2011 WyoLum Innovation Grant

WyoLum’s [http://www.wyolum.com] mission is to “Promote Open Source Hardware”.  To that end, we are pleased to announce two $1000 (USD) grants to be awarded to the most qualified applicants.

Qualifying projects will be 100% open source (hardware and software) from development through to production.  WyoLum team members will be available for advice and assistance throughout your project.  If you have a killer idea, but have never fabricated a PCB, programmed a micro-controller or designed an enclosure, don’t let that stop you from submitting your idea. If we can’t immediately assist you, we will learn it together.

Submit completed applications to grants@wyolum.com by December 3, 2011.  Applications will be excepted in a combination of video (encouraged), html, .odt, .doc, .docx, blogpost.  We will make all reasonable efforts to receive and evaluate your application.

Download the Application as a Google Doc or PDF!  Share the Poster!  We are excited to hear from you!

Each ClockTHREE is Unique

Adam and Julie

I am coming to appreciate a cool fact about ClockTHREE and ClockTHREEjr: Each clock is unique. With the custom faceplate and imminently custimizable firmware, no two clocks are alike. This is possible because, even though the entire design is digital, the format allows easy modification.  We have helped several customers  to design thier perfect clock.

Pictured above is a clock to commemorate Adam and Julies recent nuptial ceremony.  This two-tone clock will celebrate their anniversary each year by scrolling an anniversarial message throughout the happy day.

 

I2SD library

This library has a single class call I2SD with simple interface (see below).  A call to Wire.begin() must be made before any of these calls.  See Hello World to see a simple example of the library in use.

  /* Transmit n_byte bytes of data to I2SD card.
   * return true if identical bytes are returned from I2SD card
   */
  boolean ping(uint8_t* ping_data, uint8_t n_byte);

  /* Move file cursor to addr bytes from the beginning of the file
   */
  void seek(unsigned long addr);

  /* Open a file with the specified name and mode
   * May induce I2SD_OPEN_ERROR on I2SD card
   */
  void open(char* filename, uint8_t mode);

  /* Read n_byte bytes of the current file.
   * File must be open for reading
   */
  uint8_t read(uint8_t *data, uint8_t n_byte);

  /* Write n_byte bytes of data to current file
   * File must be open for writing
   * May induce I2SD_MODE_ERROR on I2SD card
   */
  void write(uint8_t *data, uint8_t n_byte);

  /* Clear any error on I2SD card.
   * May induce I2SD_MODE_ERROR on I2SD card
   */
  void clear_error();

Oops: ATTN Vic and Florin!

While writing this I realized I left a bug in the inital version of the code.  The I2SD will show an error if the file “DEFAULT.TXT” is not present on the SD card.   So add that file to the root.  It does not have to have any bytes.  It just provides a default file pointer.  This will be taken care of in the next version, or you can delete the offending lines and re-load the script.
