DONE. ENJOY.
Arduino Libraries Required:
Adafruit_Sensor.h
Adafruit_BME280.h Go to Tools -> Manage Libraries : search for bme280 and select the adafruit one, and install all.
Wire connections:
- 5V and GND to coresponding
- the marked ones SDA, SCL on the end of the digital pins
- or the analog pins A4 (SDA) A5 (SCL)
Wire connections:
- 5V and GND to corresponding
- the marked ones SDA, SCL on the end of the digital pins
- or the analog pins A4 (SDA) A5 (SCL)
Arduino Code:
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27,20,4); // set the LCD address to 0x27
void setup()
{
lcd.init(); // initialize the lcd
lcd.backlight();
lcd.clear();
lcd.setCursor (0,3); // first parameter its the line 0,1,2,3 - second character position 0-20
lcd.print("Hello World");
}
void loop() {
}
If you have more devices on the I2C buss you can change the address by soldering the A0, A1 OR A2 connection on the PCF8574T board.
To display a special character : lcd.print((char)228);
Contract and Backlight
- In case you don't see nothing on the screen, use a screwdriver and adjust the blue potentiometer on the back.
- The backlight on/off is controlled by the jumper
- jumper in place: backlight on
- jumper removed: backlight off
The backlight can also be controlled with software.
Use lcd.backlight(); to turn it on and lcd.noBacklight(); to turn it off.

By bus :
Flixbus – check their Route Map – its super cool for finding connections between cities
Let me give you my itinerary i did : I left Paris at 22 and arrived in Munich at 10 – visited Munich until 18 and took a bus to Prague where I arrived at 23 and when to a hostel – as Prague its 2-3 times cheaper compared to Munich). I stayed two nights in Prague then did another drive through Vienna and went to Budapest where again I stayed a few nights ( even cheaper rent for a hostel bed ).
By train :
Check InterRail – package train travel around Europe
Verifica costul transportului de la aeroporturile mici pana in oras. Zborurile lowcost aterizeaza departe de oras si costul/disntanta pot sa nu merite. http://www.terravision.eu - low cost airport trasfers
Check Uber prices as well, especially if you have a night flight in some places its cheaper then taxi in others is more expensive.
I got in Paris a shared Uber for 6.5 euro and public transport would have costed me 4 euros but it was more hassle and I was tired so the Uber was well worth the extra 2.5 euros.
Taxi: foloseste o aplicatie sau comanda din aeroport. Intreaba pretul altfel.
Tip: ask for a free metro/transport network at your hotel/hostel, don't spend 10 euro on one.

