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

I'm working on a project and I needed to get a PCB made. I was planning on getting it from BatchPCB, but I ran into a little problem... I'm using a NAND Flash chip, which is TSSOP48; the footprint has 6mil spacing! (BatchPCB has a 8mil minimum) The next cheapest solution would be Barebones PCB, which makes prototype PCBs without soldermask & silkscreen. I'm worried about soldering on the Flash chip, and another LQFP48. Will the lack of a soldermask make it impossible to do?

Hello, I recently had a tablet to repair and this SMD IC was damaged: "C03AE". I can't figure out exactly what it is. Results I got range from LDO to Power switch to overcurrent protection. Does anyone know or have the datasheet for the latter? Its SOT-25 package. The tablet works fine without the IC (can charge, work on wall adapter only, etc). Here are some voltage readings WRT to ground (pin 2) and battery at 36% charge (pin numbering as per picture) Case 1: display ON, charger not connected: Pin 1, 3 and 4: 0.00V Pin 5: 3.64V Case 2: display OFF, charger not connected Same as case 1 Case 3: display ON, charger connected Pin 1: 4.74V Pin 3 and 4: 0.00V Pin 5: 4.64V Case 4: display OFF, charger connected Pin 1: 5.11V Pin 3 and 4: 0.00V Pin 5: 4.74V Any help is greatly appreciated. Best Regards, Nawaz

About a year ago, I came across this LED lamp that was on sale at my local Target store. It caught my eye because it had a little tray at the base of the lamp along with a USB port for charging my devices. Since the first time I plugged it in and turned it on, it makes a buzzing noise. At first it didn't bother me, but now that I am spending more time at my workbench it has become annoying. I understand it is kind of common for LED bulbs to do this because of the dimmer switch being outdated, however this lamp is not dimmable nor is it a "bulb" so to say. It's about 7-9 SMD LEDs on a circuit with a rocker switch. If it makes a difference, I do have my lamp plugged into a surge protector and don't have anything plugged into the USB port located at the base of the lamp. What can be done (other than throwing it away, of course) to stop the buzzing noise coming from the lamp? Thanks in advance!

Hi there, Firstly, I am a mechanical engineering student with a limited knowledge of circuits and electronics, so therefore I may be a little out of my depth. However I am very keen to learn about electronic circuits and have completed other simpler projects and that is why I am attempting this project. So onto my dilemma, I want to use my universities Shield of Arms to make a car badge for the single-seater racecar we are building as a project. However this badge won't just be a run-of-the-mill plastic car badge. I want it to be made from stainless steel (laser cut) and acrylic with the idea that I will solder a bunch of LEDs in series and when the ignition is turned on, the LEDs light up one at time until they are all lit, after which they all flash three times together and then remain lit up until the ignition is turned off. The LEDs I intend on using are 0603 SMD LEDs and the aim of this whole design is that it is reasonably thin (No more than 1/4 " or 6.35mm thick for the PCB however ideally I would like it to be as thin as is physically possible. The dimensions of the badge will be very similar to a Porsche badge (51mm by 69mm). I have included the Shield of Arms in question and also the Porsche emblem for comparison. Also price is an issue since as I am a student, I have limited resources, so if someone could point me to some cheap electronics parts shops etc it would be greatly appreciated. (I live in the United Kingdom so a lot of American shops will be unavailable to me) I don't really know how to read schematics but I do have friends working on this project who do, however if anyone can guide me in the right direction with maybe a couple of how-to's (particularly the requirements for the lighting up process) and some really good pointers, it will be very much appreciated. If I have not made myself clear I do apologise and I will be happy to explain further should you need to. Thank you all in advance. I hope to hear from you soon. H

