Re: How do I write a review for product

What people above have said makes sense... trouble is, I HAVE bought the product, well before trying to review it, AND was logged in on the account used to buy it. And I have written many complimentary things about their products over the years.... http://sheepdogguides.com/ec/SF09351-LCD.htm ... fo...

How do I write a review for product

When we browse the Sparkfun products, at the bottom of each's page, there are comments and reviews.

I have no problem leaving a comment, but I haven't figured out how to leave a review. Hints, please?

Particle Photon w/ Android or XP

Four hours to "get in" to a new Photon. Some of the gory details below. Finally in, not entirely sure how or why at this stage... but a few pointers to things that were problems for me... If after a failed setup, and a power cycle for your Photon, it is winking green, that's it trying... and failing...

Particle Photon Secret

Very frustrated with the promotional material regarding Spark/Particle Photon. Finally managed to understand that "Spark" was the old name for the people behind Photon, and that it isn't out of Sparkfun. Although Sparkfun seem very excited... or want to be seen as excited?... about the Photon. But t...

.lib and .mod files for KiCad... ProMini so far

I offer free a .lib and a .mod file for KiCad so that you can put an Arduino Pro Mini as a module (in the broad, not the narrow KiCad, sense) on a PCB you are designing.

HowTo: Input/output across web. Teensy, Wiz820io

I recently started with the Teensy 3.1, plus a Wiz820io Ethernet module. Full sourcecode available for download. My ArduServer software ported across without great drama. Once it was in the Teensy, I able to do much more than I achieved a while back, with a small Arduino and W5100. From anywhere on ...

Re: Need some ideas for detecting phone vibrations

Three things... Two on avoiding false positives: Have a switch... it could be "automatic" by some mechanical means... that enables the "ring alarm when you see vibration" only when the phone is on the stand. I wonder if the module that causes the phone to vibrate throws out some electro-magnetic wav...

I also recommend creating your own custom library to store parts in.... In another thread someone pointed out that besides the other good reasons for adopting this working practice there is the fact that from time to time, you will probably want to download the latest revisions to KiCad... and when...

Anyone used KiCad?

Anyone used KiCad? (PCB design software) I've been "playing" with it... very impressed... but don't want to spend (more) hours and discover down the road that it has some major deal breaker. Free. Open Source. Versions for Windows (I use it with XP), Linux, Mac. (A while ago, someone didn't like the...

Re: Manufacturing your own PCB

For description of a hobbyist way to make PCBs (which will clarify the above for you), see... http://www.arunet.co.uk/tkboyd/ele1b...

ANN: An interactive webserver in an Arduino, with code

I've used one of the "new" Arduino Ethernet Shields (W5100 based, Sparkfun product DEV-09026) plus an Arduino Uno to put a server online. It has buttons to turn an LED on my Arduino on and off across the 'net, and a light sensor "watching" the LED, so you can see whether it reacts. (The light sensor...
