This allows the computer to synchronize all its components and it determines the speed at which the computer can pull data from its memory and perform calculations. When you talk about how many gigahertz your processor has, you're really talking about clock speed. The number refers to how ...
been around PCs for many years, you probably remember that the original PCs had large red toggle switches that had a good bit of heft to them. When you turned the PC on or off, you knew you were doing it. These switches actually controlled the flow of 120-volt power to the power ...
Many incompatibility issues between a USB Host and connected device can be predicted by a mismatch between the USB Device's descriptors and the USB Host's support of the device. Dumping the USB Descriptors of a USB Device Reading USB descriptors is something every computer with a USB port can...
There are other articles, many of which are linked in my signature, that can provide the background for these terms.> <Note 2: This article is very long. There are not any good shortcuts to understanding the problem and complexity of signal chain analyses. Trying t...
when the Teensy is controlling the LED. It may take some experimenting to determine the current level that gives good brightness. I've had good luck using 715 ohms on several keyboards which used 2ma LEDs. Depending on how the LEDs are wired, the Teeny will either drive the control signal...
Of course, most microphones that can be connected directly to your phone are not of excellent quality, but there are many great options you can choose from. Besides, all of the options are definitely better than your embedded Android mic. Plus, you can theoretically choose a microphone that ...
My amplifier makes much more power than my speakers can handle, will that be problem? Some speakers can handle more power than rated without getting damaged, some may not. To ensure you are not getting more power to them, use nominal impedance rating and ohms law to determine how high shou...
Many SPI-based products for Arduino do not work well together. My hope is this information can help all makers of Arduino compatible devices to achieve much better compatibility. Long-term, sharing of knowledge is needed. Please share this information and ask makers of SPI devices and libraries...
Some of the most powerful transistors I have used, come out of old CB radios, such as the 2sc2078, 2sc2166, 2sc1971, 2sc3133, 2sc1969 and 2sc2312. There are many others. As an example, the 2sc2078 with a 20v laptop PSU, gave 10-12W of maximum output power into a 50 ohms ...
a manual machine, as well as many tasks that humans simply aren't able to do. Whether it's cutting a sinuous curve into a heavy steel plate, or engraving a miniature image on the back of a gold watch, CNCs can do it faster and with greater accuracy than any other type of machine....
