I need test ethereum for my pet project.
I go to https://faucet.rinkeby.io/ , put a link with my tweet with my Ethereum address in MetaMask, choose 3 Ethers / 8 hours.
The request was accepted, but 17 hours past and I haven't my test ethers.
Did I something wrong or I must wait a little longer?
And explanation me please, what exactly means 3 Ethers / 8 hours?
It's not working; it's down for a while (not sure when it's gonna come back up).
"3 Ethers / 8 hours" means that you can only request 3 Ethers each 8 hours.
You can get .001 ether here though: http://rinkeby-faucet.com/
It's not much but still better than nothing. I think the cooldown is only 1 or 2 hours.
If you want more than .001 faster they only block requests by IP, so ask a friend or something to open the link with your address and you'll get .001 more.
Many times I've received 0.1 testnet ETH from this faucet:
Rinkeby ETH
The above link will send you fairly quickly either Rinkeby ETH or Rinkeby Link or BOTH.
Also, here's an up to date list of ETH faucets:
doc.chain.link
(look for Rinkeby)

I am running the Ethereum Swarm Bee node, the minimum stake is 10 BZZ, what happens if I stake more than 10 BZZ?
For now, I am staking a minimum amount needed, 10 BZZ.
10 BZZ is the minimum stake. Staking more supposedly increases your node's chance of being selected as the "truth" in a given round and/or actually winning the round in your neighbourhood.

Does anyone know when Rinkeby Authenticated Faucet is going to start working again?
I need to add some Ether into my Metamask wallet on the Rinkbey Test Network for testing purposes, but it seems the site is not working.
I am using my Twitter to Tweet my Metamask Ethereum address and then upon copy and pasting my Tweet address in the above website, all I see is:
You can use Kovan network, and https://ethdrop.dev/ to get the ether directly.

It says the account has successfully been funded, but ETH does not show up in my wallet under the Rinkeby test network. This has happened several times over the past few days, i've tried different metamask wallets in both chrome and firefox.
It seems to be having issues. For a small amount of ETH, I suggest you to try: http://rinkeby-faucet.com/
This will give you .001 Rinkeby Testnet ETH.
is it possible that your import the accounts from ganache. And are trying to send test ETH from faucets t that account. Those accounts don't exist on rinkeby only on your private network. Try creating a new account in metamask and send some ETH there.

I just installed Ethereum wallet as I wanted to try out the Ethereum platform. I created an account and connected to the test network RINKEBY. I used the following faucet to send me some test ethers:
faucet.ropsten.de:3001
It says that it has dispatched me 3 Ether's but I could never see them in my wallet. Here is a screenshot of the wallet:
Any ideas what the problem could be?
Add a Ether from Rinkeby test Network:
Follow the steps for add a free test network - Ether to your wallet:
copy a address of your Wallet(Eather wallet/Metamask)
open this : http://rinkeby-faucet.com/
Add your address to this link.
And finally you get free Ether for your test Wallet.

I'm looking for an explanation of gas usage in Ethereum. What is it, how is it calculated, and what value does it have?
In Bitcoin, every transaction creates the same amount of “work” for the network. In Ethereum, different transactions have different costs to the network in storage, processor and memory usage, so these transactions need to be “charged” accordingly. Best official(ish) explanation I’ve found is here (“gas” vs “gasprice” is the first bullet):
https://github.com/ethereum/wiki/wiki/Design-Rationale#gas-and-fees
Currently (11/20/15) the max gas one can spend with a transaction is 3141592 units. The minimum price per unit is 50000000000 wei. (0.00000005 ether). So, the amount of ether sent as gas in a sample tx might go like this:
3141592 units * 50000000000 wei/unit = 157079600000000000 wei (0.1570796 ether).
Example use (https://github.com/fivedogit/solidity-baby-steps/blob/master/contracts/58_indexOf.sol):
indexof.indexOf.sendTransaction("I am cool", "cool", {from:eth.coinbase,gas:3141592, gasprice:50000000000});
Think of it this way:
gas/startgas = "gas units"
gasprice = "wei I'm willing to pay per unit"
Whatever gas is spent executing transactions is paid to the miner of the block containing the transaction.
Note: Gas and Ether are ultimately the same thing. What makes gas “gas” is how it’s used -- as payment for a transaction.
UPDATE: 12/8/2015: Unused gas is automatically and immediately refunded.
