36V CNC Spindle Motor Driver
Izvor: https://pedja.supurovic.net/36v-cnc-spindle-motor-driverHobby CNC machines are usually based on Arduino/Woodpecker CNC controllers with cheap motor drivers and 775 spindle motors. Motors are specified to run on 36V but CNC machines usually run it on 24V. That means motors run on slower speed than what they can do. Some controllers are able to run 36V but 24V power supplied are delivered with them. Newer Woodpecker CNC controllers are specified...

Show Apache and PHP version in WordPress
Izvor: https://pedja.supurovic.net/show-apache-and-php-version-in-wordpressQuite frequently I need to check what is actual version of Apache and PHP on host where WordPress is running.

As I need this on several WordPress sites I decided to create plugin for that: https://wordpress.org/plugins/show-apache-and-php-version/. Plugin is...

SrbTransLatin1.66 za WordPress
Izvor: https://pedja.supurovic.net/srbtranslatin1-66-za-wordpress Objavio sam novu verziju dodatka SrbTransLatin za WordPress. Dodata je nova opcija koja je zatrebala jednom od korisnika: mogućnost da postavi specifično pravilo preslovljavanja za određeni izraz. Naime, za taj izraz mu nije odgovaralo podrazumevano preslovljavanje sa ćirilice na latinicu već je želeo specifično preslovljavanje. To je, na primer, slučaj ako u ćiličnom tekstu stoji Vindouz a želite da u latiničnoj verziji...

CNC Clamp Screw Locking Improvement
Izvor: https://pedja.supurovic.net/cnc-clamp-screw-locking-improvement With hobby mini CNC machines you get simple and very cheap clamps that are not easy to use. It is hard to fasten it because screw turns along with nut, and as screw head is in T-slot of bead it is not easy reachable to block turning. This is small rectangle peace you can attach to screw head that will block it turning within T-slot. It makes using clamps much better experience. You may make it from mdf, wood, plastic, metal,...

Dipole Antenna Center Insulator for SO239
Izvor: https://pedja.supurovic.net/dipole-antenna-center-insulator-for-so239 Building dipole antennas is always some kind of improvisation. Center insulator is quite simple and may be made in short time with jigsaw and drill. As I jumped in CNC world I need some simple tasks to learn how to use FreeCAD and other software. So, dipole center piece is ideal just for that. I’ve finished project and learned a lot in the process. Finished projects is uploaded to Thingverse: https://www.thingiverse.com/thing:4149187 You...

Rešena misterija vinčanske kulture?
Izvor: https://pedja.supurovic.net/resena-misterija-vincanske-kulture U vezi sa vinčanskom kulturom postoje dve neobične i nelogične činjenice. Vinčanska kultura je jedno 2000 godina živela bez ratovanja. To je za današnje pojmove neverovatno. Savremena situacija ne može da sastavi dan bez ratovanja. Iskopane su lule stare 7000 godina. S obzirom da je duvan u Evropu došao tek...
