Wow, "History of Technology" is a very wide subject... Are you interested in early computers? The first portable watches in the 18th century? How textiles were painted in antiquity? The main international organizations on this front are ICOHTEC https://www.icohtec.org/ https://www.icohtec.org/ in Europe and SHOT https://www.historyoftechnology.org/ https://www.historyoftechnology.org/ in the US. They have regular conferences, multi-track multi-day events, which attract many presenters and participants. Papers appear in Technology and Culture (published by SHOT); ICOHTEC also publishes ICON. Besides these two large, international groups, there are national groups in many countries. And even more groups for specific areas of History of Technology, in either chronological or thematic focus.
