"In the same conditions in which the Election Commission is holding its challenge, AAP will demonstrate its own machine, which we declare is tamperable. We are inviting political parties and all experts in the world to come," said AAP's Saurabh Bharadwaj.
Mr Bhardwaj, who had held a live demo last month in the Delhi Assembly of tampering on a prototype, said Chief Election Commissioner Nasim Zaidi is also invited.
Delhi's ruling party has been the most aggressive in alleging that EVMs were manipulated in recent state elections. But it has decided to skip the Election Commission's challenge, complaining that the rules are too restrictive and all that anyone could do was to press the buttons of any four voting machines that were used in recent state elections.
AAP says its hackathon will prove that "no machine can be tampered with by only touching buttons".
The Left party CPI-M and the Nationalist Congress Party were the only ones to apply for participation in the Election Commission's challenge.
The Commission had invited seven national parties and 49 state parties to apply for the challenge, which will be webcast live.
