How To Overclock A Casio Fx-9750G Plus

August 1, 2007 by 13 Comments


[Visceroid] could only find overclocking resources online for TI calcs. He spent some time under the hood of his casio fx-9750G plus and sent in a write-up for us. I gave it a quick edit, but here it goes:

I opened up the calculator, which reveals the board with the processor on it,
with the RAM, ROM, CPU and a few other surface mounts visible.
The graphics are underneath and the buttons are also underneath on an underlying board.
The main batteries, backup battery and serial port are connected on the underlying board, and I also have access to them.

SIP For The SMC WSKP100

July 31, 2007 by 2 Comments


[sprite_tm] made my morning by sending in his latest work. After opening up his new SMC WSKP100 (Skype wifi phone) to identify the hardware differences, he managed to shrink a flash image from the SMCWSP100 to fit on his new toy. Then he spent some time hacking the kernel from the former to work on his phone. The result? A SIP operational phone that’ll connect to his asterix server at half the price of SMC’s official SIP phone.

Switchmode Power Supply Hacking (power Your Laser)

July 27, 2007 by 7 Comments


[Mike] wanted a better power supply for his argon laser, so he modded some switchmode power supplies. With a few tweaks, he had a few adjustable voltage outputs and a nice solid supply of electrons for his laser projects. If you need a lab quality adjustable power supply for your projects, this is a nice way to get it on the cheap. (He’s in the UK, but the same ideas should apply to us models.

Mecha Turbo Crazy Coffee Roaster

July 26, 2007 by 20 Comments


I’m a wee bit of a coffee geek. This roaster was built by [farmroast]. It’s a highly modified of version of the roaster that I’ve been using for the last year or so. A convection oven up top provides the primary heat source, while the beans are spun around in the roast chamber below. A pair of thermocouples let you know what’s going on inside the chamber. When the roast is done, pop the top, dump the beans into the drawer, and a fan mounted below cools them to room temperature in about a minute. It was put up for a home roaster building contest – You might be interested in the other entries.

I hope the coffee wars at defcon are this interesting.

[BlueMoon] let me know about a translation of an interview posted over at xbox-scene. The original dutch version is here. It’s a very good overview of XBox 360 security and the exploits needed to take advantage of the hardware.

If you dig EVs, you might want to check out my latest experiment. I’ll be building a EV, but each step of the process will be defined by reader votes. It’s $1/vote, with the idea that the votes will pay for the project.
[Jay] sent in a little info on streaming audio and sometimes video to your Wii.

[Robert] sent in his research on building and testing diy GSM antennas for extending rage range.
