HackerBox #0025: Flair Ware

I still need to work through HackerBoxes #23 and #24, but #25 arrived on the 1st. I’ve been spending so much time putting together my workshop that I haven’t sat at my electronics desk much in the last 2 months.

The camera was a little too close for the view angle I had set. I need to build a better camera arm/rig too.

I tried to price things out, but there are a lot of custom things in this box. Prices are from Amazon Prime unless noted. This list was copied from the Instructable for HackerBox #25.

  • HackerBoxes #0025 Collectable Reference Card – $1 (estimate)
  • LED Star Wearable Kit – $5 (estimate)
  • Color-Cycling Sign Kit – $5 (estimate)
  • BitHead ATtiny85 Wearable Kit – $5 (estimate)
  • Pluggable Digispark DevBoard – $3.08
  • Extra ATtiny85 8DIP Microcontroller – $1 (estimate)
  • CJMCU LilyTiny Digispark Module – $8.68 (AliExpress)
  • Three LilyPad NeoPixel Modules – $11.85 (SparkFun)
  • LilyPad Coin Cell Module – $1.95 (SparkFun)
  • CR2032 Lithium Coin Cells – $3.19
  • USBasp Atmel AVR USB Programmer – $5.79
  • Green Prototyping Board 4x6cm – $0.25 (estimate)
  • Lapel Pin Backs – $1 (estimate)
  • Shrink Tubing – 100 Piece Variety – $2.36 (AliExpress)
  • Tin Project Box – $1.02 (AliExpress)
  • Exclusive HackerBoxes Decal – $1 (estimate)
  • Exclusive HackerBoxes Knit Cap – $10 (estimate)

With a lot of estimates I get a total of $67.17. Since I’ve been pricing these out all but once I’ve come up with a $60-70 value. Consistent.

HackerBox #0024: Vision Quest

A quick unboxing of HackerBox #0024: Vision Quest.

Prices I found online (Amazon Prime unless noted):

  • HackerBoxes #0024 Collectable Reference Card – $1 (estimate)
  • Three Bracket Pan and Tilt Assembly – $19
  • Two MG996R Servos with Accessories – $18 ($9/ea)
  • Two Aluminum Circular Servo Couplers (included with the pan and tilt kit above)
  • Arduino Nano V3 – 5V, 16MHz, MicroUSB – $3.99
  • Digital Camera Assembly with USB Cable – $10 (estimate)
  • Three Lenses with Universal Clip Mount – $3.33 (AliExpress)
  • Medical Inspection Pen Light – $2.23 (AliExpress)
  • Dupont Male/Female Jumpers – $0.50 (estimate)
  • MicroUSB Cable – $2.40
  • Exclusive OpenCV Decal – $1 (estimate)
  • Exclusive Dia de Muertos Decal – $1 (estimate)

Totals out to $62.45 but I couldn’t find the model on the back of the camera module anywhere. I wouldn’t expect that estimate to be off by more than $5 though and maybe even cheaper. The servos feel pretty hefty compared to the micro ones I have. This will be another neat box to play around with.

AdaBox 005: Break For Pi

This quarter’s AdaBox is a welcome switch away from the Adafruit feather line of boards. While I’ve created my own retro gaming device with a Raspberry Pi before, this is a nice kit with everything you need except a screen (you could use a TV). It’s a bummer that they didn’t opt for the Pi Zero W.

The box came with a set of Hammer Headers, which I’ve been skeptical about since I first saw. I have no issues soldering, actually enjoy the task, and prefer it so I have solid connections to the pins. I figured I’d give the headers a try though. Plus it was good excuse to try out the garage sale hammer I bought. Take a look at the 8x speed time-lapse…

I appreciate the idea and can see that hammer headers would be a good option in schools where they can’t have soldering irons, but I’ll never use them again. It took me 6 minutes and I felt like I was destroying the Pi Zero.

The Adafruit Joy Bonnet is a cute little add-on for the Pi. The first thing I noticed when holding it was how cheap the thumbstick feels and sounds. I wouldn’t expect much out of such a small controller that’s only $15 and snaps on to a Raspberry Pi though.


