| You need a good quality external D/A converter and amplifier if you want to play audio files on your computer in high fidelity. The missing...
| This design provides an I2C bus connection to the PC’s serial port. From a hardware point of view this serial port version of an I2C interfa...
| This design resulted from the need for a partial replacement of the well-known 8038 chip, which is no longer in production and therefore har...
| A switching regulator with an adjustable output voltage is a handy weapon in the battle to reduce heat dissipation in circuits. The step-dow...
| PCs are not normally equipped with a GPIB interface, however, forcing users to buy a plug-in card or an expensive external USB-GPIB converte...
| The converter we are suggesting building, very simple since it only uses two transistor, lets you convert any S-video signal into a composit...
| Nowadays microcontroller circuits that cannot be connected to a PC are hopelessly old-fashioned. One option is to use one of the many types...
| Sometimes you have a situation where you have a 5-V supply voltage but part of the circuit needs a lower supply voltage. A voltage regulator...
