This came in from Steve, G1KQH, today. It is often cheaper to buy the completed, built modules from China than to buy the parts in the UK! What is the world coming to?

I bought 5 LM317s on PCB with heatsinks for a fiver:

Why bother building it any longer, that used to be half the fun! The heatsinks would of cost a Quid each over here, never mind the LM317 and the PCB with connectors..

 

Happy days
