Since implementing HSTS and an HTTPS redirect properly was trickier than I'd imagined, I decided to write my own guide on how to do it. I'll also explain how to configure Nginx to use OSCP Stapling and IPv6 since I worked on getting both of them working at around the same time as I got the proper HTTPS redirect working.

While the pricing for Cloud Files was very agreeable, you really did only...| Cyrozap's Tech Projects
Two factor authentication (2FA) is an amazing invention. For one thing, it can significantly increase the security of your online accounts without significantly increasing the hassle of logging in. Additionally, the most popular 2FA algorithms are available in both free software and proprietary software implementations. This weekend, I reverse engineered Symantec's proprietary 2FA token solution with the goal of creating a free software alternative. Motivation Why did I do this?

Approximately three years ago, I posted instructions on how to get an iPad data plan without having to own an iPad. Just for fun, I decided to check if that method still works and, well, it does!

After over a year of silence, I'm blogging again! A lot has happened in the time I've been away, the most notable of which is probably the new look of the website. As you can see, I've abandoned my self-hosted WordPress blog in favor of a static blog hosted on Rackspace's Cloud Files.

I just backed this project! Why? Because for $400, I get one of the most flexible and inexpensive SDR's on the market. Not only do I get that, I also get in-depth documentation and guides on how to use it. I've been wanting a nice SDR for some time now, ever since I saw the OpenBTS demo using the Ettus Research USRP1. Unfortunately, the USRP1 is, to me, too limited to justify the price. Additionally, there is a very steep learning curve if you're a beginner like me. I'm still interested in ce...| Cyrozap's Tech Projects

Hardware upgrade: After wiring the 8-pin CPU power connector to go to the relay board and connecting my Cupcake's new PSU, the machine no longer skips steps in the Z-axis nor in the extruder and the heated build platform and extruder nozzle heat up in a more timely manner.

I'm pretty sure this works because the CPU power is o...| Cyrozap's Tech Projects

This is the first post in my quest to get my Kyocera KR2 running some more modern firmware. For those of you who don't know, The CradlePoint MBR1000 3G/4G wireless router is essentially a rebranded Kyocera KR2 with different firmware and no PCMCIA slot. Internally, the hardware is exactly the same (except for the PCMCIA card slot).

After 3 years of faithfully supplying power to my MakerBot Cupcake, the power supply has finally died. Every time I switched it on, it would turn right off.

A week ago, I bought three 3' lengths of 8mm smooth rod for my Prusa Mendel because I wanted to use LM8UU bearings. After receiving the rod and cutting it, I've fond that they make a huge difference in reducing play between the linear bearings and the rods. With 5/16" rod, you could feel the bearings wiggle. Now there is no wiggle at all! If you're building a "United States customary units" Prusa Mendel and are ordering online and might use LM8UU bearings now or in the future, get 8mm rods.

I've also now listed my refurbished & unlocked Blackberry on ebay ($150 + shipping), though the ebay fees are really high, so I'd prefer it if you'd buy it on SellSimply. In fact, I've dropped the price on the SellSimply one to $130 with Free USPS Priority Mail Flat-rate shipping (I only ship free to the US, though). I'll be selling some CRT monitors soon (one of them is a 21" one with...| Cyrozap's Tech Projects

