Show HN: Icepi Zero – The FPGA Raspberry Pi Zero Equivalent (❄️ Score: 150+ in 2 days)

Link: https://readhacker.news/s/6vdz7
Comments: https://readhacker.news/c/6vdz7

I've been hacking away lately, and I'm now proud to show off my newest project - The Icepi Zero!
In case you don't know what an FPGA is, this phrase summarizes it perfectly:
"FPGAs work like this. You don't tell them what to do, you tell them what to BE."
You don't program them, but you rewrite the circuits they contain!
So I've made a PCB that carries an ECP5 FPGA, and has a raspberry pi zero footprint. It also has a few improvements! Notably the 2 USB b ports are replaced with 3 USB C ports, and it has multiple LEDs.
This board can output HDMI, read from a uSD, use a SDRAM and much more. I'm very proud the product of multiple weeks of work. (Thanks for the pcb reviews on r/PrintedCircuitBoard )
(All the sources on github under an open source license :D)
PS. See some more pics on reddit https://www.reddit.com/r/FPGA/comments/1kwxvk8/ive_made_my_f...

Ask HN: Anyone making a living from a paid API? (Score: 151+ in 15 hours)

Link: https://readhacker.news/c/6vnGb

Are there any solo devs or small teams out there genuinely paying their rent from selling API access?
What's your API? How much MRR? What's your pricing model? How did you find your first paying customers? And most importantly - what problem are you solving that people will actually pay for monthly?
Bonus points if you can share:
- Your biggest challenge (rate limiting? customer support? competition?)
- Whether you'd do it again
- Any "I wish I knew this before starting" wisdom
