A new project soon to be available via the Crowd Supply website has been unveiled this week in the form of the ATtiny Flasher, an open hardware flashing tool specifically designed for the Atmel ATtiny ...

I read the wiki since I was interested in what specific IC I should buy. I'm particularly interested in the Attiny25 variant in a soic8 package. The cheapest one @ farnell seems to be the ...

In a compensated mode LEDs will have the same brightness regardless how many LEDs are shining. Every enabled LED will shine no more than 1/20 of animation frame time. Resistors should give up to 10-15 ...

The heart of our ultrasonic generator is a ATtiny25-20. To avoid the animals from becoming habituated, it generates a burst of roughly 1 second every 10 seconds. Since we humans cannot hear whether ...

I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

In response to the limitations posed by fixed-design, Arduino-style boards, Elektor has designed three mini-development boards that give developers more flexibility while still hosting the ...

Function generators are a handy bench tool to have around, and while you can usually cobble something together that works, it is much more handy to grab a device when you need it. Thats where this ...

The device uses an ATtiny25 microcontroller as it introduces a new design for a universal gear indicator that can be fitted to any motorcycle. The project consists of a main circuit that includes a ...

Most multimeters today have an auto turn-off feature built in. There is enough space in a multimeter enclosure so why not to install a simple circuit that would take care of this? Figure 1 shows a ...
