Why You Shouldn't Leave Your MakerBot Running Overnight When Using a Weak PC

A big blob of PLA on the build platform

Yup. It ran until it had run out of plastic. When I looked at the computer, the screen was flashing random patterns. Yeah, it was that bad.

Then, this happened:

Whoops

AND THIS IS WHY YOU MUST NEVER EVER FOREVER NEVER EVER EVER NEVER RUN YOUR MAKERBOT/REPRAP OVERNIGHT!

But I know you'll do it anyways. ;D

Domain name change!

Woohoo! I successfully switched the domain name from cyrozap.blogdns.com (DynDNS) to cyrozap.com! I got a really good deal with 1and1.com ($8.99/year or something like that with the first year free—that's $.25 per month), and if you click on an individual post, you'll see that below the "Submit" button for comments, I switched the ad from Amazon to 1and1.com's affiliate program ad.

Well, now I can have subdomains, like store.cyrozap.com!

I also got the DynDNS name to redirect to the new domain name, so all the old links work.

Selling Mendel and Mendel Mini Parts Individually or as Half-Sets

I posted this on the RepRap Forum here.

If you don't want to follow the link, you can read what I wrote here:

I printed half a set of Mendel Parts, and because it's been difficult for me to finish them, I'll be selling them either individually or as a set.

The half set includes 14 build plates (I'm pretty sure) of this set of parts. Here are some pictures of the parts (click the images to see them full size):

I also have a less than half-completed set of Mendel Mini parts that is also for sale.

Please contact me at cyrozap AT gmail DOT com if you're interested, and please specify whether you're interested in a few parts or the entire half set. This is not a commitment to buy, I'm just using this to gage interest.
Happy Making!

Parallax serial RFID reader for sale (again)(again)!

It didn't sell the first or second time I listed it, so I'm now selling it starting at $9.99 + $4.90 shipping to the continental U.S. only. It's a good deal as it originally was over $40.

I bought two of them cheap and I'm selling one here. It's a 125 kHz reader that comes with 2 tags. It outputs the tag ID on a 5V TTL serial line at 2400 baud. It's perfect for projects that require contact-less identification, like an RFID-unlocked door.

Fixed HP LCD Monitor

On Sunday, I repaired an HP LCD screen. For some reason, it wasn't powering on, so I looked online for solutions to power supply troubles in LCDs. Eventually, I came across an Instructable to fix this very problem! It was for a slightly different model (the vs19e, I have the vs19d), but it helped me get the case off and, after seeing the three popped capacitors and replacing them with capacitors from an old-ish conference desk phone and a capacitor from Parallax's "What's a Microcontroller" kit (all were 10V 1000uF), I had a working monitor again. Well, that was a really free fix, and I'm glad I didn't have to buy anything from Radioshack as I usually do. I've nothing against Radioshack, I just think they're a tad over-priced for a lot of what they're selling, even though they add convenience.

Mendel Mini Parts to be Made and Sold!

Currently, my MakerBot is producing the parts needed to build a Mendel Mini. I will not be making them for myself—these will be sold on ebay. I'll be posting a link here and on the RepRap forums when they're available. These parts will cost about half as much as a set of Mendel full-size parts at around $250.