Boy do I have a deal for you! I've been working on an uber-clock project recently (it's going to be really really awesome!), and it entails a very interesting display -- a 5x16 array of SMD LEDs.I tried making a homemade PCB, but it was impossible to use, so I'm sending my order out to a fabhouse for some real ones. While I'm at it, I'm offering you, instructablonians, the chance of a lifetime: Owning one of these awesome* boards!For $18, you get the PCB and 100 red SMD LED's! (LEDs courtesy of T3hMuffinator) -- this price pretty much covers the cost of the board & shipping.For an extra 5 bucks, I'll stuff the board with the LEDs for you.(The 5 bucks is to cover the solder paste, and the labor involved :P)It definantly needsto be stuffed with solder paste, the parts are very close together. It is litterally just the LED matrix, there are spots for it to be connected to a controller board, where the resistors would lay.EDIT: Heres the schematic, sch file, and the board.EDIT2: New board design, much much more compact! 3.15" x 1.20"! EDIT3: Just in case we get a flood of replies, I'll repeat 'Muff.He's supplying the LEDs. They're avaliable in red, white, yellow, and 1 other color. They're from [www.select-technology Select Technology] (eBay UMO88)EDIT4: I also have controller boards availible. They're basically an AtMega8, resistors, header pins, power, etc all on a board the same size as the array. (not an easy task!) They're $18, PM me fore more detailsI also have some POV boards availible. They are uber-compact, at only 0.8"x0.6"! They come with 10 SMD LEDs. They cost $5 a piece. Just add the Attiny13 & power!For $15, you get the POV PCB, the LEDs, 11 Male & 5 Female header pins, a DB-25 connector, an Attiny13, and its socket. Its everything you need to use this PCB. (Note: you need a parallel port on the back of your computer in order to use this board to program the uC)Its a very self-explaintory PCB, which makes it great. Its compact size is great for a few different thingsAn instructable is coming really soon on making/stuffing/using it, so don't dispair!---All three boards distributed by Rethinker Industries and liscenced under by-nc-sa.

I am just getting into SMD work for PCB's & I was curious when I am using the electric skillet method for solder reflow does the PCB have to sit on the skillet itself or can it slowly pass over & the heat that is coming up from the skillet still cause the solder to flow like it would sitting on top.

Hey everyone, Recently I purchased an smd LED just for learning purposes. Personally, I have no clue how to use it and where I can put it. I have read on the internet about how you can use them for reading lights, buses, planes, etc etc. They are extremely small, and only 2 very small places where I can solder wires to. I have no clue how to use this. Do you use it on a circuit board? Not using a circuit board? I have no clue. Thanks a ton, Brennn10

From kick starter page: Create circuit boards in minutes, from home, at the cost of a cup of coffee - Squink prints conductive ink and assembles your circuit. Atmel had posted about a new device called "Squink". What it does is print a circuit board on paper (or anything flat like glass), applies conductive glue to the contacts, and automatically places your components on the board for you! They have a kick starter here: https://www.kickstarter.com/projects/botfactory/squink-the-personal-electronic-circuit-factory but I am 13 and cannot fund it. I believe this device will be found in the home of makers all over, and I think spreading the word will help these people. So please head to the page and fund/share the word!

I want to an LED Strip that works my USB or Battery, I got the battery and the USB working fine, the battery charges up without problems, but I need to light the LED Strip (12V) with a 5V battery. Is there a DIY way to: -Step up the voltage, or -Step down the LED Strip Voltage. I know each SMD LED works around 3V, but I can't make sense of the wiring and resistors on the Strip, to wire the SMDs in parallel.

OK, here's what I'm thinking. I wanna lite the bottom edge of a piece of plexiglass so it will lite the edge all the way around bright green. I have enough of the super small SMD LEDs. I wanna be able to do them a in single row using 30 or so of them end to end. Is this possible, if so how would I get the right voltage for this? And would I need to use resistors?

While I was taking apart some disposable cameras, I found this "strange looking" camera's circuit, it looks like a old type of camera's circuit, it is probably used in the first disposable cameras. They are no SMD components, a large capacitance capacitor (160uF), three transistors, and a funny looking trigger transformer on the circuit. Have any of you ever found this kind of camera's circuit?

Hi, I am working with a Flyron FN-M16 MP3 player module which has both output for headphones (pins 4,5, and GND = 7), and a 3-watt amplifier for speakers (pins 6 & 8). The problem I am having is that I am unsure of how to disconnect power to the speakers when headphones are plugged into the jack. This is easy when you have a separate amplifier circuit, but here the amplifier is built in. The easiest solution would be to find an audio jack with an isolated NC (normally closed switch) to disconnect the speakers. They do not seem to make them in SMD packages. I have found a 3.5mm stereo audio jack with an isolated NO (normally open) switch from Technik.HK. Is there a mosfet type circuit that I can use to disconnect the speakers when the NO switch is closed without introducing any distortion to the speaker sound? Any advice for an electronic disconnect? P.S: The manufacturer has stated that if I ground the speaker outputs for the 3-watt speakers I will blow out the internal amplifier on the flyron Mp3 player board.

