    Solar Drone

    Just looked up a mini quad, weighs 15 grams with lipo battery. Flight is "about 5 minutes" and we all know how quick this goes when we actually time the product. Battery is 200mAh so I'm estimating around 1.2A draw on 3.7v (voltage deminishing as flight time increases) One of the solar panel I...

    Apprentice Resume/C.V. - Include website and Youtube channel?

    I don't think a potential employer would want to go trolling though web sites to get to your information. Would be much better to provide whatever detail you can give.

    Need electronic help with a custom transmission shifter

    Your actual selector shows 5 position but your diagram shows only 4. However, one arrangement would be a microcontroller, with each of your selector terminals going to a digital input. Servo output with position based on a pre-programmed output position. That would be just a starter. One would...

    Wiring Batteries?

    From your initial query it appears you are unfamiliar with many aspects of electronics. It would be a very good move on your part to do some online reading on the use of and the protection equipment necessary with LiPo or with LiFe cells. Any battery can be dangerous at times but these type...

    Hall effect ignition

    Diode protection or rather spike suppression is fine when associated with relay coils, solenoid coils etc. where any inductive flyback voltage is generated when the coil is shut down. Any voltage produced here is viewed as unacceptable because of the noise and interference it produces...

    RS Analogue Multimeter AMM301

    Are the 2 x AA batteries installed the right way around? Also looks like green corrosion on the bottom left cell. How about the fuse? Also this is a bit confusing "but the other rx1K, x10K dont move needle and when it does move "

    Hall effect ignition

    Contributor "Debe" has had a lot to do with ignition systems.(writes into here at times) As far as I know mainly magnetos in the write-ups I've seen at least. If you think the diode is essential then it must be fast. Still think you are not grounding your secondary properly. One Debe...

    High-end drones

    Find out your countries regulations. If as in Aus, CASA actually provides a free app that shows if you can fly at your current location as well as the current laws regarding use. I fly a lot of other gear as well and it pretty much goes without saying to get some insurance cover. There used to...

    Beginner circuit problem

    Getting the LED placed the right way is not a difficult task, nor working out the correct current limit resistor. Connecting an incandescent bulb in the output could well fry the chip. Maximum output is usually around 200mA. ( that's milli amp or 0.200 amp)

    What polarity is this?

    I'm wondering if the Op is referring to the RCA socket.

    Beginner circuit problem

    Technically there are, however it is not used much. (milliFarad) There are instances where confusion comes in when cap (especially larger ones) are marked with MF or MFD in place of uF.

    Beginner circuit problem

    Your resistor combinations are beyond the recommended minimum levels for operation. No resistor on the LED causing high excessive current to flow. Online calculator here for easy calculations...... https://www.allaboutcircuits.com/tools/555-timer-astable-circuit/ A free online book on 555...

    Who knows how to test N-Ch. MOFETS with Multimeter? Please HELP!

    I've seen a couple of those that will not work, perhaps not high enough bias voltage. LED and a battery seems to work but I'd be inclined to use a resistor on the LED.

    Looking for help designing a timer

    Stop watch has many of the functions. Maybe hack one of those. For $5.00 I'd say worth a try.

    What is this?

    Photo did not come up. I'm guessing a regulator.

    Who knows how to test N-Ch. MOFETS with Multimeter? Please HELP!

    I tend to use an old analog meter on Rx1 for tests like this.

    LED for electric heater (UK)

    Usually any 240v rated LED will come with a high price tag. I've seen Clipsal units at $40.00. Neon units come in at maybe $3 or $4 depending where you get them. Neon is about 10 cents and a resistor maybe 10 for 10 cents.
