Zeta flying capacitor

August 15, 2018, 7:17 am

I want to add a Pb accumulator charging capability to a power path prioritizer. Since I need to have a high-side N-MOSFET driver anyway, the Zeta topology pops up rather naturally. The specs are: ... Read more »

Quartz Wristwatch Low Battery Indicator - How it Works

August 15, 2018, 3:50 am

I've known for many years that when a quartz analog wrist watch's battery nears the end of its life many watches will cause the second hand to start making 2 or 3 second jumps, but circling aroun... Read more »

Low end 'scopes

August 14, 2018, 2:51 pm

So a Keysight rep came by and saw we were using all this (rather crappy) TEK low end 'scopes. We've got one of their loaners to play with, and I like it! 'scope is here, https://www.keysight.c... Read more »

Possibly the future in high power semiconductors?

August 11, 2018, 5:58 pm

Several years ago the semiconductor boron arsenide was predicted to have a very high thermal conductivity and now three separate groups have finally prepared crystals pure and uniform enough to c... Read more »

DSP Device for Guitar Pedal Effect

  [ 2 3 ]

I was wondering what DSP chip would be appropriate for a guitar pedal effect. I need to sample the incoming signal preferably at 96kHz perform a simple numeric function upon each sample and output h... Read more »


STmicro acceleration/magnetic sensor LSM303DLH == LIS331DLH + HMC5834?

Just had a look at the LSM303DLH datasheet and had a déjà vu ;-) It looks like ST has simply put a LIS331DLH and a HMC5843 into one package. (The HMC lacks the built-in voltage regulator) All data ar... Read more »


micropower boost circuit

I need a DC to DC boost circuit with an output defined not with respect to ground, but with respect to the input, which is variable. Output about 15 volts above the input, over a wide range -- f... Read more »


Tek TDS 744A -> TDS 784A upgrade hack!

Hi, all, Just wanted to report success in upgrading my TDS 744A scope (500 MHz, 2 gigasamples) to a much swoopier TDS 784A (1 GHz, 4 gigasamples). It now identifies itself as a TDS 784A everywh... Read more »
