and town. I have the original plans from the town foundation, and structural, as well as a soils report from 2005. Also the trusses will need to be adjusted on the roof of the third car as they are failing away from the new addition. We will have to pull up the back side of the third car to redo the roof trusses and align them to add the 160 foot addition. At this time there is no need for electrical work, plumbing...just the foundation and wood structure. Outside wall is James Hardy siding, and roof is a standard asphalt shingle roof.

We need a custom interface card designed and fabricated that will accept a NGFF PCI card (such as the Intel 7265NGW) and adapt it to the proprietary 18-pin wireless card connector found in the current line of Apple MacBook Pro/Air models. Note: this is for the wireless card slot, not the SSD. The adapter card should plug into a MacBook Air wireless card slot (6+12 pin) and have an interface on it that accepts the NGFF card and routes all pins accordingly. The adapter card must be sized to fit inside the MacBook Air and allow secure attachment of the card to the adapter, and the adapter to the main board. While there are currently adapters for sale on eBay that allow using the Broadcom wireless cards found in these Apple MacBook Pro/Air models in normal Mini-PCIe slots, I need the reverse interface: accept an NGFF wireless card (as Mini-PCIe will not fit inside the MacBook) and convert it to the adapter found in the MacBook. This is for the hardware adapter only - no drivers or oth...

I am needing a charge controller for a AC coupled PV system (micro grid). My current system: I have a grid tie system connected to an off grid inverter forming a micro grid. The batteries connected to the off grid inverter are LiFePO4 batteries, which work good. However when the batteries get charged, this turns off the grid tie inverter, forcing the system to run off batteries only, until the grid tie inverter turns back on. It will continue to do this on/off cycleing. I would like to have a charge controller that will monitor battery voltage, and amps going into the battery bank, and when the batteries get near full, it would start ramping down the power output of the grid tie inverter. I don't know the best way to do this, But it may be possible to put some sort of variable resistor on the line going into the inverter from the panels..? But I want to basically regulate the power out of the grid tie inverter to charge the batteries slowly. We would need to be able to program...
