This guide provides a detailed procedure for importing Gerber RS-274X files into AutoCAD using open-source tools. This approach offers a cost-effective alternative to proprietary software solutions. Before proceeding, ensure the following software is installed and configured: - gerbv: A tool for viewing Gerber files and exporting them to various formats (exclud... read more

My graphic LCD library (glcd on GitHub) now supports PIC24H with the ST7565R, ST7565P and PCD8544 LCD controllers. The code has been tested with the Newhaven display NHD-C12864A1Z-FSW-FBW-HTT and NHD-C12832A1Z-FSW-FBW-3V3. I... read more

After having utilized the Turnigy Accucel-6 hobby charger for a considerable period, I developed an interest in leveraging its data logging capabilities. Specifically, my objective was to plot discharge curves for certain batteries. A cursory search on Google yielded several articles, albeit with a significant amount of conflicting informati... read more

A few years ago, I purchased one of these 16×2 LCD and Keypad Arduino shields. There are quite a few of them around (including some clones?), but they are similar to this one from DF Robot: I think I bought this one from eBay a few years ago, but none... read more

In the context of a project involving the utilization of an ATmega2560 with a custom bootloader (predicated on the Arduino Mega bootloader using the stk500v2 protocol), it was found that the optimal baud rate for programming was 38400, given the use of an 8MHz crystal. The default configuration of avrdude, when employing the programmer switch, doe... read more

August 2019 update: > - All demo code is available on Github project page Version 0.4 of GLCD Graphic LCD Library has been released. It includes added support for: - ST7565R LCD controller with SPI serial interface with AVR8 implementation. This is used in Newhaven Display model [NHD-C12864WC-FSW-... read more

Update: I've been developing a handy Qt-based tool named glcd-utils. This tool simplifies the process of creating fonts and bitmaps for GLCDs. Although it's open-source, binaries and extensive documentation are currently unavailable. Feel free to check out the GitHub page. Now, let's dive into the tutorial below. Welcome to a quick guide on craft... read more

It has been some time since I last delved into a technical article, but today we're delving into the world of flash durations. Despite extensive searching, I couldn't find any comprehensive resources offering real-world measurements of flash durations for speedlights, especially t.1 measurements. Lights Tested... read more
