Sun Equipment Corporation - Training Systems

Kits and Custom Equipment Developer/Provider for Training and Industry, Engineering design and Development Lab Support.

Sun Equipment Corporation - Training Systems

GSE-40106 Green Solar Energy Trainer is a basic green energy transduction kit for solar power. It is equiped with a MCU forusers to learn and observe the Maximum Power Point Tracking (MPPT) algorithm. Variations of the MMPT algorithm allow users to experiment with the regeneration of green energy.

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.

Mechatronics Demonstration Kit with PIC

The DM163029 or PICDEM Mechatronics demonstration board is an easy-to-use mechatronics development and demonstration platform. Mechatronics refers to implementing intelligent control in a mechanical system.

Mechatronics Demonstration Kit with PIC

The demonstration kit takes a hands-on approach to learning about mechatronics. Jumper wires are provided in the kit which allow the developer to experiment with connecting the PIC microcontroller to various components on the board. These components include sensors, LEDs, human input devices and motor drivers.

Mechatronics Demonstration Kit with PIC

Features Include
  • PIC16F917 MCU with 8 MHz
  • Displays: 8 LEDs and LCD
  • Stepper motor and brushed DC motors
  • Analog temperature sensor
  • 32.768 kHz crystal for time generation
  • Human inputs: 4 tactile switches, 2 potentiometers
  • Optical speed sensor for brushed DC motor
  • ICSP programming capability - MPLAB ICD

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.

CadSoft EAGLE Layout Editor - Autodesk

The EAGLE Layout Editor is an easy to use, yet powerful tool for designing printed circuit boards (PCBs). EAGLE offers the three modules: Schematic-Editor, Layout Editor and Autorouter embedded on one single interface.

 CadSoft Computer GmbH created Eagle. The company was acquired by Autodesk Inc. in 2016

CadSoft EAGLE Layout Editor

EAGLE is easy to learn, easy to use and easy to buy. It runs on Linux, Mac and Windows and allows feature enhancement, such as simulation, 3D-visualization, data import and export and self defined commands, through User Language Programs (ULP’s) which are partly integrated in EAGLE 

CadSoft EAGLE Layout Editor - Autodesk

The name EAGLE is an acronym, which stands for .

Easily Applicable Graphical Layout Editor.

The program consists of three main modules, Layout Editor, Schematic Editor and Autorouter. These are embedded in a single user interface. Therefore there is no need for converting netlists between schematics and layouts.
