  1. They are mostly registering as a plain user, they pass the question, automatic Spam Defense which flags the accounts with spam score and they also approve their email address which is new each time.
  2. I have now added: "How many color bands a typical resistor has?", let's see how it goes and if this guessed easily i will replace it.
  3. Yes it seems so, any idea for an electronics related question?
  4. This feature is enabled on our community but seems spammers get new way to register and post. We keep a close eye on the situation.
  5. Here is another forum topic discussing this power supply. (in Russian) http://forum.cxem.net/index.php?/topic/209045-бп-на-tl081_0-30v-0002-3а-и-его-модификации/ Translated Link: https://translate.google.com/translate?sl=auto&tl=en&u=http%3A%2F%2Fforum.cxem.net%2Findex.php%3F%2Ftopic%2F209045-бп-на-tl081_0-30v-0002-3а-и-его-модификации%2F
  6. SeeedStudio is supporting the maker with this great offer! They will assemble your PCB (5 pieces) for free. You just need to purchase the parts and place the order online. More information: https://www.seeedstudio.com/free-assembly-for-5-pcbs.html
  7. Thanks for attaching the Gerber. Could you give us more information on the rating (votlage/current) of the heating element as well as why this is needed on 3D printers?
  8. I looked around for such a charger, but seems difficult to find a suitable circuit for such high current output. Let see if someone can come up with a schematic.
  9. take a look at these 3 phase motor controllers, http://www.electronics-lab.com/project/3-phase-ac-motor-controller/ http://www.electronics-lab.com/project/inteligent-power-module-ipm-board-brushless-motors/ What kind of motor is yours?
  10. Could you provide the design files or Gerber files, otherwise this is not usefull for the members of the community.
  11. Here is the project page: http://www.electronics-lab.com/project/power-supply-brushless-motor-drivers/ This board produces 400V output to power Brushless Servo Drivers, mainly IPM Modules. It is not able to drive the motor. For this purpose you will need a driver board. We can produce this board if order quantity is > 25 pieces. If this interests you, i can quote for that. An Arduino can be used to produce the control signals for the control board.
  12. This is the basic connection of BMS charger circuit. Do you need the scheme for the charger it self maybe?
  13. This power supply is also published on an old Czech electronic magazine attached here. and here is also two nice builds of this PSU: https://translate.google.com/translate?sl=auto&tl=en&u=paja-trb.cz%2Fkonstrukce%2Fzdroj.html and here: http://diyfan.blogspot.com/2012/02/adjustable-lab-power-supply.html 0-30V 3A PSU.pdf
  14. Hi there, These capacitors are filter ones and need to be placed in various spots on the board, near voltage inputs, outputs, IC power pins and other place, so they filter the noise on the Vcc line across the board, so that's why they are many and connected on main voltage. 1n5422 diodes (Schottky diode 40V 2A) are used to protect the ICs from reverse input voltage on their Vin pins, as they allow current to flow in one direction. You can use any Schottky diode with same characteristics. Welcome to our community, Mike
