Infrared transmitter and receiver

I want to make a gadget which sends a few kb of data via infrared and also receives data via infrared with a timestamp. However, I am stuck as I have only used arduinos before and I have to design a circuitboard which I have never done before, with PIC microcontrollers (must be cheap ones). I need help a) choosing a microcontroller and b) assembling all the components into a circuitboard (ir transmitter, receiver, microusb port to transfer data to pc, battery). Gadget will eventually be portable so make everything light. Thanks Khalid

Can you piggyback RF communications on cellular transmit/receive frequency bands ?

My question is purely hypothetical and there is no immediate plans for any such application. But I was just curious is it possible to make use of the cellular frequency bands (as set out by a country's regulations and by the cellular providers) for some sort of covert type communication other than for voice, data or text types of cellular communications ? Would it be too difficult and complex to develop such an application that uses cellular radio frequencies or could it be done without too much concern for potential interference or the sharing of channels of nearby normal cellular transmissions ? Could such an application be developed without having to cross over many hurdles ? If this covert communications is possible would the cell frequencies used not reach the base stations of the wireless carriers as noise or can a peer to peer communications be possible by passing the base stations ?

The Information Revolution -- Perhaps we're too connected?

Being a target victim of a hacker, I suddenly came up with an emergency protocol (Emergency Protocol 06) which involves computer scans, network disconnection, pass code implementation, security questions etc. Now several hours afterwards, I started to think about the dangers of the information highway, as perhaps we're speeding a bit too fast, end up in a high-speed crash and all that. Then after that, I asked myself, "What if this highway were to blow up?". That being the crashing / destruction of all or at least most of the servers in the world. All of the information, connections, gone. Sure, the satellites serve as a sort of backup cable, but really, it's not enough for the world to use. Hell, the only reason the Philippines has any internet is one, tiny, undersea cable from Japan. Not exactly tiny, but it's the reason why our "fast speeds" are just painstakingly slow to the more developed countries. This is more of a survival question, after a post... post... I don't know. Won't be really post-apocalyptic, but it is suckish and all communications gets cut around the world. If it were to happen, what will you do? Oh yeah, don't post stuff like "that's impossible" or improbability whatnot. It's a theoretical situation that is highly unlikely to happen, but if it were to be...

Annual Instructables Community Review

Hello, everyone, I would like to share with you my experience in this community for about 7 years of being a member here. Instructables members are very talented and very reliable also they are supportive. The community helps me to grow as an enthusiast in technology. This community is very educational. I really recommended this community for any makers around the world. I love being a member here and show what I made. I believe sharing is caring, so if we share each other's idea our world will be better for the next generations. I am lucky of being part of Instructables Community since 2009! (Wareneutron) P.S. Review this community by leaving a simple reply to this post! I hope everyone will share their thoughts and opinions or even feedback about this growing community of makers.

Class assignment on the MAKE/Instructables community

I need the Instructables/MAKE community help with a class project. "To develop a persuasive argument in response to this question: "Are virtual communities, real communities?"" I decided to pick Instructables community, being that it is mostly online, making it a plausible virtual community. This community is also very open minded and sophisticated, and have no doubt that I will get plenty of input and good arguments. I hope can accomplish this and not sidetracked by all of the cool stuff the is always on the front page. So let the posting begin! Funny note, someone in my group picked myspace under the same prompt, that is going to be funny ass to see how that pans out.

Community Project Website

Hello All,  Recently, I came across this website for people to collaborate and create things for the community. I thought this would be a good place to share it. Many of us make things that benefit community, and we all have different backgrounds. This is a free website that we can post projects on, and can get crowdfunding. It seems legitimate, and is for sure worth a try. A friend of mine started the idea behind this website, if any of you guys have any ideas to work on in the community, you guys should give it a shot.    The website is: www.innovatebuild.org -rlingineni

