the Lumidax website has launched!
We are excited to bring a low-cost audio range electronics development board and lab book to homeschoolers, classrooms, labs, small businesses, and techno-geeks everywhere!
New $15,000 Stretch Goal!
Firstly, I'd like to thank all of our wonderful supporters for helping us make our dream of producing educational materials a reality. In keeping with this goal, we would like to offer a deluxe and expanded version of the Bakerboard. This new version would have the following features offered to all pledge levels of $175 and above:
- A convenient binder to store the complete set.
- Components kit to complete every project in handbook.
- The power supply.
- A wire kit for your projects, also removable.
- Spiral bound lab handbook, in full color (~80 pages).
- And, of course, the Bakerboard - also removable.
With your help, we can improve the Bakerboard to this deluxe version for all who pledged at or above $175, but only if we can reach our $15,000 stretch goal! At this volume, our parts are discounted to the point where we are able to offer these extras.
The handbook will be written in an easy to understand style, ideal for homeschooling and self-teaching. Shown below is a cover shot of the handbook, which will be in full color and spiral bound (unlike the prototype shown in the video), and packed with lab activities.
The parts you will receive with the kit will correspond to the labs. You will have everything you need to complete every lab, without the requirement to buy additional parts and wire. The binder system you see in the video update is a rough prototype, and we will continue to make improvements! So tell your friends, and help us get to that $15,000 level!
This idea has been bouncing around in our family for many years and now the technology has caught up to make it a reality at a price that schools and individuals can afford. We have paired a traditional prototype board (or breadboard) with an electronics suite so that the experimenter does not have to purchase the expensive electronics test equipment needed during development. It is everything we wish we had when we were learning about circuits on a breadboard.
Our board is big on features but small enough to pack with you to school, work, or your local makerspace.
- 32 KHz Function Generator with seven waveforms
- Offset, amplitude, and frequency control.
- Audio range dual channel auto-triggered oscilloscope, 25 KHz, seven ranges.
- Spectral Display with spectrogram and waterfall mode for imaging audio signals at seven sampling rates.
- Full color backlit 320 x 240 pixel TFT display.
- Switches, potentiometers, and LEDs for projects.
- Three power supplies at -12V, +5V, +12V.
- Large surface breadboard for building complex circuits.
- Textbook/manual with solved problems and labs
There are many examples of electronics trainers on the market. All share two things in common: they are expensive, and do not offer a built-in oscilloscope and other test equipment. Oscilloscopes are invaluable tools for performing electronics work, and most are just too expensive for the hobbyist/student to purchase. The Spectral Display is a useful and unique feature as well. Our analog trainer offers all of the above features, including a function generator with a white noise source and power supply,and will retail for around $250 (less if the volumes are high enough). We are also authoring a ~50 page textbook, with solved problems and labs, in a convenient PDF format that will be freely available to all backers within a few months of the Kickstarter campaign ending. No experience is required to begin learning electronics! The manual is written in an easy-to-understand format, and is perfect for high-school and college coursework, as well as for the home hobbyist. It has never been so easy to get into electronics.
We need your help to make this work!
In order to bring parts costs down we need to order in (modest) volume, so if you like what you see and want to be a part of this we welcome you to the team. If this works out we will start work on an Arduino and Raspberry Pi compatible version, as well as a more ambitious 50MHz digital scope version. This is our first kickstarter project and we are excited to see it coming to life. Thank you for your time and interest.
Risks and challenges
Although I have been an electronics engineer for nearly 40 years, and a hobbyist before that, this will be the first time I have ramped up production of a single design beyond a dozen units. To mitigate the risks involved, I have found duplicate sources for every component and multiple quotes on board printing costs and lead times. I have also designed around commonly found components to simplify changes in my sourcing.
If this idea proves popular beyond our wildest dreams, we will face the added challenge of renting a space and hiring employees. To prepare for this eventuality we have talked with local skilled individuals and found a suitable space to work in. We have also lined up extra help for shipping and logistics. You will notice that the reward structure is tiered in a manner that allows for extra time as the number of rewards increases.Learn about accountability on Kickstarter
