  • Breadboard Basics

    When working on electronics, a breadboard is one of the most important items in your prototyping toolbox. 

    What is a Breadboard?

    A breadboard is a rectangular plastic box filled with holes, used to test circuits.

    No soldering is actually done on the breadboards, but instead they are used to prototype circuits by poking wires and components through little contact holes to form a complete circuit. Continue reading

  • New Tech Makes Circuit Board That is 90% Recyclable

    Electronic waste is becoming more of a troubling problem with the global volume of electronic waste expected to grow by 33% in the next four years. According to the UN’s ‘Step initiative’ nearly 50m tonnes of e-waste was generated worldwide last year, about 7kg for every person on the planet, as old devices were discarded to sit in landfills.

    Even when devices are recycled responsibly, circuit boards in everyday electronics are based on reinforced epoxy glass and solder, which makes it hard for them to be taken apart safely. Continue reading

  • Power Supplies - the difference between switch mode and linear.

    There are considerable differences between linear and switch mode power supplies.

    We stock both designs in our bench power supply range. Here is a handy table to provide you with an overview of the main differences:



    Switching / Switch mode

     Strengths Low noise and EMC disturbances

    Good line and load regulation

    Fast transient response

    Can produce very low current output

    High efficiency (75% average with some around 95%)

    More affordable for higher power

    Lighter weight

    Can't supply low voltages and

    needs to supply a minimum current





    Low efficiency (30-40% average)

    Weight (transformer)

    Larger heat sinks

    More expensive for higher power



    More noise (including impulse noise and EMC disturbances)

    Much slower transient response compared with linear

    If you have any questions about our power supply range, please feel free to call or email us.
