3D printed battery cover for Hewlett-Packard 100LX/200LX

One of the most typical hardware failure of HP 100lx/200lx is a broken battery cover latch. That’s why a spare 3D printed battery cover would be a good option even if your current battery cover is intact. A free 3D model of the battery cover is available on Thingiverse. However, I was not satisfied with the quality of this model, therefore I’m glad to present you a custom (improved) version.

CPU replacement in Sony VAIO UX

Sony VAIO UX is one of the most outstanding, elegant, and powerful UMPC of the first epoch. Despite the quite wide range of models in the UX series and quite high prices, there were no dual-core versions of the device. However, the device itself is 100% ready to work with a dual-core processor. Therefore it’s relatively easy to make a custom upgrade.

The gallery below represents the process of CPU replacement: the original Intel® Core™ Solo U1500 is replaced by Intel® Core™2 Duo U7700 (dual-core, 64-bit). The modding was made by a professional master Sergey (aka Freeqwer). Here is a video from Sergey of a similar modding made for another item: https://youtu.be/OcuwCzd7C0I.

According to my benchmarks, Core™2 Duo U7700 is actually two times faster than Core™ Solo U1500 when the application utilizes both cores. The new CPU has increased the power consumption of the device by 25% and the cooling system is able to handle the extra power without the device overheating.

MutantC V3 – DIY handheld computer

mutantC_V3 is an open source handhled. The schematics and 3D models are free (MIT licenced). The device is based on Raspberry Pi and Arduino boards. It’s an open platform: there is an expansion port for adding additional features like GPS or Radio.
The design of the handheld seems to be inspired by Sony UX. It includes hardware keyboard and sliding display with touchscreen.

Recovering antenna covers of OQO Model 01

The case of OQO Model 01 is made of metal, it’s quite sturdy. However, the antenna covers are made of transparent plastic, which is prone to cracking.

In order to recover the cracked antenna covers I made a 3D model of the original antenna cover (antenna_cover.stl) and printed it on a photopolymer printer. I didn’t like the result, because the wall covering the antenna was too thin and fragile. So I decided to thicken the wall and sightly modified the original model.
