The solder matters, it is an undisputable fact confirmed daily in a development and production of electronics. Hand soldering of prototypes, automated machine soldering, soldering of small SMT components or on the in contrast soldering of big joints of massive connectors, rework, … all that wants a solder optimized for a given usage. As we […]
PORTLAND, Oregon — Scientists trying to fulfill the 80-year-old dream of Nobel laureate Eugene Wigner, recently discovered how to place crystalline lattices of pure electrons in the bottom of a silicon-encased quantum well. The resulting material promises electron mobility more than 200 times greater than that of graphene and more than 1,700 times that of
Kirlian photography is an interesting photographic technique of capturing corona discharge of objects. The images basically contain only edges in a form of blue glow. Note: one of those photos is visible in “The X files” intro – read the whole article to know why! In this post I will present my minimalist approach with
Kirlian photography – a simple way of taking it Continue Reading
Aakar Brainboard v2 is a modular CNC controller board based on LPC1768/69 Cortex-M3 chip. Due to its modular design it allows easier upgrades as per requirements and easy replacement if there is any broken part. It runs on open source Smoothie modular firmware and is targeted at 3D Printers, Laser cutters, CNC Mills, Pick and
The dominant technology for today’s high-brightness LEDs is gallium nitride (GaN) on sapphire, silicon carbide (SiC), or silicon-substrate LEDs. These materials are popular because the resultant LEDs are bright, efficient, and last a long time. However, the chips are tough to manufacture and package into useable devices, multiplying the cost of end products that use
Improved Silicon-Substrate LEDs Address High Solid-State Lighting Costs Continue Reading
Texas Instruments has launched the MSP-432, a Cortex-M-based microcontroller that aims at providing developers with a higher-performance upgrade path for MSP-430 users while still retaining low-power operation. The 32-bit processor uses an M4F core with FPU and DSP extensions, achieving a CoreMark score of 3.41/MHz and a certified ULPBench score of 167.4, among the highest
In semiconductor and electronics industry, a diode is a widely used discrete component. It is a significant element in many electronic circuits and applications ranging from low power signal circuits to power rectification. Based on the functions and ratings, there are different types of diodes. However, all semiconductor diodes contain a PN junction to perform
I am scatterbrained. I like to drink hot tea. Oversteeped tea gets bitter. I am easily distracted. The natural choice was to (over)engineer something with inexpensive hobby-grade electronics. Automatic tea timers are hardly new and people have made them from discarded toasters and K’Nex which I have a lot of respect for. People on this
This description could start by a long list of technical improvements of Panasonic batteries. thanks to which they gained a stable place on the top of development in this segment (AGM, expanded positive grid. additives for regeneration from a deep discharge, self-extinguishing container material,…). However those are things, which can be easily checked up from
Maintenance-free lead batteries Panasonic will surprise by their lifetime Continue Reading
In the last 14 years, the Universal Serial Bus (USB) has become the standard interface to connect devices to a computer. Whether it’s an external hard drive, a camera, the mouse, a printer, or a scanner, the physical connection to transfer data between devices generally is a USB cable. The interface is indeed universal. USB
