Make certain to take a look at the remainder of Jesse’s initiatives that he has written, comparable to making an Autonomous Garden Mower and extra!
Whats up! If you are ready in your dumpster dive to reach, I believed I’d provide you with a preview of what chances are you’ll 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 would even get a giant 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 acquired.
Trying contained in the tin container
The tin seems to be a Breadboard Mates Stand. All the things appears to be there, however I’ve no show like a TIM-130 to check it with. So, I classify this as fascinating however of not a lot use proper now.
Time to see what’s within the Otto Field!
So, there are among the contents of an Otto just like the board on the decrease left, servo horns, cables, and such. However the different objects should 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 definitely not least.. a plastic bag with 6 smaller plastic luggage in it? I feel these will need to have been components for the Otto, however I’m undecided. The Otto board with Nano appears like it will be nice for initiatives of all types, however I don’t have one in thoughts but. The encoder boards will probably be excellent for varied interactive initiatives, however I’ll be sure they’re the identical mannequin that Sparkfun usually carries and get the breakout boards for them. The PIR and Photodetector boards, undecided 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 presently on backorder at Sparkfun. How did this find yourself within the Dumpster Dive? Undecided, because it appeared just like the field had by no means been opened, nevertheless it’s onerous to inform. It’s in actually good situation, and having the ability to have an ESP32 that may speak to your automobile opens all types of prospects. Wish to detect your pace and activate an alarm when you go too quick? Join one other ESP32 through esp-now and you can also make it occur! 😉
Buried beneath the whole lot…
It’s a FreeSoC2 Improvement board. This can be a PSoC5LP ARM board with two onboard processors. However the debugger port appears 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 knowledge is distributed from the processor by means 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’ve got a pleasant piece of SparkFun artwork in your desk or wall!
Hiding beneath the whole lot is a VESC Pace Controller
This can be a Mini FOC ESC based mostly on VESC6. It’s not large enough to make use of with a 1/tenth scale automobile (solely 20A steady, 40A peak at 48 volts) however for a smaller scale automobile or another brushless motor based mostly challenge it’s an incredible ESC.
All of the components for the ESC had been included, and nothing has been used. The bundle has been opened, however the whole lot is able to use with a little bit 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 acquired “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 an excellent 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 the whole lot works.
Complete Field Price- $30+Delivery
Otto DIY Builder Equipment– $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- Seems 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- Seems unused
OpenMV-H7 R1– $65.00- Retired
Complete- $592+ or $492+
I didn’t add in among the smaller objects just like the LEDS and switches to the full.
The assorted packing containers are populated by weight, so every field can have at the very least 1LB of components in it. Your field may have a lot much less worth, or may have extra. Once more, that is random so don’t count on everybox despatched out to be this good. I particularly requested for a very random field, and that is what I acquired**.
** Okay, so the primary field picked for me had a Nvidia Jetson Nano in it. A unique one was picked so another person can get that Nvidia Jetson Nano! 😉
Good luck along with your dumpster dive, and please share what you bought!
