302 CERTIFICATION

I, Craig S. Laughlin, President and
Chief Executive Officer of Dotronix, Inc., certify that:

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 information
          included in this 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, the periods presented in this report;

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 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 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.
