Hello, I’ve now reworked the AnimatedGIF and Light Appliance sketches into hopefully their final form and I will stop spamming this list so often. If you go to craigandheather.net/misc you will find the following files: Lindley_Animated_GIFs_Collection.zip which is a collection of GIFs used by both AnimatedGIF and LightAppliance sketches. Lindley_AnimatedGIFS_V1.2.zip which is the new version […]

Modern devices are quickly switching to USB-C power adapters, gradually fading out USB-A, and USB-B adapters. USB’s Power Delivery (USB-PD) protocol enables the supplies to be flexible enough to handle charging (or powering) devices ranging from mobile phones to laptops. There are many high quality 90-100 Watt USB-C power adapters available. But unfortunately, there are many devices that

The oldest form of television used a spinning disk with a progression of holes — a Nipkow disk — to slice the image into lines for display. They’re surprisingly simple machines and capable of unexpectedly high-quality images despite their relatively low resolution. Even better, in an age of microcontrollers and bright LEDs, making one that

If there’s something weird in your Network Neighborhood, who you gonna call? If you want your WiFi troubles diagnosed in style, try calling [Travis Kaun] — he might just show up wearing the amazing Pwnton Pack. Built from a replica Proton Pack similar to those used in the 1984 classic Ghostbusters, it’s a portable wireless security diagnostics

Affordable and reliable cell phones have revolutionized the way we communicate over the last two decades or so, and this change was only accelerated by the adoption of the smartphone. This is all well and good if you’re living in a place with cellular infrastructure, but if you’re in more remote areas you’ll have to

These days, streaming services are a great way to listen to music or podcasts on your computer or on the go. However, they lack one feature of the MP3 players and streamers of old: visualizations! [mircemk] is a fan of those, and has built a hardware spectrum analyzer that pumps with the music. The build relies

Acrosser ACM-XD15MT COM Express Type 7 module is based on the Intel® Xeon® processor D family, and available in 8 core versions for scalable computing performance. The ACM-XD15MT is perfect for space-constrained systems requiring increased density and reduced power consumption such as virtualization, edge computing or other industrial applications. The ACM-XD15MT is an Intel® Xeon® D processor-based
ACROSSER ACM-XD15MT COM EXPRESS TYPE 7 MODULE IS RELEASED Continue Reading
Summary: I designed an electric load. Using an Arduino Nano, the load can be programmed, and the voltage and current are measured. You can set a constant current (CC), a constant power (CP), or a constant resistance (CR) load by simply typing it in to the Arduino Serial Monitor. The circuit is designed for up to 30V, 5A, and 15W. An opamp, a
Arduino based programmable load Continue Reading
Isabellenhütte has developed a new range of precision resistors in standard sizes with resistances ranging from 1 to 6 mOhm for applications which require small and low-ohmic shunts. In terms of their construction, the components are also less complex than the current ISA-PLAN®resistance families. And yet, they offer the same performance quality: very good long-term
The inspiration for this project started when I saw a variety of awesome stereo LED towers on YouTube (also referred to as VU meters). Many of the videos showed the end result, and maybe a slideshow of the assembly process, but lacked complete build details or a circuit diagram. So, I set out to find
