I can't turn down a bargain which is why I have just bought 6 LabPro interfaces for $172.50, less than the price of one (from Ebay). So now I have 10 LabPro's, a LabQuest, 7 Pasco science workshop 500's and two 750's. I am finding that students often have difficulty running Data Studio on their laptops but LoggerPro always works fine, that's my justification for more labPro interfaces. I've tried the new Pasco software Capstone but find it a bit fussy. Will have to switch over to that soon though since Pasco are no longer supporting Data Studio. Another reason for the purchase is that I now have enough of these small interfaces to make a travelling class set that I can take to workshops. I've recently been commissioned by the IB to write a new workshop on how ICT can be used to enhance the teaching of IB physics, if I ever get to run that workshop these interfaces could come in handy. Before I put the bid in for the 6 I had already placed a bid for a single LabPro, this morning I was notified that I won that auction too. Will somebody please start outbidding me.
