I've been looking around here for some time and it seems like there are not many series that cover everthing about how to design and then develop a website. I thought it would be awsome to create a instructsble serie that let's someone develop there own website in pure HTML & CSS. So I have a couple of ideas. - explaining the basics of flat design (todays standard in web design) - creating a website in pure html & css from the ground up - creating a compleet wordpress theme - much more If you like one of the above ideas or if you have one of your own, please let me know.

Design and development in the New World

From the MAKE blog, I found an outstanding article in The Economist on product development in the age of rapid prototyping. In their usual fashion, The Economist gets into the nuts and bolts of how a pair of entrepreneurs used rapid prototyping and Kickstarter to create a real product from their initial ideas. It's a great case study for DIY-ers who think they have something marketable, to show how they could make that happen.

Simple Software Development for Drones

Hello Hackers!  I’m David and I’m the head of Developers Relations at NVdrones. I’m writing to you guys and gals because I think you will be interested to know about what we created. We create a platform that allows any hacker to write an app for a drone in the most simple way possible. Meaning you can create a pace of software that will control a drone autonomously based only on inputs from sensor that you attach to our board. No need to know C, change firmware nor spend thousands of dollars for a flight controller that allows swapping of the firmware. With our solution you can by the cheapest flight controller for around 30USD, attach our board (NVextender) and have a solution that can be programmed using Arduino right now and Android, Javascript and more in the future. We just pre launched the developer website http://developers.NVdrones.com and would like to invite your audience to take a look. If you would like to get the pre release Developer Kit send me an email at developers@NVdrones.com and let know how would you plan to use our platform. Best.

Need a Game Development Team

Hey all, I'm looking to put together a small dev team for an indie game project that I'm planning. I'm working from the ground up here, so just about every role is still open. Experience is a plus, but I really only ask that you know what you're doing. The project will be a 3D Sci-fi/Fantasy RPG with a unique style of combat that combines the strategic skill-based systems of JRPG with the real-time fluidity of Western games. I'll put the project on a crowdfunding site like Kickstarter after I have a team and the completed GDD, so some stretch goals might include expanding to MMO or VR. I can give more specific details if you have questions. Roles to Fill: Programmer (C++, Unity 3D) Artist Level Designer Composer Scripter/Writer Voices (maybe) I couldn't pay immediately, but payment would probably be a fixed amount or a percent of the crowdfunding. If anyone is interested or has any questions, let me know.

help wanted developing cool fidget jewelry

I have had an idea for creating cool non childish fidget toys as jewelry. My real idea is to create something which could use an ir sensor to pick up someones pulse and then play it back to them through a vibration motor.. (its similar to baby's reacting to there mothers heart beats in the womb an has a massively calming effect on most people,,, to the point where build a bare workshops has the option to include a beating heart)   I submitted the idea to Quirky but it wasn't taken on for one of there projects.. I think it still has legs an could be a commercial success. being there's already a bit of interest from educators who has seen research pointing to fiddle toys as being the best thing since the carbon atom arranged itself into cool new shapes. There are a few other alternatives which could be developed.. an i think it would be awesome to develop a whole range of these things an see them in jewelry shops looking like ailion artifacts with documents about how they can help you..  I think everything about it should be play with able , so magnets textures ect ect  Here is the initial idea  ____________________________________________________ People fidget,, A lot of people fidget. A lot of the time.. They fidget during presentations, on commutes, whilst thinking of ideas and whilst being productive on the internet. And that’s not a bad thing. Fidgeting helps people to be who they are. They wouldn’t do it if there wasn’t a good reason for it. From what I understand different parts of the brain are responsible for different things. And some of them are associated with each other. Interestingly for most people learning is enhanced when there doing something. Much more of the brain becomes active when any movement is involved. Retention of information becomes greater and creativity is increased as the parts of the brain associated with these things become active. I did some independent research on the strength of the book (Fidget to focus) when I did my teacher training, And found that though I didn't have a class full of what some would deem the unteachable I did have a class full of tappers, twiddles and shakers. When I gave them all the option to utilise just a simple shaped piece of wood, and the permit ion to fiddle with it during session they loved it. The feedback I got from the use of the wooden shapes was terrific. With 8 of the 15 students “forgetting” to give the shapes back at the end of the session. And the class being more engaged during the session. The Solution I aim to develop a range of warble fiddle toys primarily as jewellery. Jewellery is now gender neutral, A fiddle toy worn around the neck would allow for an easy accessibility in comparison to being fixed to an item of clothing. Jewellery can allow for a range of shapes to suet different people and allow for a shape or shapes ideal for those wanting to play. So far I have made a shape and seen that people like to play with it. I think the minimum next step would be to make this shape in different materials to give different textures weights and looks. But what I would really love to do would be to introduce all sorts of awesome new functions into the fiddle toy jewellery. I would love to include a number of different haptic responses potentially echoing the users pulse. This has been shown to calm infants simulating a factor present in the womb I know the sound of a heart beat is known to relax most people and has been included into calming music I suspect the same as a tactile would be just as calming helping someone to come from an elevated heart rate to a calmer one in a sympathetic match. Or starting off strong and diminishing from its trigger. Iterations could include a variable trigger like an old school stress relief toy. Magnets with a ruggedized coating to avoid clicking, tracking a whole host of things which could be useful in giving the user the best tools for understanding when they fiddle and why. __________________________ For the Quirky proposal which is pretty much exactly what is above https://www.quirky.com/invent/1603684/action/vote/query/view=trending&categories;=all