Two weeks ago, on Wednesday, there was the "Future of MakerBot" meeting. It was fun, I got to meet some other operators, and we all got to provide our input into the future of the MakerBot. Essentially, we toured around MBI, went through some introductions, and talked about what we wanted and didn't want in the future for MakerBots. To all those that were there, I'm sorry I talked so much! I can go on and on about things sometimes... Here are some pictures:| Cyrozap's Tech Projects
Well, I kinda want to buy a more portable Mac (an older 17" MacBook Pro), so I'm going to be selling this for $400. Why $400? Well, I actually built it for just over $300 and similar Macs are over that price. It's really great at running a MakerBot, and it's good for iPhone development, too. Specs: 2.0 GHz Intel Core Duo Processor 2 GB of DDR2 667 MHz RAM Bluetooth Wireless N networking 100 GB 7200 RPM SATA HDD 2 USB ports 1 Firewire 400 port 1 Mini-DVI port Mic In and Audio Out ports 10/100 ...| Cyrozap's Tech Projects
Well, you can see/buy it at SellSimp.ly/9f. More pictures of it and the blackberry innards to follow.| Cyrozap's Tech Projects
I just saw this and I'm really jealous. I wish I worked for MakerBot so I could be "posterized" by Bre! I'm no artist and I really need a good logo (the current one is just "meh"). At least I live a 5 minute walk and a train ride away from Brooklyn (as opposed to living in California)! This reminds me that I should visit the BotCave some time. Eventually. If Bre says it's ok.| Cyrozap's Tech Projects
Well, I recently unlocked a Blackberry that's a bit beat up and once I get the replacement housing for it I'll fix it up and sell it. It's a black Blackberry Curve 8320, permanently unlocked. I have no use for it as I'm on Verizon and it needs a valid SIM card inserted for it to allow apps to use data features (even on WiFi). So, if you're looking to upgrade your GSM phone, I'll probably be selling this for around $125-$150. No, I won't ship international because it's prohibitively expensive....| Cyrozap's Tech Projects
I just thought of an amazing alternative to the RepRap motherboard that doesn't need a computer to drive it: the BeagleBoard! This way, you could have it interpret the G-code directly and quickly (as opposed to MakerBot's way of doing that work on the computer and then sending different, simpler commands over the serial lines, keeping the heavy-lifting off of the µController). In my hypothetical setup, the stepper drivers would be run directly from the computer, like how most CNC machines ar...| Cyrozap's Tech Projects
Here they are: Also, to all those curious, I will be at Maker Faire NYC, but I will not be exhibiting there. There is a chance that I'll bring my MakerBot, but it's slim.| Cyrozap's Tech Projects
Just so you know, I'll be exhibiting at Maker Faire RI in Providence on Saturday, so if you're in the area, I'll be at the tabe with the DIY-intosh, the Eee PC 1000HE, and the MakerBot. Why am I bringing my DIY-intosh? Well, because it's just so much more impressive in person. That and the fact that its 2GHz Core Duo leaves my netbook's 1.66GHz Atom in the dust when it comes to Skeinforging something.| Cyrozap's Tech Projects

As you may or may not know, my birthday was on the 16th (I feel like everyone is blogging about their August birthdays and what they got now—MakerBlock, Spacexula). Because few in my family actually understand what I do, they all just give me money. So, with those birthday funds, I bought myself a Sapphire 100282-TXSR, a Vapor-X ATI Radeon HD 5850 Toxic Edition graphics card that performs as good as, if not better than, an HD 5870. This is the first $340 step I've taken in my $1200 quest to...| Cyrozap's Tech Projects
Well, I did some testing, and I found out that the connector for the Core Duo MacBook keyboard connector is really just a USB port. Also, after pouring over a datasheet, I found that the two PSoC's on the keyboard's board are connected over an I2C bus and then the one labeled "B" is the one with the USB connection to the logic board. The one labeled "A" is the keyboard controller. With this newfound information, in theory, I could make that internal USB port external, giving my DIY-intosh an ...| Cyrozap's Tech Projects
I like to give my friends and family recommendations on products. I like to give them Amazon Affiliate links. The problem? Whenever I want to do that, there's an annoying process I have to go to to do that, and only I can use that process. If anyone wants to buy something and they want to credit me, they can't make affiliate links and have to ask me to make a link for them. So, to remedy this, I took 2 hours out of my day to make a PHP script that anyone can use to make Affiliate links from n...| Cyrozap's Tech Projects
Well, I just bought some new parts for my Makerbot. First, because my build platform broke, I bought the MakerBot Heated Build Platform Kit. I decided that, since I was switching back to ABS, I should be using a heated platform. I also didn't want to pay for a normal build platform now and pay for a heated build platform later when I'll really want it. Second, I bought the Magnetic Rotary Encoder PCB. I got 3 samples of the chip a while ago, so I just bought this because it may come in handy ...| Cyrozap's Tech Projects

Yay me! I downloaded the entire database as a .sql file, opened it up in gedit, did a Find/Replace for cyrozap.blogdns.com to cyrozap.com, restored the database with that file, and I was done! I'm sure I could have done a similar thing from the command line, but I don't know MySQL very well. Mission accomplished! ;D| Cyrozap's Tech Projects
