Surface Preparation and Finger Prints. How bad are they?

In preparing a surface for paint / glue / thermal paste / soldering / whatever, there is one thing to remember. A normal finger print is of similar thickness to cling wrap (0.01mm).

Rule of thumb. If you would you would not be happy with this kind of material on the surface of whatever you are coating, remove your finger prints.

[UPDATE] Comprehensive Arduino Flash Memory via PROGMEM

[Updated for arduino v1.6] This post is a huge set of PROGMEM examples (done as unit tests) which you can freely copy and paste into your work.

The readership level is set at those who are already familiar with the arduino PROGMEM documentation here and the use of the F() macro and __FlashStringHelper*

Its designed as a reference to save you the “lets see how to make this work” time and communicate common pitfalls. Search for the method you need to use, and see it running in working tested code

Arduino Graphing Libraries

Here is a library to write GNUPlot output from the Arduino. Now the Arduino can produce a graph output that is directly renderable across multiple platforms and cloud services. Does not rely on some gone tomorrow software + lets you edit the plot afterward.

ASCII-Art Arduino Pinouts

Managing arduino projects can be a nightmare because its hard to keep track of your hardware setup in your code comments. To enable easy documentation of pin assignments, I created a couple of ASCII art arduino pin-outs.

These come complete with ports, PWM and coms all marked. Simply paste as a comment into your code and marvel at your new found organisation.

I reckon my fan guard design is pretty damn neat. (Free Plans)

I needed some fan guards for my arcade machine and for a neat little entertainment centre hack. Playing around I made a fish-eye honey-comb screen that looked pretty good. The pattern has larger holes near the centre of the fan and smaller holes where it counts.
