Laserloper EURORACK. Frankenstein, a vacuum tube home theater system. Visualist, '70s Video Effects. Kalman filter. The Kalman filter keeps track of the estimated state of the system and the variance or uncertainty of the estimate.
The estimate is updated using a state transition model and measurements. Arduino PCR (thermal cycler) for under $85. This tutorial will show you how to make a thermal cycler from scratch for about $85. In short, PCR (polymerase chain reaction) amplifies bits of DNA, creating millions of copies of a target sequence. You can use it to test a DNA sample for a specific gene, for instance, to check for genetic modification in food and for hereditary gene testing. During PCR, a mixture of DNA, primer and DNA polymerase is cycled between three different temperature settings, over and over again. This project uses an arduino to control two high-power resistors to heat up the sample, a computer fan to cool down, and a thermocouple to keep track of the temperature. The design supports two samples at a time, though it could probably be extended to support more.

I am re-visiting the field of homemade electrophysiology equipment, and although I’ve already published a home made electocardiograph (ECG), I wish to revisit that project and make it much more elegant, while also planning for a pulse oximeter, an electroencephalograph (EEG), and an electrogastrogram (EGG). This project is divided into 3 major components: the low-noise microvoltage amplifier, a digital analog to digital converter with PC connectivity, and software to display and analyze the traces. ADC without ADC. Digital electronics and Analog electronics doesn't mix easily.
Butterworth Low-Pass Filter. DESIGN OF a 5th ORDER BUTTERWORTH LOW-PASS FILTER USING SALLEN & KEY CIRCUIT Background Theory: Filters are classified according to the functions that they are to perform, in terms of ranges of frequencies.
We will be dealing with the low-pass filter, which has the property that low-frequency excitation signal components down to and including direct current, are transmitted, while high-frequency components, up to and including infinite ones are blocked. The range of low frequencies, which are passed, is called the pass band or the bandwidth of the filter. It extends from ω=0 to ω= ωc rad/sec (fc in Hz). The ideal response of a low-pass filter is shown above. Bell System Technical Journal, 1922-1983. Electronic Circuits and Design Information.
Operational Amplifier Low Pass Filter Circuit. Block I Apollo Guidance Computer (AGC): How to build one in your basement. Super Precision Gyroscope (without gimbals) - From Gyroscope.com. The Super Precision Gyroscope has been designed and built to the highest precision from the very start, made from solid brass with a light-weight aluminium frame.
Carefully chosen stainless-steel miniature ball bearings allow it to run smoothly and almost silently for an amazingly long time. The gyroscope comes with a number of attachments allowing numerous configurations to perform scientific, educational or simply mesmerising experiments. The gyroscope comes with 2 x 50 mm long stainless steel extension rods, 2 x ball ends, 1 x slotted end. Photos. Electrostatic Machines. Electrostatic machines are electromechanical devices that produce "static electricity", or electricity at continuous (DC) high voltage.
They were fundamental in the early studies about electricity, started in the XVII century, in the form of "friction machines", and their development culminated at the end of the XIX century with the development of powerful "influence machines". Today, some specialized uses for them continue to exist, but they are mostly seen as demonstration devices in physics laboratories, with much of their history forgotten.

Information sources about how to build your own Tesla Coil. Tesla Coils) Stoneridge Engineering - Theory of Operation of the Quarter Shrinker. Theory of Operation: The Quarter Shrinker uses a technique called high-velocity electromagnetic forming , also known as "Magneforming" or magnetic pulse forming. This is a "high energy rate" metal forming process that was originally developed by the aerospace industry in conjunction with NASA, and was commercialized by Aerovox , Grumman , and Maxwell Technologies (now a part of General Atomics ). High energy rate processes apply a large amount of energy into a workpiece during a very short interval of time. The approach uses pulsed power , quickly discharging a high energy capacitor bank through a coil of wire to generate a brief, extremely powerful, rapidly changing magnetic field which then "forms" (reshapes) the coin.
Are you sure about that 60Hz? For the past few weeks, I've been blogging my assembly of the transistor clock which is now hanging on the wall of my new apartment.