Community sections not displaying accurate info

I noticed that several community sections and topic lists are not displaying correct data. I don't want to sound like I'm nit-picking (because I really do like this site), so I hope staff takes this as an effort to improve things and not just as criticism. :) The following sections display incorrect data: (https://www.instructables.com/community) Community > Forums > Newsletter Archive (shows last post= 1 year ago, but last post was yesterday). Community > Help > Contests (shows 0) Community > Marketplace > Jobs & Internships (shows last post= 6 months ago, but last post was 4 days ago) The following sections do not display topics in the correct order based on most recent; Community > Marketplace > For Sale, Free Stuff, Jobs & Internships, Services and Wanted (only "Kits" is displaying correctly). Community > Help > Bugs and FAQ's Finally, if I may make a suggestion... I have noticed that when a new topic is posted, it does not show up as the "last post" as indicated on the root "community" page. Instead the "last post" is always based on comments. Too often, I think members are missing new topics because they are unaware that they exist if they are basing the activity of a section on the "last post". I think its worth considering that a change be made to reflect the "last post" by activity instead of by comment alone. Thank you for your efforts to make this community a great place to be. As I said, I hope my comments are taken as constructive and not just as criticism.

Just stopping in...

Hey everyone! I haven't really been active here on instructables for a while (I still do check it daily though!). I have been using a bunch of other forums lately (AndroidCentral, XDA Developers, etc...) and I have to say that instructables, BY FAR, still has always been the best forum experience for me. The community, the forum layout, the community, the "Public Profile" page, the community, and, oh, did I mention how awesome the community here was? I would like to commend everyone here for making instructables one of the best websites around. Great job! -Kcls

Survey on the Workflow and Collaboration of Makers and Their Community

Im currently conducting research for my final year thesis which the aim is to identify insights gathered from this survey to understand the workflow and collaboration of the online and local maker communityMy aim at the end of this is to identify what could be beneficial for the maker community, whether it be in the form of a physical or online tool or even a set of guidelines to act as stepping stones during conceptualisation and prototyping for a user. You can answer the survey herehttps://goo.gl/forms/f2zjFwxyefxrKRpO2 This will be great help to get some participants and I hope my research and resources gathered will be a benefit to the online and local maker community.

Arduino UART communication quandary

I'm trying to hook up a 5v Arduino to a 3.3v datalogger. I just realized that in all the time I have been messing around with micro controllers, I have never communicated serially to a device that wasn't 5V. I was about to just wire the two devices together when I thought better of it and figured I should look into the matter a little further. Can I just directly connect the RX pin on the 3.3V device to the TX pin on the Arduino? Or do I need to add a resistor in-between? Or a voltage divider? Actually, that wasn't all that many questions. Basically, I'm just wondering what is good form in communicating between devices of varying voltages?

Instructables.com in the Classroom

Hello All, I have been in the Instructables community for the past 9 months on a personal account.  I currently teach computer technology to grades 5 and 6.  I had a thought that this community could be a great resource for my students to look for information and also share. My question to the community is this.  Is there a designated area of the site or community that is solely education based or are there groups of teachers that share how they use this site and contents in the classroom?  More specifically computer tech type classes. Hoping to hear back from some fellow educators. Regards, MyDemonsTech

Community Project Idea

I had an idea that once a month, I (or anyone else) could post a list of materials. Then the community (you) could come up with ideas using some or all of the matierials. The person(s) who posted the original list of materials would pick the best or most reasonable project/idea, make it, and put up an instructable on it. Let me know whether it would be something anyone would like to do.

Implementation of two way communication

Hi, I'm working on a project where we're working on a tele-operated robot and we are looking to include the ability to have a conversation. We would be looking to use earbuds and a microphone on the operator side and a speaker and microphone on the robot side. Does anyone know how to go about implementing this? It needs to be hands free on both ends as the operators arms are being mapped to the robots arms. Thank you.

