    Resistor Value

    I actually wrote a post about these, however I was not able to find any with a white 5th band. Here would be one that has a black 5th band. There is also often a more noticeable gap between the 3rd and 4th band. https://forum.digikey.com/t/when-your-5-band-resistor-is-not-a-5-band-resistor/1501

    Can someone tell me what this is please ?

    Yes, in this case you are looking header with male pins and the pins are factory installed in the housing.

    The picture is a bit fuzzy, however it appears to be a JST header BM07B-SRSS-TB(LF)(SN)

    Relay That Toggles On & Off With No Hold Current

    I would think there may be an easy way to do something like this with hall effects/reed switch. You would be able to momentarily turn something on or off with only a magnet. Might be a solution depending on the rest of the circuit?

    My Air hockey doesn't power up anymore? Need Help

    Start here you should have line voltage. Make its nothing to play with though. Make sure you have power to and through your fuses and on both sides of your filter. Next check your blower. Do you have power at your blower. If not work backwards and see if there is a seperate power supply for...

    My Air hockey doesn't power up anymore? Need Help

    So somewhere on your table you have a power supply similar to this. 3 lines are your input and 2 are your output. Do you have 110 coming in? Do you have power coming out? Start here!

    My Air hockey doesn't power up anymore? Need Help

    Do you have power going to the Blower? I am assuming this has a built in power supply that you checked the fuses on? Did you check input and output voltages? For the scoreboard are all the connectors secure. Is there is a signal going from the control board to the Scoreboard. Likely just power...

    Where to find data about LED 155BRP made by AND?

    The other thing is with a part like this you may not know if that is a MFG part number or a customer part number. Often when companies order parts from a manufacturer or a distributor they have the parts marked with their internal part numbers as that is how they are used in their own system...

    Dishwasher making a buzzing noise

    Locate and remove the piece that buzzes and replace it with a new one. That should remove the buzzing sound!

    Repeating Toy Hamster Parts?

    They do not work together. The first is a functional chip that would need circuitry and the second is a demo board that is the complete circuitry including the chip. The Demo board would be just about a complete solution needing only a power supply and a speaker.

    Repeating Toy Hamster Parts?

    It is not super easy for record and playback, however I seen it using a chip similar to the ISD1610BSY here is a demo board that may be a good place to start. I16-COB20

    DIY bluetooth speaker

    If you are looking to keep this waterproof for the lake you could also look at using a exciter. You could mount this inside the ammo box and get sound outside. Not sure how it would sound with the ammo box but they are fun to play with. Go to the 2 min mark in the video it shows him using it.

    help rewiring a electric fan switch to a alarm clock?

    First you would need a schematic of the alarm clock or take it apart and find out how much power you have going to the speaker. If it is enough you may be able to use this signal to trip a latching relay that will turn on an fan. If the signal is not strong enough you may have to look at a way...
