Very important note: once you get access to your Pi, do regenerate the SSH keys.
Since Raspbian (and basically all the other distributions) are distributed as prepared images to copy onto the SD card, it is not safe to keep the default SSH keys.
To regenerate the keys proceed as follows:
# sudo rm /etc/ssh/ssh_host_*
# sudo dpkg-reconfigure openssh-server
Updating and Upgrading Debian Raspbian “wheezy” Linux Distribution
Before you begin to install any software it’s best to make sure the package index files are up-to-date (essentially just a file pointing to the latest version of compatible software – for example when we install VNC later in the guide). Make sure you have an internet connection and run the following command. It may take a few minutes.
sudo apt-get update
sudo apt-get upgrade
Now’s also a good time to make sure the whole Linux distribution is up-to-date. You can do this now, or later (it may take a while). Again make sure you have an internet connection and run:
sudo apt-get dist-upgrade
You can run these commands every now and again to make sure you have the latest software. If you’re asked to confirm anything, just hit ‘y’ on the keyboard.
Similar to my first workbench, I needed to create a 2nd.
A couple of differences though:
- Meant to hold a miter saw
- 2nd table’s height was designed so that with a miter saw on top, the top of the miter saw is flush with the top of my first workbench
- Table dimensions are smaller
- Added a lower shelf
Here’s the basic design:
- Same basic materials as my first workbench
- Used 8 Strong-Tie connectors this time though
- Originally got a 4′ x 8′ sheet of plywood from the first workbench, so re-used leftovers for the top and shelf
- Lower shelf is against the lower crossbars
- Meant to hold a shop-vac, with the intention of hooking it up to my miter saw
- Added middle crossbars, similar to the plans of that inspired my design, but did not use that for the shelf support.
- Long bars only have 2 screws into the brackets on left and right sides (none on the inside). This is to allow the bars to be removed easily for access.
- Used pronged tee nuts and associated hardware to secure miter saw
Got tired of not having anywhere to put things down and work on them in my garage. Its a single car garage and is mainly used for storage. Its never seen a car before. Aside from storage though, I of course keep my tools there.
So I did a bit good of Googling and found a bunch of options around, but settled on a simple design that is reinforced by some metal brackets.
Here’s my basic design.
- 3/4 plywood
- 4 x casters (Lowes)
- 4 x Simpson Strong-Tie 2×4 Rigid Tie Connector (Home Depot)
- 2 x Box Simpson Strong-Tie Strong-Drive Screws #8 (Home Depot)
- Other wood screws for top to frame (1 5/8″ I think)
- Does not show brackets, but only used 4. 1 for each top corner
- Unlike the plans I found, did not build with a bottom shelf. It is still very sturdy though
- Above plans show 2 plywood pieces on bottom of the frame. Ended up not doing that… But the concept would be a partial torsion box, which adds strength… If needed.
- Could only find casters with small enough connection heads at Lowes
- Simpson Strong-Tie products needed were only at Home Depot
- Top board overhangs frame by 2″ on each long side. Flush with short sides. Personal preference though. My thinking is that it will give me something to clame against.
- Be sure to countersink screws
- With overhanging sides, added aluminum corner brackets along the length. This should help prevent the long plywood side from splintering.
- Planning to add a power strip of some kind… Somewhere. Still trying to figure out best way to implement.
