Cryptocurrency mining no longer needs to be dominated by giant ASIC rigs and massive power bills. My setup uses four Raspberry Pi miners running Yescrypt CPU mining, combined with several NMMiners (USB SHA-256 miners) on Zpool, all auto-converting rewards into Ravencoin (RVN).
This system is built for:
Low cost
Low power
High uptime
Slow and steady RVN accumulation
Below is the full breakdown.
1. Hardware Overview
Raspberry Pi CPU Miners
Device | Model | Miner | Algo | Pool | Output |
|---|---|---|---|---|---|
Pi #1 | Pi 5 | cpuminer-opt | Yescrypt | Zpool | RVN via auto-convert |
Pi #2 | Pi 5 | cpuminer-opt | Yescrypt | Zpool | RVN via auto-convert |
Pi #3 | Pi 4 | cpuminer-opt | Yescrypt | Zpool | RVN via auto-convert |
Pi #4 | Pi 3 | cpuminer-opt | Yescrypt | Zpool | RVN via auto-convert |
All Pis run Yescrypt because it is the most efficient CPU-friendly algorithm for low-watt hardware.
NMMiners (USB SHA-256 Miners)
Hashrate per unit: 300–350 KH/s
Power usage: ~5–7 watts each
Pool: Zpool
Output: RVN via auto-convert
Combined, they add nearly 1 MH/s of SHA-256 hashing into the same RVN pool.
2. Why Mine Yescrypt on a Pi?
Efficiency per Watt
Pi Model | Hashrate (Yescrypt) | Power Draw | Efficiency |
|---|---|---|---|
Pi 5 | 2.4–3.1 KH/s | 10–14W | ~0.22 KH/s per watt |
Pi 4 | 1.4–2.1 KH/s | 7–8W | ~0.20 KH/s per watt |
Pi 3 | 0.8–1.3 KH/s | 6–7W | ~0.16 KH/s per watt |
Total Combined Hashrate
All Pis together:
≈ 6–8.5 KH/s Yescrypt
This is extremely efficient considering the small power footprint.

3. Why Convert Everything to Ravencoin (RVN)?
Zpool lets you mine any algorithm and get paid in any supported coin. That means:
Mine Yescrypt (CPU-friendly)
Mine SHA-256 with NMMiners
Get all rewards converted into RVN
Why RVN?
Lower difficulty than BTC/BCH → easier to accumulate
High liquidity on multiple exchanges
Strong long-term fundamentals
Perfect for low-power, slow accumulation mining
4. NMMiners: Extra Hashpower for the Same Goal
NMMiners aren’t strong enough to chase Bitcoin, but they shine on Zpool:
They submit constant low-diff shares
Zpool converts those shares into RVN
Their watt usage is microscopic
Expected Output
Metric | Value |
|---|---|
Total SHA-256 Hashrate | ~900 KH/s – 1.05 MH/s |
Daily Shares | 240–320 per hour combined |
Expected RVN/day | 0.25–1.1 RVN |
Even as “tiny miners,” they still contribute meaningfully because Zpool smooths the payouts.
5. Combined Daily RVN Estimate
Taking into account:
Yescrypt difficulty
Zpool profitability rotation
SHA-256 share contribution
RVN market price fluctuations
Your realistic RVN accumulation looks like:
RVN Per Day Estimates
Low: 0.4 RVN/day
Normal: 0.8–1.5 RVN/day
High volatility: 2–3 RVN/day
This is achieved with under 40 total watts of hardware.
6. Why This Setup Works Financially
1. Ultra-Low Power
Most of the system:
Runs on small USB chargers
Can run off a battery bank or solar
Costs almost nothing to maintain
2. Mine Where CPUs Perform Best
Yescrypt is one of the last CPU-friendly profitable algos.
3. Auto-Conversion Maximizes Profit
You don’t chase algorithms;
Zpool does it for you.
4. Multiple Small Miners → One Strong Reward Stream
The Pis + NMMiners produce a constant drip of shares that accumulate into RVN.
5. Perfect for Long-Term Stacking
Even small daily amounts become massive if RVN rises:
- $0.02 → $0.20 → $2.00+ potential
