| Interim Financial Statements [Abstract] | |
| Interim Financial Statements | Note 1. Interim Financial Statements The accompanying financial statements are unaudited, but in the opinion of the management of Interdyne Company (“the Company”), contain all adjustments, consisting of only normal recurring accruals, necessary to present fairly the financial position as of March 31, 2017 and the results of operations for the three and nine months ended March 31, 2017 and 2016 and changes in cash flows for the nine months ended March 31, 2017 and 2016. Certain information and footnote disclosures normally included in financial statements that have been prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission, although management of the Company believes that the disclosures contained in these financial statements are adequate to make the information presented therein not misleading. For further information, refer to the financial statements and footnotes thereto included in the Company's Annual Report in Form 10-K as of June 30, 2016, as filed with the Securities and Exchange Commission. The results of operations for the nine months ended March 31, 2017 are not necessarily indicative of the results of operations to be expected for the full fiscal year ending June 30, 2017. |

| Related Party Transactions [Abstract] | |
| Related Party Transactions | Note 3. Related Party Transactions In prior years, the Company made advances to Acculogic, Inc., an affiliated company through common ownership and management. The advances bear interest at 8.5% per annum, payable on demand. The balance including interest was guaranteed by AMT Datasouth Corp., an affiliated company controlled by the CEO of the Company. The balance due from Acculogic, Inc. as of March 31, 2017 and June 30, 2016 were $0 and $194,104, respectively. As the total amount due from Acculogic, Inc. has been repaid in full in July 2016, the abovementioned guarantee ceased to be valid. An officer of the Company charged a management fee totaling $4,500 for the nine months ended March 31, 2017 and 2016, respectively, for the use of a home office, accounting and other services. The balance due to this officer as of March 31, 2017 and June 30, 2016 were $1,500 and $21,500, respectively. |

| Commitments and Contingencies [Abstract] | |
| Commitments and Contingencies | Note 4. Commitments and Contingencies In March 2017, the Company received a letter from the County of Santa Clara, California, which claimed that the Company is delinquent on its property taxes relating to tax year 1988/1989 in the amount of $80,238.07 including penalties which should be paid immediately. The Company believes that these property taxes were related to the period prior to the filing of the reorganization of Company under Chapter 11 of the Bankruptcy Code in the United States Bankruptcy Court for the Central District of California on November 22, 1988 and the eventual confirmation of the Company’s Amended Plan of Reorganization (the “Plan”) by the Bankruptcy Court on May 17, 1990, and thus have been settled in accordance with the terms of the Plan and are therefore invalid. The Company is currently in dialogue with the County of Santa Clara to clarify the validity of the unpaid property taxes and did not record any tax liabilities related to this claim. If the County of Santa Clara does not agree with the Company’s position, the tax liabilities imposed could have a material effect on the Company’s result of operations and financial position. |
