Hey bitcoin! I'm Lixin, longtime bitcoiner and creator of Cobo Vault.
I come from a background in the electronic hardware industry, and experienced one of my products being featured in Apple Stores around the world. Back in 2018 Cobo CEO Discus Fish, who also co-founded F2Pool, invited me to help build Cobo’s hardware product line. As we had strong ties to miners in China, we naturally designed the 1st gen with them in mind. In China, mining farms are nearly always built in very isolated places where there is very cheap wind or water electricity. When we built our 1st generation Cobo Vault hardware wallet, we needed to maximize the durability of the device in addition to its security. We used aerospace aluminum rather than plastic and made it completely IP68 waterproof, IK9 drop resistant, and military standard MIL-STD-810G durable for the mining industry.
Things changed last year when I went to Bitcoin 2019 and talked to lots of hodlers in the States. I found that 95% of them don’t care about durability. I asked them if they were afraid of their home being flooded or burned down in a fire. The answer is - yes, they are afraid of these things, but see them as very low possibilities. Even if something were to happen, they said they would just buy another HW wallet for 100 dollars. From these conversations, it became more and more clear we should design a product around a normal hodler’s needs.
Our 2nd gen product compromises on durability but doesn’t compromise on security.
Most hodlers share some needs with miners:
Aside from the legacy of the 1st gen, our 2nd gen product will have:
The amount of 200 USD has been withdrawn from your account. Accounts: U3869878->U24795174. Memo: Shopping Cart Payment. . Date: 06:31 06.07.20. Batch: 322597842Investment Plans
(1) 0–999 GH/s, 2% daily profitDeposit works according to the selected contract, and the contract is from 60 to 180 days. You should deposit money into your balance first, and then buy Hash with the money on your balance. Your initial deposit is already in your daily profit, so principal will not be returned in the end.
(2) 1000–2999 GH/s, 2.1% daily profit
(3) 3000–5999 GH/s, 2.2% daily profit
(4) 6000–9999 GH/s, 2.3% daily profit
(5) 10000–19999 GH/s, 2.4% daily profit
(6) 20000–29999 GH/s, 2.5% daily profit
(7) 30000–99999 GH/s, 2.6% daily profit
(8) 100000–199999 GH/s, 2.8% daily profit
(9) 200000–999999 GH/s, 3% daily profit
(10) 100000–2999999 GH/s, 3.5% daily profit
(11) 3000000 GH/s, 4% daily profit
For example, I buy GH/s with $200, and choose the 60 day contract. My daily profit will be 2.5% for 60 days. At the end of investment term, I will get back $300 totally($100 profit with $200 initial deposits).But there is one things you should know that you must choose which ecurrency you want to mining, or we can say like this, which ecurrency you want your daily profit to be paid to. For example, if you want your daily profit to be paid through BTC, then you should turn off all other ecurrency mining process and only leave BTC mining. You can see the mining choice on the “Mining” page of their website.

Literally my first Reddit post so please bear with me :)submitted by Legodude522 to u/Legodude522 [link] [comments]
I wanted to build an of grid solar system for me shed. I've built other systems before but this is the first time building one this big on my own. I'm not a professional electrician so please use this information at your own risk. Generally I try to over-engineer my electrical designs to make up for my incompetence. Some of the design choices may seem odd but have reasoning behind it that may not be apparent at first. A lot of the materials I used were already on hand and were either free or cheap. If you think I should have done things differently, I'd be happy hear from you but please be nice!
TLDR, Basic Specs...
(4) 100 Watt Renogy Monocrystalline Solar Panels
(6) 225AH 6V Lead Acid Golf Cart Batteries (series and parallel for 675AH 12V)
(20 ft) 2 AWG Copper Cables
(1) 1800 Watt DC/AC Inverter
(1) 60A MPPT Solar Charge Controller
I've built a mostly complete parts list here with Google Sheets. https://docs.google.com/spreadsheets/d/1ntLIxUjBPDQZN__vHUV0RzNPnzy4xBO7PRnIbkUv170/edit?usp=sharing
This is the circuit design I came up with, this should be simple enough to follow along with basic circuit design understanding. Again, I'm not a professional electrician.
Nifty circuit design
For the rest of this project overview, I figured it would be most logical to work from the top down.
I installed these brackets from Renogy. This was one of the most time consuming steps. I probably should have increased the pitch on these for optimal sunshine.
Positioning the (4) 100 watt solar panels.
I decided to run wires for each solar panel rather than wiring them in series. To save money, I bought the cheapest glands I could find, these did not come with screws or sealant. I ran 10 AWG wire through the glands and sealed the roof entry with black roofing caulk. Then applied the roofing caulk to the plastic body and screwed it down. I installed standard MC4 solar panel connectors, these are crimped and soldered.
I decided to have the glands positioned underneath the panels to provide optimal protection from the elements and a cleaner look. Having another set of MC4 connectors here also makes it easy to change panels or reconfigure my setup later on.
The wires from the roof drop in like this. I used simple cable tacks to secure them. I split the positive and negative wires to run along separate boards.
Working off of my initial circuit design, I worked up the placement of the components on the main power panel. Solar would come in on the top and the batteries would be connected to the bottom.
These busbars were some of the most expensive components but worked very nicely for my application.
I ran ground wires along the backside to ground the components and mounting bolts. These connect to the MPPT controller, inverter, and later on a grounding rod.
The main power panel is installed on the wall. The positive solar power leads run to a 35 Amp breaker before continuing to the 60 Amp MPPT charge controller.
MPPT up close.
At the base of this system are six 6 Volt lead acid batteries. I wired the batteries in series creating three 12 Volt battery banks and then wired them in parallel on the main power panel busbars.
I used 2 AWG copper wire and crimped on lugs for for the batteries and inverter leads.
I can now easily power my iMac, power my soldering iron, charge my drill batteries, charge my lawn mower battery, and power my LED lighting.
If you ever wanted to know if I can mine bitcoins on this rig, the answer is not really. This lasted for about 12 minutes before low voltage shutoff on the inverter. The 2 AWG leads going to the inverter got warm!

Bitcoin mining difficulty will usually only drop if Bitcoin prices do, but if that happens then your Bitcoin is worth less, which also pushes back the break-even point. As such, even if a cloud mining contract looks like it will be profitable, you’re still more likely to lose more than you earn.
