09:44 – While Barbara cleans house this morning, I’m making up international chemicals bags for both the biology and chemistry kits. I need both because I have outstanding orders for both that are to ship tomorrow. Fortunately, it’s pretty easy to build an international kit of either type. I just open a US-only biology kit or chemistry kit, remove the “problem” (restricted) chemicals, drop in the appropriate bag of international substitute chemicals, and transfer the contents of the box to one of the boxes we use for international shipping. Those are larger than the USPS-provided boxes we use for US and APO/FPO shipments, which leaves room for more padding. I’ve never had a kit damaged when I used the USPS boxes for shipments to Canada and APO/FPO addresses, but these internationalized kits will be going to Great Britain, Australia, Hong Kong, and so on, so a bit of extra padding might be a good idea.

    Nah, don’t bother for Australia. We no longer use kangaroos to deliver the mail and parcels… 🙂

    Anyone have recommendations for reliable powerline ethernet adapters? Thanks.

    I use the Netgear powerline 85 in my house. I have three of them installed and they work like a champ. Except when the house power is down since they are not UPS-able:

    Any particular reason for not just using wireless?

    I work from home, and was using wireless, and it worked 98% of the time. Since I switched to the same power networking system that Lynn uses I have had none of the issues I had with wireless. I still use wireless for mobile devices, but I wouldn’t dream of using wireless for a PC at a fixed point in the house.

    My TV DVR did not have a wireless option for downloading shows from the tubes. And it works like a champ with zero reboots. The power adapter is just an ethernet repeater with zero settings to muck with. Just plug in two of them and voila, you are up and running.

    I have three devices where my TV is located that can use a network connection. I have not hooked them up because the benefit was not worth the hassle to run wires. The Apple TV uses wireless so that is not an issue.

    So I have a question. If I was to install some power line adapters, is it possible to connect a small switch to the output of one of the adapters and hook up multiple devices? If that is the case I may just get a pair and connect those three devices.

    Yes, you could hook up a small switch to the Ethernet port of one of those adapters. You can even get a four port switch built in to the adapter.

    Cowboy Slim used to use powerline adapters. Then one day he did some throughput tests, after which he found an alternative. I’m not sure if he ran wires or went wireless.

    YMMV.

    A while back I picked up 2 8 Port 10/100 Mbps Fast Ethernet Switches from Monoprice. Really handy to have around, and the price was right.

    The number one complaint I have read is that the adapters have to be on the same circuit. I don’ use power line adapters so I have no FHX.

  13. dkreck says:

    Not the same circuit but the same leg. North American Power is generally 240V composed of two legs of 120V running in opposite sync. You can get bridges to place on a 240V outlet to carry rf signals from one leg to the other. (or you can just leave a 240V appliance like the AC running all the time)

    The Wirecutter (great review aggregate site when everything is tl;dr these days) likes the TrendNet TPL-401E2K powerline networking adapter,

    The Best Powerline Networking Adapter is the TrendNet TPL-401E2K
