1. I have reviewed this quarterly report on Form 10-QSB of Solitron Devices,
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

issuer as of, and for, the periods presented in this report;

4. I am 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 me 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

is reasonably likely to materially affect, the small business issuer's internal
control over financial reporting.

5. I have disclosed, based on my most recent evaluation of internal control over
financial reporting to the small business issuer'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 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.
