Interfacing ADS1224 With Arduino

ADS1224 is a 24-bit delta-sigma analog-to-digital converter with 4-channel differential inputs multiplexer. This ADC chip offers a 20-bit effective resolution (6 to 7 digits of resolution in full scale), which makes it ideal in high-resolution voltage measurement applications.

“Program Will Not Fit Into Available Memory” Error In CCS

I upgraded my Code Composer Studio (CCS) to 5.2.1 a few days ago. An interesting thing I found out was that while building existing Lauchpad projects, I was receiving a “program will not fit into available memory” error: Continue reading ‘“Program Will Not Fit Into Available Memory” Error In CCS’ »

Bring a Dead WD1001FALS Back to Life

I have a few Western Digital WD1001FALS 1 TB hard drives and they have been pretty reliable for the past few years until recently. One of my WD1001FALS’ died suddenly a few months ago. Since it was still under warranty, I sent the dead drive back to WDC and swapped for a replacement drive. A couple of weeks later however, another drive failed in a similar manner (the harddrive would not spin up). Instead of sending it back for another RMA, I decided to take a better look at what was causing the failure and see whether I could fix the drive myself.

Adding a Fan Controller to Topward 6603A

I did a review on Topward’s 6603A linear power supply last time. In my opinion, Topward 6000 series power supplies are really well made and offer exceptional performance. One minor annoyance though, as I mentioned, is that the two cooling fans are constantly on. This makes the otherwise great piece of lab equipment rather noisy, even when the load is light.

Topward 6603A Linear Power Supply Teardown

I bought a used Topward 6603A lab power supply from eBay a couple of weeks ago and thought I would do a quick review and teardown and perform some basic measurements to see how well it was built. Continue reading ‘Topward 6603A Linear Power Supply Teardown’ »
