New Cheaper Power supply adapters 5V and 12V in stock

Image

We offer two power supply adapters for OLinuXino: SY0612E 12V 0.5A and SY0605E 5V 1A both are produced in Romania by Sunny Computer Technology Europe SRO, which is factory established by Sunny Computer Technology China.

These adapter are with good quality, come with all certificates and meet all safety standards, but they are bit expensive.

We found cheaper adapters manufactured in China which are at half price than these manufactured in EU.

Here we disassembly both to see the difference:

1. PCBs on both adapters are made by cheap FR2 material;

Image

2. Electronic components, capacitors, transformers, semiconductors in both adapters are with good quality; We have been diassembling ultra cheap adapters which sells for $1 with free shipping on ebay and they are really bad quality and will break after few plugs on the mains, there are no distance inside between high/low voltage parts and it’s quite dangerous to use such adapters at all, but this one is not such case. The Chinese adapter have even bigger air distance between the high and low voltage part than the EU made, but I think this comes from the fact that EU adapter have protective coating and is allowed to have narrow distance.

3. EU adapter uses wires with bigger diameter, Chinese is made with thinner cables which for sure will withstand the small currents which are used, but will fail sooner if somebody pull or twist the cable.

Image

4. EU adapter PCB is with protective coating on the solder side (which make surface glossy) and which will protect the PCB when working in humidy enviroment, the Chinese adapter have no protective coating.

Image

5. EU adapter the power connector is with springs inside which always guarantee good contact with the power jack on the board, Chinese connector is simple with no springs inside.

Image

6. EU adapter have all certificates and safety standards tests, Chinese adapter may pass these, but they didn’t bother to spend money on certification and didn’t mark the adapters (actually they would mark them if we asked 🙂 but this is not the point, you can’t be sure if there is certification on goods you buy from China as they will mark it with anything you want.

Generally in our opinion both adapters will work well, the EU adapter of course is with better quality but at double price. If you want to use the adapter just in your lab or at home and you are at low budged the Chinese adapter will do the same job for you.

If you want use the adapter in project where you want more reliability or the device will be subject to high/low temperatures and humidity you should choose the EU adapter.

AVReAl – Closed Source Freeware ISP programmer for AVR supporting ARM-USB-OCD-H and ARM-USB-TINY-H

Image

AVReAl is freeware which allow you to program quite few AVRs with FT2232 based programmers like our ARM-USB-OCD-H and ARM-USB-TINY-H.

This way you can use the programmers for both porgramming and debugging ARMs and programming AVRs so no need to buy additional AVR programmer.

Shame the sources are closed so the community can’t improve it and re-use. I always do wonder if you make one software freeware why you would keep the sources closed (ahamed by the maccoronee style programming mayby? or putting malware inside 😀 ).

Souliss – Home Automation with AVR-T32U4 + WIFI + MODIO2

Souliss is Smart Home Automation you can learn more for the project at http://www.souliss.net/
On this video you can see AVR-T32U4 running Arduino sketch + MOD-WIFI which adds WIFI connectivity + MOD-IO2 which adds two relays and GPIOs and aplication running on Android phone which controls them.
Great work Dario!

Bulgarian Customs – Ignorance, Incompetence or Both?

Doing Business in Bulgaria sometimes is not fun!

I got really pissed off today like I do every time I encounter these small injustices which surround our life.
According to the Bulgarian Customs Administration this LED 8×8 Matrix is back-light for LCD Televisions!

Why? Because LED Matrix indicators as components have no import taxes, but the LCD TV back-light have 4.5% import tax.

Searching TARIC for tariff code of LED panels return this code 8531202090:

but the problem is that it have … 0% import tax which doesn’t satisfy the customs.

The local customs TARIC “specialist” decided that this is in the LAMP chapter of TARIC as there are import taxes 9405403990:


I argued for 15 minutes trying to explain that LED matrix functionality is to present INFORMATION not just to emit light, then she called her supervisors in Sofia and they confirm, the LED matrix indicators are LCD TV back-light parts and nothing else.
At this point I just gave up any arguments, as I know from past experience, the poor woman can’t put any other tariff code than what told her from Sofia, if she does they will cut her bonus, or worse decide that she took bribe to put tariff code with less import taxes.
The tariff specialists have economic education they are not technical people they make no difference between LAMP and LED indicator, but at least in Sofia central customs office I expected to have SOMEONE who at least have glue for this stuff.

To my question why special TARIC number 853120 where is expressly written LED panels exist in the tariff book, the answer was: this number is just for these large complete panels used at the railways, public places etc, the LED matrix is not there as have no controller inside! Period 🙂

So if there is LED it’s LAMP and nothing else, and not any LAMP but one of these used for TV backlight because they have highest import tax, that’s it!

I know we live in hard times of financial crisis and the government needs more money.

I understand this and I do everything I can to help Bulgarian economy. Believe me our company does export business 99% of our sales are for export, we bring money into the economy selling high tech products like Linux computers all around the world, but I can’t accept to tariff LED matrix indicator as TV backlight just to take 4.5% to the budged, this is not right!

This way producing in Bulgaria becomes inefficient immediately with 4.5% as other competitors pay nothing when import components.

Bulgarian Customs do not play fair, in fact they cheat. I still can’t figure out if this is ignorance, incompetence or just they have targets which they try to meet by any possible means, even by smashing down the Bulgarian manufacturers.

If you read the government press releases you will get impression that Bulgaria is something like heaven in Europe, we have 10% income tax, 10% corporate profit tax, everything looks so bright and cool on paper that you do not understand how come all European companies didn’t closed their factories on the spot and moved over-here.

The truth however which we all, who try to do business in Bulgaria see every day is that: Bulgaria have most ignorant and incompetent administration in Europe, sure it’s improving with the years specially since Bulgaria joined EU in 2007 and now we are lighting years ahead from the dark ages before, but this do not change the facts that every Bulgarian businessman banging his head into the administration wall several times each year in situations like this.

You probably thinking I’m affected and overreacting, this is for sure, you may bet I’m affected, but what I saw today is not isolated case.

Have look at my friend Radoslav Kolev Odyssey here original text in Bulgarian http://kolev.info/bg/evala_be_elektronna_mitnica  for those who do not read Bulgarian here is the Google’s  funny attempt for translation. I’m sure you will still get it what is all about:  http://translate.google.com/translate?sl=auto&tl=en&js=n&prev=_t&hl=bg&ie=UTF-8&layout=2&eotf=1&u=http%3A%2F%2Fkolev.info%2Fbg%2Fevala_be_elektronna_mitnica
