Put my old laptop to work
An old laptop on Wi-Fi can earn in small ways today: run Grass to share spare bandwidth, label data on Perle Labs, or help train robots with BitRobot. Too slow for Windows? ChromeOS Flex can revive it for free. All are free to join; you pay only the electricity. Skip these: copycat claim sites.

Chapter 1
Who knew?
A laptop that is simply plugged in and on Wi-Fi can be enough to take part.
A laptop too slow for its old Windows can often be revived for free with ChromeOS Flex or a light Linux.
Grass paid its Stage 2 rewards in USDC rather than its own token.
The same spare machine can help train robots, not only share internet.
You need mining rigs and big power bills.
Joining is free. A laptop usually draws far less power than a desktop, so the electricity cost is small but real; check your own tariff.

The free route, step by step
3 stops, cheapest first
Three ways through
Pick your route
- Start free tonight
Plug it in and share bandwidth
The easiest start: install, leave it on, watch.
- Let a DePIN network use your spare internet
- Revive a slow machine with ChromeOS Flex if needed.
Cost Free; your electricity.
- The bold play
Sell its whole brain, not just its bandwidth
Put Linux on it and rent spare CPU on Golem, then label data or help robots when you sit down.
- Rent your spare computer to the Golem network
- Label data that trains AI and get rewarded for accuracy
- Help train robots and get points for it
Cost Free; your electricity and an hour of setup.
- Build it
Build the one-boot node image
Built by the HouseNobody ships a USB image that turns any old laptop into a Golem and bandwidth node in one boot. That is a gap the House will build with you.
- Own a working onchain app with your name on it
- Package the Golem installer and a bandwidth app into one bootable image.
Cost Build time.

Combos nobody marketed
- ChromeOS Flex+Grass=
A dead Windows laptop becomes a light, always-on bandwidth node.
Why it works Flex is free for many older PCs, and Grass uses bandwidth, not heavy compute.
- Perle Labs+BitRobot=
The same machine shares bandwidth idly and earns from your own labelling and robot tasks when you sit down.
Why it works Idle and active tasks do not compete for the same resource.
- Golem+Grass=
CPU and bandwidth both earn from the same idle machine.
Why it works They sell different resources, so they rarely compete.
- Mysterium node+a home connection=
Your spare bandwidth serves VPN users for MYST.
Why it works Mysterium pays nodes by the bandwidth they supply; check local rules first.

Chapter 4
Where it matters most
- students in Lagos and Manila
Spare hardware is common and paid online work is scarce.
- retirees
A set-and-forget app fits a quiet routine.
- households with unlimited home internet
The bandwidth is already paid for every month.

Questions
Does running Grass on a laptop cost money?
Grass is free to join; the only costs are your electricity and the bandwidth you already pay for.
Is it safe to run Grass on an old laptop?
Install Grass only from its official site, keep the laptop updated and avoid copycat claim pages.
How much can an old laptop earn with Grass?
There is no fixed amount; Grass rewards depend on uptime, region and eligibility rules, and can be zero.
Do I need a powerful laptop for Grass?
No. Grass shares bandwidth rather than computing power, so an old laptop on Wi-Fi is usually enough.
If your old laptop could earn while you sleep, what tiny thing would you let it pay for first?
