I recently purchased this Commodore 64 on eBay in a bit of Retro nostalgia. Bring on the C= hacking!
This is a 4-cell battery; before opening it up, I was under the impression that it was a 3-cell.
The charge controller circuit board has “LIP8198” and “1-867-277-11” markings in the silkscreen, along with a strip of Kapton tape over the top of the PCB.
The PCB has +/- going to the 4 cells in series, as well as leads between each cell (probably for measuring voltage at each intermediate point), and two temp sensors: one on the battery closest to the circuit board (the one that the board’s “-” connects to) and one on the next one after that (the middle-most one).
The top side has the following ICs:
The bottom has the following:
With a bit of digging, it seems that the bq80201 is used for many different battery makes such as Sanyo, Dell, etc.

Would still be nice to actually find a listing of the I2C codes that it uses.
I found 3 or 4 of these at a garage sale a few years ago for a few bucks, and I am (surprisingly) just cracking them open now.
On the front, it is marked as D-Link DWL-120 11Mbps Wireless USB Adapter, on the back is FCC ID# MXF-WL280, H/W: B2, F/W: 2.25
On the bottom of the PCB, we have the following chips:
On the top of the PCB (under the RF shield), we have the following chips:
I plugged it into my i386-based laptop (My x64 desktop doesn’t have drivers) and got this dmesg:

This is a nice item that I found today at Princess Auto… A grey box hiding on the bottom of a grey shelf. The phrase “Demo Kit” caught my eye, and I had to take a peek inside. I was blown away by the beautiful innards, and I just had to have it. It appears to be made by Flambeau (judging from the company name stamped into the front of the case) and the sticker on the lid says it is a “Brake Control Demonstration Kit”
A metal front panel (as seen in the picture) holds a set of terminals, a voltmeter, large Brake and Overload buttons along with various assisting components, such as Output and Stop lights, Battery test button, power switch, 30A removable fuse, and a panel-mount power plug that fits with the included wallwart.
Underneath the panel (picture attached below), reside a 12 Volt, 5 Amp-Hour SLA (Sealed Lead Acid) battery for powering the kit, and some type of coil or capacitor for powering the ‘overload’ button.
Bonus points for the Output and Stop Light lamps: They’re actually incandescent bulbs, not LEDs. (The power light is an LED though, presumably so you can still see that the unit is not DOA even with a near-flat battery.)
Possible uses: (besides requisite attempts to blow various electrical components up with the Overload button)
(NB, this doesn’t show up on Princess Auto’s website, as it’s probably a new item. It is SKU #8339715 and

Prep:
I just got my shipment of stuff from BGMicro, including a ton of pinheaders!
I ordered:
1x Velleman 4×4 keypad
1x GI AY-3-8910 Sound Chip (and matching IC socket)
2x LEDs with wire and
connectors
1x 2.5″ stero cable end (Digital Rebel XT Trigger?)
1x Graphical KS0108 Display
and Lots of 1×40 and 2×17 Pinheaders ๐
I recently acquired an old Photoco MiBook. (Photoco LLC had its assets sold off by creditors, and many MiBooks and associated software are being sold on clearance by stores like The Source by Circuit City). Photoco LLC magically reopened under the name of MiBook LLC, and is currently the subject of a nice big lawsuit from Scripps Networks, the owners of Food Network, etc. It’s an interesting read.
My first of two MiBook readers that I’ll be looking at is this one, which I got from The Source by Circuit City in a “Home Decorating and Gardening” bundle for $29.96, and a set of “books” on 512MB SD
cards for $1.96 each.
The sticker on the back reads “miBook”, along with voltage/amperage requirements, Serial Number (no barcode) and the FCC logo.
I also have another MiBook reader which I got as a prize from DigiKey. It came as just the MiBook/charger/USB/Remote combination, and didn’t have any SD-card “books” like the Source’s bundle. This one is a little newer, and is better-built overall: the stand snaps into place, the charging LED is more visible, the buttons are better quality inside, the plastic pieces are formed better, the exterior screws are larger and much easier to remove, etc.
The sticker on the back reads “PHOTOCO miBook”, along with voltage/amperage, Serial Number with Barcode and the FCC logo. (It is interesting to note that this one is labelled specifically a PHOTOCO product. Old stock that they brought over from Photoco LLC to Mibook LLC? Check out the link at the beginning of the article for information on Photoco/Mibook/etc.)
Nyko “Kรคmรค” Wired Remote:
MCU: Atmel ATMega 48 TQFP (The PCB also has pads for MLF package, based on availability?)
Accelerometer: Freescale A7260
EEPROM: Macronix (MXIC) MX25L4005 (4 Mbit)
Definitely a good nunchuck for hacking; it’s well-built, and the analog stick appears to be mostly metal-based, instead of plastic like others.
I wonder if the ATMega is read-locked? If so, I wonder how hard it would be to rewrite/repurpose it…
Biogenik OG1-CHUK:
The only thing of interest was a single epoxy blob on the PCB.
Madcatz Z-CHUK Wireless: (FCCID: P25S1MC5746U1709C, 2.405-2.475Ghz)
MCU: Epoxy blob of unknown origin
Accelerometer: Unknown. “033 A841 013”?
EEPROM: STMicroelectronics M24C02 (2 Kbit)
Wireless is nice, and might make for some interesting projects, and at $10/piece from XSCargo, it’s definitely an affordable way to get into wireless (and accelerometers, etc). The internals of this remote look almost identical to the actual Wii Nunchuck, with the exception of the battery and transmitter.

