BTJ tone control circuit transistor (BC547) based on mono, stereo preamplifier PCB drawings are also made with solid is in addition TDA2030A Application, 2x15W there. The only source on the operating voltage of the control circuit 12v DC 18v DC but also said it will work with source: mirley.firlej.org/przedwzm_reg_tonow PCBs, an alternative scheme for all…
Main features of the Epson Cartridge Reset Program 1) Epson Stylus printers cartridges works directly with CSIC. 2) Reset or any chip using special addon device refreshes. 3) The internal ink counters freezes. 4) empty cartridges, reset internal ink counters. Color and Epson inkjet printers, powerful cleaning mode for the black-headed 5) separate cleaning. 6)…
Isis proteus before the SMPS circuit to the test with a very SMPS PWM control model of integrated, lib. I shared files, see: Proteus isis SMPS PWM Integrated Models Library Files TL493 TL494 TL495 this article TL494 there, but I wanted to get a separate article for the trio as the new TL493 TL495 Proteus…
Stereo Headphone Amplifier circuits specifically designed for the construction of the headphone amp circuit but none impressed me with its parameters of the output signal, thus I went into the design of the amplifier with discrete output stage and integrated exciter output stage. Nothing, however, is not free, so you can not always increase the…
Active subwoofer amp designed for use in the car cabin floor TDA7294 2SC5200 and 2SA1943 used, but the addition of an integrated output power to the output of this circuit is upgraded patlaşıl previously had different PCB drawing ; TDA7294 Power Transistor Output Power Enhancement Supplements TDA 7294 2x38v DC symmetrical supply is working with…
There are 3 USB converter circuits CP2102 USB communication as in the isolation section of the ISO7221 standard is being used. USB/RS232 adapters isolated TTL (RX-TX), isolated USB/RS485 adapter (+ max13488) usb1wir isolated adapter (+ DS280) All prepared with the USB adapter KiCAD source of PCBs, in addition to the schema files are picture. Psi…
USB PIC Programmer Brenner cool the market after our most used Pickit2 Clone programmer was … Previously quality Pickit2 Clone clone circuits have shared pickit3 output but two series still popular and the business sees the archives of different trasarım there but basically the same last review before, let me be 🙂 but operation of…
Author fluorescent deteriorating energy saving lamp electronic power board to assess these additional driver card have made objective robust power board with power LEDs (EDEX-3LA1-E1) to run … for that power board transformer addition to the 14-lap winding adds this already across the grid had enough space. Received after winding voltage-controlled MOSFET pointed the opamp…
Open source component library inventory software is simple and very handy and can be customized so that the usage area expands upon request materials added to the name, openness, as well as the computer in the datasheet file or datasheet internet connection can add materials can classify the business the bright side source C +…
LED lamp projects a similar application in this circuit LED strip groups directly 220v rectified operated sufficiently strip LEDs connected in series for voltage limitation does not need previous post as mentioned in 220v directly into direct use is not healthy but commercially using a bit in the lifetime depends on the condition, of course,…