Bitcoin: Is a cash system where the ledger with transactions is hold by a Peer-to-Peer public network, where anybody can check transactions.
In order to validate transactions miners have to do some work - solve some mathematical problems, and hence use some power and resources. The more people participating the more difficult the mathematical problems and the higher the security, as it requires huge amounts of processing power.
It becomes unprofitable for one individual to spend that much money on the hardware and power need it to run it vs the value gained.
Miners assemble all new transactions appearing into large bundles called blocks, which collectively constitute an authoritative record of all transactions ever made, the blockchain.
In order to make sure there is only one blockchain blocks are really hard to produce.
So instead of just being able to make blocks at will, miners have to produce a cryptographic hash of the block that meets certain criteria, and the only way to find one is to try computing many of them until you get lucky and find one that works. This process is referred to as hashing. The miner that successfully creates a block is rewarded with some freshly created bitcoins.
Every few days, the difficulty of the criteria for the hash is adjusted based on how frequently blocks are appearing, so more competition between miners equals more work needed to find a block. This network difficulty, so called because it is the same for all miners, can be quantified by a number.
Mining pools: by sharing their processing power, miners can find blocks much faster. Pool users earn shares by submitting valid proofs of work, and are then rewarded according to the amount of work they contributed to solving a block.
A documentary released in 2014 The Rise and Rise of Bitcoin
How is the bitcoin fee calculated ?
The value of the fee its not related to value of transferred bitcoins but by the size of the transaction in bytes.
This is calculated by the number of in transaction for the wallet multiplied by something like 180 plus the number of out transactions for the wallet multiplied by something like 34. So getting bitcoins paid adds more to the fee then paying with bitcoins.
Then the bytes values of the transaction get multiplied by a value called satoshisthat its network dependent : how many transactions are happening and what fees people use.
Most apps have some default values where they will use a value so that you transaction will get into the next n-th block based on some settings you input or uses some default values.
You can check satoshisvalue here : https://bitcoinfees.21.co/
How much profit can you make mining ?
(Your power / network hash power)* Coins generated per day * Coin price
Say you have 1 THash miner 1.03.2018 for Bitcoin:
(1/23.500.000)*1800*11.000 $ =~ 0.85$ / day
Minimum bitcoin transation is : 5460 satoshi or 0,05460 mBTC.
This is the same amount as the minimum fee recommended.
1 BTC = 1,000,000,00 satoshi
Why is there a minimum limit of transaction in bitcoin ?
This limit is not forced by the protocol but by a consensus between both bitcoin clients as well as miners in an effort to fight transaction spam
Altcoins
Altcoins are the alternative cryptocurrencies launched after the success of Bitcoin, as peer-to-peer digital currencies, that offer modifications in areas like transaction speed, privacy, proof-of-stake, DNS resolution and more, in an attempt to imitate that success.
How to solo mine bitcoin with vga
Get BFGminer 4.10.6 ( this one works for sure, i'm not sure exactly in what version they removed some option).
Download link here: http://bfgminer.org/files/4.10.6/
Get bitcoin core install and wait to download the blockchain - requires ~190GB of storage space [on 14.07.2018].
When you install the core chose to save the blockchain in other location then by default on C, for easier access. Put it in D:\Bitcoin if you have another partition or in C:\Bitcoin.
There you will have your configuration file: bitcoin.conf.
Note that depending on you internet connection it might take couple of days to fully download and sync to the network.
You cannot mine until the sync is completed.
Download link here: https://bitcoin.org/en/download
Now go and edit the bitcoin.conf file. If it does not exist just create one with notepad.
Replace the username and password with the ones you set in bitcoin core.
Go to https://www.blockchain.com/wallet and create a bitcoin wallet.
Replace the --conbase-addr with your new created wallet.
To get the address press the receive bitcoins button and you will get your address.
Run the file and I wish you good luck.
If you are lucky and win the bitcoin lottery don't forget to show your appreciation :)

If you have many computers at home or on a network and you have to connect to them remotelly using RDP you will have to change the default port and set a different one on every computer so you can then set the port forwarding rules on your wan router.
To change the default port you have to edit the registry.
Open regedit and navigate to : HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\PortNumber Change the port for ex to 3390 , 3391 etc and then set the port forward rules mapping the port to a fixed ip. You can either set the computers with fixed ip or map them in the dhcp server with ip & mac binding or Reserved IP Address. You can use check open port to check if your port forwarding is working properlly and the rpd service is listening to the specified port.
You can get this message if you restore a virtual machine, or have a raid problem and restore a raid 1 mirror from a slightly older hdd. I got and offline member for two weeks without noticing and then the second hdd when bad so i could not boot anymore.
Reactivated the offline member and changed the bad hdd rebuild the raid and then you get the error message while trying to access the domain.
Also got this but making an image of a pc in the domain and restored it a few month later to a new pc, then could not add it to domain.
You can try to remove it from domain and add it back and it should work.
Or (you need at leas Power shell 3.0 or upgrade to it if not) then run:
Reset-ComputerMachinePassword
To add a new user open cmd with administrator writes :
net user Username /add password
The user is a limited user. To give administrator writes :
net localgroup administrators Username /add
To delete a username :
net user Username /del
To change the password of a user if you cannot access any windows account. Boot from a usb and access the windows partition. Go to C:\Windows\System32\ rename sethc.exe to sethc_.exe copy cmd.exe and rename it to sethc.exe
Boot to windows, when at login screen pres SHIFT key 5 times, and instead of the sticky keys message you get a cmd with admin writes.
