We're trying to bootstrap a new DIY hardware market for Bitcoin users at
https://www.tindie.com/m/bitcoin/If you have any custom hardware that you've developed, please list it for sale. If you know anyone with a hardware project, please pass along this post.
Have any ideas for hardware you'd like to see developed? Discuss it here!
I, for one, would love to see an all-in-one plug and play Bitcoin node with its own Web UI for configuring and updating the node software. Bonus points if it supports bandwidth throttling.
