It's also my only finished project so far: an alarm clock
Made for ~2 days, because I couldn't get up on time.
Currently flashes light into your eyes and buzzes with a piezo crystal and has wifi15
!rant I guess. Its coffee on a chip. Just spend 3h making this board to be implemented in my coffee machine. Just to wake up with the smell of coffee. The board is 2.9 by 3.2 cm12
1. Fucking MySQL database clusters.
There's nothing fun about MySQL clusters. Sometimes they start producing deadlock errors for no apparent reason... well, there's probably a reason, but it's never a transparent easy to find reason.
What was even less fun is that those errors took down a Sentry server. When your error log server goes down through ddos from your database messages, it's time to rethink your setup.
2. Wiring up a large factory with $2 arduino clones, each with a $2 esp8266 wifi chip, with various sensors for measuring flow of chemical solutions (I wanted cheap real time monitoring as an early warning system next to periodic sampling).
The scaling issue was getting over 500 streaming wifi signals to work in a 55c moist slightly corrosive atmosphere with concrete and steel everywhere, and getting it all into a single InfluxDB instance for analysis.12
I've spent three days trying to upload some code to my ESP8266 and it failed every time. Now I just plugged the Arduino at my Desktop and it works. Notebook USB port does not provide enough current I think.17
Just went to the pet asylum to look for a cat. There was a shy black one (eh, maybe not a good first but Moar Blacker, Moar Better 😋) and a black and white one which was very open towards me.
Probably I'll get the latter, and build some food, water and litter dispenser systems for it with motors and my esp8266 boards 🙂
The lady who was volunteering there and showed me around had an interesting story though.
Apparently both of those aforementioned cats were wild cats (so they don't come from a proper household or anything). Except that black and white one which apparently came from some rather retarded people.. think average Facebook user.
According to her those previous owners came there with 2 cats including the black and white one as "extremely wild, we found them in the forest, put them in cages (because everyone carries cat cages in their car every day, right?) and brought them here". Nice excuse for average Facebook user level of retard I have to say 😜 but it's not very waterproof, you know?
But on average the people that they get there are even worse than that.. some get a great initial meeting with a cat, but then leave them there because they don't like the stripes on a paw or something stupid like that. As she put it: "you're not fitting pants in a clothing shop, are you?! 😑"
Had to try hard to not burst out in laughter from that description 😂
Point is, the average customers there are awful.. apparently she was very grateful to have a rather down-to-earth customer like me and my home supervisor (who helpfully drove me there 🙂) for once. So terrible clients.. they're everywhere!
It really taught me to be mindful of the hardships of people in any profession who deal with clients.18
Arduino + Bluetooth + L293D + car Chacis and 4 DC motors.
Finaly finished my second bot/Drone.
Actually finished it yesterday but had lots of problems with hardware bugs (learned so fucking much in a day).
Tought I fucked two unos with bad soldering... No they are fine, just won't turn on in the circuit that was already working (was fine running the code).
Redone everything from scratch with a arduino uno, it's perfect now.
Funniest part is how I got my hands on a 50€ car kit for almost free... So some Chinese store sended this kit instead of some cheap stuff. Saved another arduino with the chip rack (that one that you can trade the atmega chip), I'll save it to program single chips. Plus a h bridge and lot lot more cool stuff.
Used only the Chacis.
Next: esp8266 and camera... And maby a gun? Would be cool32
Hey folks, this is ben.
Just a little story of me and IOT
,for the past few months, i have been working on various projects on Internet of Things and, with the little exposure... I have seen so much goodies that come along, i love the robust and realtime architecture that IOT has, on my platform i use
Arduino, esp8266 and Android, i am able to control my car park, home lights, and my pulse rate using the few components.
At first it was hustle, but now? Am loving it😋😋😋,
If you wish to join me or have a project of the sort..... Just holla me up :email@example.com
I can also teach for free.13
So I made this simple lamp that shows what is current build status on Jenkins CI.
