From a design perspective, as per the manu's recommendations, R1 should really be 240, make R2 a 1K preset to trim the volts.... |

thank you all I have a successful circuit, at least on the breadboard lets hope I can transfer it to the verostrip with the same results |

just found the 317 on the board is knackered probably my fault but good to know reason. Andreas that pdf is teaching me many things, as i stated above my experience is very limited and I have never fully understood a lot of what i do for example I didnt put protection diodes on the lm317 because the schematic didnt show them. I now know they are there to protect from discharge from the capacitors and their inclusion would have stopped me blowing 317's |

Oh dear :zap: Fortunately they don't cost a lot.... :lol: :lol: |
