The PLD (programmable-logic-device) code in Listing 1 creates arbitrary-resolution, pulse-width-modulated (PWM) generators. PWM generators are useful as low-bandwidth D/A converters in hardware of ...

Having the right tool for the job makes all the difference, especially for the types of projects we feature here at Hackaday. [Jana Marie] must agree with this sentiment, one of her latest projects ...

Quick video, just milling a mounting bracket for the motor shaft. Rather than a grub screw, the d-shaft is sandwiched between ...

In LCD backlight applications, a dc-to-ac inverter drives cold-cathode fluorescent lamps. The inverter's input comes from the display's power supply. Currently, it spans from 12 to 18 V. Pulse-width ...

PWM waveforms are commonly used to control the speed of DC motors. The mark/space ratio of the digital wave-form can be defined either by using an adjustable analogue voltage level (in the case of a ...

Linear Technology announces the LT8500, a pulse width modulation (PWM) generator with 48 independent channels. Each channel has an individually adjustable 12-bit (4,096 steps) PWM register and a 6-bit ...

Linear Technology has unveiled a new pulse width modulation (pwm) generator with 48 independent channels. According to the IC specialist, each channel has an individually adjustable 12bit (4,096 steps ...

We love little tricks like this. Suppose that you want to generate an IR remote’s signal. It’s easy, because most of the codes are known. But it can be slightly harder because most IR remotes and ...

I have had an on-going mission to design a universal-ish pcb that will convert a PWM waveform at one frequency into to another frequency while retaining the mark-space ratio. The obvious answer is a ...
