Building Electronics Kits at JOTA

Over the years a wide variety of electronic kits have been constructed. Noisy ones like sirens, hee-haw sounds, monophonic organ, and so on. Others have lights that flash in various combinations, such as the image on the left.

Programmable Monophonic Organ (2017)

Another old favourite returns this year, the monophonic organ. Pressing the piano-shaped keyboard plays the corresponding note. Of course, this version is programmable, much like the Moog Synthesiser from the 1970s. With a bit of practise the audio possibilities are amazing.

The kit is still under development, details will be added as the design firms up.

Programmable Bike Tail Lamp (2016)

For 2016 the bike tail lamp makes a return this year - with a twist. It's now programmable using a DigiSpark Micro-controller, This is a very small computer, the computer board measures just 23mm by 23mm! It uses the same Arduino programming language and environment that we used last year. It has four super-bright LEDs that can be flashed in any combination you can think of.

For mode details have a look at the Arduino Bike Lamp pages.

Arduino (2015)

In 2015 the level stepped up a few notches, with the construction of a tiny Arduino computer. The Arduino Nano comes pre-assembled on a small circuit board wich plugs into a larger sized board with light emitting diodes, switches, potentiometer and other input and output devices.

Tis kit matches the Power House Museum's Thinker project, so all the programming examples developed for that work on this one. For mode details have a look at the Arduino pages.

Windmill (2014)

The return of a simple but effective circuit, the windmill, with light emitting diodes that flash in a rotating pattern.

Cyclic Sounder (2013)

An audio tone that changes frequency with the flashing lights. Sure to be loved by Scouts and hated by everyone else :)

Bike Tail Light (2012)

Uses three very bright light emitting diodes to create a flashing red tail light for your bike.

Red and Green Flasher (2011)

Using two light emitting diodes and a 555 integrated circuit this is the classic flashing light kit. Use a multimeter to measure the components.

Electronic Dice Kit (2010)

At the press of a button seven light emitting diodes flash briefly and one pattern stays lit, representing a number between 1 and 6. Truly random and never rolls off the table!

Siren and Windmill Kits

The picture below shows the windmill, with light emitting diodes that flash in a rotating pattern, and a ding-dong doorbell. Guaranteed to annoy you when visitors arrive.
