hyperkinetic

I picked up my donor bike a few months ago, and have been having a blast riding it. Now that it's getting hotter, I wouldn't mind having extra help getting place to place without becoming a sweaty mess.

I'm a bit confused by the mid-drive offerings at Lunacycle. Why is the Cyclone less money, even though it's higher power? Has anyone had problems with the plastic gears on the BBS02? How much over spec can you drive these things? I was originally going to get a 60V battery when I was considering a hub motor, but it looks like 52V is the largest available paired with the BSS02.

I'd love to hear experiences both pro and con for either u

Hi all,

I'm building a touch interface with multiple MPR121 using Bare Conductive's MPR121 library. My C++ skills are nowhere as good as my C, and I'm a little confused about how I go about creating multiple MPR121 objects that reference each sensor at it's appropriate address.

The library is supposed to be initialized before use by calling MPR121.begin(address). All the demo code only shows talking to one sensor, but I was expecting to create an object of type MPR121 for each address like this:

typedef MPR121 sensor1;
typedef MPR121 sensor2;
typedef MPR121 sensor3;
typedef MPR121 sensor4;

sensor1.begin(0x5A);
sensor2.begin(

Hi all, I've installed avahi on a raspberry pi installation and for whatever reason, I can resolve rpi.local from the pi itself and I can resolve all the other hosts in *.local on the network from the pi, but can not resolve the pi from any of the other hosts on the network. I've successfully installed avahi on Arch on a bananapi with no issues following the same recipe. The bpi is visible from every Ubuntu desktop and Mac on the network, and they to each other. For whatever reason, this lone instance doesn't seem to be publishing anything. Any suggestions?

[edited] for clarity.

[SOLVED!] I followed up on u/jaxxed suggestions with no luck, but it ultimately led me to new thing

Hi all. I've created a low res display (matrix) using WS2812B strips. So far my code takes whatever data I have in the frame buffer and sends it to the display at regular intervals. I've generated a few patterns within the Arduino, but the goal of this project was to play low res video files off an SD card. I have authored a series of videos for this display in Quicktime uncompressed 32-bit argb, in the display's 16x10 native resolution.

At first glance it appeared that this file format would give me direct access to the array of frames, but Quicktime is a complicated beast, and I'm beginning to think it might be easier to either pre-process these files to the bare minimum, or render them

Hi all. I'm trying to make a LED matrix display using the Arduino, which ideally reads the display data off an SD card. I've looked into a bunch of different file formats, and the closest thing to what I need appears to be Quicktime uncompressed 32-bit argb. It's raw RGB frame data, is readily supported by the authoring software I'm using, and allows me to output in the resolution of my display.

I looked into reading the .mov file directly, but it is a twisted mess of headers, structures, and metadata that is pretty useless to me. Processing has no problem opening and playing the video files I have. What I'm hoping to do next is extract the raw frame data and write it to a binary file to in

Hi all. I'm looking at upgrading our storage system. I'm running two Ubuntu servers, each with multiple Weibitech SCSI RAID (6) cabinets (these have performed like a champ!) totaling close to 48TB of scientific data. Both servers have a 4GB/s FC HBC connected to a Tandberg T40 LTO5 changer.

I would like to update the storage system to FC and ditch the SCSI cabinets. I'm looking for recommendations on the following:

• Best bang for the buck. EMC sounds great, but it's way out of my budget.

• RAID 6 is a must.

• Must keep the 'I' in RAID. Must have the ability to use commodity SATA hard drives. No pricy SAS drives.

• Ideally is available unpopulated, as I already have 80TB of disks at the

Here are the details:

• Need to monitor 10 ID-12 RFID modules in real time

• Baud rate is 9600bps

• Messages are short. 12 bytes total.

• No requirement for TX

The software serial driver warns that only one port can listen at a time, meaning it's possible that I may miss a message if two devices send at the same time.

The datasheet on these modules sucks. I had an idea that if the TX pin was either open collector, or went tri-state when in reset, I'd scan the reset pins in succession. I still haven't determined what type of output it is.

Please, if you don't have a firm answer, don't guess.

Would those of you who have placed your marker on the map please update your marker with the approximate height of the location where your node would be installed and state whether it's roof, balcony, or fire escape. In the case of the latter two, include the direction it faces. To roughly estimate height, multiply your ceiling height by the number of floors between the ground and the mounting point.

Once this data is collected, playaspec and I will create a topo map and begin plotting which nodes can see each other.

I understand the various technologies and methodologies used in fox hunting, but nearly everything I've read on Google is focused on VHF and UHF. Given the proliferation of part 15 devices in the upper ISM bands, why aren't there more > 1GHz hunts?

Looking to discuss the best equipment suitable for hunting wifi, bluetooth, and others.

e2fsprogs 1.41.14 would be a step up, but ideally, I'd like 1.42. Everything I've read so far says back porting a package from a newer distro is a nightmare because of dependencies (Primarily libc). I'd like to avoid breaking the package system, but if I have to remove the old one and build from source I will. Hopefully there is a better way?

<rant> I gotta say I'm rather annoyed that a distro *claiming* long term support is so laxidasical about keeping critical system tools up to date. 1.41.11 is known to be broken, and is currently biting me in the ass. </rant>

[EDIT] I pulled the newest version via git and built it against the existing libraries. Every volume that passed as

We recently bought into a co-op, and now the super is telling us we're not allowed up on the roof to install an antenna, yet I can see several lining the roof from my window!

I'm well aware of the FCC restriction rules on broadcast and digital services, and plan on sending the co-op the link with a formal request in the morning.

What have been your experiences?
