[Bill2009] has made some nice progress on a control panel for his motorcycle over at the arduino.cc forums ... all off he can monitor the data via a Bluetooth module attached to the board ...

Arduino has not included active power consumption on its data sheet but, according to the uBlox datasheet, module consumption is 286mA (Wi-Fi Tx 802.11n HT20 16.5dBm 100% duty-cycle) or 220mA ...

Portable Bluetooth speakers have joined the ... and diodes. Once the power module is found, read its data sheet to determine peak power output. The power budget for our hack would be constrained ...
