Exhibit 31.1


      CERTIFICATION OF CHIEF EXECUTIVE OFFICER AND CHIEF FINANCIAL OFFICER
            PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, Peter Wardle, Chief Executive Officer and Chief Financial Officer of
ProtoSource Corporation, certify that:

     1.   I have reviewed this quarterly report on Form 10-Q of ProtoSource
          Corporation;

     2.   Based on my knowledge, this quarterly report does not contain any
          untrue statement of a material fact or omit to state a material fact
          necessary to make the statements made, in light of the circumstances
          under which such statements were made, not misleading with respect to
          the period covered by this quarterly report;

     3.   Based on my knowledge, the financial statements, and other financial
          information included in this quarterly report, fairly present in all
          material respects the financial condition, results of operations and
          cash flows of the small business issuer as of, and for, periods
          presented in this quarterly report;

     4.   The small business issuer's other certifying officer(s) and I are
          responsible for establishing and maintaining disclosure controls and
          procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e))
          for the small business issuer and have:

          a)   designed such disclosure controls and procedures, or caused such
               disclosure controls and procedures to be designed under our
               supervision, to ensure that material information relating to the
               small business issuer, including its consolidated subsidiaries,
               is made known to us by others within those entities, particularly
               during the period in which this quarterly report is being
               prepared;

          b)   evaluated the effectiveness of the small business issuer's
               disclosure controls and procedures and presented in this report
               our conclusions about the effectiveness of the disclosure
               controls and procedures, as of the end of the period covered by
               this report based on such evaluation; and

          c)   disclosed in this report any change in the small business
               issuer's internal control over financial reporting that occurred
               during the small business issuer's most recent fiscal quarter
               (the small business issuer's fourth fiscal quarter in the case of
               an annual report) that has materially affected, or is likely to
               materially affect, the small business issuer's internal control
               over financial reporting; and

     5.   The small business issuer's other certifying officer(s) and I have
          disclosed, based on our most recent evaluation of internal control
          over financial reporting, to the registrant's auditors and the audit
          committee of the small business issuer's board of directors (or
          persons performing the equivalent functions):

          a.   all significant deficiencies in the design or operation of
               internal controls which could adversely affect the small business
               issuer's ability to record, process, summarize and report
               financial data and have identified for the small business
               issuer's auditors any material weaknesses in internal controls;
               and

          b.   any fraud, whether or not material, that involves management or
               other employees who have a significant role in the small business
               issuer's internal control over financial reporting.
