The first prototype ZonCoffee v3 boards have arrived and are nearly up and running. I’m currently porting the code over to Arduino 1.0, as this board uses the Arduino Leonardo bootloader. Read on past the break for more info on the new board.

Repairing a Sigma 24-70 EX Lens
I acquired a free Sigma 24-70 f/2.8 lens that had a few issues–namely, autofocus was broken and the zoom was incredibly hard to turn. After using the lens in full manual for a while, I determined that I would attempt to repair it.

DIY Cheap Reservoir Irrigation
When you’re trying to grow a bunch of plants in a field where a water source is lacking, things can be a bit tough. Hauling water on-site is a very arduous process, even with a tractor/trailer full of buckets. After hauling 5-gallon buckets to water blueberry bushes for months, we began to work on a better reservoir irrigation system that was cheap and easy to automate with expandable capacity.

MNL: Networked LED Lighting
MNL is a multi-node high-power RGB lighting system. It consists of a controller (PC or embedded system) and multiple light nodes networked with RS485. The first prototype nodes are up and running, and we will be developing the second revision of prototypes in the coming months. Read on past the break for more information.

PCB Desktop Background
Want a nice hearty printed circuit board desktop background? Well, here you go (right-click, save as). The PCB is an older Arduino NG board placed on top of one of our 10W MNLC lighting nodes (still under development, more information to come).

tinyRGB – an i2c LED driver
tinyRGB is a minimalist blinkM-compatible high-current i2c RGB LED controller consisting of only 10 basic components. The board is small and inexpensive, can be fabricated for as little as $1/board, and can easily be assembled by hand with a total component cost of around $3.

RGB Multi-Node Lighting
This project uses the open-source i2c RGB LED controller firmware “cyz_rgb” to create a modular high-power lighting network. The network is controlled by an Arduino, which scans the network for nodes controls them autonomously with onboard scripts, manually via serial console control, or over the serial computer-control interface for interaction with programs on a host machine.

SlatePermutate
SlatePermutate is a PHP and Javascript-driven interface for college class scheduling. SP parses course identifiers (such as MATH-2500) and autofills all available sections associated with the course. After submission, SlatePermutate presents a tabbed interface of all possible schedules, course conflicts excluded.

Downloading wget Without wget: Use bash
There are many ways to download and install wget without having wget itself installed. For example, one can use curl, a sort of competitor to wget, or a package manager with libfetch or some other library-level downloader integrated (such as pacman). One may be able to use SSH’s scp or sftp utility or even use netcat to transfer a wget tarball over a network. But these methods of obtaining wget are not always feasible or even possible whereas a bash shell and a few core utilities are often readily available.
