Jamie Hutchinson threw the plastic bottle, filled with petrol and fitted with a fuse, onto artificial grass behind his neighbor’s Beckingham Court bungalow on March 2 last year.
A similar glass device was discovered after his “terrified” victim told police, prosecutor Abigail Joyce said.
He believed the arson attempt was revenge for reporting Hutchinson, 38, after threatening the man, described as vulnerable, with a bow.
The next day, Hutchinson accused a man who lived across the street from him of spitting on his car before calling at his front door and rushing at him with the Taser.
“He managed to force the door open,” Ms Joyce said. “He heard the Taser crackle as it was discharged but he was not hit.”
This victim decided to “shut up in the hope that this would be the end”, but ten days later Hutchinson spat on him in the street and told him he had Covid.
“Worried about what the defendant would do next,” he called police after seeing Hutchinson hack into a sofa and a fence with a machete.
Police discovered an arsenal in Hutchinson’s home, including throwing knives, a sword, a fuse cord that matched the bombs, a dart shooter, a crossbow, a miniature cannon with gunpowder, bows, arrows and a can of gasoline. The Taser was charging next to his bed.
He denied everything during his interview, but later admitted that he had been under the influence of the mamba at the time.
Benn Robinson, mitigating, said the defendant had already served the equivalent of two years on remand and the board was in the process of finding him another home.
Nottingham Crown Court heard he hoarded the weapons while mentally ill and ‘clearly had a persecution complex’.
On Friday, Judge Stuart Rafferty QC adjourned the sentence for three weeks so that new accommodation, “somewhere where he does not bear the stigma of what he has done”, could be found.
He said: “If he came back, they would probably temporarily lift the bunting and set it on fire.”
Hutchinson pleaded guilty to attempted arson, assault and possession of an offensive weapon.
