Arduino and scavenged LCDs

Hey guys i've recently received an Arduino Uno (tech-mas gifts !) and have started trying stuff out, i also had 2 old cellphones that i hadn't used for years, so i scavenged the vibrators and screens and left the rest untouched(no ripping appart, worry not) now i see that the screens both have a plastic thing with a lot if very tiny pins sticking out of them, and i wonder if there would be any way i can connect these to the arduino and use them as displays (was thinking of a smart-not-phone, wich does all the funny stuff a smartphone does without the phonecalls), please keep in mind i have a very basic set of tools (the arduino, a breadboard and the "starter pack"(with leds resistors ect...), plus a soldering iron, and would like to keep this project salvage based if possible (no money for smart-not-phones) info i could find on the displays: 1st one is a LMS240GF12,(non touchscreen) i couldnt find any info on this model but a few similar displays with lms241 or 242 names exist, so i guess the specs should be similar ? 2nd one is the touchscreen that came with a HTC Wildfire phone, and i think the display serial would be A3333 G8 but i'm not sure, none of the information is labelled and internet has been of little help as of now ^^. If you have any tips or need more info i'll be glad to receive them

Will scavenged parts survive soldering?

If I pull components out of, say, a dead radio, will those components survive the heat of resoldering? Considering they've already been soldered once, and the leads clipped short, are they still REALLY viable?

Need ideas of object to scavenge

Hello everyone, i'm working to build some home made toy, but I am missing one important piece. To find it at minimum price, I need to find an every day object that would contain a shaft with a driving ring. The ring would also need to be able to move along the shaft. Can anyone help me to find some idea ? where can I find it? I'm sure it must exists in plenty of objects, I just can't think of any.... thanks ! :)

Scavenging Smartphone Touchscreens for DIY Projects

Hi All, I'm trying to figure out how feasible it would be to harvest a touchscreen from an old smart phone (say, a $35 LG on ebay) and integrate it into a DIY electronics project (eg. an Arduino project). Are the connections just hopelessly convoluted inside the phone or do many phones have fairly sensible screens that can be re-used? Thanks in advance for any insight. Sean

How can I identify the values of recycled mylar and ceramic capcitors using the codes on the side? Answered

I have desoldered a couple of old radios etc. and am trying to identify all the components I have harvested. Amongst them I have some green mylar caps. One such cap has the markings: 2A473J I did a bit of research and found out that usually the first two numbers is the significant figures and the third is the number of zeros. Assuming its not counting the 2A, I'm guessing this cap is 47000pF or .047μF. and I found out that the J is +/-5% tolerance? Firstly, is everything I have worked out/ assumed true and if so and the cap is .047μF, what does the 2A mean? Others say 2A73J, 2A103J, 2A332J, 2A222J, 2A102J Ceramic ones say 4, 22, 30, 33, 102, 103, 104, 203, 221, 222, 331, 332, 333, 473, 682, 683 And I also have 4 of another type of cap that I don't know the name of- they are shown in the 3rd picture. the two smaller ones say 474 on, one say 8.0M and the other:16.93M Thanks in advance

Photo Scavenger Hunt: Your Mom Edition

Hello everyone!  I've got some patches that are burning a hole in my pocket, and I'd love to share them with you! Here is my plan:  on a not at all regular schedule, I will come up with a harebrained idea for a strange and/or difficult to acquire picture.  I will take an example picture and post it in the community blog.  You will then go and take your own version of said picture and post it here in the comments, and in return I will send you a patch.  Sound good?  This needs to be your original picture, but if you feel the need to cover your face or whatever, that's fine.  Just make sure that you identify yourself in some way, say with a sign or something with your username on it.  For example, if I cared about preserving my anonymity I would wear a paper bag over my head with eye holes cut out and "Depot Devoid" written on it in sharpie. Photoshop is fine to touch up pictures, but don't overdo it.  I don't want any pictures that are completely photoshopped fabrications . . . unless they are really awesome.  I reserve the right to be the sole judge of what is awesome and my decisions are totally arbitrary and cannot be appealed to a higher authority.  I AM THE HIGHER AUTHORITY MWA HA HA HA!!!! Anyway, here's your first Photo Scavenger Hunt objective:  A picture of you and your mom (or grandma, or some reasonable facsimile thereof), engaged in lightsaber combat . . . to the death! Go forth my minions, and bring me pictures!

