Type of diode

Hey everyone, I recently had an ASUS laptop to repair and after troubleshooting, found some damaged components among which is this surface mount diode (kindly see picture). I looked around for a datasheet but cannot find anything. Am also unable to find out exactly what type of diode it is from its code marking. I've had results varying from a 'leakage diode' to '3.3V zener diode'. However, I am suspecting it might be a schottky diode since it was in what looks like a boost circuit. Any help would be greatly appreciated. Code marking: 100 98FP1  j Thanking everyone in anticipation. Kind Regards, Nawaz

Hand-held typing device - UK - Mid 1980s.? Answered

Back in the 1980s I knew someone who used a hand-held typing device which worked by pressing 5 keys (one for each finger + thumb) to form characters.  The stored text could then be downloaded via (I think) serial link to a PC.  He used to infuriate lecturers by appearing to be sitting idly and not taking notes when he could actually operate this device at normal speaking speed and could print off a whole lecture transcript afterwards. What was this device called and who made it?

Looking for a type of switch

Hi People of Instructables! I hope I am posting in the right place. I am looking for a switch that when you walk pass a point it shuts off and when you walk the other way past that point goes back on.   For example... I have a flash-light in my hand, when I walk through a doorway into a house the light turns off.  I go through the doorway the other way (to the outside) the light turns on. Conditions: It has to be able to do this through cloth as the flashlight could be in my pocket. It can only work when you walk through the doorway but not when standing near the doorway Does anything like this exist?  if yes what is it called? I have been searching the 'net and not been successful as I don't have a clue what I am looking for. Any help would be greatly appreciated. Thanks for reading my post! TheLastPrincess

What's the name of the type of switch then works by rotating it, and you can keep rotating it on one direction.  Like the kind of switch that controls the volume in a car.  I'm assuming that every click switches between being it conducting and not conducting?  I need to use one with a micro controller (I don't want to use a potentiometer because they can only rotate so much) and I need to know the name so i can buy one.

About electrolytic (aluminium) capacitors..... what do the low ESR ones do that normal ones don't? And how come they have these capacitors in bipolar types, but not all are bipolar? Is it because of the size/cost?

Which type of computer is best?

Ok, so my father has offered to pay for HALF of a new computer. But which type is the best? Macs are very aesthetic, but expensive. I also would be dual booting it with windows. PC's are cheaper, but sometimes that also reflects in the hardware. My only requirement is that it be gaming compatible. Big monitor, if it's like a iMac and has one built in. High performance graphics. I'd like atleast 4gb of memory, but 8+ would be delightful. Harddrive space isn't really an issue, since I am currently using about 60 gb. I have something like $400 right now. I could probably make that around 800 - 900 by the end of the summer. So a Mac is defiantly a possibility. Also, I'm a student so I get a $100 dollar rebate from the Mac store.

Motor type / Arduino control

I am looking for a motor to control via Arduino. I know such a thin exists but am not sure exactly what it's called. Basically it is a motor but instead of rotating a shaft it make the shaft go in and out. It doesn't need to apply much pressure just a little tap. I thought it might be called an actuator and is similar to a solenoid I suppose. Any idea where I would find such a thing, what it would be called and how to control via Arduino. Thanks. Phil

type of soldering wire use

Hello, I have a 60/40 rosin core solder wire. Then I use a 220V soldering iron. Now whenever i tried to melt it, it took short while. compare to those wire in which you can melt it by only touching it with the iron. It's because i tried to repair a headphone jack and I still got where to solder it. Top - Green 2nd - Blue 3rd - Copper  4th - Red It was based on its current solded positions between the thin wires and the 3.5mm jack. now I'm asking what kind of wire do I use. I saw other video tutorials on how to repair a headphone and whenever they solder it, it was a spot on. Thank you.

Are tube type amps really better than solid state type amps? Answered

A question below reminded me of this. My friend and neighbor plays a guitar and has been going on about how great his new Fender tube amp is and how much better it sounds than the solid state amp he previously used. Truthfully, I've listened to him play on both (he's no Chet Atkins for sure) and I can't discern much, if any difference. I've done a little research and heard words like, "warmer,"  "more vibrant" and "louder" used to describe the difference. With the exception of louder, most of these descriptions are not actually measurable. Is there a way to definitively say tubes are better, or is it just a subjective quality that depends upon the ear of the listener?

Different types of motors on the same arduino?

So I am still learning Arduino but I've already built quite a few robots. I'm stepping things up a notch by building a robot with several motors. I am using 9g servos, stepper motors, standard servos, and regular dc motors with l293d ic. I am also using 2 ultrasonic distance sensors. There will be 14 motors in all but I think Arduino Uno can only handle 12? I will be using an Arduino Mega, so will that be ok? I also want to know if you can put all these different motor types on the same Arduino and if it is possible, would writing a code be really complex?

Make a mechanical typewriter type to a text file?

I've got an old (circa 50-60's) mechanical typewriter that has a great deal of sentimental value to my girlfriend. Her grandfather was a writer and was always glued to his typewriter. And since I'm a huge nerd I came up with this crazy idea. My plan, and hopefully this can come to life in a few years is to modify (and not break) the typewriter so that it will send text to a file that is typed out on the typewriter. I've seen the tywpewriter, but they use an electric one and it types out tweets that are found on their twitter account. My idea is to use the typewriter as a guestbook in our wedding. People will come in and type on nice pretty paper so they can see what they're writing, and we'll have a text file. I'm pretty much settling for a text file or some sort that I can use later to modify. I'm thinking I'll have to scrap a keyboard and make small solder pads for the metal keys to make contact to. Any ideas where I can get started? I'll post pics of the typewriter when I take some, but for now, just know it's mechanical and not electric. TY!
