    CCD's and CMOS image sensors

    yes, your completely right elix, thery're really expensive at the moment, ive taken to disassembling webcams, salvaging both the electronics and the included optical assembly, even though the ones i have been able to get hold of are fairly crap quality. ::) what experience do you have in this...

    CCD's and CMOS image sensors

    hi, ive been searching the net for ages, for a good chip, and this is the closest i have got to what i need; TC246RGB-B0 on Texas instruments website: http://focus.ti.com/paramsearch/docs/parametricsearch.tsp?family=analog&familyId=373&uiTemplateId=NODE_STRY_PGE_T and the datasheet...

    German diode translation?

    hi, the datasheet is a paper copy that came in the bag, and I have no scanner to show it to you, but to be honest that was the only thing i didnt understand. (it is just a list of what is included listing part numbers, type of diode, and voltage/wattage, not a detailed datasheet of an...

    German diode translation?

    hi, anyone speak German here? what is 'Gleichrichterdiode' I bought a multipack, of diodes and got a german datasheet. no online translators translate it, think it might be rectifier diode? thanks :)

    CCD's and CMOS image sensors

    EDIT: im probably going to use CCD to be honest, because they have higher sensitivity, higher quality images, lower-noise, and generally more pixels (not a really important factor for me, as long as it is above 2 megapixels) even though CMOS sensors, can consume about 100 times less power, and...

    CCD's and CMOS image sensors

    hi, dont know if this in the right forum: for a low end image sensor (between 2 to 3 megapixels) in a colour video application, can anyone recommend the best sensor to use (CCD or CMOS) when i say 'best', i need these specs: >smallest (dimensions, and weight) >2 to 3 megapixels >low...

    hydroxy gas power supply/separating oxygen and hydrogen from water

    hi, platinum is the best material to use for the electrode as its an inert metal, but obviously, this is too expensive for a homemade plant. as long as this black 'stuff' is not reacting due to the electrolysis, and causing too much unwanted, impure gas to be formed along with the hydrogen...

    hydroxy gas power supply/separating oxygen and hydrogen from water

    ok thanks, just wanted to be sure that i had the basic design right before i go further. im gonna try and salvage some graphite electrodes too and clean em up:) ill get back to you when i have built something worth posting

    hydroxy gas power supply/separating oxygen and hydrogen from water

    how did you set up the actual electrolysis chamber? This design is pretty good i think reaction_chamber.zip

    hydroxy gas power supply/separating oxygen and hydrogen from water

    hi steven, Ive read an article about this experiment, where the woman suggests using graphite electrodes that she has salvaged from some kind of battery. perhaps this material is less seceptible to corrosion from thie mixture. I think adding salt to the water does not increase the yeild of gas...

    hydroxy gas power supply/separating oxygen and hydrogen from water

    hi steven, ive started building the main electrolysis chamber out of some plastic piping:) I found a useful fact: adding salt to the water improves its conductivity, and increases the yeild of gas, monoman

    hydroxy gas power supply/separating oxygen and hydrogen from water

    Hi steven, Thank you for all of this, much appreciated, there is more than enough info to get started with, please if you add/change anythink else, keep posted, monoman

    hydroxy gas power supply/separating oxygen and hydrogen from water

    thanks alot for those schematics! can you provide me with the information about how to set up the actual chambers, e.g. where the water goes in, where the hydrogen gas comes out, and all the chambers in between, along with the process of each one? this is alot to ask but maybe you could direct...

    hydroxy gas power supply/separating oxygen and hydrogen from water

    hi, this project is brilliant!!  I never would have thought of using an arrangement like this in the house, supplying you with hydrogen gas to burn. I could use this in my boiler and hob, maybe save some on the gas bills!  :o do you mind posting the circuit schematics for it, and any other...

    spark energy?

    thank you for the very quick reply, but it is the energy of the spark that i am trying to calculate.

    spark energy?

    can anyone please provide me with a formula to calculate the energy of a spark between two terminals of a spark plug? (in relation to the distance between them, and the voltage across them) thanks for any help

    transistor as a switch

    hi, just wondering, what does this circuit do? is it just to change the output voltage of the 555? if so what does the transistor for? thanks for the help.

    digital question

    the way I have always built a half adder is to use an XOR gate and an AND gate. usually I will build the XOR gate by combining an AND gate, a NAND gate, and an OR gate. i dont think it is possible to build a half adder purely out of NOR gates and if it is I imagine that the circuit would be...
