Hackaday.io Traveling Hacker Box recently arrived in the mostly
rectangular state of North Dakota. It was full of numerous goodies
that any reader of Hackaday would be interested in having.
are some photos of the stuff inside:
we have a bunch of stickers.
bare BeagleLogic PCB and LCD+CapTouch board, some sort of line scan
CCD board, a bunch of random components, a couple motors, and a small
couple of standard character LCDs and some LED assemblies.
TI dev board, a couple LCDs, a PIC programmer, a busted reflow oven
controller, MAX7219 based dot matrix LED kits, an NXP dev board, and
some other miscellaneous stuff.
large selection of various integrated circuits, some large green
LEDs, vintage transistors.
bunch of small plastic boxes of integrated circuits.
MB Quart speaker crossover, Vivitar camcorder, Apple charger, Zune
MP3 player, and a little orange rover car.
bunch of Geppetto Electronics PCBs. Most unpopulated. A few GPS
oscillators, AVR programmers, PiPower boards, a Divide by 3 circuit.
panel of Crazy Clock PCBs, and an empty panel of some other small
PCB. Some smart cards to go with the card reader board, a Parallax
RFID reader and an RFID card. Another programmer board, a Cypress
PSOC development board, some addressable LEDs wired together, a
motor, and some heat shrink.
I took from the box:
Parallax RFID card reader and RFID card. I’ve never done an RFID
project so I thought this would be interesting.
BeagleBone BeagleLogic PCB. I have a BeagleBone Black board that I
haven’t done much with, so this could be an interesting project and
a chance to learn more about the BeagleBone board.
of the Max7219 LED dot matrix kits, some stickers, three Crazy Clock
PCBs (there’s 24 left), and one of the USB ISP
of the Geppetto Electronics GPS disciplined oscillator boards.
I put in the box:
of my favorite components for motor control or other high current
designs is the IXYS IXFN200N07 MOSFET. This is not your average
MOSFET. It’s rated for 70 Volts and 200 Amps. And that’s not
just a theoretical die current that you can never achieve, like with
these MOSFETs that claim ridiculous currents but come in a TO-220
package that can’t dissipate the heat that would be created if the
leads into the part didn’t melt first. These IXYS parts come in a
package called a SOT-227B, which sounds like another small surface
mount package but it’s really a large block with screw terminals on
the top. Not your average MOSFET.
could build a really high current H Bridge to control a motor, or
maybe a high current dummy load. Bolt them to an old computer CPU
heatsink and you could control a lot of current.
realized that not everything in the box has to be strictly
electronic. So I added a small bag with an assortment of terminals.
Also a few microswitches that maybe could be used as limit switches
in a 3D printer or whatever motorized device ends up being controlled
by those giant MOSFETs.
threw in a webcam PCB. It’s probably not useful for anything but I
like how you can see the whole sensor chip and the bond wires.Also
I threw in a couple PCBs with jacks for Left/Right audio, Composite
video, and S-Video. Useful for any audio project or anything that
needs a few RCA jacks.
last, but not least, I threw in a back light inverter board. It’s
an interesting design with a novel flat transformer. Maybe someone
can use or misuse it for some sort of high voltage project.
I almost forgot that I added a nice Maxxon DC gear motor. And a
couple packs of “screen wipes.” They are very nice for cleaning
anything from your phone screen to camera lenses to the LCDs in the
box had been crushed a bit in shipping so I decided to reinforce it a
bit. I glued a layer of cardboard to the inside sides of the box,
then glued pieces in the corners for double reinforcement. It should
travel better now. I had thought about replacing the box but I
thought it would be...
