Memristor is a name of passive two-terminal circuit elements in which there is a functional relationship between charge and magnetic flux linkage. A Memristor could be used to replace the Transistor within devices such as memory, CPU devices, and because of the nonvolatile nature, (do not lose stored data when switched off), Solid State Hard drives. It has been stated that these Memristors could lead to new designs of computers. They may be able to be used in an analogue way that mimics the human brain. They could , of course, also be used in other devices. The Memristor term is short for memory resistor. Memristor chips require less energy to operate than current alternatives, such as flash memory. They also store data in approximately half the space required by flash chips and are virtually immune to interference from radiation – making them attractive to any manufacturer looking to create ever-smaller but ever-more-powerful devices. A Memistor is the fourth passive device predicted by Prof. Leon Chua in 1971: the resistor, the capacitor, and the inductor and now the Memistor.

Soundcard Osicilloscope  

Sound Card Oscilloscope.

The PC based Soundcard Oscilloscope receives its data from the Soundcard with 44.1kHz and 16 Bit resolution. The data source can be selected in the Windows mixer (Microphone, Line-In or Wave). The frequency range depends on the sound card, but 20-20000Hz should be possible with all modern cards. The low frequency end is limited by the AC coupling of the line-in signal. Be aware, that most microphone inputs are only mono. The oscilloscope contains in addition a signal generator for 2 channels for Sine, Square, Triangular and Sawtooth wave forms in the frequency range from 0 to 20kHz. These signals are available at the speaker output of the sound card. These can be fed back to the oscillocope in order to generate Lissajous figures in the x-y mode.

  • Trigger modes: off, automatic, normal and single shot
  • Triggerlevel can be set with the mouse
  • The signals of the two channels can be added, subtracted and multiplied
  • x-y mode
  • Frequency analysis (Fourier spectrum)
  • Frequency filter: low-, high- and band-pass
  • Cursors to measure amplitude, time and frequency in the main window
  • Audio Recorder to save data to a wave file
  • For multi soundcard system, the used card can be selected in the settings tab

DipTrace Free An advanced PCB design software application that consists of 4 modules: PCB Layout with high-class auto-router and 3D PCB Preview, Schematic Capture, Component and Pattern Editors that allow you to design your own component libraries. Besides being very simple to learn, this software has a very intuitive user interface and many innovative features. For instance, a schematic can be converted to a PCB with one mouse click. Advanced manual placement and auto-placement features allow to get acceptable placement in several minutes. The board designer can instantly renew the PCB from an updated version of schematic and keep all previous work without changes. PCB and Schematic can be compared at any design stage to ensure they are identical. Hierarchical and multi-sheet schematics are supported. DipTrace has a powerful automatic router. It can route a single layer and multilayer circuit boards, and there is an option to autoroute a single layer board with jumper wires, if required. DipTrace also provides you with external autorouter support. Smart manual routing tools allow users to finalize the design and to get the results they want in a blink of an eye. Accurate shape-based copper pour system with different possible fill types and thermals is available. Other important features are Electrical Rule Check (ERC), Design Rule Check (DRC) and Net Connectivity Check - the functions that check connections in Schematic by different rules (pin type, short circuit, etc.), the clearance between layout objects, which ensures board accuracy, and connectivity of all nets not depending on how they are connected (with traces, thermals or shapes). DipTrace modules allow you to exchange schematics, layouts and libraries with other EDA and CAD packages. DipTrace Schematic Capture and PCB Layout also support popular netlist formats and spice. Output formats are DXF, Gerber, Drill and G-code. Standard libraries include 100.000+ components

World's first transistor    

World's first transistor

Dec. 16, 1947, three physicists at Bell Laboratories in Murray Hill, N.J., built the world's first transistor. William Shockley, John Bardeen and William Brattain had been looking for a semiconductor amplifier to take the place of the vacuum tubes that made radios and other electronics so impossibly bulky, hot and power hungry. They were so instantly certain they'd found their answer that they didn't speak a word of it to anyone for six months, until they could experiment further and apply for patents. Then on June 30, 1948, they held a press conference in New York City. They showed the world not only a big model of a transistor but also a TV and a radio with transistors in place of the tubes. Nobody was talking about anything like computers yet, but it was a first look at the future we all live in. The world's response? The New York Times ran an item at the bottom of its "News of Radio" column on page 46.

Understanding electricity (water analogy) Beginner overview of electricity, using the water analogy... What do you think?

Electricity seems very difficult for most people to understand. You can't properly see it, you can't properly feel it and you can't taste it or smell it so what is it? It travels quite well through metals and generally poorly through non-metals. It doesn't behave quite like anything else.

But this is not quite true: fluid flowing through a system of pipes can behave in many respects like electricity flowing in a circuit. The 'obvious' exception to this is that if you pierce a pipe full of water, the water comes out.

The main difference is that water will fill any space whereas electricity will 'fill' only a conductor. Yes - the analogy is not perfect, but it is helpful and understanding will come not only from the similarities but also from the differences.

New Coating Turns Nanotubes Into Dense, Strong Batteries

A blazing coating lets microscopic carbon nanotubes generate electricity

Engineers at MIT have devised what they call a new way of producing electricity. By coating a microscopic carbon nanotube with a layer of fuel and igniting one end with a spark or laser, they're able to send a wave of heat shooting through the nanotube's interior.

This thermal wave pushes electrons in its path, generating a significant electric current. Prototypes already have energy density 100 times greater than lithium-ion batteries, and they can be stored indefinitely without leaking charge. The researchers are now investigating optimal fuels and, to make the system reusable, will have to invent a way to automatically apply a fresh layer of fuel after the first burns away.

How It Works:
1. Heat the Tube. One end of a microscopic carbon nanotube, coated with reactive fuel, is ignited by a laser.
2. Herd the Particles. A wave of heat races through the inside of the tube, pushing electrons toward the other end.
3. Harvest the Energy. The movement of the electrons forms an electric current.

RepRap Mendel prints etch resist   Ultimachine YouTube Channel    
 

A video highlighting our experiment using a Sharpie marker on Mendel to print etch resist and make it's own circuit boards.

The marker tip is ~0.7mm. We are reliably printing 0.7mm traces with 0.6mm clearance. Printing the resist took about 1 hour per coat.

Feedrates could easily have been higher. Two coats is giving effective etch resist. We etched with MG ferric chloride acid* outside in 80 something F and it took about 20 minutes.

After etching we washed the board with water to stop the process and removed the marker residue with acetone.

Then off to the drill press for the tons of holes (I think drilling should have been done by Mendel too). This is in no way a substitute for spoolhead or other needed RepRap circuit technologies that are in the works by other RepRappers, but it works, and...  Yeah!

How to reverse engineer a schematic from a circuit board. This project is a result of needing to service a domestic electronic item without being able to obtain a circuit diagram. The process proved to be very long and painstaking, but also very rewarding.  The steps presented here are not exact, and you will no doubt find your own way of working which is more effective in the case of any particular board.  However, the basic procedure is essentially correct for the majority of boards which are too complex to reliably hand trace. Without the need to invent the process, things should progress more quickly.
