Hi there! While you’re ready on your dumpster dive to reach, I believed I’d provide you with a preview of what you might obtain. Bear in mind the dumpster dive is a bunch of random stuff, so nothing is assured! You’ll not get the very same objects as on this field. No assist is supplied, so what you get is what you get. You may even get an enormous roll of SMD resistors…… simply kidding! It’s Christmas Morning so let’s begin unwrapping!

Time to Dive In!!

I spy an Otto Field, a Macchina AO and a tin with stuff.. and what’s that between the Otto and the AO? Lets see what we received.

Wanting contained in the tin container

The tin seems to be a Breadboard Mates Stand. All the pieces appears to be like to be there, however I’ve no show like a TIM-130 to check it with. So, I classify this as attention-grabbing however of not a lot use proper now.

Time to see what’s within the Otto Field!

So, there are a few of the contents of an Otto just like the board on the decrease left, servo horns, cables, and such. However the different objects are usually not from the package. A single resistor with a half quantity 17994 on it. A free pcb speaker, 4 of the Sparkfun Photodetector Breakout – MAX30101 (Qwiic) sensors, a Sparkfun Qwiic PIR sensor, a Sparkfun Qwiic HAT and 5 encoder boards with RGB and final and positively not least.. a plastic bag with 6 smaller plastic luggage in it? I believe these should have been components for the Otto, however I’m unsure. The Otto board with Nano appears to be like like it might be nice for initiatives of all types, however I don’t have one in thoughts but. The encoder boards can be excellent for numerous interactive initiatives, however I’ll be certain they’re the identical mannequin that Sparkfun usually carries and get the breakout boards for them. The PIR and Photodetector boards, unsure but… but when the PIR sensor works it’s the ultralow energy model so excellent for a battery operated safety sensor.

Time to take a look at the AO Field!

That is the Macchina A0 OBD-II Improvement Module at the moment on backorder at Sparkfun. How did this find yourself within the Dumpster Dive? Unsure, because it seemed just like the field had by no means been opened, nevertheless it’s exhausting to inform. It’s in actually good situation, and having the ability to have an ESP32 that may speak to your automotive opens all types of prospects. Wish to detect your pace and activate an alarm should you go too quick? Join one other ESP32 by way of esp-now and you may make it occur! 😉

Buried beneath all the things…

It’s a FreeSoC2 Improvement board. This can be a PSoC5LP ARM board with two onboard processors. However the debugger port appears to be like to be broken.

Sure, the debugger port has seen higher days. Selections are to restore or take away and use with out the USB debugger port. Sadly the debugger port is used to add applications, and even serial information is distributed from the processor by way of this USB port. One of the best plan of action is to take away the USB connector and see if the pins are salvageable and if that’s the case reinstall or exchange the USB connector. In any other case you might have a pleasant piece of SparkFun artwork on your desk or wall!

Hiding beneath all the things is a VESC Pace Controller

This can be a Mini FOC ESC primarily based on VESC6. It’s not large enough to make use of with a 1/tenth scale automotive (solely 20A steady, 40A peak at 48 volts) however for a smaller scale automotive or another brushless motor primarily based challenge it’s an ideal ESC.

All of the components for the ESC had been included, and nothing has been used. The package deal has been opened, however all the things is able to use with a bit of meeting. The clear plastic within the decrease left is shrink wrap to place over the ESC as soon as it’s assembled.

The left over bits..

Appears some LEDS, a joystick knob and a pair switches received “sprinkled” into the field together with an OpenMV digicam — Let’s take a look at that in additional element.

OpenMV digicam up shut

Bent pins, nevertheless it doesn’t look too dangerous? It’s an older OpenMV-H7 R1, however nonetheless digicam!

A minute later, and the pins are again to regular

Right here is the breakdown of the worth on the field I obtained, assuming all the things works.

Complete Field Value- $30+Transport

Otto DIY Builder Package– $30- lacking objects so simply guessing

Breadboard Mates Stand– $22

Photodetector Breakout MAX30101– $22.5 x 4

PIR Sensor– $33.50

RGB Encoder– $4.95 x 5

Qwiic Hat– $6.50

Macchina AO– $84.95- Appears to be like unused

FreeSoC2– $99.95 or $0.00- Backordered, however the board does have injury, so worth could also be ZERO

Mini FOC ESC– $134.95- Appears to be like unused

OpenMV-H7 R1– $65.00- Retired

Complete- $592+ or $492+

I didn’t add in a few of the smaller objects just like the LEDS and switches to the whole.

The varied packing containers are populated by weight, so every field may have a minimum of 1LB of components in it. Your field might have a lot much less worth, or might have extra. Once more, that is random so don’t count on everybox despatched out to be this good. I particularly requested for a totally random field, and that is what I received**.

** Okay, so the primary field picked for me had a Nvidia Jetson Nano in it. A special one was picked so another person can get that Nvidia Jetson Nano! 😉

Good luck together with your dumpster dive, and please share what you bought!
