A few weeks ago I was looking around for some components for my various Raspberry Pi projects and I stumbled on to ebay. I have bought and sold things on ebay several times in the past, but always mainly thought of it as a kind of giant flea market – a place to buy and sell unwanted items. I guessed I missed the news that ebay has turned into an international factory outlet. If you look for things related to Raspberry Pi, Adruino, or electronic components in general, you quickly find lots of vendors selling direct from China. The prices are incredible. Whole, fully-populated, circuit boards shipped round the world for less than what it would cost just for the postage in this country.
I was so intrigued that I thought I’d give it a try, so I ordered a selection of interesting and/or useful items.
A packet of stuff arrived today and I eagerly opened it. Mostly it was just as I expected (although there is one board which I vaguely remember ordering, but can’t immediately recall what for…) The only problem was with the packing. Among other things I had ordered some relay boards – one with two relays and one with four. The four-relay board arrived largely unscathed, but the two-relay board had obviously bumped into something else in transit which had severely bent the control header pins.
I can’t be bothered to try and return this item which only cost about £1.50, so this means if I want to use it I will need to repair it. My first attempt will be to try and straighten the pins by gently adjusting them with a pair of piers. It seems quite likely that at least one of the pins will break during this process. If it does, my plan B is to de-solder the pins and replace them, either with some of my stock of generic header strip, or by simply soldering flying leads to the board. Which one I choose depends on what I decide to do with the relay board!
