It is a fantastic printer for the price. Things were going great until it came time to replace the toner. At the time, the price of a full set of toner cartridges was around $150. To put things in perspective, the printer itself could be acquired for less on eBay. Not being the type of person who so easily bends to the will of “The Man”, I set out on a journey to find a cheaper source of toner. A “journey”? How Stuff Works Since I last purchased a laser printer (my circa 2001 LaserJet 1200 is still kicking) the industry has changed. Why does this matter, you ask? This causes two problems.
Unsurprisingly, I am not the first person to try to address this problem. Sniffing After doing some homework, I decided to try watching the I²C traffic with a logic analyzer to see what memory locations were getting updated on the EEPROM after each print. I wrote an Arduino sketch to dump the entire memory of the EEPROM to the serial port. Notes. Elektronika.ba. PCB Heaven. Your Electronics Open Source | Share for life!

This is a daily weblog about my experiments based on the mix of electronics and computing called “Physical Computing”. I’m building little “sensor nodes” to measure electricity use, temperature, light, etc. which they transmit wirelessly to one of the central computers in the house. One goal is to better understand how we’re using electricity and how we’re heating the home, so that we can try to improve on it. We’ve achieved a roughly 15% reduction in the past few years, simply by paying a bit more attention to everything. There’s still a lot to do, particularly with gas consumption, as our house is fully open and very hard to heat locally. There is used to be one new post every day at midnight.
Update – as of November 2014, I’m pleased to announce that the weblog has been resumed, but with a slightly different setup and frequency. There are three other websites associated with this weblog: Explore! Oh, and enjoy your visit, -jcw.
