In this instructable I’m going to show you how to make your own PIC18 development board that features both Ethernet and Full Speed USB 2.0 at a low cost. Features: The development board is based on a PIC18LF4553 microcontroller. The microcontroller features a Full Speed USB 2.0 (12Mbit/s) interface without the need for any external […]

In some previous posts I talked about getting an x-ray head working, reverse engineering an x-ray sensor, and working with LinuxCNC. In this post I put them all together so that I can take a bunch of x-ray snapshots across an entire PCB. This allows me to more quickly reverse engineer PCBs. Problem: with my
I published this schematic long ago in this article: Adjustable power supply and since then I made some improvements in PCB to make the board as small as possible. The idea is to be easy to attach the whole board to the heat sink which we want to monitor. The board is only 27mm x
Ready for sampling in September, Toshiba’s 48-layer BiCS (Bit Cost Scalable) flash memory stores 256 Gbits using a 3-D vertically stacked cell structure and 3-bit-per-cell triple-level cell technology. By employing this 48-layer vertical stacking process, BiCS flash surpasses the capacity of conventional 2-D NAND flash memory, where cells are arrayed in a planar direction on

Hey folks! After making an Arduino smartwatch just last week, I received many complaints,or tips, to use a RTC (real-time clock) module. That’s because the Arduino timer is not very precise, it can lose a couple a minutes along a full work day. Luckly, I had one of those modules at my home, I decided
It was a few years ago that I first heard of a free site where you could draw and simulate designs. “What’s the point?” I thought. But, the idea is taking off. Was I wrong? I questioned the usefulness of this cloud concept because there had already long existed good, free circuit simulators. A quick
Using a hybrid silica sol-gel material and self-assembled monolayers of a common fatty acid, researchers have developed a new capacitor dielectric material that provides an electrical energy storage capacity rivaling certain batteries, with both a high energy density and high power density. If the material can be scaled up from laboratory samples, devices made from

If you dig around in your camera’s settings long enough, you’re almost assured to find that it has a mode to create time-lapse videos — those magical, time compressing movies that can turn any hillside or street corner into a lightning-paced dreamscape. Time-lapse videos by themselves are easy enough to make, but if you do

Good soldering station is usually a fundament of a workplace. Desoldering station is usually a necessity if you work in development or service. And a hot-air station? – this one is becoming a must at any development or rework of PCBs with SMT components. If we already know, that it´s ideal to have all these
WXR3031 rework station will replace you three devices Continue Reading
PORTLAND, Ore.–Purdue University researchers have demonstrated a CMOS-compatible all-optical transistor capable of 4THz speeds, potentially over a 1000 times faster than silicon transistors. Nano-photonic transistors processed at low-temperatures can be fabricated atop complementary metal oxide semiconductors (CMOS) to boost switching time by ~5,000-times less than 300 femtoseconds (fs) or almost 4 terahertz (THz), according to
