Keith McClenaghan, of Moss Park, was charged at Derry Magistrates’ Court with two counts of possessing explosives with intent to endanger life and four counts of communicating false information causing a bomb hoax.
He was further charged with two counts of placing an article with the intention of causing a bomb hoax.
No application for bail was made.
The charges are in relation to two security alerts in Derry on Sunday – at Harty Court and at Iniscarn Road.
One of the devices was left outside the home of independent councillor Gary Donnelly.
Mr McClenaghan’s solicitor told the court his client had not intended to detonate the explosives and that he apologised for any disruption he had caused.
He was remanded in custody until 16 May and will appear via video link.
