  1. JimB replied to the thread First time oscilloscope help.

    I thought that someone would pick up on that, which is why I mentioned it. The D75 is not in daily use and only comes out to play when...

    I did send BK Precision a message using their support site basically begging for a copy of the user manual. No word back yet. They...

  3. cihs liked JimB's post in the thread First time oscilloscope help.

    To expand a bit on my earlier post, I dug out my old Telequipment D75 'scope, and displayed the calibrator waveform: [ATTACH] Looking...

    Didn't try, honestly. How about the BKprecision Support Site? They do want a bit of info from you, but you'd think that site would...

  7. cihs replied to the thread First time oscilloscope help.

    Ahhh, yes. Indeed, I chose the clock pulse because it wasn't square. You have provided me with very good information. From everything...

  8. ronsimpson replied to the thread Interfacing Raspberry Pi with Keithley 3390.

    Please define "capture". Do you want the Pi to look at the coax output of the Keithley and measure the voltage? [IMG]

  9. Nigel Goodwin replied to the thread First time oscilloscope help.

    Sorry if I confused you, I was referring to the image from post #8 (which I quoted from), which isn't a square wave - hence the sides...

  11. Robo_Pi replied to the thread ESP8266-01 Question..

    I just bought a bunch of STM32 boards. I'm only just learning about them. I'll probably end up replacing the Arduino boards with...

  12. Cicero rated Nigel Goodwin's post Agree in the thread Question about wearable device with wifi connection.

    Try an ESP-01 - much smaller than a 32, which is a pretty large device.

  13. Cicero replied to the thread ESP8266-01 Question..

    Nice sounds good. One of my projects interfaces the ESP with an STM32 via serial. I made the STM the master, and the ESP a slave,...

    the bottom op amp die looks like an LM1458, definitely the layout and thermal design National Semiconductor use in their op amps.