3D Printer Enters A New Stage Of Development

  As a new type of manufacturing process that using rapid prototyping technology,3D printers aroused widespread concern when it was published. A new product was initial pushed into the market, people concerns its functionality and price more than its shape and so on. 3D printer is no exception. Initially, people's attention focused on its cost and performance.   What way reflected cost and performance for 3D printers? I believe that there are three main areas, including printing speed, printing volume and resolution. For consumers, what level achieve these three areas and which brand is more competitive? Next, I will be based on my own experience for everyone to make a resolution.   As a Chinese brand that created independently, LXMaker won the favor of consumers from different countries by its excellent performance when it was pushed into market and sales was rising gradually. Recently, LXMaker launched a new all-metal 3D printer that was named Iron Man series.Three aspects of the machine has been greatly improved.   First is the super high printing speed:Take advantages of the cross shaft structure innovation and the unique design to separate feeding device  with extruder at both sides, instead of Makerbot's heavy printing head (loaded with 3 electric motors, illustrated as below). LXMaker's light & handy extruder guarantees high speed printing. Imagine, if you are running, unloaded or  carrying bags, which is faster? The maximum nozzle moving speed of LXMaker can reach 500 mm / sec .     The novel cross shaft structure introduced above has win the big prize of "The Best Open Source Hardware"and"The Most Precised and Fastest 3D Printer",nominated by the world-wide well-known Make Magzine.   Second is the super large printing volume:The maximum printing volume is up to 260x260x400mm, outstanding of 3D printers at the same price.    Finally is the super high resolution:LXMaker has a very precise Z axis movement, which ensures the precision in practical. The theoratical precison of Z axis is 0.01mm, while the actual test precision is only 0.02 mm, which guarantees the super high quality of the workpiece, and can effectively prevent deformation in the printing process. Ths precision of X & Y axis can also be as high as 0.125mm.   In addition to excellent performance,the price of the Iron Man is very close to the people.The machine of maximum print size that need 2199 dollars was located in moderate level in similar products, so that consumers that come from all countries were able to withstand it. Because of this,LXMaker owned today's sales.   As time goes by, the point that people focus on the 3D printer was also not limited to the cost and performance, but rather more attention appearance and stability of the machine. Because considering this change,LXMaker introduced Iron Man series.   Iron Man series used all-metal structure and the whole machine has a very high stability.In addition,it was very strong.And it didn’t produce crack or fracture because of a slight collision. So it has better adaptability for long-distance transport, consumers do not have to worry about damage of product because of long bumpy.   At appearance of the machine, Iron Man series launched black red and blue creatively.According to their preferences,consumers can customize the 3d printer that belong to themselves.And three colors of the machine is filled with the fashion sense and the modern sense.This feature meet the requirements of the product appearance that digital technology enthusiasts. The method of LXMaker is designed to meet the trend of customization.   New products always went through a process that from performance to shape after published. Eventually,the overall level of products will be improved by leaps and bounds. 3D printer reflects the development process of this law fully. Therefore, the most critical for the business is to discover consumer’s mindset changes and adjustments based on the changes in a time.It is the only way that owned good yields and returns. The only constant is change.