How can I identify the power rating (wattage) of my scavenged resistors? Answered

I am currently making a mini guitar amplifier, from this instructable, https://www.instructables.com/id/Make-a-Sweet-Portable-Guitar-Amp/, and i need a 1kΩ resistor. I have accumulated a few components by de-soldering and scavenging parts from old, and broken electronic devices. When I found out i needed a 1kΩ resistor, I looked up the ring code for that value and scanned over my broken electronic circuit boards to see if i could find a match. Which i did, but i do not know how many watts the resistor is rated at. The resistor in question is no more than 3mm in length. I know that quite a lot of resistors are more like 5mm in length. Can you tell from the physical size what the resistor I have is?(I will include a couple of pictures)

Where can i find (scavenge) a 555 timer and other commonly used ICs? Answered

I have a special interest in components retrieval from out or no-more-in-use eletronics, and since i live out ou the US that is probably the easiest/cheapest/quickest way to get some parts. A mini-question: what is the main application of the 555? I've seen it mostly controlling dc motors and blinking lights and in some amps. Knowing the use of it is another way to know where to find it. So, just like a stepper motor can be found in most (if not all) printers and scanners, where can we find ICs and other crucial parts for projects?

Cyber War with a Shovel?

A 75 year old woman has cut Armenia off from the internet. Whilst scavenging for copper in neighbouring Georgia, Hayastan Shakarian accidentally severed the fibre-optic cable connecting all three of Armenia's internet wholesale providers, and the whole country was cut off for almost 12 hours until after midnight on the night of 28th March. The pensioner has been arrested, and could face three years in prison, but has been released pending the completion of the investigation and the result of the prosecution. Armenian websites identified Shakarian as Armenian herself, not Georgian, and questioned the credibility of an old lady causing the blackout, claiming similar damage in Georgia has caused problems for Armenia in the past.

Help with my brainstorm

Hi everyone, I have an idea for a new gizmo that I'm trying to make a working model of. It will use a 12volt electric motor and want to spend as little as possible on it until I'm pretty sure it will work, so I'm going to scavenge for parts when I can. The most expensive parts that will go into it is the electric motor and the battery and I have a few questions: 1- Does an electric motor draw whatever power it needs or is the power forced into it? 2- If it draws what it needs, can I take a 12volt motor and use an 18v battery with it without problems? So if I scavenge an electric motor from a 12v battery powered drill can I run it with an 18v lithium battery? 3- What about the amps? If I use a 12v motor that normally runs off a 12v car battery, can I run it with an 18v lithium battery that has less amps? 4- Any other specs I need to focus on? 5- When I find the right electric motor, which I think will be a small 12v gearmotor, where should I go to find a low cost supplier? I'll have more questions later but if you could help me with this I can get started. Thank you! Bretina

bicycle dynamo to power AC outlet?

Good stuff.Ravens can toboggan, ride other animals and spy on their enemies. Their life as cadgers stealing prey from wolves, eagles and bears has made them outstandingly intelligent.

How can I Scavenge/Salvage a crystal+audio transformer from an old radio (or anything!) for an AM transmitter project? Answered

Hi! My name's Bashu, I'm 18. My electronics skills are pretty feeble but I think I'm trying to get a better idea about how they work.. by making projects! old homeschooler reflex. So my brother has an old 1982 lovable Toyota Tercel named Humphrey. Humphrey was passed on to my brother the way God or Toyota made him.. with an AM radio. This is pretty rad if we want to hear Chinese/Spanish/Italian radio jockeys (they have really nice vocal rhythms), except usually we don't for some reason. So I wanted to make an AM transmitter. I found a project on here. https://www.instructables.com/id/Make-a-simple-AM-transmitter/ Looks pretty simple. Requires an approx 1 mhz crystal and an 8-1000 ohm audio transformer, which I was prepared to buy, except then I heard about salvaging them from cheep radios! VERY EXCITED WAS I! I love reusing old things that were once very incredible (taking songs out of the air? Magic) and would otherwise go to the dump. Alors, I bought an old clock-radio from a thrift-store, opened it up and looked inside, and realised I had no freakin' idea what the crystal or audio transformer would look like. I then decided to enlist the help of the only community I thought would know. You! My question is, if I wanted to find a 1 Mhz Crystal and a 8 into 1000 ohm audio transformer, without buying them, where would I be likely to be able to salvage them, and what will they look like? Pictures of the radio I bought and opened up are attached, in case they are on there and easily spottable. I don't mind digging. Thank you very much for any advice you have! I am also thinking it would be really cool to have an instructable dedicated to salvaging components from various equipment. I found a wiki on it, but it's somewhat incomplete and has no photos whatsoever.
