1. I have reviewed this report on Form 10-QSB of Dotronix, Inc.;

2. Based on my knowledge, this 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 report;

3. Based on my knowledge, the financial statements, and other financial

4. The small business issuer's other certifying officer 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 report is being prepared;

         b) Evaluated the effectiveness of 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 reasonably likely to materially affect,
         the small business issuer's internal control over financial reporting;
         and

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

         a) All significant deficiencies and material weaknesses in the design
         or operation of internal control over financial reporting which are
         reasonably likely to adversely affect the small business issuer's
         ability to record, process, summarize and report financial information;
         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.
