Ray

Have you been interested in working with Arduino but don’t know where to start? We have got you covered! Ray will lead attendees of this class in building a digital music box to take home and show off with pride. In the process, students will assemble a battery-powered Arduino with an input switch and a speaker. Then, students will upload sketches to play a melody.

No analog in your toolbox? Do your circuits see nothing, hear nothing and say nothing? Let's change that pronto! In this class Ray will introduce some of the basics of analog signals, op-amps and sensing temperature to design a mixed-signal (analog and digital) circuit.

Have you been interested in electronics but don't know where to start? This class does not assume any prior experience or knowledge whatsoever so here's your chance!

Attendees will learn about basic concepts such as voltage, current, resistors and capacitors. Intuitive analogies and diagrams will be used, minimal math beyond a few bits of basic algebra will be presented.

Electronics enthusiasts use transistors as switches and amplifiers in a wide range of applications. While they are relatively simple devices they are often a source of confusion and frustration when we are called upon to use them. NPN? PNP? MOSFET? JFET? Which of the 10,000 in the catalog is the right choice? In this class…

If you haven't learned to solder yet or if it has been so long that you'd like to learn again we've got you covered! Ray and Issac will teach attendees how to solder thru-hole components while assembling their own Knox Makers badge (pictured above). The circuit includes 6 LEDs, 6 resistors, and a coin cell…

We were looking to level-up our badge kits in the electronics store and think the result is awesome! Join us for a guided build of the badge pictured above and then take it home to earn geek street cred among your soon-to-be-jealous friends. Attendees should be able to solder thru-hole components but don't need to…

In this class Ray will lead you step by step through reading a schematic and translating it into a prototype on a solderless breadboard. Each attendee will build a circuit using an integrated circuit, resistors, capacitors and diodes to take home and show off to friends!

If you've been building circuits for some time and want to improve your understanding of just what's going on then this is a great class series for you!

If you've been building circuits for some time and want to improve your understanding of just what's going on then this is a great class series for you!

NOTE: This is a two session class; January 12 and 19, 6:30-8:00pm each day.

If you’ve been building circuits for some time and want to improve your understanding of just what’s going on then this is a great class series for you!

Many common circuits you’ve used are really filters at heart:
– Bypass capacitors
– Switch de-bouncing
– Arduino PWM audio output filter
– Stereo speaker crossovers
– RF communications filters

Ray will teach attendees about several interesting concepts:
– How to think about signals in the frequency domain
– Types of filters
– How filters are used
– What’s an FFT and is it useful to me?
