Draft Budget

I have now made a start on the electronics budget for 2009. Remarkably, there aren't any numbers on it yet. Instead I have a near exhaustive list of predictable electronics costs. As Rob reminded, I've included programmers and prototype costs as well as measures to ensure Button (the SR Server) has enough memory to cope with the hoped increase in multimedia content.

I hope to use the 'actual costs' column from the 2008 budget as a starting point before adding on the cost of items prefixed with a '+' on the budget. The next step is to estimate the costs of the new features and get the rest of the committee to write up the remainder of the budget.

The full draft is on the Trac wiki page: Draft Budget.

A copy is here:

Things that should go into the 2009 budget:


= Draft Budget =
The following is a list of entries in the electronics and hardware budget. The prices are yet to be estimated

== Prototyping & Development ==
* Electronic
* MSP430 Programmers (x3)
* PIC Programmers (x1)
* PCB Etchant/Cladding/Equipment
* Minor Component Costs
* OLED/LCD dev costs
* Motor Speed dev costs
* Current sense dev costs
* Single run of PCBs for testing

* Mechanical
* Electro-mechanical (servos, motors, switches)
* Chassis
* Misc

== Web & IDE Costs ==
* Server
* Replacement hard disks for Button
* ...

== Kit Costs ==
Assume cost of last year plus items marked '+'

* Motor Controller Board
* + Reverse Polarity Protection
* + Current Sense hardware (detect stalling)
* + Motor Feedback (Optical Sensor)
* + Clamping on Feedback pins

* Joint IO Board
* + More Status LEDS for IO
* + Power LEDS

* Servo Board
* + Dual Power Supply Presence/Detection (cut off when 5V rail not present)
* + Power and status LEDS

* Power Board
* + Battery Indicator
* + Current sense for charge and discharge
* + Replacement to charge/run switch (contentious)
* + Reverse Polarity protection
* + USB/Live Debug Alternatives to PIC

* I2C
* + Additional I2C connects for more modules (LCD)
* + Power requirements for I2C expander?!

* USB
* + Keys
* + Hub for extra keys/hardware
* + Power to Hubs

* Battery
* + Battery and Chargers

* Connectors
* + RJ11 cables and terminals

* Radio Module
* + Xbee Modules
* + Additional modules for arena

* School Mechanical budget
* + ?

* Miscellaneous
* + Perspex enclosures/cover plates for boards (optional)

* CPU
* + Slugs (No change to xt86s)


== Competition Day Electronics ==
