    Questions regarding capacitors

    Hi, if the energy has some where to go, like an inductor you can have a coil gun ...

    not exactly an electronics repair.. need advice

    That's it! just take care about the cap's they are not polarized type. The inductor is almost bullet proof compared to the crappy electrolytic caps. Olivier

    Regarding Depth Calculation

    Hi, You welcome Naseer ! No, nor the depth, the distance, or the altitude. Maybe having accelerations in known (or measured) time can act as depth indication, not a real measure however. Olivier EDIT: Well you talk about survey not drilling, so maybe you can characterize the winch resistance...

    not exactly an electronics repair.. need advice

    Hi kneedeep, Sharp pictures of the components can help us a lot to identify them. Indeed the involved voltages are very low, no need to worry about at all. Olivier

    Regarding Depth Calculation

    Hi, Sorry for the post bouncing, just want to find out if it was a homework. The IMU platform will only provide you attitude indications. To measure the depth you can use (a well calibrated) pressure sensor, maybe a ultrasound, radar or laser ranging equipment. This to have it independent...

    Speaker cabinet switcher

    Hi Donkey, yes it will be better for the loudspeakers but we still must care about the impedance "reduction". Can also be both contact before break and unshort a temporary serial load to relief the amplifier. Olivier

    Regarding Depth Calculation

    Hi, My question was not linked to any IMU manufacturer. With any type of accelerometer,magnetometer and gyroscope do you feel that you can calculate the depth ? What the final project will be? A model submarine? Olivier

    Anyone seen these connectors?

    Hi again, others guys to contact as the RM (Rubber Molded) range looks close to yours http://seaconworldwide.com/products/electrical-dry-mate/rm-rubber-molded/ see 7 pin ones from page 30 http://seaconworldwide.com/wp-content/uploads/RUBBER-MOLDED_lres.pdf Olivier

    Speaker cabinet switcher

    Hi, don't know for online tutorials Bert, but relays and switches can be classified as basic electrical components (so you can Google accordingly) . controlling the relays (in your application at least) can be more classified as electronics. You can also maybe ask here...

    Speaker cabinet switcher

    Hi, having any amp connected to any cab is more touchy. It will look more like a 3 by 3 matrix mean that 2 amplifier output can be connected together, very bad. So it only can be done safely with a relay/switch combination and a bit of electronic to avoid any forbidden combination. Olivier

    Custom DJ Karaoke Mixer/Scratch Pad/Laptop

    Hi Chris, Your schematics are not that bad (need to walk before running right!) but we can go for the linked mixer if it's map you needs and having fun anyway. All parts are common (I just suggest again to use dual op amp everywhere, so TL062 or TL072 here) this will make you shopping list...

    Speaker cabinet switcher

    hi Bert, A (high current rated ) 3 way switch can indeed be used but you must never switch speaker cabinet when playing or bad things can happen to you amplifier and/or you speaker ! better to stop sources and reduce the volume to 0 before. Having more than one cabinet used a time as...

    Regarding Depth Calculation

    Hi naseer39, Welcome to this forum ! Already having calculated Pitch,roll and Heading do you feel that any of the IMU sensors is able to help you in the deepth calculation ? Olivier

    Atmega8L using 3v Battery

    Hi, The are way's to improve the battery live. jackorocko estimation's applies for a continuous usage. But, depending of your application you can: -Wake-up your circuit at fixed interval with a timer to have maybe few % of active current (discontinuous usage). -Add a large (low leakage...

    Anyone seen these connectors?

    Hi avalon991, maybe knowing the product where the connectors are used can help us. It' s looks very particular sealed but not latched. Maybe others connector can match but the pin alignment is not common, also must be the same spacing, pin diameter.. Is there any marking, logo or something on...

    Custom DJ Karaoke Mixer/Scratch Pad/Laptop

    Hi , Looks almost OK Chris, nice. QUOTE: So in lamen terms,, there is only 1 LM358,,, the audio input passes through on one side, the out through No 1, then goes through the 3band eq then passes through the chip on the other side and ends up finalising the output through the pin 7 (out 2)...
