This article explains how the LMC555 timer chip works, from the tiny transistors and resistors on the silicon chip, to the functional units such as comparators and current mirrors that make it work. The popular 555 timer integrated circuit is said to be the world’s best-selling integrated circuit with billions sold since it was designed […]

If you’ve played around with electronic circuits, you probably know[1] the 555 timer integrated circuit, said to be the world’s best-selling integrated circuit with billions sold. Designed by analog IC wizard Hans Camenzind[2] in 1970, the 555 has been called one of the greatest chips of all time with whole books devoted to 555 timer

When you think of high-throughput ptychographic cytometry (wait, you do think about high throughput ptychographic cytometry, right?) does it bring to mind something you can hack together from an old Blu-ray player, an Arduino, and, er, some blood? Apparently so for [Shaowei Jiang] and some of his buddies in this ACS Sensors Article. For those of you who

The QianLi’s 160×120 thermal imaging sensor and 1920×1080 visible sensor combine to make a powerful circuit board repair tool, especially helpful in finding overheating or short-circuit issues. Saelig Co. Inc. has introduced the QianLi LC-IRP01 Thermal Imaging Camera, a diagnostic tool for PCBs which displays heat images to help identify damaged or malfunctioning components or short-circuits.

For this first edition of the hardware teardown, we’re dissecting technology and lifestyle brand Withings’ cheapest activity and sleep tracker: the Withings GO.  Since they launched their first connected weighing scale back in 2010 (the WiFi Body Scale), I’ve been a big fan of Withings. They make beautiful products that integrate seamlessly with their online

I’d like to share my latest project, a scanning laser microscope with you. Some words concerning the principle: The pinciple is quite simple. The laser beam is focused on the object and the reflective light is being measured with a photodiode (in my case a BPW34). To focus right the current through the focusing coil

Smartphone microscope as the name implies is basically a microscope which is compatible with a user’s smartphone. They mostly made up of a soft pliable lens and uses the smartphone’s camera. Smartphone microscopes have been in existence before, they are based on the use of external LEDs and usually get powered from an external source, these attachments

Remember the old video game Space Invaders? Some of its sound effects were provided by a chip called the 76477 Complex Sound Generation chip. While the sound effects1 produced by this 1978 chip seem primitive today, it was used in many video games, pinball games. But what’s inside this chip and how does it work

At the risk of putting too fine a point on it, Hackaday exists because people are out there building and documenting open source gadgets. If the person who built a particular gizmo is willing to show the world how they did it, consider us interested. Since you’re reading this, we’ll assume you are as well.
