In the car Frost Alarm (warning sound) , outdoor lamp, alarm, temperature, battery voltage, date, overcharging of information, such as a pic16f873 microcontroller which allows it to be displayed on a LCD display 4×20 with lm335z temperature detection circuit design was achieved… as the sensor is being used. By the way I am now I…
It’s an interesting project I’ve seen in a project that is usually done with electric drills handmade shared a sawhorse; Dremel 4000 handmade sawhorse, Proxxon Made by reference to the sawhorse and circular saw for cutting PCB Assembly Sewing machine tuning, the author attached to the needle section of the machine and have mounted the…
Previously LM2575 (1 amp), and the LM2576 (3 amps) switching regulator ICS sharing about applications that have been LM2575, LM2575 high power mosfet to increase the output current by adding the received power regulator circuits of this type are usually integrated in the upgrade I wanted to share, it’s no wonder. Note: without pictures I…
Complete car amp in a project stk4131 amp solid-II solid KA3525A DC-DC converter (SG3525) is located in the Filter section based on the bass opampli also tl074 DC-DC converter, the primary windings of the transformer circuit used; 2×6 2x type 9 secondary species (connected in parallel with wire Section 2 1mm) of the circuit diagram…
the Battery Charger circuit (lead acid SLA) L200 regulator chip on the circuit board resistor and the diode on the positive 1.3 Ah or 7AH batteries or you can charge with the change of the commutator of the PCB and edit the drawing, by adding the jumper, you can make gradual Proteus ISIS Proteus Ares…
Control circuit designed with microcontroller is done with high voltage to incapacitate an interesting insects pic16f675 a bug it won’t run in normal operation for power saving high-voltage circuit on the PCB when solid comes in contact with the cage on the floor your running high voltage low current dcdc pic16f675 ceiric: the circuit assembly…
Circuit used MOSFET N-Channel CSD18534KCS. I don’t think would be found in the market that may meet or beat irfz44 MOSFETs used can be different from R1, R2, R3 4.7 K resistors Extension Led Strip source: grix.it/viewer.php?page=11466 alternative link: FILE DOWNLOAD LINK LIST (in TXT format): LINKS-25457.zip
PCB printed circuit board lamination machine with pvc prepared at the end of the video on preparation of the practical printed circuit, solder in a manner that is rapid PCB coating is a useful method that I used when I was shown… in this video, tin coating PCB lemon salt and had been informed about…
300W RMS power amplifier PCB drawing in the design of very high quality, very good but a complicated circuit layout + PCB drawing double-decker to be taken to the archive, though I don’t recommend it for beginners the value of the Operating voltage with symmetric +- 75v max. 80v overload, short circuit protection and preamfi…
the Viper22A ICS with PWM control built on 350mA power LED driver circuit without insulation, without the use of the transformer was achieved. Design of series-connected 1W LED 350mA output current is limited to 3 pcs made to run. Input Voltage: 90 to 265V short circuit protection between. note LED driver capacitor connections caution notice…
