request, 12vcd (automotive) to 12 vac power supply

Why?  So I can run a pile of 'pro' audio equipment on a parade float without resorting to a generator or an off the shelf 120vac (barely) inverter. The equipment I'm talking about is a pair of 4 channel wireless mike receivers (8 mikes total) and a 10 channel mixer.  Other input comes from an MP3 player or CD player.  We also have an AM/FM/HD radio on board for those long waits in parade linup.  The power amp is an automotive (12vdc) unit, 4 x 1000 watts.  Main power is a pair of deep-cycle NAPA (optima clone) spiral cell batteries topped-off from the tow vehicle via a charge isolator.  There is also an 35watt solar panel (again, for those long lineups) run through the charge isolator.  The solar panel maintains the batteries while the float is parked or in storage. Cracking open the gear we have, every single one of them uses a 10:1 step down transformer to drop 120 vac line to 12vac before dumping it into the mainboard. It looks like 12vac @ 3 amps will do it for the wireless mike receivers and mixer, but why not shoot for 5 amps to be safe? Ideally, there would be some serious filtering and regulation/protection on the output. In a Perfect & Ideal world, there would be multiple 12vac outputs each capable of 2 or 3 amps and isolated from each other. Too much for a request?  You never know if you don't ask. And, in advance, many thanks!

Japanese Glass Float

I'm not quite sure how big it is exactly, but it's definitely bigger than a volleyball. Anyway I have absolutely no idea what to make for it.

Would this floating idea be plausable?

Basically, I was thinking in my sleep as I usually do. I thought about how less dense things float on top of more dense things. And this got me thinking towards this: Are there any gases that are more dense than the human body? If so, we could float on this particular gas (with gas masks or oxygen tanks of course). This also led me to think about: Are there any liquids which are lighter than air? We could have a swimming pool of sorts that floats on the ceiling. All we would need is the right chemical. Any scientists out there? (I know it is unlikely as states of matter generally mean that in terms of density, Solid>liquid>gas.

Any ideas on how to build a floating vegetable garden for the cottage?

I'd really like to grow veggies at the cottage, but our wee little island is covered with trees and hence, too shady. I don't want to clear any trees so I was thinking a floating vegetable garden would be great! Here are some of my ideas: -some sort of floating dock-like structure holding/attached to garden beds -some kind of earth-box style planters -some sort of string/osmosis type system that could suck water out of the lake to keep the soil moist (okay, I know this is really pushing it. Maybe a pump would be more realistic). -NOT hydroponics: I'd like to grow veggies in regular soil, just out floating on the water instead of on the land!

Tired of dumping dehumidifier... Float switch, submersible pump, and a timer?

I have a small dehumidifier with a removable tank that has to be emptied far too often.   It has an integrated float switch in the tank that shuts down once full, but if you neglect to dump it, the basement gets way too muggy. I would like to put in a submersible pump (like this) that is activated by a simple mechanical float switch.  Once activated, I only want the pump to run for a set amount of time, in order to keep the pump from pumping all the water out and running the pump dry.  I thought about this timer, which has a minimum interval of one minute.  One to two minutes of pumping would be about right for the tank size, depending on the pump flow rate and where the float switch was set to initiate the pump. I had originally looked at a Kerick Valve float switch, but this will only let enough water drain out to lower the float and close the valve.  This will essentially just trickle out. Any ideas on this? I don't want to drill a hole in the tank and just run a drain tube... though I considered it.  Part of the reason is that I wanted to avoid just letting it trickle out.  And I also felt like I wanted to tinker just a little.  :)

Currently, my idea is to sink a reed switch into a straw, with a ring magnet around the straw.  Once the magnet floats down to the reed switch, it lights up the indicator that the alcohol is (almost) gone. Unfortunately, I cannot find a durable non-toxic way to make the magnet float.  I've done several searches and the closest matches I've found are fishing tackle, which I'm not sure would work all that well.  I've found manufactured devices, but $30 per bottle is a bit much to spend.  I'd like to keep it to under $5 per bottle.
