Don’t mind the post title as this DIY shows you how to make hydroponics unit for growing anything.

Aside from people with medical marijuana licenses who live in San Francisco and can legally grow several pot plants, the hydroponic system can be used for growing your own organic vegetables and what not.

My wife teaches 8th grade science. This project “The Hydroshack” is a rendition of one I built over 20 years ago in my college teaching methods class. It is designed specifically for performing experiments in a science class. It therefore incorporates some modifications for flexibility and control purposes. It also needs to be collapsible for storage in tight quarters. If you are considering building something similar for your home, it can be less complex.

Of course, if you don’t want to build one yourself, here’s some resources too:

Hydroponics.com sells bunch of nutrients and other hardware needed for home-growing.

All about Hydroponics at Wikipedia.

Hydroponics.net sells bunch of stuff for home-growing too.

Here’s a cool DIY Flame Thrower project that will remind you of X-men characters.

Definitely this isn’t as powerful as anything in the movies but will burn most things off pretty fast.

The Pyro System is my final project for a mechanisms class in the spring of 2008. It gives me the power that the X-Men character Pyro has

Here’s a fun DIY on how to make a chapstick LED flashlight.  It’s pretty simple to do but a great idea.  Maybe Chapstick companies will pick up on this and make them as promotion materials.

This is an instructable on how to make a flashlight out of a ChapStick tube. After reading up on multiple LED instructables I thought it would be neat to make an original design that had not been done before. Since button cell batteries can be expensive, I went with an A23 (12V) battery that cost less than $2.00 for two.

Here’s a fun little project.  Get a PC fan, a sawed-off USB cable, and some carboard to make a cheap USB Vacuum running off 5 volts DC.

Here’s a really cool DIY on how to make a PID controlled fridge.

For this project, you will need to grab an icebox, thermoelectric cooling part, and a PID.

Heck, if you want to skip the steps, you can also get a Kimchi refridgerator, which does the same thing.

I had an old beer cooler sitting in the garage that Kylie picked up on the street a while back. It uses a Peltier thermoelectric cooler to cool the inside and can achieve sub-freezing temperatures.

Since I didn’t want to leave the cooler on constantly, and below freezing is actually too cold for solder paste, I decided to add a PID controller to the cooler to create a solder paste fridge for the garage. To do this, I needed the following items:

Here’s a cool DIY Arduino and Wiimote Controlled Boat all by flick of the wrist.  Now, just don’t drop that Wiimote and you will have some serious trouble getting out of the water.  (I am sure there’s a backup plan for that)

Last winter I decided version one was successful enough that I would dare to improve it. My design constraints were to extend the boats range to about 20 miles and add a second motor to balance the thrust and push the extra battery weight. In my nerdiness, I also figured it would be prudent to drive the boat with some sort of joystick, opening up the option for autopilot in the future. Lastly, I need to walk the boat to the water (0.3 miles) on a portage cart and launch and retrieve it by hand.

You could probably take any cellphone adaptor and convert it into an iPhone charger pretty easy but here’s a cool DIY showing you how to make your own iPhone charger.

All you need are the 4 resistors stated above. I have modified some values of the resistors because of some miscalculation. Connect them as shown and provide the circuit with a regulated 5v supply. Get a female USB plug and connect it as shown to the circuit. Make sure the positive and negative terminals are connected correctly. The D+ and D- pins have low currents so connecting them wrongly may not blow up your iPhone.

Here’s a cool DIY on how to make an LED Cube!

64 LEDs makes up this 4 by 4 by 4 cube, controlled by an Atmel Atmega16 microcontroller.
Each LED can be addressed individually in software, enabling it to display amazing 3d animations!

I too, admit to having to endure endless months without money to buy a new wallet.  Here’s a great way to make a paper wallet when you are hopeless to even buy a $5 wallet.

One sheet of 8.5 by 11 paper folded, with minimal cutting, and one piece of tape = durable, seamless, useable, write-onable, minimalist wallet.

If you are outdoors a lot, you might want to consider making your own DIY compact survival kit and customize your emergency needs.

Wilderness survival should be taught to everyone. It can save lives, thus is an important body of knowledge. A survival kit should be cheap, and it should be simple, as this encourages more people to carry them when they go into the outdoors. In this instructable I will show, and explain how to make wilderness survival kit, and how to use it.
