Exposing PCBs with a home made laser printer. Making your own printed circuit boards – as useful as it is – is a pain.
Using the very popular toner transfer method requires a dozen steps that have to go perfectly the first time, and milling boards on a CNC machine creates a lot of mess. The most industrious hackers are able to bodge up a direct-to-board printer from an old inkjet printer, but these builds are usually a little kludgy. [Tixiv]’s LaserExposer board printer is one of the first builds we’ve seen that does away with all the negatives of the other techniques of PCB manufacturing and turns making your own boards into a very, very simple process.
The LaserExposer uses photosensitive copper board, like many of the other PCB printers we’ve seen. Nixie-clock. FPGA programming step by step. FPGAs and microprocessors are more similar than you may think.
Here's a primer on how to program an FPGA and some reasons why you'd want to. Small processors are, by far, the largest selling class of computers and form the basis of many embedded systems. The first single-chip microprocessors contained approximately 10,000 gates of logic and 10,000 bits of memory. Today, field programmable gate arrays (FPGAs) provide single chips approaching 10 million gates of logic and 10 million bits of memory. Figure 1 compares one of these microprocessors with an FPGA. Powerful tools exist to program these powerful chips. Learning FPGA And Verilog A Beginner's Guide - Introduction. Introduction.

Copyright Tomi Engdahl 1997,2000,2005 Preface Telephone circuit gain always interrest, because telephones are everywhere and quite often there are old telephone luying around somewhere.
Those telephones can be used for many interresting experiments including small home intercom: connect telephones in series or parallel and feed suitable operating current (about 20 mA) to them through resistor from power supply. Telephone Interface (updated 12/30/09) This project describes an Arduino/MCU interface to a telephone land-line. It's only been tested on a US version of the telephone system, but hopefully it will apply to the phone system in other countries. The basic idea was to allow the MCU to make calls by transmitting DTMF tones, and to receive and decode DTMF tones (keystrokes) made on the phone that was called. There are other possibilities however. Using the complete interface, it should be possible for the MCU to answer calls, and to transmit "room sounds" picked up by a microphone to the other phone. If you're only interested in sending and receiving DTMF tones and not interfacing to a phone line, you can skip the next dozen or so paragraphs.
It all begins with the interface to the actual telephone line. There are two reasons for this: Phone lines require a 600 Ohm "balanced line". My Nixie Clock Project. My Nixie Clock Project by Peter H. Wendt Rel. 0.9.5_en, Last Update: Wednesday, 2009-11-18 Most common question: "Your what Clock Project ? " Before Light-Emitting Diodes (LEDs) and Liquid Crystal Displays (LCDs) the electronic industry used cold-cathode tubes for displaying numbers, symbols and even characters. Even though they are called "tubes" they differ from "radio tubes" by having no heater wire to heat the cathode - and therefore run much colder. A Dozen Ways to Measure Fluid Level and How They Work. December 1, 2004By: Kevin Hambrice, K-TEK Corp., Henry Hopper, K-TEK Corp. The demands of sophisticated automated processing systems, the need for ever-tighter process control, and an increasingly stringent regulatory environment drive process engineers to seek more precise and reliable level measurement systems.
Improved level measurement accuracy makes it possible to reduce chemical-process variability, resulting in higher product quality, reduced cost, and less waste. Regulations, especially those governing electronic records, set stringent requirements for accuracy, reliability, and electronic reporting. The newer level measurement technologies help meet these requirements. Arduino Nixie Clock > Pics & Source Code. SMD Soldering Practice Kit.
La fotoincisione dei circuiti stampati. 9 Degrees of Freedom - MPU-9150 Breakout. Description: The 9DOF MPU-9150 is the world’s first 9-axis MotionTracking MEMS device designed for the low power, low cost, and high performance requirements of consumer electronics equipment including smartphones, tablets and wearable sensors. And guess what? You get to play with it. This breakout board makes it easy to prototype with the InvenSense MPU-9150 by breaking out all the pins you need to standard 0.1" spaced headers.
The board also provides I2C pullup resistors and a solder jumper to switch the I2C address of the device. Processing - MPU-9250. The MPU-9x50™ family of parts are the world’s first 9-axis MotionTracking devices designed for battery operated, high performance consumer electronics products. The 9-axis product family incorporates the same market proven MotionFusion™ and run-time calibration firmware that is supported in InvenSense’s market leading MPU-6000 and MPU-3000 family of products. This firmware has shipped in millions of units and has been very well market validated. 9-Axis MotionTracking has become a key function in many consumer electronics devices including smartphones, tablets, gaming consoles, and smart-TVs.
The size advantage of the integrated 9 axis devices versus a discrete solution is compelling for space constrained products such as smartphones and wearable sensors.

Several months ago, I was approached by the Portland band Starfucker (STRFKR) to build them an LED video wall for their upcoming tour. It needed to be large, bright, and durable, but also lightweight, portable, and easy to set up and tear down. They wanted to be able to plug in an iPod or iPad and play videos that are synced up along with their click track so everything goes along perfectly with the music. I enlisted the help of Alex Norman to take care of the software side of the project, and got to work trying to figure this thing out.
