Have you ever thought of combine the past and present together? It might be seem impossible to do it, but honestly, it was not as difficult as you think here!
Take a good look on the above figure; it is one of the Ericsson earliest phones. This model (Ericsson DE200) was actually from the 1930s or something. Although it’s an antique, but it fully stored with new wiring and microphone, nickel-plated rotary dial and authentic ring. Yeah, it’s an antique on it’s outer appearance, but fashionable in the inner part!
If you’re boring with the monotonous “Ding-Dong” sound doorbell, it’s time to use your imagination and create this unique doorbell phone!
Ok, first thing first, you must clean your phone with a rag dampened in one of those environmentally friendly orange-based cleaners. After it, you have to check up the capacitors inside the phone is still working or not. Kindly substitute them, if [...] [Via]

AVR has two different programming modes called Parallel Programming Mode (Parallel Mode) and Serial Downloading Mode (ISP mode).
At the Parallel Mode, the device to be programmed is put on the programmer’s socket and +12 volts programming voltage is required to its RESET pin. Communicating between the programmer and the device is done in parallel programming commands, so that the programing speed is two times faster than ISP mode. This programming mode is used to pre-program many devices or/and ISP mode cannot use due to the board design. However, most programmers except STK500 seem not to support this programming mode. Using High voltage parallel programmer can recovery wrong fuse bit setting.

Anyone here that didn’t love to play games, please raise your hand! Yeah, most people love to play games, and that’s why there are many game devices, such Sony PS3, Xbox and Nintendo is available on the market!
For those of the Nintendo lovers, it’s very hard to describe your feeling about Nintendo, isn’t it? Well, if you want to show how deep you love the Nintendo, then Nintoaster is the most suitable project to express your passion on it.
Of course, first thing first, you have to get a toaster. It does not matter if it is a brand new or second hand toaster, as long as it still can function. Then, you need to rip all the main parts out of the toaster and replace them with an NES board. Beside that, the orange LEDs, AC adapter, resistors, pixelglass and controller parts are included inside the toaster.
After that, keep the [...] [Via]

You want to transmit some data across a long distance on a dedicated private network; however, you don’t want to run it over wires, where it could length up to miles? If you have no idea of what types of tools you should use here, then you can consider this Xbee 900 rf!
With this Xbee 900 rf, it allows you to send data up to 15 miles (24 kilometers) without have to connect to any fussy wires at all. For your information, the Xbee 900 rf wireless module send data over the 900 MHz ISM band and enable the information to be sent over great distance.
The 900 modules can traverse up to 6 miles line-of-sight at up to 156 kbps. The boards are part of the hacker-favorite Xbee module series, and it makes it easy to connect these devices to a microcontroller.
For those that need to send private data between [...] [Via]
