DIY power hub in DIY Astronomer Posted January 21, 2017 Wow, that's mighty impressive! I'm just doing a small box at the mo just for dew heaters and charging of tablet/phone. When (if) I get a goto mount and get into AP, then I'll have to make a more substantial box that will utilise my 110A caravan battery (on a trolley) if I ever go away from home, as well as 240v for quick plug in when at home, which will be the majority. Thank you for sharing this with me. I may have to ask you some questions at a later date if possible? I'm still waiting on some parts to arrive for my box. Even if I do eventually make a more substantial box, this one won't go to waste as I'll be able to use it when fishing away for several days.