Questionnaire - Help Needed please

**First of sorry if this is not the correct forum to post this in** **Bit of background, I'm Fergal from Ireland, 22, and currently studying Communications in Creative Multimedia and have a request if any of you would kindly help me** I'm doing a Virtual Ethnography assignment for a module on my course titled' User Theories' and thought Instructables would be a great online community to research as I've had the enjoyment of using it a few times for college projects. Side bar: A Virtual Ethnography is the study of people interacting in an online community. I want to look at why people give up their free time and spend a lot of time and effort to help others with tutorials. I want to also explore hierarchy within the community and see if there is any influential or highly regarded people within the community. Also just general observation of the Instructables community. So if you have time i would appreciate it immensely if you could fill in the short questionnaire below. Would really help me out a lot thanks. Look forward to hearing back from you all. Thanks!! 1 – What is your age, gender, location? 2 - How often do you visit the forum / post on the forum? 3 - How often do you browse Instructables? 4 - Do you feel the Instructables forum offers a sense of community? How does it differ to a offline Instructables community if any? 5 - Do you find it easier to communicate and voice your opinions online on the forum, than offline face to face? 6 - Does being part of the Instructables forum make you feel a sense of importance ? 7 – Have you ever met anyone from Instructables offline face to face ? [If so elaborate please, how? when? Still talk?] 8 - Do you think there's a downside to communicating online rather than just offline? 9 – What do you think is the best aspect of communicating in the Instructables forum? 10 – Do you communicate with any Instructables members on facebook/twitter or any other messenger? If so how many, how often, in depth conversations or small talk? 11 – How many projects have you made successfully from Instructables 12 – Have you ever subsequently made money from following a instructable and selling on what you made? [examples please/ elaborate] If any questions dont apply to you, please even just try answer as any feedback / knowledge about the online community will help me greatly!! If you think of anything else that is not mentioned and that would help me, i would also be grateful for this info. Thanks again, Fergal McCabe @Fergal_McCabe D00125983[at]student[dot]dkit[dot]ie​

Is the KNEX gun community dead?

So there has not been a post in the KNEX forum section for weeks about KNEX guns and It is getting so slow and dead around here that I could not stand it any more so I thought I would post a topic to see what others think. Are any of you working on stuff? I know some KNEX gunners have moved to YouTube but there is still very little content also a lot of people have left I know years ago everybody was saying that the community was dead but there was a nice jump in activity in the last year or so but It seams that stuff is dead as meat around here know. I found this community to be are very welcoming and fun place on the internet and I would hate to see it dead for good. Is there anybody that has plans of posting again? I just want to know how things are going has everybody lost interest or just grown out of this hobby? I hope that we can come back to life but I don't know will 2015 go down as the year the KNEX gun community died? Hope all is well with all you KNEXers!

soft serial communication on Arduino Micro.

Hello all, I have a few Arduino Micro units, and need to connect them together (in a mesh network) so that every unit in it is interchangeable, meaning that any unit may be in connection with more than one unit. As the Master/Slave form is out of question at this stage (because any given unit cannot be both Master and Slave at the same time, of course) I decided to go for a simple serial communication. However the Arduino Micro units (and frankly none of the Arduinos) do not have sufficient serial pins and I was advised to use Soft Serial instead. I was looking into the pin out of the Arduino Micro but cannot quite figure out which pins I can use for the serial comm.; I need 4 to 6 serial communications. Any help is much appreciated, as the nature of the problem may not be changed. So I need to solve it as it is. Karim.

WANTED: Simple Appliance Timers for a good cause: Our community garden

Hello community! My communal community farm here in Chicago sends all its produce to a local food bank. Yay! So this year, to boost output, we're looking to help equip our volunteers with seedling starter setups, which include a crazy full-spectrum lamp and, notably, a timer to control the lamp. We'll be buying the lamps, but would anybody in the Instructables community be interested in building us some timers? No dynamic programmability needed, just has to stay on for the same hours every day this spring. I would suggest one of the projects already featured on this site, but none of them seems to be capable of the long hours that the present application demands. (Or maybe one does?) Something mimicking the functionality of this device would be ideal: http://www.amazon.com/Woods-50006-Indoor-24-Hour-Mechanical/dp/B006LYHED0/ref=sr_1_6?ie=UTF8&qid;=1361900546&sr;=8-6&keywords;=timer+outlet Please let me know if you're interested.

Starting a community to trade your old cables, electronic components or computer parts

Dear all, We are a small company located in Singapore and we are starting a community for the trading and reselling of your old and unwanted cables, electronic components or computer parts that are lying around your house. So help us do our part for mother earth by visiting the following link:-  http://sites.google.com/site/ventincrecables/green-ventincre As a start and due to the lack of funding, we will temporary use google group to host all advertisement postings. Hopefully, as we move along, more funding will start flowing in to enable us to utilize a better platform like tal.ki so that more people would be able to take part in this small project that we have. We will be really grateful if you can join this community by posting your advertisements and also, donating funds from time to time as these are crucial for the survival of this community. Our future plans would be to include the donation of computers and laptops to communities in developing countries, charities or schools. Do feel free to drop us an email at needitbadly@gmail.com should you have any queries or suggestions. Yours Sincerely, Ventincre!
