Making model train layouts is a great hobby, automating it will make it a lot better! Let us take a look at some of the advantages of its automation: Low-cost operation: The whole layout is controlled by an Arduino microcontroller, using an L298N motor driver, their cost is almost nothing as compared to traditional train control […]

Got a couple of old DVD-RW drives lying around, just collecting dust? Of course you do. If not, you likely know where to find a pair so you can build this totally adorable and fully dangerous laser engraver for your desk. Check out the complete build video after the break. [Smart Tronix] doesn’t just tell you to

Something like 99% of the people on the road at any given moment will consider themselves an above-average driver, something that’s as statistically impossible as it is easily disproven by casual observation. Drivers make all kinds of mistakes, but perhaps none as annoying and avoidable as failure to use their turn signal. This turn signal

Oscilloscope displays have come a long way since the round phosphor-coated CRTs that adorned laboratories of old. Most modern scopes ship with huge, high-definition touch screens that, while beautiful, certainly lack a bit of the character that classic scopes brought to the bench. It’s a good thing that hackers like [bitluni] are around to help

Over on Hackaday.io, user [Tomasz Jastrzebski] has designed a tidy-looking custom controller for driving temperature-controlled soldering irons. The design is intended to be general purpose, capable of operating with irons rated for different voltages and probe type, be they thermocouple- or thermistor-based. Rather than integrating a power supply, this is handled by an external unit, giving

Automotive lighting as an important safety and popular design feature in vehicles has evolved rapidly in the past years. Now, Nichia Corporation and Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) start a collaboration to add further momentum to this evolution. Together, they are developing a high-definition (HD) light engine with more than 16,000 micro-LEDs for front light applications. Unlike current
GaN Systems and ON Semiconductor announced the availability of the NCP13992UHD300WGEVB, the world’s highest power density 300W ac-dc adapter reference design using GaN Systems’ 650V, 15A gallium-nitride (GaN) E-HEMTs and multiple ON Semiconductor controller and driver ICs, including the NCP51820, NCP13992, NCP1616, and NCP4306. This complete system reference design is a highly versatile and low cost, allowing designers to

It’s been a long time since my previous tutorial, my work is quite busy and I spend less time on Instructables. This time is a project that I like very much since my first saw it on Kickstarter: Air Bonsai. I was really surprised at how the Japanese made it, really a beautiful and mysterious piece.
