    I intend to start a project to build an amplifier, preferably a replica of a TWO ROCK amplifier. However, I don't have technical plans and I don't have enough knowledge to perform this task. For this reason, I ask for your help to succeed in this…

  • Breadboard

    I have been thinking about the following: I'm disabled with a couple issues, my wife has been helping me breadboard because my illness makes it hard for to build circuits due to my coordination (eye hand coordination). My wife and I have been talking…

  • Simple circuit to create a spark

    Hello, My small torch spark mechanism is broken and I was wondering if I could create a spark with an electronic circuit. I use this torches daily and it's been the 3rd that got broken and you can't really buy spare parts for these. I'm not sure where…

  • Trying to find a high-speed, high-power transistor to use as a switch

    I'm designing a high power H-bridge circuit, and I'm trying to find the best transistor for the design. The most important parameters are that it has - 10MHz switching speed frequency - Low on-state resistance - Low off-state capacitance From there…

  • i want to test my obd devices esd with dso actually i have types of esd but both are showing exactly same waveforms in dso moreover that how to test esd with dso

    I have three types of ESD mentioned below 1 ESDA6V1SC5 having 5pins 2 ESD5V0L4UG having 5 pins 3 ESD2ETH-D having 6 pin so then concern is that i want test them that how effective they are or which types suitable or efficiently in my application…

  • Latch ciruit Design Problem/Sugguestions

    Hi! I'm working on a project which needs latch circuit in my design, which use for Power on/off by hardware and software... VBAT is 12V. so I put it through a LDR to logic 3V3. First I have a latch switch, when logic 3V3(pin2) connect to pin1. The…

  • Digital LED Counter Wiring for Thru Beam Sensor

    Hello, I recently bought a Reflective Infra Red Sensor and a Digital LED Counter for a packaging line. I wanted to know if I can wire a thru beam sensor on the same counter as that would fit the packaging line better. Attached on this post are images…

  • Electret Mic "Splitting"

    I've got a Baofeng UV-5R . I've done some research, and I can see how its mic/headphone plug is wired . It seems to me like it expects an electret mic as the element. I've got a a Rexon RHP-530 airband radio. I am pretty sure it has the same wiring as…
