36V CNC Spindle Motor Driver

Hobby 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 to run on 24V only.

Some specifications claim that 775 motor used for spindle runs at 3000-6000 rpm when powered at 24V and gets up to 9000 when powered at 36V. I wanted to run spindle at maximum possible speed for better milling results. […]

Show Apache and PHP version in WordPress

Display Apache and PHP versionQuite frequently I need to check what is actual version of Apache and PHP on host where WordPress is running. For some reason, WordPress displays just it’s own version and you have to use other means like logging to hosting control panel, or uploading some independent script.

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 very simple, it just hooks up to version displaying for WordPress and adds additional version information. It is displayed in Dashboard at lower right corner of each page. That is all. […]

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 ne bude Vindouz nego Windows.

SrbTranslatin od nastanka ima mogućnost da u rečniku sadrži takva, specifična pravila preslovljavanja ali bi ona morala da se unose u tabelu preslovljavanja koja je deo koda, što je nepraktično.

Imam u planu da omogućim da korisnici mogu kroz administraciju dodataka da dopunjuju rečnik sostvenim pravilima za preslovljavanje ali kako to do sada nikome nije tebalo a iziskuje značajn posao, nisam na tome radio. […]

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, whatever you like.

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 may use CNC mill or 3D printer to make this part. Pay attention to use material strong enough to survive possible strong forces. […]

How to setup multiple domains for projects on local Uniform Server (WAMP platform)

I just installed Uniform Server and I am delighted. First impression is that it is easy to set, efficient and clean. Great Work and completely Open Source and free!

I am in web stuff for decades and none of the tools I used for local development environment seems so nice. Kudos to developers.

In my workflow I use separate local domains for each project. There is number of reasons I never embraced default local www site with each project in subdirectory as it is widely proposed by all WAMP platforms. I usually just use public domain for the project and add .loc […]
