We had a great turnout at Andrew’s LED workshop. It was attended by regular Hacklab members and some new faces who were visiting the lab for the first time.
Andrew discussed the basics of how semiconductors and diodes behave, and how to calculate the related currents and voltages in the circuit. He showed to drive low-power LEDs simply with a current-limiting resistor, and the limitations of that design. He went on to show a circuit for an active constant-current method of driving high power LEDs, and demonstrated various models in LTSpice.
Thanks to everyone who attended the workshop, and thanks to Andrew for presenting it! Watch this blog (and our @hacklabto Twitter) for notices of future electronics and craft workshops at the Hacklab.
