  • I’ve used this power supply and it has issues at low loads. It is impossible to adjust the voltage down below 5.6 volts under low loads. I’ve had better luck with the MeanWell RS-15-5, which you can adjust down below 5.2 volts under low loads, and is is a fairly constant voltage power supply all the way up to it’s rated load. It’s only a 3 amp supply though, but it was perfect for my application.

  • Yesterday, I changed my password to ‘HackItIfYouCan.’ Today, someone changed it to ‘ChallengeAccepted.’

  • This seat is taken.

  • Sparkfun, where do you get your SSD’s from?[/url]

  • Bummer to hear that it doesn’t work with a 3.3V input, I wish I had seen your post before I ordered one. I was planning on using one with and ESP8266 to PID control a crock pot (as a Sous Vide cooker) using my cellphone as the user interface. But I was thinking about controlling the input at a high frequency, say 1000 kHz, so may be that won’t be a problem? The datasheet doesn’t seem to mention the upper limit for the switching frequency, but hopefully it’s way more than 1000 kHz…

  • Uh … The letter is dated March 10, not the 7th, and it refers to 250 digital multimeters, not 2000. Perhaps the business model of buying cheap stuff from the Alibaba web site and selling it on your own site is coming to an end?

  • Tubing by it’s very definition is hollow; otherwise it’s call “rod”. It’s a bit like saying an angular annulus.

  • Damn it man! What’s the answer? He can’t keep stomping the question forever!

  • It is wonderful to have someone admit that luck, or more accurately, being in the right place at the right - opportunity - was an important element of their success. Often it is many things coming together at the right time that makes for a successful business. Without the Aduino IDE, Sparkun, Adafruit, Make, Evilmadscience, etc. would not be where they are today. Nate founded Sparkfun before Arduino, but I believe his success is deeply intertwined with the Arduino. It is great that Nate is posting this thoughts and experiences, I love reading this stuff. The Founder of Polulu has written some interesting pieces on their website; my personal favorite was his piece on open source, with his dialog with Philip from adafruit. But I digress … Good work Nate!
