It’s not surprising that Analog to Digital Converters (ADC’s) now employ several techniques to accomplish higher speeds and resolutions than their simpler counterparts. Enter the Delta-Sigma (Δ∑) ADC which combines a couple of techniques including oversampling, noise shaping and digital filtering. That’s not to say that you need several chips to accomplish this, these days

  This year’s CES has dredged up some memories. I had assumed that as one becomes old they are supposed to become used to memories of a young vigorous person that shared their body and memories leaving little else except some scars and some old stale socks lying around plus 2 or 3 pictures to

You might notice that many of my writings start with “Back in the day”. Not wanting to disappoint I will say that back in the day we used to use wire wrap technology when we needed a somewhat solid, somewhat reliably assembly. Given a readable schematic a good tech could return a working or near-working unit in a day or two depending on the completeness and accuracy of the schematic.

I will be doing a workshop this Friday at VCF East on computer architecture. Each year is bigger and better and this is the second year for three days of computer related festivities. Worth the drive if you are in the NJ, NY, PA area!

I just did a video for Hackaday about Thermocouple Amplifiers, a quickie video feature Linear Technology in this case.  The spares from the build for the video are available at https://www.herdware.com/shop/analog/thermocouple-amplifier/ along with a Type K Thermocouple. From the Hackaday video Thermocouple is a terrific way to measure temperature. The effects of temperature change on dissimilar metals