This is my new Freeduino, which I purchased as a kit from the fine folks at the AlphaOne Hackerspace table at QuahogCon 2010.
I assembled the kit together at the Hardware Hacking Lounge with some super-sweet soldering irons, then spent the next hour and a half trying to figure out why it wouldn’t work. Turns out that it needed a jumper on the USB/External power selector. Thanks to Mr. Jimmie Rodgers for the eagle-eye lack-of-jumper spotting.
I already have an Arduino (the original); however, it doesn’t have a pin for the reset line or 3.3V line on the headers, so I guess it will just be relegated to different tasks.
I had planned to submit an entry into the Alpha One Labs Hackerspace’s Arduino Hacking Contest, though I ended up spending every waking moment trying to hack the Humans vs Zombies game. Apparently, I was not the only one with not enough time; there were unfortunately no entries into the contest ๐ I ended up receiving honorable mention (consisting of a T-shirt) for constructing my Freeduino.
Hopefully, there will be an Arduino Hacking contest next year… Start building those Arduino projects!
What I Did:
I took a Cellboost IPR3 that was otherwise destined for a dull life of providing power to an original iPod Shuffle, and converted the cable normally used for charging it into a USB-A-to-2-pin cable using the cable from an old computer case’s hard drive activity light. (Using the cable is a bonus for me, since this cable has been kicking around the
What I Wanted to Do:
I’ll be the first to admit this isn’t so much a ‘hack’ since it’s what the badge was designed to do. I had planned to populate the two 2×16 rows of headers with female headers, then put a piece of perfboard on top either with male headers pointed down or with female headers with double-length legs. The plan was to have something akin to an Arduino shield: Removable, changeable, and replaceable. What you see here is what I got done during the ‘con. I’ll post updates as I progress in badge-hacking now that the ‘con’s over.
About the Cellboost IPR3 Hardware
The Cellboost device contains 1 Li-Ion battery, 5V charging circuitry, and 5V output circuitry; the charging circuitry is the best part, since Li-Ions are a pain to charge otherwise. It includes a USB extension cable (USB-A Male to USB-A Female) that supplies power only (no wires for data) to charge the Cellboost unit with. The unit itself has a USB-A Male (for charging the Li-Ion) and a USB-A Female receptacle on it (for the iPod to plug into).
I acquired a number of these Cellboost devices from Princess Auto; at their last big clearance sale, they were on for (IIRC) $0.79 each. As an aside, I had someone at Quahogcon ask me if I had been to the MIT Garage Sale. Apparently they were sold there as well. Regardless, I still have 4 or 5 in their original packaging to be used to power other projects.
