BME 4900 FINAL REPORT 31Team 87 Budget & Timeline7 .1 BudgetAt the moment, the current budget outlook remains highly fluid. The currentproposal utilizes basic electrical circuit components that are readily available and low incost. The specifics of the current design remain a topic of discussion and, as a result, thebest estimate can be derived from the previous constructions of similar products.Malmivuo and Plonsey discuss three different electronic neuron models in their article,each using a similar quantity of circuit components. In order to construct any of theproposed models, the circuits must contain resistors, capacitors, transistors, and diodes.From the relative quantities in each of the models, it would cost roughly $20 in circuitelements per neuron population. This would give a total cost of $320 in parts.The largest expenditure for the project would be purchasing the circuit board(s)to layout the design. The current estimate places this cost at approximately $300 total,and is subject to change based on layout decisions. An enclosure for the circuitry,comprised of an aluminum skeleton with acrylic walls, would cost an additional $50.Several portions of the project will be available at no cost. Access to machines tomanufacture the enclosure is available, as is the LabVIEW software that may be used todevelop the signal analysis program. Input sources may also be available at no cost.These estimates lead to an exact total of $670. The requested budget for theproject is $700, allowing for some flexibility in the estimates provided.Table 2: The breakdown of the items purchased for the project thus far.