When I get my 3D printer later this year I’ll make a case for this 7″ screen I bought a couple of years ago, maybe even with a way to clip in the Pi Zero. Or better yet, a Pi 3B, which is better suited for a retro gaming device.

This is now my 8th Raspberry Pi. The 7th was named grasshopper, but what type of pie should I use for the letter H? Comment with your suggestions because the Wikipedia list I usually reference has two “H” pies I’ve never heard of.

 

From China

I placed a big AliExpress order several weeks ago for various parts to use in some project ideas. Small padded envelopes appeared in my mailbox daily for over a week, which is always exciting. I’ve been really impressed with the quality of the items for the prices.

Unboxing – HackerBoxes #0023: Digital Airwaves

I was able to avoid spoilers on this month’s HackerBox again, even though something happened with my shipping over the weekend. It arrived Monday instead of Saturday like it was originally scheduled.

Unique box. I’m excited to go through the Instructable for this box and learn some stuff about antennas and WiFi. The PVC pieces and copper wire are for making a custom antenna, which will be fun. I checked my box of goodies to see which WeMos board I had recently bought and it was the Mini Lite. I think I have one of each of their tiny boards now.

I tried to come up with a value for the box again. All prices are from Amazon (with my Prime account) unless noted.

  • HackerBoxes #0023 Collectable Reference Card – $1 (estimate)
  • USB Wi-Fi Interface Device with RT5370 Chipset – $5.89
  • WeMos D1 Mini Pro-16 – $5 + 1.81 shipping (AliExpress)
  • WeMos I2C OLED Shield – $4.50 + 1.58 shipping (AliExpress)
  • WeMos ITX to SMA Antenna Coax – $4.95
  • Exclusive PCB Yagi-Uda Antenna Kit – $5 (estimate)
  • Exclusive CPVC Yagi-Uda Antenna Kit – $1 (estimate)
  • SMA male to RP-SMA male Coax Adapter – $5 (estimate)
  • Mini Tripod with Shoe Mount – $7.79
  • USB Extension Cable – $3.35
  • MicroUSB Cable – $4.16
  • Exclusive Yagi-Uda Antenna Decal – $1 (estimate)
  • Exclusive Digital Airwaves Iron-on Patch – $2 (estimate)

This was a hard box to price out, so there are a lot of estimates. I didn’t see the PCB antenna anywhere and the parts for the PVC antenna are obviously DIY. The random bag of connectors doesn’t seem to be from a kit of any kind. There was also another antenna in my box not on this list. So I’ll add another $10, which all adds up to $64.03.

Unboxing: HackerBoxes #0022 – BBC Micro:Bit

The latest HackerBox came in the mail yesterday. I managed to avoid any spoilers so thought I’d see how dumb I can sound as I figured out what was in the box.

I’m looking forward to checking out the Micro:Bit and its blocks editor. The 128×64 OLED and WiFi modules will definitely get used in projects at some point.

Knowing the Micro:bit sells for less than $20, this box seemed light on value, so I had a look. Like last time, all prices are from Amazon unless noted.

  • HackerBoxes #0022 Collectable Reference Card – $1 (estimate)
  • BBC Micro:Bit – $16.99
  • BBC Micro:Bit Connector Breakout Kit – $5.38 (kitronik.co.uk)
  • Twin AA Battery Holder – $2.79
  • OLED 128×64 pixel I2C Display – $6.99
  • Alligator Clip Jumper Wires – $1.50 (estimate)
  • Miniature Solderless Breadboard – $3.26
  • ESP-01 Wi-Fi Modules – $2.60
  • Six LED Indicator Module – $1.10 (2 for $2.21 on aliexpress.com)
  • Passive Piezo Buzzer – $1 (estimate)
  • AMS1117 3.3V Regulator Module – $1 (estimate)
  • Header Pins – $1 (estimate)
  • DuPont Jumpers – $1 (estimate)
  • Micro USB Cable – $5
  • Micro USB Breakout Module – $1.84
  • Exclusive Micro:Bit Decal – $1 (estimate)

Several of these items are extremely cheap and only sold in multiples so I gave generous estimates. Total comes to $53.45. Things in that $3-7 range really add up quickly. Still a good value for the $44 subscription.
