Hi all. I am trying to build a small cooler using peltier module 12706, as the image attached. i have connected the module to 12v 10 Amps power supply. the consumption of current is around 4 amps at 12v. also connected a Hugh heatsink with two fans on the hot side using a thermal greece, and a small heatsink on a cold side. the temperature on the
Using iron pipe, fittings and residential water heater elements I have made steam cleaners. They do rust up pretty quick. I like to ground the body to the source AC earth ground lead, but the heater elements seem to be pretty well isolated from the fitting. The heater elements are usually discarded with the hot water heater tank (I harvest mine
I am testing this gate drive pulse transformer circuit but the top 2n2222 connected to positive rail runs hot the ground one runs cool should they not have used higher current transistors to drive s coil?. and should there not be a 1k resistor on its base as well as the other if anyone can help?. 131870[/ATTACH
Hi, Does anyone have any experience of using a Eurotherm (PID Controller) to control the temperature of a hotplate? I need a steady rise in temperature (linear) when the hot-plate is turned on as well need a steady settling temperature (linear) when I turn off the device. Is it possible to do so using a PID controller? If so any ideas? (...)
Hi can anyone pls explain to me what is hot n well layer and what is it used for?? Meaning i had an error when i the source potential of my pmos was larger than the bulk potential thereby current flowing from source to the substrate. After i used hot n well on top of the nwell surrounding the pmos the error (...)
The Nwell should be reverse biased and the normal junction leakage will always be present. However if you manage to take the PMOS source above the well potential the vertical PNP may turn on and multiply the S-B injected current with some S-sub current @ gain (probably not much gain, but still). Drain hot carrier / impact ionization might (...)
hi to all i made a driver with l298 and it work well , i parallel two channel ... my motor was 24v 300mA .. but recently i made another one just like last one ,but in new one my l298 get very hot .. the motors are same ... i have both of them now , in older one my l298 work without heating and in new one l298 get very hot and
"We", Kemo Sabe? I'd say well more than half of the high reliability ICs I've designed, have been on bipolar technologies. You can break either one, but MOSFETs have classes of reliability problems (oxide wearout, hot carrier, NBTI) in -normal- operation that BJTs simply don't. Vertical BJTs, anyway - laterals are exposed to a lot of low quality
hello i have just installed a new heater into my desolderiron. i am a little worried, i hope someone can help. before i installed the new heater, the old iron was not working so well, the tip was stuck, blocked, it was quite hot; but i do not remember the heater chassis getting hot at all. but as i recently bought it se
Altium ver 9x Is there an easy way to assign a hot key to change the font of a net label? I would like to change from size 5 to 8 and add BOLD I'm familiar with the find similar objects feature however this does not work well because the font attributes of all the net labels are presently the same and I want to change perhaps 50 out of
dear all , i have a big issue , i made circuit using 8051 to control 3 phase AC (380Volt) motor speed using firing angle it's worked well , but the problem is the motor speed is changed by control firing angle which control also voltage , but in this case the motor become very hot after 4 seconds from starting. i asked someone and he told me
The scene we're trying to measure is how to tell the difference between a hot stove element 4 to 7 meters away from that same hot stove element with a pan on fire on top. (It is for a low-cost fire prevention device.) While the device feature a camera for flame recognition, we're hoping to assist this with a well chosen amplification of very
It is a copy of well known amplifier with one speaker, power of 40W and two modes: drive and more drive. Schematic and the board were drawn in PROTEL. It is a copy of the original board. Most of elements like mains and speaker
Hi, Cold refers to lower temperature hot refers to higher temperature. thanks, Shobhit
Hi Gasant, is the supply circuit getting hot? Can there be any short circuit just before LM7808?
Suggested PCB footprints are related to an intended assembly method. For prototype production or other special requirements - change them at will. For single side assembly, simple hot plate soldering should work well with the suggested footprint, I think.
is this for data receiver margin testing or loop stability margin test or noise test?? an All Pass Filter Design, microstrip, stripline or coax? switch depends on test?? Can you use hot carrier schottky diodes?
What's the position you want to apply? Opamp is always a hot topic for analog.
For Nwell resistor, usually it is hot Nwell (is not connecting to the highest voltage). So a P+ guard ring around it is needed.
I've been trying to do the layout of a differential amplifier as my first layout. I fixed all the DRC errors, but "hot n-well". I know that it means the n-well is not connected to vdd, but in my case I think I connected it to vdd as you can see in the attached there something that I overlook or should I do something else to fix the error?
Safe - No. Resistors, but they give no isolation, the voltage will vary with the current being drawn and they will probably get very hot. Capacitor, may work but again no isolation and regulation may be poor with a likelyhood of noise on the supply as well. Brian.
Hi every one, I have just built a 40V, 5A, Maximum Power Point Tracker, using a buck topology, and it works considerably well, especially for low sun conditions. I used P Mosfet for the switching, and complimentary transistors (BC639 and BC640) as the mosfet gate driver. My problem the Mosfet gets very hot at mid switching condition. H
Hi gurus, I am trying to do a simple inverter layout, when i run DRC i am bugged by this DRC error of Info: hot nwell. vdd! is labelled on to the M1, so thats not the mistake i have done ! I dont have any clue absolutely how to solve, Any help is highly appreciated. Regards, santini
Hello, Basically you get the error as hotnwell if the nwell is connected to some other supply otherthan vdd. You can ignore this error if the desiner issureof the well potential or else youcan eliminate the error bychanging the well potential to vdd. Regards, Sridhar.
A very cheap poor quality soldering iron does not solder well. It gets too hot which causes its tip to corrode and to burn away the important flux. My soldering iron is about 44 years old (a weller) and has temperature control so it is never too hot. Its tips are plated and seem to last almost forever.
Hi What are the hot topics in Information Theory,nowadays? Thanks
4 state one-hot = 0001,0010,0100,1000 4 state zero one-hot = 000,001,010,100
it is a really hard question , PLL specially for frequqncy synthesis was the last few years one of the hot topics in research , and i think it will continue for sometime as well ppl now think , in making the PLL more and more getting wide band, low jetter "phase noise " and so on , and no RF or even diditgal chip don't have a PLL khouly
select topic on SIP which is voice based and hottest protocol under implementation. refer rfc 3261
Dear all, I have an equipment with rs232 output (TTL level with 5V power source). I made a adapter to connect that equipment with PC use max232 transceiver. When the adapter is cold plug, the board work well. But when hot plug, the transceiver IC became hot and can not work. Could you suggest how to solve that problem? If we use (...)
hot tub can be because of small distance between the tub and the other wells than the well where is placed . If you will told us what technology and the software you use maybe will be more simple to find the answer :)
well, your high third harmonic is coming because of the glitches in the DAC. I do not understand why the second harmonic levels are high in a differential DAC (as pointed by So, take care of the timing of the switches. What is the segmentation ratio you have taken ? More importantly how is your INL? If
i have decided to work on cdma for my final year project... so any body can please help me out in deciding the topic for that... well, I did my master thesis on "Investigation and FPGA implementation of predistortion for future UMTS LINC Transmitter". It is linearisation method and currently hot topic in 3G industry as we

P-substrate offers better control on hot electron effect...
You can solder it with almost any station, but definetely you'll need a pcb with solder mask, some flux material, very well controlled ammounts of solder material, and what's most important : good hand and experience. You can also solder it with hot air station, but you'll have to be carefull, the plastic from the connector is very sensitive to ove
well guys first of all this section is not designed for projects, its for professional problem. you need to upload it in the projects section. anyway. better that u start seeing CDMA reserch papers. hot topics are multiuser detection as far as i remember, joint detection techniques etc, but better see IEEE papers available at elektroda then decide
well, considering intel's commitment to Viiv, wireless security is a hot topic nowadays, at least for WiFi. It is not only WEP, WPA, MAC Filtering, Null SSIDs, etc... even additional IC's are becoming a requirement for generating real (not hard-coded software solutions) pseudo random numbers. It is obvious that wireless security has a future ahead.
Maybe you can try the latest one - SUSE 10.0. It's very hot recently.
DSP with FPGAS is a hot AREA .. a lot is going on ! But one of the problems is how to IMPLEMENT floating point algorithms .. well there is HSLA a library that you can get here : you still need celoxica .. with this any DPS application now is stright forward !
Excuse me Which one do you want to know?The hot N-well or the Dummy Layer? Regards flyankh
well I decided to take a stab at resoldering SMT's but it didn't go as plan. (See pictures). I am using a hakko style hot air soldering tool. I apply flux to the SMT then use the hot air tool to heat the SMT then pry out the smt. Some of the traces on the board get's damaged. Is not preheating the board causing the problems?
well tell me excatly which subject ur interested in i shall suggest some interesting topics.. there is VLSI system design, there is VLSI Signal processing, Low power CMOS/VLSI, Analog VLSI, ASIC Design, Analysis design and Simulation implementations n these topics.. the current topics which are hot are generally SOCs. Computer architecute side
Usually, hot n-well in nwell that is not connected to VDD. You should check that the Nwells are connected correctly to VDD. If you want to connect the nwell to different potential,I think that you can ignore the warning.
The question was what is the TREND in the electronics industry ,Probably you mean what is hot in the US and abroad .. But mainly in the US .. well very simple question NOTHING,everything is in stand by .There are of course the big monsters MICROSOFT ,INTEL ,XILINX ,IBM ..well they always sell their stuff ,But the telecom is deadly slow (...)
