This method requires another computing device as well. The only issue I see with this great for remote access but not the best to use as a screen in many situations. Other possibilities if you have a VGA based TV get an HDMI to VGA with audio converter and stick your RPI to the back of your TV viola a cheap PC for every TV in your home. I would like to see RPI alternatives devices that run on faster storage medium would be great like a hard drive or SSD for instance. Even better yet would be USB SSD drive boot or possibly next gen SD card storage will provide improvements to be more comparable with hard disk drives at the very least.I love the possible but for me it lacks a lot storage being its largest bottleneck. Maybe this will change in the future I sure hope so.Other possible things do exist out there for RPI already they do make usb based displays. They also make HDMI to DVI adapters methodology of using VNC is cool on a tablet but it would be neat to see tablets come with micro HDMI inputs and allow switching of inputs as a standardization in the future as well as phones. It would be a very cheap addition that would add a lot of possibilities to smart devices. It would also stop phones and tablets from hitting the landfill as quickly as well.
There are plenty of people who still use it personally I would bet that many people have pi's sitting around collecting dust we could say the pi is used for this or that or the other thing the great thing is you can use it for whatever you deem worth using it for. I have a pi personally that is collecting dust with all of the IOT stuff available. I did however look into using it as an AMAZON echo speaker the only thing I do not like about echo and alexa is how they have made the process a lot more complex than it needs to be to carry out a custom command. Making the addition of personalized commands does not suit the consumer if done so in a fashion that IS NOT consumer friendly it is geared towards you having to sign on for AWS as a consumer and jump through a bunch of hoops to hope you can interface it with great difficulty with your personal needs. This product is geared towards developers at companies not towards consumers and what they would like to use it for there are folks who are out there making it work with the pi though. There are many other things to try with the PI for me but with all of the devices currently available I have been focused on other things more cheaper devices that are a bit more centered in specific areas of IOT. So many things to do and learn for a single person it makes your mind spin and the time in a day the time off aka free time seems to get eaten up at a rather quick clip.OK so it is so 2012 might I ask what do you do with your PI? Bitcoin miner managment was so 2014 so I am curious what you have brewing seeing as how things you say are aged and dated etc... BTW I currently enjoy the chrome cast version 2 for media as well as roku and messed with the firestick a little as well but really the PI did do a good job for media to be rather honest. Some people have even written guides to replace their cars CD play with a touchscreen and a pi heck I read that in 2015 though. Many things to do so what is it that you do?
Why something is designed and how it is used is two different things. Many people use the PI believe it or not for all types of things. From facial recognition to open their door to a cheap computing platform that is accessible to anyone to a media center based OS running on it capable of playing HD Video there are many ways to use the PI imho but I know a lot of people likely have or can easily get ahold of old VGA monitors etc in this case for next to nothing and turn them into an All In One Linux PC to serve whatever needs they wish. You can also hook up cheap small touch screens using GPIO if you want the possibilities are not limited to the designers intention. We all have different intentions for using the PI I am aware of the history of the pi have followed it since its inception actually but just because intentions exist does not me that people should adhere to a specific set of intentions. For me improvements are always a possibility and your own creativity is your limitation I recall some folks running windows in a VM just because it was possible on the first iteration of the pi now was it any good no it was a dud a snail etc hardware limitations made it so but as dies shrink and processing gets cheaper more will be possible. I realize things are the way they are currently but far from set in stone the pi has become a staple to computing culture and has been used and hacked to do all sorts of neat things above and beyond its original intent. Would you have it any other way? I know I would not!
Sure this is really a side issue the brunt of my point was to offer solutions to using an external monitor although I would be there is still a way to interface tablet monitors somehow. The users title is very misleading so I was attempting to help take off some of the pressures of this but exercising discussion about monitor use. As I said I am well aware of usb drive based use scenarios but it almost would have been better if that was where the image was ran from or heck even a sata port would have been a cool addition ... m.2 anyone?I covered reasoning in depth to add other storage options ports etc.. mainly speed based issues. Again all of it is not relevant I suppose to the OP but the misleading title was sure to generate discussion and maybe that was the OP's intention now that I think of it.