I have a bunch of LEDs (mainly 0603 and 5050 smd, 3mm, and 5mm - all colors). Most of them don't list a reverse voltage. Those that do say 5volts. My question is, do any LEDs have less than 5v reverse voltage? Is it possible to accidentally kill them by connecting backwards to a 5v power supply? Should I put resistors on both the positive and negative to protect them (would that even work)? Thanks.

Hi there I have an idea in mind and would like to know if you guys think it would be possible to make. The object is for the battery to last a minimum of 150 hours of constant use. I want to use the smallest possible LED say 2mm or even a SMD will be sufficient, the led must run off a very small battery either a LR44 / CR1225 or something similar in size and the design must have an on off switch. Do you have any suggestions? Is this even possible? Any ides? Thanks Matt

This is my first post so please excuse if I am in the wrong place :( I have a boot bracelet with a leather back and ornate bling glued to the leather and sewn at the edges. I want to add small LED strip lights, weather proof, cutable every 3 lights, double-sided adhesive to the center (between leather and ornate mesh side. I want to be able to turn it on and off. I figure 6 mini strip lights should be more than enough. Here are the lights I have: Features: Superbright 3528 SMD LEDs with high intensity and reliability. 5 Metre strip with 600 LEDs Self-adhesive back with double side adhesive tape. Maintenance free, easy installation Long life of 50,000 hours Flexible strip which can easily be curved around bends. UUltra-bright but running at low temperature Viewing Angle : 120° Input volts: DC 12V This Cool White strip light has 600pcs Double Density,SMD 3528 LEDs The Strip is Customizable for any length you want, Cuttable every 3 LED's without damaging the rest strips, flexible and can be bent at any angle, Works with a 12 Volt Power supply Low power consumption, Eco Friendly, High Quality, high intensity and reliability, High Quality Cool White, Double Density 600 LED's, 3528 SMD 5M/16.4 ft, high intensity and reliability, Long lifespan, Hopefully that helps. What I need is a battery source that can be added to the inside of the bracelet that will light it up and allow me to turn off and on (push on/off is better than switch). The source would have to be in something waterproof like a latex substance and can only take up a minimal amount of space 1.5 - 2". Obviously the batteries would have to lay flat (flat coin-like batteries?) Is there ANYONE out there who can give me ideas? Thank you!!!

Hi folks, I hope this topic is in the right place. I was going to try my hand at building my own LED light bar like the one in the picture below. It will be around 40" long with 2 rows LEDs and running off a 12v car battery. What W LEDs would you recommend? Also materials, what would you use for the housing, clear front etc? I was looking at 10w SMD Chips but I'm not sure if they are super bright but then again there are going to be a lot of them in the bar. They have a operating Voltage of 9-12v, if I have so many of them will i need some sort of amplifier half way down the rows? Any help with this project would be greatly appreciated, Thanks in advance. Chris.

Inspired by the Illuminato Arduino clone (can't really say clone because it's so much better!) really wants me to create my own Arduino clone. I've been thinking of making a clone for the Arduino Mega, but it'd need so feature that the original Arduino can't offer (like the boarduino is breadboard compatible, Sanguino has way more pins, Illuminato is the most beautiful PCB I've ever seen and has a lot of I/O's). So, I'm asking you guys! What features would you want in an arduino? If this "new" arduino is so much better than any other existing one I'll make kits (if the majority is through hole) for people to buy (no more than 40 dollars, probably, the 65 dollar price tag is a real turn off for the Mega) or just assembled if the majority is smd. Also instructable :P

I recently made an amplifier based on a TDA2004 chip i salvaged from a car radio but i wanted to get more power and so i planned on making a 20w or more version. Problem is, i don't know what chip to use. Can you guys help me? Criteria: 20w or more (just give me the max wattage the chip can carry) non-SMD chip, preferably on those chips that are on a multiwatt-like package min voltage lower than 6v (around 5v or less) and higher than 6v (obviously) load the chip can carry must be 4-8 ohms About the wattage, just give me the max wattage. I've been running the tda2004 for some time now on 6v only and it's pretty loud, just not loud enough on open areas (rave party, anyone?) Anyways, just tell me the power amps you know of that'll satisfy the criteria or at least close to it. I need answers in 4 days or so, so please tell me ASAP. Thanks in advance!

