The build makes use of a 10 x 20 grid of RGB LEDs controlled by the myRIO. It`s played by using a web interface on any device, as long as you have WebSockets support. [Sam] had originally built it using an Arduino at the heart, but wanted a stand-alone device to do everything ” no extra computer or Raspberry Pi for the web interface. That`s when

he discovered the myRIO ” it`s a pretty cool piece of hardware that we haven`t seen too much of yet, other than the recent Picasso with a Paintball gun project While it`s certainly an impressive sized game of Tetris, we`ve gotta point out the largest we`ve seen, put on by MIT! Or what about the tiniest game of Tetris Oh and where did they get the T-Rex [Linas] reverse engineered an AMOLED HTC 800G—480 screen and interfaced it with an STM32 micro-controller, along with some other components, to make a gorgeously over engineered reflow oven. The real beauty is in the relatively small STM32 chip powering the HTC AMOLED screen. The AMOLED screen is high contrast and has a wide viewing angle, giving it a clear crisp view from all front facing viewpoints. Though pushing the limits of what the STM32F429i can do, [Linas] managed to make a very nice home-grown user interface, complete with user configurable settings and current temperature graphs. The user interface looks very responsive and using some clever programming, [Linas] was able to make use of the potential of the screen to provide beautiful plots and interface widgets. If there`s one thing Bitcoins can benefit from, it`s easier accessibility for first-time users. The process can be a bit daunting if you`re new to cryptocurrency, but [mayosmith] is developing an open Bitcoin ATM to help get coins in the hands of the masses. There are already some Bitcoin dispensers out...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
