    Solar Power Bucket

    Nice! Just add good gauge wire and claps and you have a jumper pack. I'm inspired to make similar with a deep cycle batt and may seek a more square bucket. good square buckets are hard to come by but pack better. shoot you can have a 12v evaporative cooler run of your solar bucket bank make a stool out of your setup and chill out on it.

    Figjam's Swamp Cooler

    Not sure that is the case, and I sure want to know. if the h20 is cooler but not ice will that mean more evaporation perhaps even cooler evaporation by the warm dry air flow through and over the wicks, I believe so. of course a chunk of block ice wouldn't wick.Warmer water well the closer the water is to the ambient temperature less cooling.....correct?The drier the air the better, this I know.Some expert schooled in the sciences better that I please give us the science (outside of the relative humidity. will ice water work better at cooling in an evaporative cooler that water x degrees below ambient temperature or is there some ideal gap for the evaporation point of water......I'll try both ways on my swampy for a proof is in the pudding response.

    Without having profound electrical knowledge. a motorcycle battery and a 10 to 20 watt solar panel should do the trick. there is a nice price point on 50 watt solar panels and they are a convenient size. so why not.You can get the numbers you need off your two "appliances" your fan and your pump and match that too your panel/ batts. I'll post my numbers. Please correct me if I'm wrong with your best nice folks, but you can not really oversize your battery, you just need enough electricity from your panel to charge what your swampy and??? are drawing factoring in for losses. I have a feeling there is a balance here to be achieved: too much water pumping over the wick: not enough evaporation. too many cfms of air could be too much evaporation of just defuse the nominal cooling??...see more »Without having profound electrical knowledge. a motorcycle battery and a 10 to 20 watt solar panel should do the trick. there is a nice price point on 50 watt solar panels and they are a convenient size. so why not.You can get the numbers you need off your two "appliances" your fan and your pump and match that too your panel/ batts.

Ay yi yi, I'll post if achieved.On amazon and else where there are solar submersible pumps that come with a 5-10 watt panel, it may be that that would run the fan too and if you just want a daytime solution you could skip the battery "bank" perhaps. there are some decent battery operated fans that also will run off 12 volt. one could mount one of these and use rechargeables. A nice jumper pack in conjunction with a solar panel is a great way to go. This is how I run my ARB fridge freezer which draws far more than a small DIY swamper. Also ideally if you are "boondocking": you want you place of rest in the shade and your panel in the sun, so you want long leads of the correct gauge or other portability.

    I tried to reply to specific comments below, the one about adding ice for my latest comment.and the one about how big a solar panel for the latter comment. Instructables wasnt working right, I'll try and move them later: Be cool! Ha.

  • Portable Evaporative Cooler (swamp cooler)

    I attend more n likely the same hot dry dusty gathering. Many years we have lucked out and had some 110 to run AC's or wall plug swamp coolers. Not so this year at Chilleville. Your unit is mondo and your awesome flip pac camper with the requisite silver bubble insulation probably has similar cooling needs to my Alaskan pop up camper. How many Gallons of agua are you going through on a typical blistering playa day nap? Or lets just keep it per 24 hours average. I was thinking a 5 gallon bucket or ice chest style within my camper might do the trick. I wonder if there is a cooling advantage or disadvantage to having your evap cooler inside rather than outside. Better brush up on thermodynamics.

I guess at some point the humidity inside a structure would make it so the cooling effect of evaporation was diminished. didn't notice this when using a plug in one inside a van one year. Is Bill Nye a burner? Very interested to know how much H20 your mega swamp consumes, gracias.

  • Ultimate Night Vision Headlamp - 500+ lumens with only 8 watts

    CraigL20 Both those companies make bikes for biking in the 500 dollar range in the present day. (check out the seca 2200, and if you needed to do a 24 hour race you'd need additional battery packs) I believe the bulk of light and Motion Lights are built in Monterey. Not sure if anyone uses HID anymore. I imagine it has its place.

    I was going to ask, Why not red light for nighttime sports.....this article on lighting and backpacking explained to me well the pros and cons of red versus grey (blue green) and full spectrum lights and optimizing ones own night vision.https://backpackinglight.com/00202-2/And this is even better, argues dim white light is often better for seeing at night that red or cyan/bluegreen http://stlplaces.com/night_vision_red_myth/