Hi all, I want to illuminate my laptop keyboard and since the name of the device is LAPTOP meaning it is a mobile device, the tutorials on Youtube were not that promising ... and trust me I searched a lot. I work at a lighting company, we have tons of led stips ... the lowest is a 12V 7W LED strip and that's 7W per meter ... the closest CUT-HERE mark on the strip involves 6 SMD LEDs which is enough for me, this strip doesn't overheat, I put my finger on it. The question is it possible to solder these 6 LEDS to the 12V DC power jack of the laptop or the USB power (+ / -) port ( on the mainboard ) .... as for the strip itself, I can install it on the Laptop Chassis, not necessary inside te Chassis in a very neat way. can it be done? is there any risk on the laptop ? .... will the USB still be usable ? ( again I don't want to plug a USB cable to power the LEDs I want to solder on the USB port on mainboard) Thank you

Hi all, I'd appreciate some feedback on my UV screen project. As a relatively new blog I have effectively zero traffic there, so I thought I'd ask for some feedback here. The goal of the project is to provide an easy way of converting a record player to a UV screen (as pictured). The idea is to replicate the appearance "Death calls the tune" project by Lab Binaer, although I'm avoiding using an arduino in an attempt to keep costs down. The ultimate goal is an instructable, but before that stage I hope to work a bit more on the available functionality (currently it will just write text to the screen, each phrase being written alternately in one of three positions). Here are some planned but as-yet unimplemented short term goals; Investigate replacing the serial connection with V-USB New modes (Bar graph output , Seismograph style output, Spiral text) New stylus using SMD LEDs (currently uses 5mil) Offload all settings to XML file Slow rotor speed further I'd be appreciative if you could offer ideas for new functionality, uses, modifications, any thoughts or comments. Thanks, Drew

I think, for this, i would maybe be best off building the suit from strips of waterproof 5050 SMDs like this: http://www.alibaba.com/product-gs/615439688/business_agent_smd_505_led_strip.html Power would be in the form of the biggest 12V power supply I can find. The only problem here is that at full brightness, the suit is going to consume A LOT of juice... I have seen this costume which is similar in construction, except all the LEDs twinkle (like TV static): www.youtube.com%2Fwatch%3Fv%3DLal9uma1iVc&ei;=nwgtUNT7B6_Z0QXekYGwDA&usg;=AFQjCNENmYUCu_AwYaEAwqAiWSDFRFnUeg&sig2;=FXRYO81ccZavpYyeBsZMyQ This has the added advantage of lower power draw as not all of the LEDs will be on at the same time. I actually much prefer this concept, however I have absolutely no idea where to begin on schematics... Any insights or friendly advice from the experts would be handy, I have a rudimentary knowledge of electronics, and am very handy with soldering. Thanks!

Here's a weird one for you guys. I recently bought a Beer tap handle and noticed that it had an insert that had some LEDs on it. Cool. The problem is that the LEDs don't light (beyond a tiny SMD red LED heartbeat). I found a small button that when depressed seems to trigger a test. Bright white LEDs on the top and bottom flash to illumnnate the top of the tap (either a clear baseball or FIFA tap topper) as well as the body. It's hollow plastic so it briefly glows. The problem is that I can't figure out how to light the things beyond the test (for which you have to remove it from the handle). The guy who sold it to me said they've sold lots like this and could never figure it out. I figured light sensor? nope. Tilt sensor so it'll flash when you pour a beer. Nope. I broke out my loupe and noticed a funky thing on the circuit board that looked like it had an antenna. It was an Anaren A1101R09A. This thing is a radio tranceiver! That tells me there was a remote with it that was lost in the few days after they bar got their new tap handle. Does that sound right? If so I was wondering where I could get or build another. I could put together some other LED solution, but I'd love to get this to work. HEre's a pic of the tap handle and the insert laying on it's side. The right side is the up side with the transceiver. It's blue if you look closely. Not sure I'll get a solution, but there's some clever people here, so you never know. Thanks for reading.

