Works in Progress:

[3]    Currently working on.  Researching, designing, simulating, and building novel MEMs DC-to-DC converters.  Currently experimenting with MEMs relays built at UCBerkeley.  Dr. Alon's group [link] has been very helpful thanks to Matt [link].  I'm hoping to get relays soon from XCOM [link]... fabrication delays  

  • 24th of July, 2013 Buck Converter Test with MEMs emulation relays [MEMS_Vid3]
  • 11th of July, 2013 Relaxation Oscillator Test with MEMs emulation relays [MEMS_Vid2]
  • 26th of June, 2013 Experiment 1 test setup with MEMs emulation relays [MEMS_Vid1]
  • 15th of June, 2013 testing MEMs relays from Berkeley.  1Hz gate activation, better to watch the HD version [MEMS_Vid0]

[2]    Taking a back seat. Looking at the possibility of harvesting energy from electrostatic discharge (ESD) at the printed circuit board, microelectromechanical system, and IC levels.  Designing serval different passive and active possible methods and currently in the setup phase of my test bench for future circuit testing.

  • 21st of Feb, 2013: Messing around with Turboelectric effect [Vid7]
  • 31st of Jan, 2013: Video of Terminal Test w/ and w/o grounding 1 terminal [Vid6]
  • Video of Terminal Test with new Relay 4th of Nov., 2012 [Vid5]
  • Third Terminal Test of ESD discharge device [Vid4]
  • Current setup as of the 8th of Oct., 2012 [Vid3
  • Initial ESD discharge device tests and development [Vid0][Vid1][Vid2]

[1]   Currently on the back burner.  Looking into designing (Ultra-Low Voltage) Sub-Threshold Logic family... (some simulation, learning, and literature review).

Unfinished or Retired projects:  

[2]  No longer being pursued at this time...  Scott T. Block, Yiran LiChangzhi Li, Semi-configurable temperature sensor using Shottky diode array.  The fabricated chip in IBM 90nm process should be arriving Nov-Dec 2011.  

[1]  No longer being pursued at this time...  Scott T. Block, Yiran LiChangzhi Li,Semi-configurable temperature sensor using Schottky diode array.  The fabricated chip in AMI 0.5um process has arrived August 2011 (see image below).
