This article will document the process of making OpenWRT work on the DIR-615 rev. A1.

In its dmesg, the stock firmware reports this board as "Marvell Development Board (LSP Version 0.0.102)-- RD-88F5181L-VOIP-FE".

I have managed to unbrick a D-Link DIR-615 Rev A1 back to D-Link firmware (1.00) from firmware 1.10. Allow me to describe the situation:

I recently encountered a situation while loading firmware into an Actiontec MI424-WR router, when I found myself without a bootable firmware, and the OpenRG bootloader would vehemently refuse to load .rmt files.

Conversing with your Laser Printer:(See disclaimer below)

Then copy and paste the following commands:

To access USB Host mode on the Touchpad (to plug in a Keyboard/USB Drive/etc), you need:

1. A microUSB to USB Female cable (USB-OTG cable), available on ebay for ~$3, shipped [search 'USB-OTG cable']
2. A powered USB Hub (a USB Hub with a spot to plug in an external power supply), available on ebay for under $10, shipped, with power supply  [Search 'powered usb hub']

This is gRover, the Grove-Platform Rover; it is a general, all-purpose rover for house exploration.

Foreword:

This page is a bit of a mess, I'll admit. The PDF file attached is much neater and contains much more information about the project than this page's text does. For more pictures, see the gRover Flickr Photoset. This rover build uses parts graciously provided by Seeed Studio.

Although this is an article on hardware, I'm going to be using software to probe it. This is from a 32GB HP Touchpad, though the 16GB should be the same, barring the difference in storage.

I recently purchased this Commodore 64 on eBay in a bit of Retro nostalgia. Bring on the C= hacking!

This is a nice item that I found today at Princess Auto... A grey box hiding on the bottom of a grey shelf. The phrase "Demo Kit" caught my eye, and I had to take a peek inside. I was blown away by the beautiful innards, and I just had to have it.
