Maker Faire (DIY)

Maker Faire is an event created by Make magazine (USA) to "celebrate arts, crafts, engineering, science projects and the Do-It-Yourself (DIY) mindset" I wanted to have a backup power source for my iPhone and iPad that was independent of other power sources and sustainable and renewable. The reason being that when I'm in a remote area I have an unlimited and renewable power from something that packs away small and is easily transportable.

So off to the local Jaycar I went with my design and collected the parts I would need.
1 x 5 Watt solar panel is about 10 inches or about 25 centimetres square.
1 x solar power regulator
1 x 12v rechargeable sealed battery (as small as capacity required will allow)
1 x 12 v power socket

So with soldering iron, wire and a hot glue gun I set about this little DIY project. I lay out the parts inside the back cavity of the solar panel, hot glue them in, wire it together. The battery forms a great stand and balances the panel nicely. The guy in the store, more familiar with Ohm's Law and voltage calculations than me did the maths for me and I believe:
The solar panel will charge the battery from flat in about 8 hours (if sunny).
The battery must put out at least 10 Watts to charge the iPad (iPhone needs 5 Watts)
The battery is more than sufficient to charge a flat iPad x 3 times.
Topping up the battery each day with the solar panel will keep the battery at full capacity and keep me with ample power.
Test one insert a volt meter to see if there is power? yes.
Test two connect the iPad with 12 v car connection plug and USB cable? yes
All works fine and for less than a $100 and fits in a laptop bag or similar. Hmmm maybe I could use a fuse in there somewhere???

Queensland and Back

My dog Hermione and I went on a trip to Queensland last week in the ute. Travelling from Bendigo to Mt. Tamborine we spent the two day road trip up north visiting Parkes and Forbes, the CSIRO Parkes radio telescope and iconic outback towns like Dubbo, Gilgandra, Narrabri, MoreeGoondawindi and Warwick. We spent four days on Mt. Tamborine doing maintenance on our house there and visiting my daughter and grandson. On the way back we went via Mount Lindesay Highway and cut through the back country to Tenterfield then Glen Innes, Armidale, Tamworth where we visited the big golden guitar. We then crossed  to Gunnedah before rejoining the Newell highway and heading south at Coonabarabran. Be sure to click on some of the text hyperlinks as they have some great information.
