  • YES!!!!! I still have my 60in1 and 200in1 Radio Shack kit from the mid 80’s. Many great hours were spent on those old sprig kits developing my electronic skills as a kid! So glad to see sparkfun selling this.

  • I’m sad that you wen’t to micro USB. Every Dev board I have from sparkfun with Micro USB on it has broken off at sometime =(

  • Sharknado 5 - Sharks' learn to drive

  • Can’t wait to see the future direction of Sparkfun. I have been a long time customer and plan on being one for many years to come. Word of advise on laser cutting. Calculate how much the beam removes from the material or all your holes will be over sized =).

  • Thank you for my laughs today. I went to their website and looked up circuit repair alone and couldn’t stop laughing. My favorite is either the woman holding the soldering iron in the hot zone or the Test lead from a DMM being used to solder with.

  • This is actually how i used to make transparent circuit boards. i glue thin copper to cell cast acrylic and then etch. Then you get a transparent board. Sometimes I even over achieve and plate the copper with silver or nickel. These days I cheat though and use my LPFK protomat.

  • What ULP are you using in EAGLE CAD for the Vector graphics. I run into the same problem using the BMP importer.

  • Not all engineers are given that freedom. I work for a smaller engineering company where only a few of us are engineers and the bean counters make the decisions including the dress code!

  • OK, Flip the breaker!

  • One thing your over looking is that a 555 timer is a CMOS component and has a wide input operating range. you can get 555 times that work from 1.5VDC on up. I’ve use them all the way to 16VDC in applications. You can not do that without lots of extra circuity and a higher cost in all three of your examples above. I agree there are many niche applications for a 555 timer but that aside it is a very powerful chip to know how to use and shouldn’t be removed from your bag of tricks if you ever live outside the TTL range. The time taken to do the math calculations to use a 555 timer can be far shorter then the time to code and program an ATtiny as well.
