Open Source Hardware - OSHW Draft Definition

OSHW Draft Definition 0.3 is based on the Open Source Definition for Open Source Software and draft OSHW definition 0.2, further incorporating ideas from the TAPR Open Hardware License.

Open Source Hardware - OSHW Draft Definition

Open Source Hardware (OSHW) is a term for tangible artifacts - machines, devices, or other physical things - whose design has been released to the public in such a way that anyone can make, modify, distribute, and use those things.

Open Source Hardware - OSHW Draft Definition

Open source hardware is hardware whose design is made publicly available so that anyone can study, modify, distribute, make, and sell the design or hardware based on that design. The hardware's source, the design from which it is made, is available in the preferred format for making modifications to it. Ideally, open source hardware uses readily-available components and materials, standard processes, open infrastructure, unrestricted content, and open-source design tools to maximize the ability of individuals to make and use hardware.

Adapteva - Andreas Olofsson at OHS

Making parallel computing easy to use has been described as “a problem as hard as any that computer science has faced”. With such big challenges ahead, we need to make sure that every programmer has access to cheap and open parallel hardware and development tools.

Open source hardware gives people the freedom to control their technology while sharing knowledge and encouraging commerce through the open exchange of designs.

Learn about Solid State Relays - SSR

They are called SSR as there are made of semiconductors and have no moving parts to wear out. They do generate heat depending on load and switching. Thyristors are used in most as they are rugged, mosfets and IGBT may also be used for various applications.

Solid State Relays - SSR

In this section you will find SSR designs and PCB layouts which you can study. These were made and sold by me years ago. So the PCB layouts have gone thru some revisions and they worked quite well.

 Learn about Solid State Relays - SSR
Applications -

Many machines and equipment use some SSRs in their products which may need replacement. So the SSR is not only sold to OEMs but also to Service-Maintenance Market. These are also modified as Output Modules for digital outputs coming from embedded systems or Computers.

Electromagnetic Relays - 

NO - Normally Open - when the relay is not energized or activated, this terminal is open-circuit.

NC - Normally Closed - when the relay is not energized or activated, this terminal is closed circuit.

COM - The Common Center Terminal in relays. This is the center terminal that closes circuit with NC-NO.

The terminals are potential free and floating and are insulated from the control signals or coil windings by many kilo volts. Many provide visible isolation. These terms apply to SSR or Big Contacters too.

    System-on-Chip - SoC - IP

    When a product has to be made small, the board real estate is limited or it has to be manufactured in large numbers.... SoC is the Answer. A Microprocessor evolved into a Microcontroller by packing many external chips into one chip. Now uC Card along with the other blocks like A-D, Port Drivers, Networking elements, Display Driver and other peripherals can be packed into one chip.

    Some Power Supply and RF blocks cannot be easily added inside as they have a silicon processing more specific to their applications. Laser trimmed Instrumentation Op-Amps, high accuracy resistor arrays, high value capacitors, magnetics and supporting chips are placed outside on the PCB.

    The SOC can pack Digital Chips, Memory, A/D, D/A converters, uC, RAM and Custom programmable areas. For more specialized communications, analog and power requirements; Special SoC types can tackle RF and Power management within a chip because of proprietary silicon processing expertise.

    System on a chip - Wiki

    "A system on a chip or system on chip (SoC or SOC) is an integrated circuit (IC) that integrates all components of a computer or other electronic system into a single chip. It may contain digital, analog, mixed-signal, and often radio-frequency functions—all on a single chip substrate. A typical application is in the area of embedded systems."

    System-on-Chip - SoC - IP

    Programmable SoC offers an alternative to custom ASIC as you can make different products from the same chip, yet make products that are portable and low power. The software, pcb, user interface and support components has to be redesigned for every unique product. Many standard IPs are available for Design and Reuse.

    Electric Double Layer Capacitor - EDLC

    The Electric double layer capacitor has the main use of a Charge Reservoir. That means a large amount of electrical charge in a small footprint.

    These charge/discharge quickly unlike the battery, There is no Electrical Energy to Chemical Energy Transformation and back, like in batteries. It may need caution in design and usage as they may carry a lot of punch.

    Also known as Ultracap, Goldcap, Supercap - Electric double layer capacitor, In Farads, like batteries, Energy Reservoirs or eFlywheel.

