    Bottleneck 555's 0.2A Stuck project

    China PWM arrived :) and works superb !!! Operating voltage: DC6V-90V PWM duty cycle: 0% -100% Control Power: 0.01-1000W PWM Frequency: 13khz Quiescent Current: 0.005A (standby) Fuse type: 15A Where are the wirings on the back of the pcb. There is just solder visible...

    Bottleneck 555's 0.2A Stuck project

    After a lot of searches I might have found something. Thumbs up ! Will this work on 6V(and also with 12V) ? 2SK2498 50A 60V :D http://www.uxcell.com/50a-60v-nchannel-mos-field-effect-transitor-2sk2498-black-p-148579.html http://www.datasheetcatalog.org/datasheet/nec/2SK2498.pdf Datasheet RDS...

    DX.com uses China Post it takes 2-4months compared to Hong Kong Post's 2-3weeks. + I think DX lies on that 6V if it only takes 10V then I would have a 12€=15.20$ PWM that I have no use. It is a high risk. :( (also no valid discount coupon codes now :D ) How to cool off these small SO-8...

    How this PWM works on 6V ?(It probably has a MOSFET+a 3-Leg Diode+What's the third TO-220[a voltage regulator ?] ?) http://dx.com/p/dc-6v-90v-15a-pwm-motor-speed-control-switch-governor-green-black-160094

    Bottleneck 555's 0.2A Stuck project

    So far I have solved the controlling of 12V DC-geared motor. :) Big thanks !!! (I can run it now with minimum input of >9V battery) But adjusting the speed of a small toy 6V motor 0-100% with 6V input looks like a dead end. (It is so small that I thought it would be super simple :o )...

    Bottleneck 555's 0.2A Stuck project

    Hhmmm. that PNP-transistor was one of the smallest ones.(link of list) http://www.futurlec.com/TransPowerTIP.shtml I see NE555 makes max. 0.2A and transistor needs 0.375A to work. Datasheet: TIP32A VCE(sat) IB=-375mA Now I only need a transistor which has IB=<-200mA. Is there any...

    Bottleneck 555's 0.2A Stuck project

    I have an idea I'll create an own similar PWM for the 6V motor. Using TIP32C... I=3A (PNP-Transistor) And I'll just use the same circuit drawing from mosfet to it....(Is it ok ?) This way I can run the 6V motor with 6V batteries without breaking the 555:

    Adjustable DC power supply circuit: Below correct ? What is a cheap & reliable DC power supply to buy ?

    Bottleneck 555's 0.2A Stuck project

    I often have brain farts (I changed "half accidentally" all) - How much "noise" 12V motor makes in volts ? (or a 6V motor ?) IRF2804 mosfet would only run on input voltage of min.9V so it's good only with 12V motors but not when I change supply&motor to 6V... Solves only half of my "driving...

    Bottleneck 555's 0.2A Stuck project

    Now the plan probably is ready. (All "about" minimum rating components) All wanted options are there:(when the right mosfet is found...) INPUT VOLTAGE: 6-12V LOAD'S CURRENT DRAW: max.10A When this pwm is ready. I'll make a wireless one with remote control... ;) .

    Bottleneck 555's 0.2A Stuck project

    I made a better picture. No imaginary amperes just wires mentioned: :D I ordered a 4.5€=6$ China pwm to look how they make it... http://www.buyincoins.com/new_en/details/new-10a-dc-12v-24v-36v-motor-speed-pwm-control-controller-dc-motor-driver-product-16105.html It says: Input= 12V...

    Bottleneck 555's 0.2A Stuck project

    How about now ? (Changed 0.2A to 10A...Does it break the 555 ?) Planning about wiring+amperes and where to put small AWG10 and large AWG20 wires ? I have no idea where runs the paths of low 0.2A(NE555 current) and Load's high max current...

    Bottleneck 555's 0.2A Stuck project

    OK. I think I got now the different current paths right. 10A is not constant current. I don't know how much below motor takes if it stalls... (=Too much force to opposite direction that causes motor to stop or move much slower) So I want to be safe about "high current spikes" if something...

    I use Germany Ebay.de because there is no official Ebay.xx in my country. I live in Northern Europe :o Final ratings:(I might just go for 9V-12V if I don't find VGS=6V) VGS= 6V (Input voltage) Rds(on)= <10mΩ=0.01Ω (Dependent on power+current) ID= 10A...
