每周一次，我们从提示框和读者评论中收集一些优秀的读者提示，并与大家分享。本周我们将研究一种在Windows下控制Xbox控制器的替代方法，如何让你的电脑在酷暑中保持凉爽，以及如何构建一个强大的DIY图书扫描仪。

用joy2key控制xbox控制器

Srivatsan在《如何在Windows PC上使用Xbox 360控制器指南》的评论中分享了以下技巧：

For a free alternative, I recommend Joy2Key. Its a bit less user-friendly, but you can generally do everything that Xpadder can do. And you can also make several “profiles” for each program you use, like for each emulator, for example. Just a protip.

这当然是一个可行的选择，以10美元的价格标签上的Xpadder（虽然我们是这么大的球迷Xpadder和一般质量和用户友好的应用程序，我们很高兴支持一个人的商店背后）。谢谢分享！

保持电脑清洁以降低工作温度

使用以下提示标记“提示”框中的内容：

I’m not sure if this is as much a tip as it is a reminder given that I’m just going to tell everyone to go read the same HTG articles that I read… BUT I can’t say enough good things about your computer cleaning tips. I live in a third floor apartment with no AC and it’s so freaking hot out where I live. I’ve been doing everything I can think of to keep my computers cooler but by far the best (and way less fussy than messing your chip speed and voltage, for sure) is just making sure the case is really clean. I followed your overheating laptop/cleaning guide and and your clean a dirty desktop guide. After cleaning both my laptop and desktop the average operating temperature on my laptop dropped a full 8F and on my desktop a full 4F. That’s a serious shift for what amounted to very little work.

我们不能说我们很惊讶！多年来，我们已经解决了多台台式机的过热问题，方法是将硬件上1/2英寸的防尘绝缘层炸开。一台干净的电脑是一台快乐的、更好冷却的电脑。

做一个diy书籍扫描器

Uri在这个DIY图书扫描项目中写道：

I’ve really gotten into ebooks lately but there are so many books out that there are never going to get turned into ebooks. Sure you can get popular fiction and best sellers, but what if you want to read a book from the 1950s on your reader? Unless it’s been a best seller ever since then, it’s not happening. To that end I started building a one of the DIY book scanners I found via Instructables (turns out I was using one the best known builds around and they have their own web site now). Other than a few special parts, it really is something you can build out of scraps. I’m almost done with mine and so far, during the initial tests, I’m surprisingly fast at manually scanning the books given how easy it is to switch from page to page and get a perfect shot. I figure a few more tweaks and I’ll be able to scan books while watching movies.

我们已经有一个这样的书籍扫描仪在我们未来的DIY项目清单很长时间了，这可能会推动我们开始工作。谢谢你，乌里！
