Good day! When you are ready on your dumpster dive to reach, I assumed I might offer you a preview of what you could obtain. Keep 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 might 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 received.
Trying contained in the tin container
The tin seems to be a Breadboard Mates Stand. Every little thing seems 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 a number of 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 equipment. A single resistor with an element 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 baggage in it? I feel these will need to have been components for the Otto, however I’m undecided. The Otto board with Nano seems like it will be nice for tasks of all kinds, however I don’t have one in thoughts but. The encoder boards can be excellent for numerous interactive tasks, however I’ll make certain 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 at present 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 automotive opens all kinds of prospects. Need 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 every part…
It’s a FreeSoC2 Improvement board. This can be a PSoC5LP ARM board with two onboard processors. However the debugger port seems to be broken.
Sure, the debugger port has seen higher days. Decisions are to restore or take away and use with out the USB debugger port. Sadly the debugger port is used to add packages, and even serial information is shipped from the processor by way of this USB port. The very best plan of action is to take away the USB connector and see if the pins are salvageable and in that case reinstall or exchange the USB connector. In any other case you’ve gotten a pleasant piece of SparkFun artwork on your desk or wall!
Hiding beneath every part 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 undertaking it’s a fantastic ESC.
All of the components for the ESC had been included, and nothing has been used. The bundle has been opened, however every part 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 received “sprinkled” into the field together with an OpenMV digicam — Let’s have a look at that in additional element.
OpenMV digicam up shut
Bent pins, nevertheless it doesn’t look too unhealthy? It’s an older OpenMV-H7 R1, however nonetheless a very good 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 every part works.
Whole Field Price- $30+Delivery
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 unused
FreeSoC2– $99.95 or $0.00- Backordered, however the board does have harm, so worth could also be ZERO
Mini FOC ESC– $134.95- Appears unused
OpenMV-H7 R1– $65.00- Retired
Whole- $592+ or $492+
I didn’t add in a number of the smaller objects just like the LEDS and switches to the overall.
The varied bins are populated by weight, so every field may have at the least 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 very random field, and that is what I received**.
** 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 together with your dumpster dive, and please share what you bought!
