SCIENTIFIC-75025 -- Wind Up Power Generator Set -- US$55.00

This new Wind Up Power Generator Set allows you to experience Green energy firsthand. You create your own electricity by simply turning the generator's handle which puts the electricity producing motor into action, making batteries not required. By winding the handle for approximately 30 or more seconds, the rechargeable car runs more than a minute.

  • This is an assembly kit.
  • Length of clear orange rechargeable car and generator: 122mm.
  • Comes with special stickers.
  • The generator unit has a gear ratio of 38.2.1.
  • No cement required for assembly.

 

SCIENTIFIC-ETH-RELAY-MODULE-8 -- 8-channel Ethernet relay module -- US$120.00

Controlled from over Ethernet using simple TCP/IP commands.

Full ETH-RLY16 Documentation


Number of Relay's - 8
Power - 12V DC adaptor, supplied separately.
Control interface - HTTP (webpage) or TCP/IP over Ethernet.
Relay current - Up to 16Amp @24vdc or 250vac
Connections - Screw Terminals for N/O N/C and Common contacts.

 

SCIENTIFIC-USB-RELAY-MODULE-2 -- 2-channel USB relay module -- US$53.00

The USB-RLY02 provides two SPCO (Single Pole Change Over) volt free contact relay outputs with a current rating of up to 16A. Device power comes from the USB connection and does not require any additional sources. The normally open, normally closed and common relay pins are all available on the screw terminals.

The USB-RLY02 module uses the Microchip PIC24FJ32GB002 to handle all the USB protocols.  Before using the USB-RLY02, you will need to download the Devantech inf files and unzip them into a temporary folder.  Installation instructions are available at Devantech technical documentation page.  The USB-RLY02 will show up on a Apple computer as a virtual serial port without the need to install any drivers.

 

SCIENTIFIC-USB-RELAY-MODULE-8 -- 8-channel USB relay module -- US$95.00

The RLY08 provides 8 volt free contact relay outputs with a current rating of up to 1 Amp each. It is powered from the USB bus and has an exceptionally low maximum current consumption of approx. 90mA with all relays on. The relays are SPCO (Single Pole Change Over) types. The normally open, normally closed and common pins are all available on the screw terminals. Here are the technical specifictions

 

SCIENTIFIC-USB-RELAY-MODULE-16 -- 16-channel USB relay module -- US$128.00

The USB-RLY16 provides eight volt free contact relay outputs with a current rating of up to 16Amp each. The processor is powered and instructed from any standard USB bus and the relay power is obtained by the DC power input adaptor. The DC input jack is 2.1mm with positive core polarity, DC supplies are required to supply at least 500mA at 12vdc. The relays are SPCO (Single Pole Change Over) types. The normally open, normally closed and common pins are all available on the screw terminals. Here are the technical specifictions

 

SCIENTIFIC-I2C-SERIAL-RELAY-MODULE-8 --8-channel I2C and serial relay module -- US$78.00

RLY08 provides 8 volt free contact relay outputs with a current rating of up to 1 Amp each. It requires a 5v supply and has an exceptionally low maximum current consumption of approx. 100mA with all relays on. The relays are SPCO (Single Pole Change Over) types. The normally open, normally closed and common pins are all available on the screw terminals. Here are the technical specifictions and dimension.

 

SCIENTIFIC-INVERTED-PENDULUM -- Inverted Pendulum experiment complete system -- US$6,599.95

An Inverted Pendulum is an inherently unstable system. Force must be properly applied to keep the system intact. To achieve this, proper control theory is required. The Inverted Pendulum is essential in the evaluating and comparing of various control theories.This kit comes with all hardware and software for develop and analyze different digitial control theories. Technical specification and product details.

 

SCIENTIFIC-ELECTRIC BELL -- Electric Bell / Buzzer / Telegraph Key Constructions kit -- US$29.00

The objective of building the electric bell is to understand the nature of Electro-magnetism. The kit is changeable into three constructions: Electric Bell, Buzzer, and Telegraph Key. Instructions are included. Made in Japan by Daiwa Scientific and Educational.

 

SCIENTIFIC-MOTOR -- DC Motor Constructions kit -- US$29.00

The objective of the kit is to understand the difference between the permanent magnet and the electro-magnet, and also learn the principles of electric motors. Instructions are included. Made in Japan by Daiwa Scientific and Educational.

 

SCIENTIFIC-PRACTICAL BELL -- Practical Bell Constructions kit -- US$29.00

The objective of the kit is to perform Electro-magnetic experiment and mechanisms of the bell. The bell can be used as a housebell. Instructions are included. Made in Japan by Daiwa Scientific and Educational.

 

SCIENTIFIC-75021 -- Wind power generator kit -- US$65.00

This new educational kit lets you explore the mechanisms involved in harnessing the alternative energy of wind power. The windmill features loop-wing design that can be rotated by the slightest breeze. You can also run while holding it to generate wind artificially. The kit comes with a rechargeable vehicle that uses power generated by the windmill, running for 1-2 minutes for each 5-10 minute of charge.

About the Model

  • Special "loop wing" design secures high efficiency in power generation, by ensuring that even a minimum amount of wind will produce quick rotation of windmill.
  • 2 types of gears allow choice of double gear for light wind, and triple gear for stong wind, improving power generated by motor depending on wind strength.
  • Base doubles as handle allowing you to run while holding windmill to generate power
  • Low-friction connectors to ensure smooth rotation by wind & efficient power generation
