It’s always a pleasure to find a hardware hacker who you haven’t seen before, and page back through their work. [Bettina Neumryr]’s niche comes in building projects from old electronics magazines, and ...

A library and simple project for the STM8 processor, controlling an AD9833 Waveform generator. See the wiki here: https://github.com/prosper00/STM8-AD9833-Function ...

Recent guidelines propose N-terminal pro-B-type natriuretic peptide (NT-proBNP) for recognition of asymptomatic left ventricular (LV) dysfunction (Stage B Heart Failure, SBHF) in type 2 diabetes ...

In which we embark on a quest to forge a precise triangle wave, and use that to help set a gold standard for fake sine waves. How well will we fare? A while ago, I needed (or wanted) a pocket-sized ...

The simulator is distributed free of charge and is under continuous development. QSPICE software is an analog and mixed-signal simulator characterized by high simulation speed, accuracy and ...

A design idea with a 555 analog timer that can generate an arbitrary triangle/sawtooth with its waveshape and frequency controlled by pots. If you could assemble the list of all the oscillators that ...

Function generator or waveform generator is an integral part of electronics and used to produce various kinds of waveforms like a sine wave, square wave, Sawtooth wave, etc. We have already designed ...

In electronics, waveforms are mostly plotted against voltage and time. The frequency and amplitude of the signal can vary according to the circuit. There are many types of waveforms, like sine wave, ...

The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...

Small DC motors are efficiently controlled using pulse-width modulation (PWM) method. The circuit described here is built around an LM324 low-power quad-operational amplifier. Of the four op-amps ...
