Useful baby stuff

I've been asked a lot recently by friends for product recommendations for useful baby things (our son is now 18 months old). I remember how daunting it was to have a new baby on the way. A few friends dropped off literally truckloads of hand-me-down baby stuff, much of which were confounding collections of plastic tubes, cylinders, and funnels that were apparently supposed to connect in ways that might be useful. Every kid is going to be very different, but here's what Mako ended up using...

How to stop spam emails from Amazon third-party sellers

Our family orders something from Amazon at least once a week.

We have very few problems with third-party sellers, but there is one major difference between buying something Amazon-stocked and from a third-party supplier: the inevitable follow-up email that essentially puts the buyer on a mailing list they never opted into.

Synchronized Sony a7r / a7s cameras

I'm cobbling together a synchronized shutter-release / timelapse controller for triggering Sony a7 series cameras, and it seems to work! Although, as is usual when chaining remote cables together, I'm observing some strange behavior. For example, when I connected only a 2.5" to Sony Multi-Terminal cable plus a 2.5" to 3.5" cable adapter, all physical controls on the Sony camera disabled themselves (but I was able to trigger the camera via remote). Moving to a wired Satechi remote from a wireless Neewer remote seemed to free up physical controls, although I haven't done exhaustive testing. Still, the proof of concept is sound, and I'm going to order the remaining cables to get 4 cameras synchronized. I haven't tested how accurate the sync is (yet), but I'm targeting long-exposure timelapse, so having extremely accurate sync isn't required.
