Some comments about this we saw on the web:

* /u/bad_tenet on /r/BurningMan Sure! For starters I spent months researching eplaya and elsewhere on the web. There are some companies that sell turn-key systems, like Goal Zero, that seem crazy over-priced. I told myself I would’t charge anything to my CC and I’m pretty good at figuring shit out, so I wanted to take a cheaper route. I wanted avoid soldering a bunch of Chinese stuff together if I could. Once I figured out what I needed, I had to look for components…

Panel - I looked at everything from 5 watt panels for fountain pumps to big ass 100 watt panels. I am flying from the East Coast so I needed something portable. I was thinking I need 20 watts to be comfortable, so I looked for 30+ watt folding panels. A cherry-on-top feature would be both AC and DC power. I committed to a DC cooler system but it would be nice to charge phones and power banks too. If I am going to spend some cash, I don’t want a single purpose device. I came across SunKingdom early on but the panels were mad expensive. Almost like Goal Zero expensive. Then one day out of the blue this guy popped up on sale!

I got it for $79! Very happy with it so far. I’ve used it several times already.

*Charge Controller *- This was pretty simple. I found one that could handle the load, was easy to use AND had two USB outs for good measure.

I must confess I don’t know how to “use” it. I plugged it in and it does what I need it to do for now. It has some really shitty instructions (none) so I hope I don’t need to figure out how to do something else with it.

Battery - I am going to buy a 100+ ah battery in Reno but I needed something to test with. I found this 12 v 12 ah battery on sale at Radio Shack for like $12. She told me it was for a discontinued Verizon cable box.

Bucket - I have a few Home Depot buckets around the house as a matter of course. I cut two rows the first time and decided I’d rather have one row of squared off holes instead of two rows of round holes. This way I get a lot of airflow and maximize the water holding capabilities of the bucket. I can probably fit another .75 gallons in my bucket with one row of holes.

Padding in the bucket - Went with FIGJAM’s suggestion for $22. It comes with two in case you fuck one up. Cut to FIGJAM’s spec and adjust as needed but give yourself an extra inch in all measures and fine tune from there.

Pump - I was told 60 gallons per hour (GPH) was good enough so I bought this for $10:

At first I didn’t think it was powerful enough but I had a dead ass battery. After I charged it up, this little guy acted like a freshman going to prom with the homecoming queen. It squirts quite well. I bought 2 more as back up.

Tubes - I bought some tubbing at Home Depot and experimented. It’s took a few rounds of $5 tubes to figure out the spacing of the holes. I heated up a nail on my stove to poke holes in the tubes. Ended up with nice, clean holes.

Fan - VERY IMPORTANT PART - IF YOU CAN’T MOVE AIR, NOTHING ELSE MATTERS My smaller 4 person tent does’t need much so I thought a 150 cubic foot per minute (CFM) fan would be fine. I wasn’t crazy about the horsepower of my first fan that was $8:

So I ordered a 200 CFM fan for $18:

Again, I charged the battery and got MUCH better performance from the 150. However the 200 makes me feel like I ate a York Peppermint Patty so I am using it and taking the 150 as back up.

Connectors - All “raw” cables get connected via these $5.55 things that are very easy to hook up.

My pump and fan need to go to one line so I got this for $4.38:

The “watch this” moment comes by the way of this $6 switch:

I think that is everything. Now I need to figure out how to get a big ass battery from Reno to the Playa on Saturday, pre-gate. I can probably use my camps local asset or ask someone driving in.

——* /u/bad_tenet on /r/BurningMan For controllers, I’ve been happy with this:

It’s simple and the two USB outlets are very convenient. I haven’t tested it on the playa yet but it works great in my backyard!

SUNKINGDOM still has a massive sale going on right now for panels:

For battery, I ’m going to pick up a 100+ AH deep cycle in reno. Even without my 39 watt panel, it should be enough to run my swamp cooler for several hours a day. That said, I like having the back up trickle.

I use similar gauge to wherever my part uses and I use these to connect them:
