Channel Suggestion

There are Channels for all kinds of things from Art to Food to Laptops etc. I think a new Channel dedicated to Raspberry Pi would be brilliant! There's one for Arduino so why not RP?

n channel jfet

Can someone show me how to hook up an n-channel jfet transistor? My power supply is +5volts. Where do I hook up the load. I know the gate has to be negative relitive to the source( the source and the drain can be used interchangably, right), but I only have a positive power supply. I want to use an n-channel jfet because it normall conduct, right?I found this website: I don't get it entireleyI am thiisss close to understanding how to use transistors!

Dual-Channel RAM? Answered

I have a Gigabyte GA-H55M-USB3 Motherboard and an i5-760 CPU. I have been using 4x1GB DDR3-10600 modules, and then recently bought 2x4GB DDR3-10600 modules hoping to get 10GB, however, I can't seem to get it to work. All the modules are in working order and work individually. I currently just have a single 4GB module in. If I insert more, I either get a constant bios speaker tone indicating RAM error, or it will post successfully, but Windows will bluescreen. I have looked in the booklet and it is unclear as to how I should install the modules, but I thought I had to install them in matched pairs corresponding to the coloured slots on the motherboard. I have tried the 4GB modules in the white slots and the 1GB modules in the blue slots, but it won't post. Putting the two 4GB modules in a white and blue slot will post fine, but BSOD on startup. Any idea how I can get this configuration to work with my board? My CPU and board both support dual-channel DDR3 memory, so I can't see the problem here.

What's the difference between N-channel and P-channel?

I'm new to the world of electronics (though learning something new every day) and I've seen a lot of references to either N-channel transistors or field effect transistors, but I have been wondering what the difference is?  If someone could explain to me how the two are different in electrical characteristics, as well as in their applications, I would appreciate it immensely.

Help selecting a n-channel mosfet and resister

Hey guys! Been a while. . . Anyways I was looking for some guidance on selecting an N-channel mosfet, and also what resistor to use when I'm applying voltage to the gate. So I'm working some long LED strips, and I need the mosfet to be able to handle at least 7 amps, so I was hoping for like a 10 amp mosfet or so. I just didn't want to guy buy the first mosfet I found on digikey, I was just hoping for some cheap good options or popular ones. I needs to be able to do PWM. Also I don't know where in the datasheets to find the information on what resistor to use on the gate. For instance I see people using anything from a 1K to a 5K resister with a TIP120. How do you select that information? I will be using an 5v output from my Arduino.  So after searching ebay I found the IRFZ44N mosfet, 55v and 49A. I know this is way over my needed specs but I can get 50 of them for 10 bucks. Steal. Since it's so overrated what problems might I run into if any? Thanks guys! What I've found so far: IRF740 - 400v 10A

Youtube Ideas

I wanted to ask for some advice and feedback on my youtube channel as well as some new movie ideas. First off my Youtube Channel is very special to me and i think with the right work and attitude i cant get to to go farther: my youtube channel is Why the name Thelostrolo? well i created the channel when i was 11 (now nearly 15) and i thought i might as well keep the name! (I am working a big hunger games related project which will be uploaded to another channel) I am not sure if i should create a new channel. but that would mean starting from scratch and trying to get recognition again, but maybe you guys could help!? Anyway back to my idea: I had a phew ideas and of course ill need help as i cannot film on my own! The first idea is a simple idea called: 'The Confrontation" which is a simple action thriller type movie with gun movie effects and explosions! THe other on was: "Never look back"  a more serious film in which there is a kid who is bullied and one day is knocked out. He wakes up at home, but no-one was at home, so he decides to go out for a dog walk, he then comes across the bullies except they're afraid of him. etc etc and it ends with him finding out that he is not who he used to be! I could really do with some peoples feedback... not just because this took me a long time to type up! Also if you did check out my channel post your below and i might subscribe :D Thanks for the help Rowan Prosser- Rowans Movies - Thelostrolo RATE, COMMENT AND SUBCRIBE!

An Opps Purchase on Ebay Is it Salvageable?

So i have an 1998 dodge ram 1500 i purchase with no power options at all so i got power window regulators and replaced the door panels and bam I've got power windows. and since the door panels had lock buttons i bought some cheap 12v actuators off eBay and wired them up and bam. power locks.. THEN in all my creativity i was like i'll just buy an RF 4 channel kit and make it key-less. so i ordered this kit not realizing what type it was to summarize this kit requires you press one button to activate the a channel and press a second button to disable the active channel.. not at all what i was looking for.  Is there any way i can convert the kit i've already paid for into a momentary style. so as long as i'm holding the channel button down its active. ????  here are all the chip/ component numbers. 4x SRA-12VDC-CL 1x  SC2272-L4 - BD25D5D1 1x 9530FH~~~~~~ unreadable some residue on the chip a few caps a few resistors and an LED..  anyone think this is doable or should i just shelf it and get a diff kit?

HELP with P channel MOSFET.?

I've got a P MOSFET to connect some LEDs to 5v, regardless of where I connect the gate, the MOSFET (and the LEDs) always stay ON. Iv'e tried connecting the gate to 5 volts (on the source), to the drain, even to a higher voltage (13v) and nothing, current keeps passing through. I have checked my connections and pinout diagrams and they are all correct, but i thought that the MOSFET would let current pass when the gate was connected to Gnd and block it when it was connected to 5v (same as source), am I wrong? please help, i'm lost and i have found nothing useful on the web. PD i'm trying to control it with an arduino, and I have had no luck whatsoever.

Hey guys,  I have been thinking, and I am going to build some solar speakers.  Now this is not my first time building solar speakers, so I know how to wire everything.  The only difference is this time I want to want to build my own amplifier.  I want to build a 2 channel 60-80watt amplifier.  I haven't found any schematics online that are similar to those, and I would want to wire in an off switch, a volume knob, a bass knob, and a treble knob.  Also, I would want to wire in an 3.5MM jack at the minimum.  If anybody could help me with some schematics and a list of parts, that would be wonderful.  Also, if anyone knows how, is it possible to wire a USB port onto here that will not only charge the device, but would also play music from the device to the amp.  Any help would be greatly appreciated.

I think this one will work but im not sure. I think this will only work on printed PCBs if I can i'd rather have something i can wire up with ether perfboard or wires.

Transparent LCD - Alpha Channel Monitor

I'm working on a project for my MFA, and am trying to figure out how to hack some LCD's. The idea being that I need a screen that will simply display black or transparent, no colors, but it should be able to accept video input of some type. Hacking a tv or iPad seems the most likely route. The remaining image should show the ambient background through the screen with certain areas shaded according to the luminance or darkness of the video input. While I understand that with all of the polarizing filters applied, light transmission is less than 5% in some lcds, I don't know what happens if you remove the polarizing filters? I remember the old 'Tiger' lcd games that were quite transparent and high contrast, but they definitely didn't play any video! If anyone has any experience with LCD's and the polarizing filters, I'd love to hear your input. Alternately, if anyone has ideas on a video capable b&w; display... They all seem to be for medical purposes and are quite expensive! Thanks!

If I channel the hot air from my CPU cooler directly to the outisde of my case: good or bad to the system cooling? Answered

I think that if the channeling is done with a porr thermal-conductive material (i.e. plastic), I can get the hot air out of the case whitout having it mixed with the cold air coming from the outside. Besides, the PSU would still have its cooler running, providing more cool air from the outside and (i hope) preventing the cpu cooler from being overcharged.

I need a 48 channel Transmitter and Receiver Answered

As I'm searching I'm finding that most of you are extremely smat and very good at what you do. I have a dilemma involving R/C as well. I'm trying to build a 48 channel fireworks ignitor. As it stands it's almost complete but it's not wireless. Right now I have to plug a cord into an RCA jck on the board and the other end is connected to an electric match. I got all that. What I need help with is making this an optional "wireless" unit so I can stand back withmy guests at my party and ignite my fireworks from a few feet away. The problem is that the biggest R/F transmitter / receiver I found was only 15 cannels, and it was expensive enough that it wouldn't be cost effective to buy 3 of them plus and additional 3 or 4 channel to build it. I'm extremely limited on experience with eectronics and have no experience with IC's but I'm willing to learn if someone can pont me in the right direction. Thanks

Connecting/combining left and right audio channels together? Answered

Hi, I have something that can only take one channel but I am wondering if I can just connect the red and blue wires together in a audio cable so it will combine these both left and right channels into a single mono source (from the amplifiers point of view). Will this cause any problems with the audio source (phone) having both channels connected together like this? Will it damage the phone or anything like that? The main reason for doing this is the source (the phone) is stereo and some songs will have parts that are only present on one channel, which means that if it is not on the channel that is connected to my homemade lm386 based amplifier you wont here that part. Thanks.
