With the phasing out of game, serial and parallel ports from modern computers and the ever increasing popularity of USB, it makes sense that hobbyists start getting to grips working with USB. Unfortunately, USB is not a simple protocol and can be daunting to viagra online paypal implement. Luckily, there are several solutions on the market that ca

n make implementing a USB device much easier. This project focuses on the use of a USB PIC and the mikroC compiler to convert an old game port joystick to utilize USB. One of the advantages of the mikroC compiler are the built USB HID libraries that make creating a USB HID device a doddle. When writing USB code using the mikroC compiler, the USB device produced is a generic HID device that can be used to transfer data to and from the PIC. However, it is possible to modify the USB descriptor generated by mikroC so that it produces a specific USB HID device, like a keyboard, mouse, joystick or graphics tablet. The 76H1571 is a 4-button joystick with a throttle and POV hat. What`s interesting to note is that you can`t use the throttle and POV hat at the same time you can only use one or neither. The two slide switches on the viagra prescription online front of the joystick are used to switch the throttle and POV hat on and off, so that you could choose which one you wanted to use. Because there is no point for this restriction with USB, the converted joystick will be able to use both the throttle and POV hat at the same time. This then makes the two switches at the front redundant, so why not add those as two extra buttons When the compiler generates the USB HID code, it creates a descriptor that is sent to the USB host that tells it what type of USB device it is. A HID device descriptor is slightly different as it has an...
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.....