- Change color depending on Jenkins build status
- Automaticaly turn on/off if user is logged on Hipchat
- Beam effect if somebody makes coffee
- Unicorn effect if food is delivered
- Big red arcade button that can send random message to somebody on Hipchat
A few days ago someone posted a pic of an ESP8266 microcontroller, so it reminded me that I have one of those lying around with a board with a screen I built during summer, so I thought, why not making a devrant reader, and so here it is:
For now it can only read rants, posting is coming soon, the software keyboard is already implemented
We call it the thing (Accrocchio in italian)5
So proud of being chosen as the fourth of the best 5 best Ambassadors of the IEEEMADC contest world wide representing my country Kenya,a contest that am so proud of IEEE and for the people who worked day and night to make it a success.
So proud to know other great people world wide such as Ambassadors from other countries .Big up Farooq Hassan for giving us good directions and most above all Eng. Hezbon orina for giving the spirit to always move on. 🎊2
Evaluating some WiFi ESP8266 modules. 01, 12S, 14. Programming is very simple with Arduino IDE and esp8266 community.
This iot world really excite me.
ESP-01 about 1$, oled display about 2.5$...
Project is to create my own HomeKit modules. (Relay switch, temps, garage door, etc..)10
This is not really the reason I got these parts, but I just had them lying around and have been following the project for some time... so why not? Haha. I was also thinking it might be cool to set these up to auto-disrupt known AP names that would be issued by companies most responsible for the dismantling of Net Neutrality. Like just make them in a dirt cheap throwie form-factor and let the companies deal with pissed off customers for a few days until the battery dies (thinking the little generic LiPo’s that cheap quadcopters use would give a few days if attacking sporadically and using the ESP’s sleep function). Just riffing here... ;P ;D2
@Condor did you mention this?
One of my final projects... To connect gas, movement, IR pir and do a all arround protection sistem. I'll build the on-off for the gas difectly in the box for the arduino, it's the easy way, since I can now make an app to control it online.
Sorry forgot the pic20
During one of our visits at Konza City, Machakos county in Kenya, my team and I encountered a big problem accessing to viable water. Most times we enquired for water, we were handed a bottle of bought water. This for a day or few days would be affordable for some, but for a lifetime of a middle income person, it will be way too much expensive. Of ten people we encountered 8 complained of a proper mechanism to access to viable water. This to us was a very demanding problem, that needed to be sorted out immediately. Majority of the people were unable to conduct income generating activities such as farming because of the nature of the kind of water and its scarcity as well.
Such a scenario demands for an immediate way to solve this problem. Various ways have been put into practice to ensure sustainability of water conservation and management. However most of them have been futile on the aspect of sustainability. As part of our research we also considered to check out of the formal mechanisms put in place to ensure proper acquisition of water, and one of them we saw was tree planting, which was not sustainable at all, also some few piped water was being transported very long distances from the destinations, this however did not solve the immediate needs of the people.We found out that the area has a large body mass of salty water which was not viable for them to conduct any constructive activity. This was hint enough to help us find a way to curb this demanding challenge. Presence of salty water was the first step of our solution.
We came up with an IOT based system to help curb this problem. Our system entails purification of the salty water through electrolysis, the device is places at an area where the body mass of water is located, it drills for a suitable depth and allow the salty water to flow into it. Various sets of tanks and valves are situated next to it, these tanks acts as to contain the salty water temporarily. A high power source is then connected to each tank, this enable the separation of Chlorine ions from Hydrogen Ions by electrolysis through electrolysis, salt is then separated and allowed to flow from the lower chamber of the tanks, allowing clean water to from to the preceding tanks, the preceding tanks contains various chemicals to remove any remaining impurities. The whole entire process is managed by the action of sensors. Water alkalinity, turbidity and ph are monitored and relayed onto a mobile phone, this then follows a predictive analysis of the data history stored then makes up a decision to increase flow of water in the valves or to decrease its flow. This being a hot prone area, we opted to maximize harnessing of power through solar power, this power availability is almost perfect to provide us with at least 440V constant supply to facilitate faster electrolysis of the salty water.
