DS212/DSO212/DSO202 Oscilloscope Mini Stand 3D print

I needed stand for my DS212 oscilloscope. All I could find were too bulky, so I decided to design one. I posted it at https://www.thingiverse.com/thing:4347186

It is very small stand for DS212, DS02 or similar size oscilloscope or some other device. Part dimensions are 35 x 5 x 10 mm so it easy fits in any box or bag you use to carry osciloscope around.

Although You may use single stand it is more stable and practical to use two of them. Stand is tight enough to keep attached on device even if you lift it up.

Display is kept at 45 degree toward device user which is comfortable.

Fixing Baofeng UV-B5 broken battery latch using 3D printer

I’ve got UV-B5 years ago. It survived lots of use and still served fine. There was one glitch – in some moment latch that keeps battery locked was broken. Radio was still usable but it happens from time to time that battery slips out of socket and radio silently turns off. It was quite annoying but hardly fixable issue.

Until today.

As I recently got myself 3D printer (Prusa I3 MK3S) I get to an idea to model and print replacement part. As every experienced computer expert, I first looked if someone else already did that. And indeed, Thingverse member Olex had the same issue and already did modeling. […]

Užička komplet lepinja

Nekad sam subotom voleo da kad je lepo sunčano jutro, naročito u proleće, odem i kupim komplet lepinju za doručak.

Pa onda sednem u neki park na klupicu, raspakujem lepinju i stavim je pored sebe.

Uzmem poklopac, otkinem komad pa ga umočim u lepinju, onako sa tri prsta, da se dobro natopi i onda to stavim u usta i sa užitkom dugo i lagano žvaćem ne bi li osetio čulom ukusa sve do zadnjeg molekula.

I tako komad po komad prvo bi otišao poklopac.

Onda bih prešao na glavno jelo. Pošto je pretop (moča) već u dobroj meri otišao sa poklopcem, sada mogu da kidam samu lepinju bez bojazni da bi se nešto prosulo ili kapalo. […]

Mapa biciklističkih ruta u Srbiji

U vreme kada smo radili označavanje biciklističkih ruta na području Zlatiborskog okruga, napravljen je i sajt mape ovih ruta: www.mapa.iz.rs.

Ovih dana, sajt je obnovljen. Urađen je blagi redizajn i dodao je još ruta.

Podaci dostuni na sajtu pod Creative Commons licencom. Sve rute su unete i u OpenStreet mapu.

Namera je da se u narednom periodu na mapi prikažu sve obeležene biciklističke rute u Srbiji a verovatno i obeležene planinarske staze. […]

Nova era razvoja VordPres dodatka SrbTransLatin

Razvoj dodatka SrbTransLatin je prešao u nove ruke. Od sada će to umesto mene raditi Sibin Grašić. Sibin je dobro poznat kao ekspert za VordPres tako da očekujem da će on napraviti značajan doprinos u optimizaciji ovog dodatka.

Dogovor koji smo postigli je da će biti zadržana sva postojeća funkcionalnost i kompatibilnost tako da korisnici dodatka ne bi trebalo da imaju nikakve probleme sa narednim verzijama koje Sibin bude objavljivao.

Takođe je dogovor da sva postojeća funkcionalnost bude i nadalje dostupna besplatno. Sibin i inače izrazio nameru da dodatak i nadalje bude potpuno besplatan.

Verujem da je ova promena značajn korak u unapređenju dodatka SrbTransLatin i da ćemo se u to uveriti već sa prvom verzijom koju Sibin bude objavio. […]

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. […]
