Canon AE-1 Kit

Canon AE-1 body with the standard Canon 50 mm lens. Also includes a Canon 70 – 150 mm zoom lens, and a CPC 28 mm macro lens. I also have the original AE-1 manuals and a nice Lowepro Nova 1 case for all of the kit.


Tektronix 7603 Oscilloscope Mainframe

I’ve had this old warhorse for a while, but never seem to need it now that I have a DSO with decent specs. Includes 7A26 dual trace amplifier, 7B53A dual time base, and 7A13 differential comparator. 100 MHz bandwith.

For local pickup only, for obvious reasons.


DDS-60 Daughtercard

An old classic. Surplus to my needs, since I’ve been using the Si5351 so heavily here now.


Tektronix TPS 2000 series LCD module

A replacement LCD module for the Tektronix TPS 2000 serious digital oscilloscopes. I picked this up at the Tek Company Store when I worked there back in the day, but I don’t think there’s much chance I’ll be needing it. Tek P/N 650-4349-01 or 119-6625-01.


Raspberry Pi Model B (V1)

The original! Comes with an laser-cut acrylic enclosure with fancy pi cutout. I have two to sell.

$10 each


Cypress CY3217 PSoC Programmer

Used to program Cypress 8-bit PSoC mixed signal controllers. Never used.


TI LM4F120 Stellaris LaunchPad Eval Kit

ARM Cortex-M4F development board. Currently out of production, but there is quite a bit of support for these TI dev boards.

Product page


TI TM4C124G Tiva C LaunchPad Eval Kit

ARM Cortex-M4F development board. In current production. Pretty powerful microcontroller and a fair bit of support for this ecosystem.

I have two of these: one in the original box and one without.

$10 (in box)/$8 (no box)

SparkFun Arduino Pro Mini 328 – 5V/16MHz

One of the classic Arduino variants. Remember that you need a separate USB/UART bridge to program this.

Product page



Neat little ATSAMD21-based board, I just never got around to using it much. Very tiny.



Softrock Receiver

To be honest, I’m not even sure exactly which model of Softrock this is. I can tell you that it is one of the earliest ones and that it works just fine. I have the 20 meter and 40 meter plug-in modules for it, along with crystals for 14.060 MHz and 7.030 MHz.

  1. How is the DG1022U working out. I don’t know how recent your post was but it cant be too old as the little generator is relatively new.
    I am a hobbyist and I just got a new Rigol scope. Now I want to get a small function generator. I am 73 yrs old so I am wondering how complicated the instructions will be for me. I am just getting acquainted with the scope and I think I can figure it all out. I was pondering over the idea of a used Wavetek for a couple of hundred dollars or spend $400+ for a new Rigol. aybe you can give me a few pointers about the 1022U. I have a few old receivers here that I want to experiment with sweeping the IF’s to — Just learn how to do it, I guess.
    Anyway I enjoyed reading your post. I think it is more along my way of thinking. I read a negative review on an EE website and I think a “ham review” is more of what I was looking for.

  2. Phil,

    So far I’m happy with my purchase of the DG1022U. I’ve used the basic CW signal generation purposes, and it has done that job quite nicely. When set to -50 dBm and paired with my HP step attenuator rig, it can provide a signal down to about -130 dBm or so.

    I have briefly tried AM modulation, just to see that it works as expected. It’s actually quite amazing that it gives you AM, FM, PSK, and FSK. Not to mention PWM and other pulse-train type signals. And I haven’t even touched the actual arbitrary waveform generation yet.

    There is been some concern expressed to me that since the unit is based on DDS technology, the spurious emissions might be problematic. Now that I have the DSA815, I plan on checking out how the spurs look on integer MHz frequencies, which tend to be problems in DDS systems.

    It also has a built-in 200 MHz frequency counter, which is quite handy. If you pair that with the USB connectivity, you have an automated oscillator stability measurement system.

    If you want to sweep circuits, it does have a sweep setting and a sync output, which you could pair with an oscilloscope or a spectrum analyzer without a tracking generator.

    Like I said, I have no complaints at this point, but I haven’t really put it through its paces yet.
