  • We don’t know who struck first, us or them. But we do know it was us that scorched the sky.

  • I use the meanwell ones pretty frequently in devices I build, and they’ve been bulletproof. They produce pretty clean power and despite living near some pretty powerful radio and TV station towers they have done a reasonable job at noise rejection. Most of them come with a tiny plastic shield for the barrier strip to prevent you (the maker) from zapping yourself inside the case when testing or whatever (no way is it safe for “civilians” to touch but a nice added touch). They have been pretty thermally stable, and a few times I’ve tested their max current (oops) and they delivered (and I have the slagged stepper drivers to prove it)…

  • Freedom

  • Great. I don’t mean trade secrets, but working on coordinating external feeds like your big data iOT feeds, remote devices and local device software is a new challenge facing all us makers. It used to be you made a device and it had sensors and did a little data uploading or something, but now you and others are connecting field devices to big data services for us. Typically (as it sounds like with you guys) the device/local team is separate from the big-data guys, but if not coordinated well will be problematic.

  • Welcome. Can’t wait to see cool things you blog about. Particularly posts regarding integration of software dev and hardware. Many of us who are experienced developers are used to modern hardware abstraction, which is great on tablets and desktop apps, but as we do iOT and microcontroller/microcomputer type applications the whole fun is messing with hardware. Plus every time I read about how other dev organizations do things, I learn something…

  • Can you comment on the sensitivities on each of the load cells? (e.g. the 10Kg one can detect the difference of X grams, etc)?

  • We just installed a 8.5kw array via Astrum solar as part of our stats/town solar initiative (something like 200 homes in our town did it). We also faced the giant pile of money sitting on our roof via waiting for town inspection/state approval and NSTAR signoff to get the monitoring meter. Was over 2 months, which they didn’t understand why I felt my money was being lost. Now that it’s up, the only complication is it makes the roof quite slick, so large snow sheets come down when the panels warm up, we are investigating how to protect people on our front walk (20' drop)

  • Pete, are the femtos wired in parallel around the kitchen?You have many strips, so I assume each one is parallel of each other? And secondly, I assume the strip is brighter if you have fewer LEDs since 350mw/n?

  • It is also not just EM radiation, but thermal shock as well, in the sun (at least close in) it is REALLY hot and in the shade of a planet it is REALLY cold, which produces enormous thermal stresses on components. Per wikipedia the martian surface varies from a polar low temp of -153C to a daytime high of 35C (-243F - 95F). That’s at least with some atmosphere around and the thermal mass of a planet, deep space is harsher…

  • I was wondering about adding solar power to this. Is it possible to use the solar buddy and a panel to keep this charged while working. One could imagine that this would allow you to run indefinitely via solar power indoors or outdoors in the sun. Any thoughts?

No public wish lists :(
