Cool New Heatsink Drops CPU Temps

In the process of building the kids’ new computer, I bought a new heatsink/fan for our P4 computer, along with a 320GB WD SE16 SATA hard drive. We were down to 1GB on the main drive, which amounts to 1% free space, which wasn’t enough to do anything, not even dump the latest set [...]

Troubleshooting the RAM Issues

Here’s the results after several hours of running Memtest86:
DIMMA1/RAM1 + DIMMA2/RAM2 = ERRORS, 8 Passes, 20,000+
DIMMA1/RAM1 + DIMMA2/Empty = ERRORS, 3 Passes, 4,000+
DIMMA1/Empty + DIMMA2/RAM1 = ERRORS, 4 Passes, 793+ (2.7V)
DIMMA1/RAM2 + DIMMA2/Empty = No Errors after 6 passes, 30 minutes
DIMMA1/Empty + DIMMA2/RAM2 [...]

The Upgrade Turns into a Brand New PC

Here’s the update on the PC upgrade: All the parts arrived on Thursday and everything arrived in great shape. The Biostar open-box was certainly just that, it didn’t come with anything other than the mobo in a static bag and the box. Which was fine, I’ve got a bunch of IDE/SATA cables [...]

Get Ready for 3S Li-po Power

I got an email from Mike over at cheapbatterypacks last night saying he was doing a huge blowout on all PolyQuest li-po battery packs, and once they were gone, they were gone for good. I’ve been wanting to get a 3S 11.1V pack for my Super Cub for a few weeks now, but haven’t [...]

Wordpress 2.1 Released

I upgraded to Wordpress 2.1 tonight and so far I like it a lot better. After loosing an entire post one night after hitting Publish only to have the server time out on dump everything I’d written into oblivion, I got into the habit of hitting ctrl A then C (select all and copy [...]

Upgrading an Old PC on the Cheap

My kids have an old Compaq Evo desktop computer we got them that they use mostly for playing games. Oddly enough, they do more “gaming” than I do, so it makes sense that they need a semi-modern computer in order to play all the cool games that are available for kids. Right now [...]

It’s a Snow Day

It doesn’t snow very often in this town, but when it does, it’s a magnificent site to see. The weather recorded 4″, although it looked more like 2″, it’s still more than I’ve ever seen since we’ve lived here. The kids loved playing and running around in the white powder all over the [...]

Speed 480 BB Race is a Bust

I did a static run of the new motor with the new ESC and within 3 minutes of running the motor began smoking and the RPM’s began to drastically drop. Another minute or so later and the battery was dead. It went through a newly charged pack in under 5 minutes and by [...]

Fixed the ESC with a 260A FET

My parts from Digikey arrived yesterday (after only 2 days) so last night I spent an hour soldering up everything into the receiver unit and it works great! Of the 5 FETs I bought, I tried out the IRL3713 FET first and didn’t have any problems fitting it in (other than my usual sucky [...]

The Inner Workings Hobbyzone’s ESC Unit

Since I fried the speed controller portion of the receiver module on my Super Cub, I figured I would see if I could fix it first before I just buy a whole new unit. There’s a single TO-220 package FET on the board which is marked with the numbers 07N03L. Doing a Google [...]
