If you are looking to get into the spy game have a look at your first gadget you need here, it is a Mini FM Transmitter.

“It transmits FM waves so you could easily receive the signals on your mobile phone, radios, etc. As the name and the picture indicates it is very small and is approximately the size of a 9v battery clip. With this FM transmitter you could start your own mini FM station. The circuit uses BC547 transistor to amplify the signal and then frequency modulate it. It uses “frequency modulation” most commonly known as FM, the same principal to transmit audio signals captured by the microphone.

Components

BC547 Transistor
An microphone
A variable capacitor 47pf
An Inductor (see steps for description)
4.7k Resistor
330ohm resistor
1n capacitor (102)
10p capacitor
9V battery
LED(optional) “

Richard Turere Invents Livestock Protection Device

 Richard Turere Invents Livestock Protection Device_2

 13 year old Richard Turere lives in Kenya. Livestock is very important in their community, however lion are very smart and often kill their animals. The lions wait till everyone goes to bed before attacking. The first attempt at outsmarting the lions was to build scarecrows but the lions soon realized that since they were not moving around that there were not real people and didn’t pose and danger. Using a solar panel to gather electricity, a battery to store it and a car turn signal flasher to blink some lights he was able to place some lights at random locations around the pasture. This makes the lions think that there is someone walking around watching over the livestock at night. What a ingenious idea from such a young inventor.

 Maker Camp Season 2014

 

 Check out Maker Camp 2014, a great way for kids to have some fun building projects. Check out the guest Buzz Aldrin who was a guest in the video below. There are some audio issues that make the video a bit hard to watch but if you can get over that it is worth it.

About Maker Camp

Maker Camp is a free summer camp for building, tinkering and exploring available online and in local neighborhoods. Through Google+, YouTube and local “campsites” young inventors and artists around the world can make awesome projects, participate in epic virtual field trips and meet the world’s coolest makers.

 On Mondays through Thursdays, new projects are introduced every morning by an expert “Guest Maker” who walks campers through the steps to making the project, offering tips and advice. In the afternoon, the mentor hosts a Google+ Hangout on Air to offer campers a chance to ask questions, and share their projects with photos and videos. On Fridays, the Camp Director hosts a virtual field trip to epic destinations via a Google+ Hangout-on-Air, broadcasting a live experience to anyone who wants to tune in on Google+ or YouTube. This year, campers will get to visit Google’s self-driving car group, NASA, Disney, LEGO and more.”

Yesterday we looked at an entry level DIY thermostat project. If you want to go all in with processing power and features have a look at the Open Source Android Thermostat Project. It is based around the IOIO-OTG and uses the TMP36 temperature sensor. A small custom PCB is used to hold the handful of components that make the control side of things work and you simply connect up your Android device for an instant great looking screen with touch interface.

 “Android Thermostat is an open source thermostat project ideal for programmers and electronics hobbyists. As the name suggests the application runs on Android phone that is connected to some basic electronic components for controlling your home HVAC system.It costs around $140 to build and can be assembled in an afternoon.

It has several advantages over a traditional thermostat including the ability to easily create multiple schedules that are as simple or complex as you like, remote control access, monitoring of usage and easy updates over the internet. It’s API and open source nature means you can further customize the thermostat to perform additional functions. “

Arduino Thermostat Project

Arduino Thermostat Project

 

If your thermostat just stopped working you could go to the store and purchase a new one but why not make your own. You can add any feature you like, want to control it from your smart phone? Add an ethernet module and go for it. Want to add schedules? Add a RTC and you can program timed temperature settings to your hearts content. Want to make sure the average temperature in your house is kept to a certain temperature? Add multiple sensors in various areas and average them together or add some dampers to control the air flow in various zones. Your imagination if the only limitation.

This Arduino Thermostat Project by Dylon124 is just the basics but from this starting place anything can be done.
