Scruffy Utility towels
These thin scruffy towels are exactly what I need for drying my animals and lining pet beds. Importantly, they absorb quickly and dry quickly, and I don't worry about abusing the towels. I've also purchased the hand-towel size as mud towels for shoes and dog feet. The washcloths are ideal as general cleaning rags. I keep a couple in each bath. The scruffy nap is perfect for cleaning sinks, faucets, tubs, kitchen appliances, cars, and more.

The low-cost Atmel 8052 microcontroller is a reprogrammable solution for many types of projects
1 of 1 found this helpful The Atmel AT89C52 is a workhorse microcontroller based on the ubiquitous 8051 family of processors. Because of its popularity, a multitude of development tools, tutorials, and premade codes are readily available. This makes the device an excellent entry-level IC for those just getting into the field.
The Atmel product contains flash memory that holds its program when the power is off and that can be reprogrammed many times over. This extremely versatile general-purpose controller fits many different task-specific functions.
The Atmel AT89C52 is available in a number of different package styles (40-pin DIP, 44-pin PLCC, and 44-pin QFP) with commercial or industrial temperature tolerances. The DIP package is the easiest to work into breadboarding applications. Remember to add pullup resistors to the databus lines (many neglect to do this).
The AT89C52 can be substituted wherever an AT89C51 was used, as the main difference is that the AT89C52 offers increased memory. A higher clock-rate device can be substituted for a lower-clock device, as the rated clock speed is just the ability, not the requirement, so the same crystal will work. And the industrial temperature tolerance can be used instead of commercial. Thus, parts with better specs can be substituted for parts with lower specs and will run the same code in the same hardware.
The downside is that the AT89C52 version of the device is non-ROHS and was discontinued several years ago. Finding these devices is a boon to hobbyists and repair outfits who want an exact replacement or easy soldering.
But don't fret that your application will become obsolete due to using discontinued parts. The AT89C52 parts have been replaced by drop-in ROHS AT89S52 chips that are currently available from Atmel (recently acquired by and relabeled as Microchip). Unfortunately, the new ROHS parts require higher soldering temperatures, so the older parts are still ideal for hand repairs and breadboarding.
In using these devices over the past two decades, I have been happy with the low failure rate, the very long shelf life, and the ease of reprogramming.