    Electric Double Layer Capacitor - EDLC

    In Product Safety terms; The Battery has a Internal Resistance, but a Supercap does not. When used in Values like 100F and is fully charged, an Internal or External Breakdown of Insulation or Short Circuit may Occur. The Heat Generated is Enormous. Murphy's Law says such things happen..

    Supercap at Wikipedia - Electric Double Layer Capacitor (EDLC) or SuperCapacitor

    DLCAP - Electric Double Layer Capacitor - Nippon - They have a range of Supercapacitors upto 2500F at 2.5V and Modules like 400F and 15V. There are two types Prismatic and Cylindrical. In comparison to batteries - multi-million cycles of charge-discharge is possible.

    EverCAP - Double Layer Capacitors - Nichicon - They have two types, High Power Density for a large current discharge. High Energy Density for a long backup time. Over a million Charge/Discharge cycles. High Efficiency. Capable of fully discharging to zero volts.

    Some things to note for a design engineer. The EDLC or Electric Double Layer Capacitors ...
    • Specified Endurance and end of life.
    • Excess Vibration can alter Specs.
    • Caution - The maximum temperature.
    • Specs are dependent on Temperature.
    • Maintain Low ripple current on Charge/Discharge.
    • It is Polarized like a Electrolytic cap.
    • Not Hot parts or Heatsink near cap.
    The Double Layer Capacitors developed by WIMA are storage capacitors with highest capacitance values in the Farad range.

    GTO Capacitors - WIMA - They are among others suited to serve as batteries, can deliver considerably higher currents for a short time, however, and are maintenance free.

    SuperCapacitors - WIMA - These EDLC supercap has one-tenth of energy, but delivers over 10 times of power due to ultra low ESR. In Comparison with a Battery. A Lifetime of over 500,000 cycles.

    Xelled Supercapacitor - Vinatech - Hy-Cap is an energy storage device that stores instantly a  large volume of electric energy and supplies instantly or  continuously higher current, by the mechanism of  absorbing and de-absorbing electric charge.

    Reference -
    Manufacturers -

    Electric double-layer capacitors ELNA - The electric double-layer design does not have the solid dielectric that is used in the previous designs, nor does it have the chemical reactions such as are found in batteries during charging and discharging. Rather this design has the following characteristics:

    RUBYCON - EDLC Supercaps - Electric double layer capacitor (EDLC) stores the electrode surface and the interface of the electro bath as a dielectric substance at the part called “electric double layer”
    EDLC has feature that is not electrochemical reaction, whereby rapid electrical charge and discharge is possible and have longer lifecycle.

    "In Germany one finds this designation now and then for an electrician on the work. Particularly in the winter, if it is still dark in the morning, one often sees "Strippenstrolche" with its building lamp on the building site:"

    Combination of Rain and Sun Harvesting
     
    "The inspiration for a self-sufficient toilet flush was now close at hand: I thought at first to work with a power supply that provides me the 12V to the pump. But as a power supply would idle constantly consume energy, I rejected this solution. I have long experimented with solar power, so I decided, now a solar system for our toilets to build. On the flat roof of our garage I installed two 12V - 55Wp - solar - modules (Conrad Electronics). This I switched in parallel."

    "As a solar storage currently serves an ordinary car battery 45Ah (later 3 pieces with a total of 135 Ah). The charging control acquires an 8A charge controller (Conrad). So all very simple."

    MAX8881 and DS2490 Characterization for Cells

    Rechargeable AA cells are very popular for a large variety of portable applications. The number of brands is also high, and the cell quality can differ considerably. Cell capacity is sometimes different from that specified, and the capacity often deteriorates dramatically after a limited number of discharge cycles. ....

    See Maxim Application Note - Simple Characterization Circuit for Rechargeable AA Cells

    This characterization circuit, plus a PC and some software, accurately measures the full discharge cycle for a rechargeable AA cell. Cell capacity and output resistance can easily be determined from the curve resulting from these measurements.

    MAX8881 and DS2490 Characterization for Cells

    In Figure 1, the simple circuit is connected to the USB port of a PC. No external power source is required because power is extracted from the USB bus voltage. U1 (DS9490R) is a USB dongle that converts the USB protocol to the 1-Wire® protocol, thereby allowing the PC to communicate with the key circuit component (U2).
