What's a weekend without a trip to my favourite shop.....
Here are some ideas I saw this morning just....
Screaming out
to the astro community, some have been covered recently by some
threads, like the SLA battery saver....

USB Power Monitor Kit
Plug this kit inline with one USB device to display the current that is drawn at any given time.
Check the total power draw from an unpowered hub and its attached devices or what impact a
USB device has on your laptop battery life.
At the touch of a button the 4-digit LCD panel can display current, voltage or power.
It is auto-ranging and will read as low as a few microamps and up to over an amp.
It also features display flip-mode, mode memory and digital calibration.

Battery Saver Kit for Rechargeable Lithium and SLA Batteries
This tiny circuit fits in between the battery and load and cuts off the power when the battery becomes
flat to prevent the battery over-discharging and becoming damaged.
• Suits most SLA, Li-ion, Li-Po and LiFePO4 batteries between 6 to 24V
• Cut-off voltage adjustable from 5.25 to 25.5V

Knowing just when to stop at Jaycar is the hardest part....
