Mini video cams

The one thing I have not heard in the discussion on rechargable NiCad batteries is their old nemisis, memory. Having been through my share of nicads for my camcorder I know that even if you run them dead as is recomended to maintain a long memory life, they still evenntually die. And when you consider the cost of new ones, cheap alkalines don't sound so bad.

actuallly the 9v ones arent too bad, i pay 19.95 aussie dollars for the 7.2 v ones and i paid just under 30 dollars for a true 9v nicad for my multimeter
at 2.50 a pop for energisers- they would have to fail in under 12 recharge cycles to be more expensive

memory effect isnt that bad-i worked for a solar place that used nicads for elec fences-they lasted normlly 2-3 years on a daily charge/partial discharge cycle-and inside the cases often hits over 60 degrees celcius!! and had very few (in fact hardly any at all that i can remember-the sealed leadacids had a far higher failure rate)

They must have been using some really good nicads. All of the off-the-shelf ones that I ever got worked good for a while, but sooner or later they just wouldn't hold a charge. :cry: :curse:

sanyo kdrh's
expensive but not exsessively so (20 bucks australian per pair)-about twice the pric of over the counter stuff-but 4ah d cells against the normal 1.6ah d's most people buy
they are the ones used for those battery backed up exit signs that you see in public buildings

That and the ability to control the camera thru DCC chips which my supplier is currently working on. I'd love to see or develop a miniature panning device for the added ability to "look" from side to side like an engineer.

Wouldn't one of those "tortiose" (slow-mo) switch motors do this for you if hooked up to a pivot base right?

Currently getting this cam to work with the guts from a R/C car.

 

[shaygetz]

That looks perfect. What type car did it come from?

 

[Woodie]

Fabby little mechanism, Tony. But mounted in a loco, or on a flat car, how do you intent to control it? Or is the mechanism from a "radio controlled" car? (steering bits)??

Hi guys,

The mechanism shown is all Lego parts and is actuated by the R/C receiver (not shown). The original idea was to use the car parts but the Lego proved quicker and easier.
