Be careful with ebay sellers as they sell 'FTDI based USB to TTL' I wrote to FTDI and got his answer: --------------------------------------------------------------------------------------------------------------------------------------------------------------------- However, to guarantee genuine parts, purchase via our Web Shop and Sales Network including our Global Suppliers I strongly advise not to order our products on eBay. --------------------------------------------------------------------------------------------------------------------------------------------------------------------- So I wanted to know what would be wrong with those 'chinese chips' and stumbled upon this (take the time to take a look) And there are consequences to buying fake chips The genuine ones are not that much more expensive

I observed the ISS 2 nights in a row this week. I have to say that in yesterday's observation, the ISS 'seemed' to go much slower (3x time) than the nigth before. Knowing that the speed does not change, it has to be that the relative speed is not the same depending on the trajectory. As it was flying by on thursday, from my point of view it was going very fast, and then it seemed to slow down when it's position changed. Yesterday, as it appeared and flew by on a different path, it looked as if it was going much slower. Surely more savvy people can explain this effect better than me but have you consider this in your observation ?
