Ćao Zdravo ERSA, Nova lemilica je NEO

Evo dugo nisam pisao blogove na temu elektronike i opreme za elektroniku. Takvo vreme neko došlo da se čovek bavi svim i svačim a zapravo nisačim, te na kraju shvatiš da jedeš samom sebi energiju. Sasvim dovoljno malo da se okreneš nekim svojim stvarima i staviš veštačku inteligenciju sa strane. Zapravo jasno jeste a nije, ali nisam od onih koji je na svoj website postavio AI kompatibilno ili Spreman Sam za AI. Prosto nisam hteo ništa da menjam vezano za AI jer ne znam šta da stavim. No, nije mi poenta da kritikujem druge već sebe. Evo i zašto.

Prošle nedelje odem do radnje za elektroniku da kupim LED diode kako bih napravio svetlo koje se uključuje kada počinje da pada noć, i gasi kada se zora budi tj. sviće novi dan. Naravno, znam da nemam lemilicu tj. da je imam, Ersin Štap i da je vrh otišao, te da moram uzeti novi. Novi vrh je koštao 1400 dinara, sve zajedno sa dvadesed LED belih dioda 2200 dinara. Nije malo. Da uzeo sam i fotoćelije tj. foto-otpornike. Super! Sve je spremno. Stavim šemu na protoploču i krenem polako da ređam komponente. Sve radi super sa četiri LED diode. Odabrao sam ULN2803 drajver za LED i komparator da trigerujem razliku između noći i dana u kombinaciji sa fotoćelijom. Super!

Pored svega toga uzmem i napravim video klipove gde sam nahvalio Ersu kao da mi za to daju 1500 EURa mesečno. Stvarno sam bio zadovoljan sa lemilicom, neverovatno. Možeš da je držiš satima, da lemiš, uvek ista temperatura, super je. Al eto na današnji dan posle nekoliko godina, nekih 7 do 8, CRKO GREJAČ, PROSTO REČENO. Nisam mogao da verujem. A taman sam je pohvalio. Kao da te neki Nevidljivi Vanzemaljci gledaju i namerno čačkaju da se nerviraš i da budeš pokunjen, da odustaneš.

Vrh lemilice Ersa 

Međutim. Odem ti ja do kineza da kupim novu. Odem tamo njega nema. Pitam prvog slučajnog prolaznika. Dobar dan! Dobar dan! Jel znate gde je ovaj Kinez? Kažu oni meni nema njega već jedno nedelju dana. Reko. E tačno, tačno. Važi hvala. Pređem semafor. I skontam, pa da imam tu i farbaru. Dobar dan! Dobar dan! Jel imate lemilice? Imamo! Imamo lemilicu BAŠ ZA VAS! BAŠ ZA MENE? Reko, super. Doša sam kući. Osim što je cena 1800 dinara, izgleda da nije loša, mada sam mogao da kupim i lemilicu na Temu za 400 dinara, istu, koliko košta i kod Kineza. Ali meni je danas trebala lemilica! I dobro, ajde 2000 din lemilica nije problem, malo je skuplja za kvalitet. Otvorio sam je i bio sam zadovoljan. Ali posle jedno 3 sata lemljenja skontao sam da je vrh već načet! Pa čoveče lemim tek 3 sata! I to je to. Ersa košta, traje godinama, crkne i ona. Ali Neo, ta lemilica iz Matrixa, BAŠ ZA MENE, ona je svega 3 sata lemila i već je vrh načet. No dobro. To nije jedino. Danas je dan baksuza :-) Nije da nisam zadovoljan u neku ruku i jesam. Nego, nije mi jasno kako to da je na protoploči šema bila dobra i radila a kada sam komponente montirao na pločicu, radila jeste ali sam imao pad snage. I sad ne znam o čemu se radi? Ništa, ostavio sam sa strane. Verovatno ću raditi neko drugo rešenje.

 

Neo, Matrix lemilica :-) 

 

 Nisam zadovoljan te ćemo raditi dalje...

U suštini kriv sam samom sebi jer nisam toliko trebao da hvalim Ersinu lemilicu, ali se nisam toliko ni iznervirao. Neo nije loš, ali iz aviona se vidi da je Ersa, Ersa, bez obzira što je ova moja crkla. Da imam novac ponovo bih uzeo Ersu!

Fake VC830L digital multimeter

Image
This article is intended to explain some bad things about cheap digital multimeters since these devices are available in large quantities in Serbia. The key point of this article is security since cheap digital multimeters are not tested/produced according to standards. VC830L is one digital multimeter available in electronics distribution stores in Serbia, but we will avoid company names, since this article is more about “ pay attention before you buy ” cheap digital multimeter. The VC830L is about 10 euros, you cannot expect too much, but if you are not able to buy professional digital multimeter which costs over 100 euros, you will certainly buy the cheap one. Front mask: VC830L digital multimeter. The part interested for us is security so let see what we actually have regarding VC830L digital multimeter. It has three input connectors, starting from the left side: we have connector for 10 amps, common connector (COM) and the right one intended for voltage, r...

Electrolytic capacitors and design rules

Image
This article is in tended t o ex plain the bases about electrolytic capacitor , where t he y are used, basic construction, RLC circuit and much more. This is a fir st article about capacit ors and this article is based on zilsel-invent previous article about low pass filters at the following link : Low pass filter and voltage stabilization Electrolytic capacitors and design rules T he f igure #2 presents already used electrolytic capacitors. As we can see electrolytic capacitor is polarized device which means that it is important to pay attention during capacitor assembling to the PCB (printed circuit board). Depending on the capacitor manufactures, in some cases negative lead is marked with a negative sign , and in some cases positive lead (capacitor pin) is marked with a plus sign . Beside polarization mark, there are also labels about capacitance (for example 470 microfarads ) and maximum allowed voltage (for example 10V). The maximum allowed voltage is important parameter r...

How to design LM324 Astable Multivibrator

Image
This blog post is intended to describe how astable multivibrator works based on LM324 operational amplifier, RC timer and positive voltage divider circuits. This is one way to implement astable multivibrator since additional options are available like: specialized signal generators or 555 timer integrated circuit configured to work as an astable multivibrator . There are two states related to astable multivibrator based on RC timer or an analog timer (there is also a digital timer integrated into the microcontroller for example, but in general, digital timers are based on astable multivibrators implemented with quartz or resonator external oscillators, since digital timers count PWM /clock oscilations . Anyway, there are different types of astable multivibrators in order to provide clock cycles): charging and discharging. Charging   To describe charging state we will start from beginning with the completely discharged capacitor C (it has zero volts betwe...