Is reverse engineering illegal? Well, if you then go on to sell your version? For example, in an upcoming instructable I'm modding some electronics, well, without revealing my instructable here's an equivilent example: Lets say I buy a little robot at the store, it has motors and the case and everything. Only problem is, it runs on AA's and you want rechargable batteries. Also, the wireless module for some reason is external and is super ugly and annoying. You crack open everything and you find that the needlessly large circuitboards only have about 20 (somewhat) easy to find components that adds up to like 2 dollars. Following traces, you recreate a schematic from the PCB (already did this, that was fuuunnn :P). Now you reengineer the board (still same schematic) so that it's much more compact, you've added a little charging circuit (and correspond boost circuit, replacing a couple of AA's with a lithium ion), and you made it all fit inside the robot (no wireless module just hanging around outside the robot. Now, essentially the schematic is the same, but you've added stuff like the boost circuit and charging circuit. You've also added a few customizing features that make it more special (adding LEDs, microcontroller, cough cough etc.). Would it be illegal to sell a board/kit (incase other people want the board and can't solder smd to good) for people to modify there own robot (same model etc.). Also, the schematic from the reverse engineering is very similar to an example circuit in the main chip's datasheet, and a few other parts are common sense (like some resistors here and there, LEDs, a few extra filtering caps), so the company's circuit is nearly identical to the datasheet, is this illegal to sell?

I've been eying the VS1000, a little bitty chip that is basically an all-in-one Ogg Vorbis player, just add a crystal & memory. Its so beutiful, so tiny yet so complex... it even has a great default firmware. I've finnally got around to making this. I'm sending the PCB off to be made, and getting parts to prototype. Stats? Size: 2.19"x1.48", roughly twice the size of a new shuffle, or half the size of a new nano. I haven't figured out depth, but it uses li-on batteries, so it will not have a lump on the back, it should be comparably thin.Capacity: uses microSD cardsConnections: 3.5mm stereo headphone jack, microSD card, and miniUSB. Via miniUSB, you can charge the battery, as well as read/write to the SD card.Audio Support: Only Ogg Vorbis, but then again, it is the best codec, you can convert everything to it ;-) Max bit rate: 500 (beat that Apple!)No screen :-(Cost:This is tricky. For me, if I didn't buy any spare parts, its going to cost me $100. If I had an SD card, it'd only be $80. If I semi-mass produce them (more than 20), I know I can cut at least $10 off that price.So, it pretty much beats the Daisy, our, the OS/DIY community's, current audio device all around. Except one thing... it isn't a beginners project, involving nearly all SMD components, the only exception being the headphone jack. And the main chip is a bit of a pain to solder -- 12 pins on each 1 cm side ;-)Still, I think this is promising... along with my micro-POV... in making things smaller, like the "real" devices :P

I will be opening an electronic kit store (and specialized cnc work, depending on what you want) and I'm just getting stuff prepared, such as PCB templates, etc. If you would like to see somthing in my store please suggest it now, everything will be very cheap, here are some of the things I'm working along with estimate price (I'll have a fixed one later, this is just what it'll be around). THESE WILL ALL BE KITS, LIST WILL BE UPDATED TO SHOW DIFFERENT PROGRESSES Custom PCB - 1 dollar initial, 50 cents per square inch Various breadboard mini power supplies - 1 to 2 dollars, somewhere around there 5 VOLT POWER SUPPLY DESIGN IS DONE WORKING ON VARIABLE, 3.3, 12 Dream Machine - Induces Lucid Dreaming by flashing LEDs through your eyelid throughout the night to help you realize your dreaming without waking up. $3 1/2 DONE CR2032 batteries - like 50 cents a piece, some of my uController kits use these DONE Joule Thief - Some people have trouble with this, so here's a kit ~1 dollar Dip Converter - like 50 cents, solder on SMD IC's so that you can use it with DIP sockets and/or breadboards Pulse LED Musik - I did have an instructable on this, but I think it should be properly done, no definite price yet. MAYBE THINGS Mini Cnc machine, mill your own small (like 4"x4") board at home! 60-100 dollars Fm transmitter for MP3 players More universal TV-B-Gone clone kit (better for mods) Magnetic levitator, that's a big maybe Homebrew Ipod accesories Universal uController Programmer little bread board volt meter little breadboard amp meter BB jumper wire and templates for jumper wire So, any suggestions? CONSIDERED INSTRUCTIONS BY INSTRUCTBLONIANS... UHHH PEOPLE From Tech-King Cables and Cords and plugs Custom plexiglass etching/engraving Project Boxes (I might buy from a big supplier at a discount and pass on the savings! Or eventually make them) Soldering kit HAM products