RF Development Kit-Advanced, but could be a lot of fun

Micrel SemiconductorEbay{{{ I have noticed that some people are concerned that due to surface mount technology you can't make electronic stuff anymore. It is not true. A search will quickly find forums discussing how homebuilt electronics experimenters are getting around this. I have a nifty RF development kit for sale on ebay. See ebay link below. These development kits are used by new product developers to quickly get their RF prototypes up and running to develop software, hardware and firmware without the steep learning curve associated with starting development with discrete components. These boards allow you to build custom devices that can comunicate with each other up to a mile apart. Although this is not quite ham worthy distance someone might be able to have some fun with the kit. I have just one, but more (and the actual rf chip) could be acquired through Micrel Semiconductors. Anyway, I have this listed as an industrial item, so I am not sure the right people will see the ad. For those interested in playing with current technology RF.}}}

Simple, yet annoying mistake made by game developers

I have found a simple yet annoying mistake that game developers seem to love to make. Before I go on, lets get this straight: Parkour is a method of movement focused on moving around obstacles with speed and efficiency. Originally developed in France, the main purpose of the discipline is to teach participants how to move through their environment by vaulting, rolling, running, climbing and jumping Free running or freerunning is a form of urban acrobatics in which participants, known as free runners, use the city and rural landscape to perform movements through its structures. It incorporates efficient movements from parkour, and adds aesthetic vaults and other acrobatics, such as tricking and street stunts, creating an athletic and aesthetically pleasing way of moving Okay, so the main difference is that free running is pretty much parkour, except it involves flipping, tricking, and is just all around more free; hence FREE running.  But here's the thing I made this forum topic about. In the  Assassin's Creed series, you climb up buildings, jump from one to another, and that's pretty much it. Scaling, jumping, rolling, and that's all there is to it. Yet they call it free running. You don't flip or trick or anything, therefore isn't it parkour and not free running? Another game where this mistake is made is in Tony Hawk's American Wasteland--but there's one difference. In THAW, you do front flips, back flips, wall flips, you climb buildings, scale buildings, etc. So it should be called free running, right? Well tell that to the guys over at  Neversoft, because they call it parkour. Why? What is it about these developers that make them blindly call something one thing, when it's actually another? Do they even think of looking at sources? Have YOU seen this mistake in OTHER video games? Tell me your opinions on this!

Very Small Scale Power Generation in Developing World

Hello Everyone, I volunteer for a non-profit which distributes solar lanterns primarily to students as well as people who are in need of the lights.  Things have been going well but a lot of people have inquired about us providing access to a higher powered version for various reasons and we've noticed that some households go back to their old ways when the lanterns don't receive enough sun during the day.  Temporarily we are solving the problem by having local entrepreneurs charge batteries for the families for a small fee but we feel that this should not be a permanent solution. It's not the price that's the issue it's that sometimes the people have to walk for a number of kilometers to get to the nearest charging station or have to cross dangerous terrain (I have personally experienced this). Over the last 3 years we have helped over 5000 families by giving them solar lights so we would like to modify all those units to have more stable energy generation. Our current version has an output of 5 watts. We are looking to buy or build a unit which produces a maximum 8wh an hour until the fuel source runs out or something that can generate in a more slower rate such as 40wh in 16 hours so we can let it run overnight and have the power stored in a battery. We are primarily a donation driven group so something with low cost and maintenance would be really great.  We highly subsidize the price to a large percentage of the households but we also provide them free for the lowest 10% of households who can't even afford the lowered price. I personally think that something which can generate electricity from hydrocarbons due to their high energy density and easy access would be ideal but I'm not an engineer so what do I know.  I'm not sure if this helps in any way but a number of years ago we transitioned a large number of houses from wood fired stoves to gas and as all the families that we help actually have access to gas I was wondering if any good technology exists where electricity can be generated by gas that can meet the low cost and maintenance criteria.  I've looked into thermoelectric generators but they are really inefficient and people will be wasting money to heat their house in a country where average temperatures are in the 30'sC I also see a future issue regarding battery degradation as we use small lead acid batteries and while thinking of a way to solve this I came up with the following idea and is one of the reasons that I'm posting on instructables. What if a pedal powered flywheel generator was built with a 200W generating capacity and 40Wh worth of 'storage'.  When you pedal you will spin up the flywheel and it will store the energy until you need the electricity again and we could also wire up the solar panel that we already use to spin up the flywheel.  So when the sun is out the panel is used and on rainy days and during the night you pedal for a couple of minutes for one hour of lights.  If the flywheel can store the energy for a number of hours then someone could pedal for a couple of minutes at a time throughout the day and not have to do it at night. This is just an idea that I came up with and if anyone has any ideas I'll be really interested in knowing about it (obviously the above solution is not ideal because they have to put some work into generation but it's the best that I can do).  I've quite recently been looking into different types of fuel cells powered by m/ethanol and others like solid oxide cells and they seem interesting (does anyone here have any experience in building these type of cells?).  This community has a lot of intelligent members who think outside the box so I'm confident that we can come up with something. This ended up being a bit longer than expected and if you've read this far, thank you. I wasn't sure about what section to post this in, square peg is the one I chose out of 5 so if this is wrong please feel free to move it to the correct section. Help and advice will be very much appreciated. Kindest Regards
