  1. After I did not see the board name (usually write the PCB model), I removed the front panel. But obviously this is a super new version of a PCB and there is no information. If the connector ( sck sda rst vcc gnd ) ... I now see that some of the captions are used in the oled displays. And it's actually programmed or connected to a display instead of a 7-segment indicator ?
  2. Hello guys I have one request. I bought a hot air station .This device - at a low price - where the main role for the job is using a microcontroller HR7P169 There is a connector option on the PCB and I suppose it is for reading and overwriting. After the station for me was 30 euros and the microcontroller for almost 2 euros. What will be needed to try reading the code and having it as a file this device is powered directly to the electrical outlet to the white connector, and when I set the temperature, I see the heater flashing differently according to the temperature and the power of the air jet. When placed, the stand stops heating and only blows while it is needed or if it reaches 100 degrees and shuts down Chips using in this device : Upper left -> Eastsoft HR7P169BFGTF Upper right -> F7103 in the middle on pcb -> LM358 in the below the transformer -> PN8370 Using moc3023 who the control bta12/800A
  3. Ls mecapion apm-sc06ddn-kx Used in cnc machines - I think so
  4. Hello I am thinking of using an IR2130 chip to drive powerful transistors. The control will be with pulse generator and 74HC175
  5. Ls mecapion apm-sc06ddn-kx 3 phase , 200 V , 3.82 A , 550 W , 200 Hz max , 2000 rpm Hello . I have this electric motor, but I have no control. Can you help me with a scheme to manage it
  6. Hello I have an idea, but I do not know how. I noticed that the charger for my phone if the phone is not turned on to charge - it does not consume anything. But when I turn on the micro usb connector - then begins to consume. Now fit a box that will convert unbalanced audio signal into balanced. But the transformer can not fit in the box of the device and the target mount it in an external box. I do not want a permanent transformer is plugged in.
  7. Hello, everyone I need your help to assemble charger for lead-acid battery charger . I have a ( 6 volt 12ah )battery which was forgotten and for many months and he had died . Added distilled water and got her back to life with the ordinary charger. But inside I see white crystals and need scheme for desulfator charger .. On the Internet there are many schemes but do not know which of all What I would like to have the scheme is to control the charging current and switch 6 or 12 volts. For now that I have is 6volta 12 AH , but may in the future I need for larger or smaller as capacity.
  8. In test this transformer give : Without load - 24 volts. 50 watts under load - voltage drop of 23 volts 85 watts under load - voltage drop of 22 volts The stand of the soldering iron was not very stable - - one time is fixed and sometimes not :) after few hour the end result satisfies me 100%. And later i will add digital thermometer and will fit bottom the key -> information about the current temperature - information coming from the sensor heater I apologize for the quality of the photos - and if someone does not like manufacturing. But I'm satisfied.
  9. hello I found a circuit filled with ICL7107 and 3 1/2 7seg led display After simulation in the program " Proteus 8 professional " - i see the circuit work well . After simulation in Multisim scheme soldering station controller -> It see - out from IC2C - Vref that about 500mV and the output from IC2B - voltage varies - from 213mv to 500 mv . when i build in box - i upload pics . :)
  10. hello First, I apologize that my English is not very good and at times I use google translator :) But most of them understand words I decided to buy a soldering station, but those who themselves control the temperature sensor and heater use - were quite expensive in my city. After reading information on the internet - I saw that they are working on 24 volts. I had an old transformer - which I rewound the throttle from a street lamp - and has output parameters: no load at the output 25.4V After turning on the car lamp series connect 40 watts + 45 watts = voltage is 23.4 volts - the current in the lamp is 3.8A. Once convinced that the transformer does not hum and gives a current that I need - I decided to use it. Maybe the voltage is slightly below the required 24 volts, but it will do the job I liked the controller Hakko 936 - that no digital thermometer for temperature visualization. After I saw pdf - I thought it might add thermometer. Give advice if possible. schemes applied to the controller which costs $ 13 http://www.mmccs.com/mmarc/n0ss/hakko_936_schem-pcb_%26_mod_v1r7.pdf After the thermocouple - signal is amplified by IC2D and IC2A and feed triac driver -> IC1 turning the triac. Something like a comparator - am I right or not ? If I take the amplified signal from the thermocouple by foot "pin4 IC1" if there will be a disruption in the operation of the scheme. I found two schemes thermometer - but if you can give me a better option. 1: http://vrtp.ru/index.php?act=categories&CODE=article&article=2137 2: http://www.299792458.ru/news/2010-02-28-14 translate from RUS to ENG 1: https://translate.google.bg/translate?hl=bg&sl=ru&tl=en&u=http%3A%2F%2Fvrtp.ru%2Findex.php%3Fact%3Dcategories%26CODE%3Darticle%26article%3D2137 2:https://translate.google.bg/translate?sl=auto&tl=en&js=y&prev=_t&hl=bg&ie=UTF-8&u=http%3A%2F%2Fwww.299792458.ru%2Fnews%2F2010-02-28-14&edit-text= But if you can offer me icl7107 scheme to 500 degrees Celsius - I would be grateful
  11. hello I decided to assemble a simple scheme color organ - only miss one audio compressor into circuit diagram :) Can you help me with a diagram - signal i will take it from the output of the sound card on my computer. http://radio-stv.ru/?page_id=1942 lamp H1 = up to 100 Hz H3 = from 100 Hz up to 1 kHz H4 = from 1 kHz up to 3 kHz H2 = from 3 Khz to maximum freq.
