A Digitally Controlled Dual Tracking Power Supply — III
In part 1 of this series of blog postings, I showed my preliminary design of a dual tracking linear power […]
A Digitally Controlled Dual Tracking Power Supply — II
In my previous post, I showed my design of a dual tracking ±30V linear power supply. My goal was to […]
A Digitally Controlled Dual Tracking Power Supply — I
Power supply is one of those things one can never have too many of. I have quite a few already, […]
Using LTC1100 As Precision Voltage Adapter
A while ago, I built a precision voltage adapter using LMP8358. In this post, I will show you a similar […]
Building a Constant Current/Constant Power Electronic Load
A while back I built a simple constant current electronic load using an aluminum HDD cooler case as the heatsink. […]
Interfacing TLV5620 With Arduino
TI’s TLV5620 is a budget 4-channel 8-bit DAC. While it is designed primarily for running with a power supply between […]
An Isolated DAC Using PWM Output
Arduino‘s (ATmega328P) PWM outputs via analogWrite can be conveniently turned into analog voltage levels through the use of simple RC […]
Fixing a Global Specialties 1301A Power Supply
One of the things I love to buy from eBay is linear power supply. Labs and industries routinely clear out […]
Yet Another Semiconductor V/I Curve Tracer – II
In my previous post, I showed my design of a semiconductor V/I curve tracer and discussed its theory of operation […]
Yet Another Semiconductor V/I Curve Tracer – I
Semiconductor curve tracers were frequently used in analog circuit designs many decades ago, at a time when discrete semiconductor devices […]
UPS Transfer Time Measurement
Most offline/line interactive UPS‘ (Uninterrupted Power Supply) have a transfer time between 5 to 15 milliseconds. In this post, I […]
Tektronix 2213 Teardown Pictures
I love old Tektronix analog oscilloscopes and I could not seem get enough of them. So when I saw a […]
Variable Power Regulator Using TPS5420
I typically use linear regulators (e.g. 7805, LM317, etc.) in my projects. Linear regulators (especially the low dropout ones) are […]
Using REF200 As 100uA Precision Reference
A few weeks ago, I discussed how to calibrate middle to low end DMMs using a precision voltage reference such […]
VFD Clock – Putting Everything Together
After I completed the filament driver and the circuit to drive the multiplexed VFD segments, it is time to finish […]
