This is the beginning of a project I've been wanting to do for a while now. I'm just learning microcontrollers and electronics, so anyone if there is anyone out there who notices me doing something stupid, please let me know. I have a 12-gallon Nano Cube reef aquarium. I want to automate as much of the maintenance as I can. I'm going to start with adding top-off water. This is Topper v1.0 and like any vX.0 you can count on it having problems.Now I know some of you are probably wondering why I don't write this up as an instructable. Well, that is on my list, but it has a ways to go before its ready. I mean, take a look at it! Isn't that the ugliest thing you've ever seen?When the whole thing is finished and prettied up I'll make an instructable out of it. Eventually I'll want to switch to an AVR microcontroller because of the cost. But the Parallax Basic Stamp is just so much easier for quick and dirty programming.Here is the initial controller program.'---------------------------------------------------------------' FloatSwitchTest.bs2' First attempt to control the top off pump with the Stamp' {$STAMP BS2}' {$PBASIC 2.5}DO IF (IN15 = 0) THEN 'Reads float switch HIGH 14 'Turns on pump HIGH 6 'Turns on LED ELSE LOW 14 'Turns off pump LOW 6 'Turns off LED ENDIF PAUSE 1000 'One second pauseLOOP'----------------------------------------------------------------This is just to get things started, but already its nice not having to top it off every day and even at that, the swing in salinity was more than I was happy with.The pump is a Tom Aquarium Products AW-20. At 3.5 gph and a 30" head, with nearly that from top off water to tank and a "one way valve" I wasn't sure how often it would come on or how long it would run at a time. So far, its been running 3-4 times a day for 35 - 40 seconds at a shot. I've started adding Kent Marine Superbuffer-dKH to the top off watch. I want to keep it at about 10 dKH.Anyone looking closely at the photo will notice an IC not listed on the circuit diagram. Its a DS1302 real-time clock and microcontroller isn't currently using it. Next up is connecting that and a 16x2 LCD display to show the time and track how long the pump runs.All comments are welcome, from "I'm curious why you..." to "ARE YOU INSANE?!?!".

snuggle mattress topper

I love this mattress concept Creating a whole mattress seems pretty ambitious, however a mattress topper of a similar concept  seems like an affordable simple way to emulate the concept. when i started looking into materials I was really astonished by the foam thing. there are lots of different kinds all in different density and thickness. What type of foam would be suitable for a project like this?

Ideas and Methods for DIY Truck Topper

So in 5 months starting February I'll be getting my first vehicle. If I do get a truck, I'll be making my own topper out of wood. Now I have a reference picture but I want it out of wood just because it's more secure and looks pretty. Also because I will be making a door on the back that stands tall but can also be walked through. The first two photos is how I want to make the topper but I need methods and advice to do so. The third picture is how I want the door. I'll try to answer any question when you have them but keep in mind I don't currently own a truck, this is for 6 months down the road.

LED Pizza Delivery Car Toppers

Hi, I'd like to replace wired lights in our pizza car toppers, which run through windows into cig lighter, or run into hood and attach directly to battery -- with --- LED lights mounted in the car toppers, but wired so on and off switch is mounted on outside of car topper. This way there are no wire outside of the car topper, and drivers could just flip the switch on car topper itself to turn on and off.

champagne topper jewelry

On our wedding night my wife and I had a bottle of Vieve Cliquot champagne. I still have the topper that holds the cork to the bottle. I can imagine it being made into a bracelet or pendant for my wife but would have no idea how to go about it. If anybody has any ideas I would appreciate it. The topper has a portrait of the widow cliquot on it and reminds me of a cameo. Our five year anniversary is coming at the end of this month and I would love to make her something out of this for it.

Wedding Cake Toppers

Since samesex marriages became legal here in Sweden two days ago it is becomming clear that no one is making those little figures that go on top of the cake in more than one theme (guess wich one). There is the usual pair but they're often plastic molded as one piece and needs a LOT of work to mod. We need an instructable showing how to make, mod, mold, sculpt, massproduce or even bake toppers for Gays, Lesbians, Bisexuals, Transexuals and Transvestites (I've probably forgotten someone).

12V LED to Battery Power?

Hello! I'm just getting my own cab company started in my medium sized town, and to begin I'll be using my personal vehicle - thus, I'm using items I can remove so I don't get harrassed on my days off, such as magnetic decals and a magnetic top light. My question is this: Is there a way to convert a 12V, 96 LED light over to battery power? The toppers use a direct cable to a car charger port, but I hate having that cord just hanging out in my cab. It is tacky and unprofessional - at the same time, I very much do not want to punch holes in the top of my car and wire it to my dome light. I have found several rechargeable, compact 12V batteries online, but I've no idea how I'd hook them up. I'm smart enough to know that I can't just wire it directly to the device - the battery would last minutes at most. I think I'd need some kind of transformer, perhaps? Any suggestions? And here's the battery I would use: Voltage: 12 Lead Acid Type: General Purpose Capacity: .8AH Chemistry: Lead Acid Lead Acid Design: AGM Product Category: Sealed Lead Acid Terminal Type: WL, Wire Leads Weight: 0.8 lbs Length: 3.78 in Width: 0.98 in Height: 2.4 in

Interesting TAP handle tech question \ quest.

Here's a weird one for  you guys. I recently bought a Beer tap handle and noticed that it had an insert that had some LEDs on it. Cool. The problem is that the LEDs don't light (beyond a tiny SMD red LED heartbeat). I found a small button that when depressed seems to trigger a test. Bright white LEDs on the top and bottom flash to illumnnate the top of the tap (either a clear baseball or FIFA tap topper) as well as the body. It's hollow plastic so it briefly glows. The problem is that I can't figure out how to light the things beyond the test (for which you have to remove it from the handle). The guy who sold it to me said they've sold lots like this and could never figure it out. I figured light sensor? nope. Tilt sensor so it'll flash when you pour a beer. Nope. I broke out  my loupe and noticed a funky thing on the circuit board that looked like it had an antenna. It was an Anaren A1101R09A. This thing is a radio tranceiver!  That tells me there was a remote with it that was lost in the few days after they bar got their new tap handle. Does that sound right? If so I was wondering where I could get or build another. I could put together some other LED solution, but I'd love to get this to work. HEre's a pic of the tap handle and the insert laying on it's side. The right side is the up side with the transceiver. It's blue if you look closely. Not sure I'll get a solution, but there's some clever people here, so you never know. Thanks for reading.
