There are seemingly endless examples of these machines on the internet, some with quite detailed construction instructions (for a few examples see cdrom recycling). We might also call this style of device a “2D printer”, or “CNC plotter”, but I'll stick to… text/html 2021-07-30T15:55:31+12:00 http://projects.scorchingbay.nz/dokuwiki/arduino/Controller_for_Cybot?rev=1627617331&do=diff [Cone icon by Fornax, CC-BY-SA 3.0, wikimedia commons] I have received a discarded Cybot robot which is mostly complete and decided to replace its control chips with an Arduino, which will require writing software to control the motors and receive inputs from the ultrasonic and LDR sensors. There are quite a few projects on the internet that reuse the Cybot hardware but replace or modify the sensors and interface boards - the objective with this project is to make a substitute for the pr… text/html 2023-03-12T22:17:32+12:00 http://projects.scorchingbay.nz/dokuwiki/arduino/Spin-Scan?rev=1678612652&do=diff [Original camera setup to manually produce 360° animation.]I wanted to automate the creation of 360° animated GIF photos. This sort of thing has been done many times in various ways by many people, so I am re-inventing the wheel here, but I don't have their solution to hand. The obvious way to do it appeared to be to use an Arduino board to control a stepper motor and synchronize the camera. I had previously created such animations by manually moving the camera and taking many photos, then ma… text/html 2023-03-12T22:09:51+12:00 http://projects.scorchingbay.nz/dokuwiki/arduino/capmeter?rev=1678612191&do=diff [Cone icon by Fornax, CC-BY-SA 3.0, wikimedia commons] Overview There are many articles about measuring capacitance using an Arduino. In the simplest form they just measure the time to charge or discharge the capacitor with known voltage through a resistor. But some are elegant, requiring no additional components at all!. This concept seems a little ridiculous, but see the articles on Codewrite.co.uk by Jonathan Nethercott, linked to in the references section below. With a bit of insp… text/html 2023-03-12T21:59:48+12:00 http://projects.scorchingbay.nz/dokuwiki/arduino/fdd?rev=1678611588&do=diff [Cone icon by Fornax, CC-BY-SA 3.0, wikimedia commons] Overview There are lots of floppy disk formats that it would be nice to be able to read without actually having to have the original computer to read them. Eg Amiga format disks, variable speed Apple drives etc. There appear to be quite a few projects out there with various implementations. Initially this project will just be a place to collect and document ideas. text/html 2022-08-23T11:31:12+12:00 http://projects.scorchingbay.nz/dokuwiki/arduino/ks0073_driver_library?rev=1661211072&do=diff I have a pile of display panels from Siemens optiPoint 500 series phones, that I wish to use in Arduino projects.

These are 2 line by 20 character LCD status displays that have no horizontal gap between the two rows of characters. This suggests possibilities of creating double height characters that look natural. Some of the character sets/fonts implemented here could be used on other 2 line LCD displays, and some rely on the existing inbuilt character set.
