Gosh, I wish I thought of studying this sooner.
I bought this book for general computer science information. I like it because it gives a large overview of the subject. Not just a pieces of the subject. The author is bold enough to trust the student with complex information, while also being humble enough to make sure he is teaching in an understandable manner.
Also, can't beat the price for such good information investment.

Simple easy solution
It's not as secure as screwed attachment for a gps because suction cups tend to lose vacuum, but for a couple bucks its easier than trying to figure out how to put holes in your dash without getting ugly or possibly putting screws through wires and stuff.

Fine inexpensive batteries.
2 of 2 found this helpful 5800 mAh batteries don't exist yet. Highest capacity of 18650 batteries on the market as of 2017 is around 3600 to 3800 mAh for about 10 USD per battery/cell. But these are 1USD per battery. So I would recommend a single battery like this for starters, and a cooresponding zoomable xml t6 flashlight for around 3 USD. Great for work or play and if you lose or destroy it, its 4 dollars gone. Also when they are done charging, take them off the charger if you don't get a real good one. Cheap chargers can overcharge and kill or even detonate Li-ion batteries, especially unprotected cells like these.
I don't recommend these for headlamps. They run out quick on the brighter lamps and are frustrating. I recommend tenergy 18650 for that. Tenergy cells last for at least an hour, but they are quite a bit more money.