Being a drought prone area, it was key that the outlet water should be cold and comfortable for consumers to use, so we also coupled our output chamber with cooling tanks, these tanks are managed via our mobile application, the information relayed from it in terms of temperature and humidity are sent to it. This information is key in helping us produce water at optimum states, enabling us to fully manage supply and input of the water from the water bodies.
By the use of natural language processing, we are able to automatically control flow and feeing of the valves to and fro using Voice, one could say “The output water is too hot”, and the system would respond by increasing the speed of the fans and making the tanks provide very cold water. Additional to this system, we have prepared short video tutorials and documents enlighting people on how to conserve water and maintain the optimum state of the green economy.
IBM/OPEN SOURCE TECHNOLOGIES
For a start, we have implemented our project using esp8266 microcontrollers, sensors, transducers and low payload containers to demonstrate our project. Previously we have used Google’s firebase cloud platform to ensure realtimeness of data to-and-fro relay to the mobile. This has proven workable for most cases, whether on a small scale or large scale, however we meet challenges such as change in the fingerprint keys that renders our device not workable, we intend to overcome this problem by moving to IBM bluemix platform.
We use C++ Programming language for our microcontrollers and sensor communication, in some cases we use Python programming language to process neuro-networks for our microcontrollers.
Any feedback conserning this project please?8
I think I may have shared this a while back. Just played with this a little for fun. I was playing with an ESP8266. Apparently it takes very little code to turn it into an access point and have it redirect to a landing page just like a hotel wifi does. Every platform I had connect to the AP seemed to work properly. I setup the AP without a password and let people log in. I named the AP "Virus Distribution Point". Here is what they would see:
Don't mind the name of the repo. It is a junk repo I made for making mom jokes.7
FUCK YEAH! FUCKING HELL FUCK YEAH! IT FUCKING WORKED! THE FUCKING CODE FINALLY COMPILED PROPERLY!
I was trying to use the Adafruit Feather HUZZA esp8266 with the AdafruitHTTPClient Library... and it didnt work... then I downgraded THE FUCKING FIRMWARE FROM 2.5.0 TO 2.4.2 AND THE BLOODY THING COMPILED!3
Now everyone were sharing their worksetup I thought I would want too to.
So here it is.
I have two laptops (one belongs to startup I work at) I use same keyboard mouse for both using synergy.
I have my editor and node server in one laptop and I check them out on other laptop (both are medium range laptop hence they are not exactly powerful). I am running Linux mint in both.
Then I have some embedded stuff on desk which is my hobby(currently working on esp8266 dev board that I built).
You can also see a projector clock I built projecting current time on left beside my bigger laptop. (Projection is on wall beside it)1
Operating system for esp8266 based mcus, think Android (OS, APIs, App store) for mcus. Currently writing the docs for the OS APIs. If sounds interesting, check out https://prismos.dev1
I Did NOT realise how fucking great I2C and an esp8266 can be, simply connect up a few sensors like BME 280 and a few others, implement the Adafruit IO capabillity, done. Fucking Amazing!
Show me how you made an http server with an arduino nano and an esp8266 via AT commands from the arduino, the arduino handling the clients.
No you didn't, this shit is fucking impossible.4
Any NodeMCU owners, using ESPlorer, here? I am thinking about rebuilding it completely with a better UI/UX and adding a C++ language support.
What do you think about it? Any suggestions or features you want?
If you are very interested in this project:
I am trying my hand on blogging
Any pointers or feedback is appreciated. :D
Recently received my ESP8266 and for bad or for worse quickly flashed it to use thingsSDK and espruino.
I have setup a webserver on it but at the moment you need to go to its local ip to see the page, does any one have tryed this before and overcome to redirect all requests to that page? Any ideas are welcome, i know this can be done easly with LUA but cant code LUA, yet...13
So on saturday I download vscode, I also installed the PlatformIO IDE so I can do esp8266 development. At this point I thought I had everything I needed. Later that day I was in a place where there is no internet. I started up vscode and went to create a new project using PlatformIO in vscode. It started having internet connection issues.
I am not used to my IDE interfaces needing network just to operate. Really dissappointing.
Does VSCode require internet to operate?2
