Hi doers, its very simple to ignite a candle with more light.
Make an effective Live Trap at Home
By ADJHi doers, building a trap is not much hard, we can build traps with very less materials which we can get around us. this is a simple and effective method i used to transport stray cats. "This is a Force to Force deal"
Things you will need
1. Metal net or woods.
2. pieces of hard wire.
However make a rectangular shape cage with one side open to fix a door. Height x width x length of the cage is up-to you, estimate a relevant ratio according to the targeted animal.
For Asian Cats i used height= 8 inch, width= 8 inch and length= 15 inch.
It cost $0 for me because i used the materials which i could get from home around. but if you need to do a fresh one may be it will cost about $10.

Build a Baking Powder Submarine
by Phil B
I have long wanted to build a baking powder submarine from commonly available materials. I had one of these in the 1950s when Kellogg's gave them as a prize in cereal boxes. Those were a little over two inches in length. A couple of years later l saw a much longer one in a store window. Mr_o_uk got me thinking about it again with his Baking Powder Diving Submarine Instructable, but his is a concept submarine he has not actually built. There are some practical problems I had to solve before my concept would be a working bathtub submarine that goes to the bottom, rests there, rises, discharges a bubble of CO2, and sinks to the bottom again in endless cycles until the baking powder is depleted. I have done that in a way someone reading this Instructable can replicate.

Vertical Pallet Garden
by L.A.Woman
I moved from a house with a huge back yard to a place with a pretty nice sized balcony. As much as I love to garden, space was going to be a challenge as well as dealing with potted plants. I needed my herb garden (because, who doesn't NEED fresh herbs?) but I had no desire for little pots to be taking up ground space. Solution...build UP! So here is my lovely vertical garden made from an upcycled wooden pallet, some recycled pots, and metal wire. The entire thing ended up costing me about $30.
WHAT YOU WILL NEED:
At least 1 wooden pallet
As many pots as you have plants/seeds
Potting soil
Metal wire (i used 100lb wire)
Wire cutters
4 wood screws
Screwdriver
Outdoor paint in your favorite color
Paint brush or small roller

Emergency Light/Charger from Fire & Water
by Joohansson
Really simple and very useful Thermoelectric Emergency Generator from very few parts available in home.
Optimized for powering with tealights/candles.
Optimized for powering with tealights/candles.
Background:
It converts heat energy (from candles) into electricity. Main usage is to power LED lights to act as an emergency product. It could also be scaled up and used in homes where electricity is not very given. It could also be used as a battery charger or power other electronic devices. I´m well aware of the commercial product tPOD1 which I think is a great idea but I´m more interesting in a DIY solution for everyone.
Concept:
I´m using a thermoelectic module, also called peltier element, TEC or TEG. You have one hot side and one cold. The temperature difference in the module will start producing electricity. The physical concept when you use it as a generator it's called the Seebeck effect. Thermoelectic modules are mainly used for the opposite effect, the Peltier effect. Then you apply a electric load and it will force a heat transfer from one side to the other. Often used in smaller refrigerators and coolers. Read more about i here:

Solution:
First I used a cheap TEC-module (8€) but it was unfortunately destroyed due to high temperatures. It was specified to handle 200ºC max temperature but somehow I got higher temp than I measured. I ran it without load, that might be the cause. I now use a 40x40mm TEG-module that produce 5.9W (4.2V/1.4A) at 180ºC difference. It has a maximum operating temp of 350ºC (180ºC cold side). It was the same module I used in my other charging project. It´s quite expensive though, about 50€. TEGs are a bit hard to come by but I think there are cheaper ones available.
To transport away all heat and cool it with air you usually need a large heat sink, or a small heat sink with a motor and fan. In this project I use water instead. That make the contruction really compact and the temperature on the "cold" side will never exceed 100ºC. Water will eventually boil but it´s easy to refill, as long as you have water.
To power LEDs you need higher voltage than the module itself produce. In my previous project I built an adjustable regulated voltage Step-up. That could be used (and is better) but I choose to use a $1 step-up from Ebay.
The best choice of heat source is 3x tealights. That produce about 0.2W electric power.

How to make a RC toy car in home
Posted by Swagatam Majumdar
The market may be full of these hi-end remote controlled toy cars, but for a hobbyists making one at home can be entirely a different experience. The article below explains how to configure a simple remote controlled toy car using a ready made 4-relay remote control module.
If you refer one of the previous articles you will find some data regarding buying of ready made, ready to use remote control modules or devices, which just requires to be wired as per the data and you are able to control any electrical device within a range of 100 meters with a press of a button over the remote handset.
Here we are using one of these ready made remote control modules for implementing the remote car operations.
In this article only the circuit and the wiring part has been discussed, making the car body and fitting of the motors and the wheels will be entirely left on the user, the user may take the help of a carpenter or some fabricator for designing the vehicle body.
The remote control module which is being discussed here uses four discrete relays, which can be toggleed discreretly through the 4 individual switches over the remote handset.
The model car is provided with four wheels, two at the front and two at the rear as usual vehicles have.
The remote control unit may be procured ready-made, the one discussed here will be just perfect for the present application.
Moving back to the proposed project of a simple car remote control, we will need the following components for making the main control units of the system:

Tips
Top 10 Fishing Tips for Beginners
Below is a list of the beginning fisherman’s essential 10 things that beginners needs to know when packing up your gear and heading towards the water. In order to ensure a successful fish fry, you must know the most beneficial basics.
1. Do your research.
Before you cast that first line, make sure you have a general idea about what you are getting yourself into. There are plenty of fascinating fishing books that can all but put you right in the middle of the action before you even pick up a pole.
2. Understand the basic procedures.
Once you have some reading under your belt, you can start by beginning some pre-fishing skills. Get familiar with such tasks as adding fishing bait to hooks, casting your line and tying knots before you’re drifting with the wind in your boat.
3. Choose the right equipment for you.
Beginners will benefit the most from a specific rod and reels that are simpler for someone who is just beginning to cast. Open-faced fishing reels are never recommended for somewhat just starting out.
4. The bait is the main course of fishing .
Be aware of what fish you are trying to catch and what kind of bait attracts them. Catfish, for example, respond to either specially made bait for catfish or even raw chicken liver while bream fish like insects like crickets. The wrong bait could mean a long fishing trip.
5. Location, location, location.
Have an idea of where your fish have chosen to spawn. Finding these locations lead to a great deal of fish.
