Added [Desmear and Etch/pcb-design/desmear-and-etchback/nd-etchback) under Electronics->PCB Design.
A via which has been plated after etchback was done, notice the 'three-point connection'.
Update to the sed page with a new example on replacing a date format.
Added a new Coin Cell page under Electronics->Components->Batteries.
Added information about terminal block connection types to the Connectors page.
Added information about volume resitivity to the Resistors page.
New IMS (Insulated Metallic Substrate) PCBs page under Electronics->PCB Design. Includes tikz drawn diagrams.
A side on photo of a IMS PCB with an aluminium base.
New .bss Section page under Programming->Languages->C.
Added more info and photos to the Castellation page.
Added more information about current-sense resistors to the Resistors page.
Added more information about analogue and digital temperature sensors to the Temperature Sensor page.
Fixed the problem with the asterisks appearing after page headers throughout the website, for more info is the post Two Bugs Which Need Fixing Soon….
Starting using HTML5 canvas objects to draw diagrams. See the IMS PCBs page for some examples.
Fixed plugin conflict between Raw HTML Pro and Preserved HTML Editor Markup, which were both trying to do the same thing and somehow causing HTML/Javascript code in posts to get corrupted. I disabled the Preserved HTML Editor Markup plugin and now Raw HTML Pro seems to be working fine (raw HTML/Javascript is preserved when saving, and also when switching between the visual and text editor).
Updated candy-calc, fixed bug where characters where being deleted from inputs if non-numeric.
Removed non-embedded engineering related pages from website.
Made Online Calculators a main menu entry.
The “Component Packages page” is now been moved to be a sub-page of PCB Design. I have now started creating a separate page per package as the single page was getting a little too large.
New SOD-523 Component Package page.
Added Linear Regulators page under Electronics->Components->Power Regulators.
Updates to the AltiumScriptCentral repo, including a new polygon generator!
Updates to the Altium Scripting page and the VBScript page.
New RF Design section under Electronics.
New page on 2D Coordinate Rotation under Mathematics.
2D co-ordinate rotation equations.
New info about SEPICs added to the Power Converters page.
Removed the double title bug which occurred when I started using a new SEO plugin,
New tip on adding direct connect style to specific pads in Altium to the Altium Tricks And Standards page.
The Gerber file page has now been renamed to PCB Data Formats, and more information regarding other PCB file formats such as ODB++, Gerber X2 and IPC-2581B have been added.