It is a method I picked up from somewhere when reading about methane digestion and the possibility that we produce more than enough waste to store and heat our homes via a methane digestion. That got me really looking into things and methods being used. The same thing goes for anything you can pressurize gas via this method to some pretty high pressures it is fairly safe to do if you know what you are doing I would assume obviously you won't want to be smoking lighting a cigarette next to it or store it by the toaster at the edge of the kitchen counter. But I am sure there are more safety precautions to follow in order to know them one must know how safe storage is done, know their storage medium is safe, know that all the correct valves and pressures are used etc
What you or anyone else does with this information is not my choice and in reading any of this you agree to consult a professional and accept all liability and responsibility for applying anything I am NOT an expert nor do I know any of this is correct. Any direction here may result in misdirection so be safe and consult a professional on this type of thingI have an idea that may just work: Simply scale this up use a pool of sea water a large tub of water mount your anode and cathode on the syringe instead in a manner that will retain high pressure. Also mount a one way valve to the top. You will need to have high pressure tanks with regulators that will be monitored 100% of the time as hydrogen is dangerous and explosive. From the hydrogen side what you do is add weight to the top of the syringe (which will likely be a bucket or something else in your case. To get 30lbs of pressure add 30lbs to the top of the bucket. When the bucket floats up they hydrogen is under 30lbs of pressure.

Any direction here may result in misdirection so be safe and consult a professional on this type of thingThis is a method for pressurizing the gas that anyone can do at home. It is important that all safety is followed to a T. I suggest you look up all safety issues in hydrogen storage as many have died or been severely injured trying to do what you are going to attempt. While it is possible to do safe it will be appropriate to know what is safe and what is not also what is legal and what is not. Different valves will be required and tanks composed of specific materials will be required also valve checks must be preformed annually by a professional to ensure the safety of your operation as these valves much like your tire valves must be replaced quite often the tanks should also be inspected.What you or anyone else does with this information is not my choice and in reading any of this you agree to consult a professional and accept all liability and responsibility for applying anything I am NOT an expert nor do I know any of this is correct. Any direction here may result in misdirection so be safe and consult a professional on this type of thing Essentially what you have is a bomb just waiting for any one wrong condition out of many conditions to release its energy and explode. This is not a guide to safety or me telling you exactly how to do this this is simply knowledge of getting to where you want to be. I highly suggest having a professional assist you with your setup. Safe distances, pressures, equipment, temperatures, and monitoring 100% of the time weather automated or not are all a part of the equation for hydrogen storage it is important you do not cut corners on any safety.What you or anyone else does with this information is not my choice and in reading any of this you agree to consult a professional and accept all liability and responsibility for applying anything I am NOT an expert nor do I know any of this is correct.

First off you have some fairly awesome tutorials sous-vide is pretty interesting a pretty trendy subject for the last couple of years have yet to try it as I prefer my steaks in the non perfect fashion well done and seared on the outside to me they are easier to chew and I prefer the flavor and texture but to each their own. I also read your laser printer tutorial a while back still need to come across a cheap laser printer and settle on the method as well as learn how to use board design software I hear you can use a magic marker to cover the areas and draw traces etc just as well dunno have not tried.Anyhow this one kind of was a bummer as I read it through until the end and figured out that I wasted a ton of time do to an incorrect title. This is not "programmable" at all as I am looking at doing things in a programmable fashion.programmable would mean that it has programmable settings what you have here is not that it is simply a digital thermostat it is important to distinguish the difference! Programmable thermostats have all followed the same standard up until the NEST type devices which are smart or learnable. This standard as programmable was a weekly timer that was included what is important to me is to learn how to setup several daily timers 48 of them to be precise to be user configurable and operate on a weekly schedule. So what is missing from this project is huge the entire "programmable portion" carrying the weekly timer lol! What you have is a digital thermostat more or less from what I can tell after skimming through the code looking for timer code. DOH!Anyways you should come join us we could use some good instructables over this way http://www.esp8266.com/viewforum.php?f=38Aside from that I think you'd like and enjoy playing with the nodemcu if you have not already there is a wealth of possibility in this one little cheap device if nothing else.
I have done this before ran into an issue though the light I got was massively bright and hot melted the case and the color wheel never really messed with the type of light I purchased before but hoooo man you want to talk about blinding light this thing was insane. On a side note a typical 100wat bulb is 1600 lumens ... But I think the fella that had the idea from the car light hit it right on the money... Anyhow your post is fairly old and LED has come a long way since then so I am sure you have found the way... Easy way to find the circuit to trick is look for two optocouplers actually often you can just trace these out and just cut and splice wire that is there to make it work.Anyhow I enjoyed your posting a bit nostalgic for me ;)
