Lately I got some used Cisco Meraki MR33 access points to upgrade my wireless network. Most of them came with a locked bootloader, which prevents me from flashing my own OpenWrt images, so removing the NAND and reprogramming it offline was necessary. This post documents the entire flashing process, some of the difficulties I dealt with, and provdes a simple replacement mounting bracket design for anyone who needs it.
I needed a wireless serial console adapter, so I reused some old portable routers to make some. This post explains my rationales behind this choice, documents some hardware upgrades I had to do on a few portable routers, the firmware building and flashing process, and some alternative solutions I have found while doing my research.
The Wyse 3040 thin client only comes with 8GB or 16GB of onboard eMMC storage with no options for expansion. I wanted significantly more storage than that, so I upgraded the eMMC with a 128GB one, and reused the 8GB one I removed to make a flash drive.
