iPhone 6 Over Temperature after Replacing Battery

I just replaced the battery in my iPhone 6. When I attempted to power it up with the new battery, I was greeted with this ominous screen: which is strange, because there’s no way that it was too hot, since it was just booting up, and it wasn’t even warm in the room where I […]

Mini Review: Linksys WRT1900AC

It infuriates me how so many WiFi routers are designed with inadequate cooling. I have a whole pile of routers that got flaky or crapped out after a few years due to overheating. The only ones that are still rock solid after years of continuous service are my WRT54Gs. My Linksys E4200 has been getting long […]

Test & Review: GOPHERT CPS-3205 0-30V/0-5A Bench Power Supply recently had a special on the Gopher Technology CPS-3205 bench power supply. After searching for reviews, which were generally favorable, I decided to get one for $42.99 including shipping. At this low price, I figured it was worthwhile if it worked at all. The unit is small, fanless, and appears well-constructed. What convinced me […]

Maple Mini – Serial Programming and Upgrading to Bootloader 2.0

My BAITE BTE14-07 Maple Mini clone came with LeafLabs’ original bootloader. I decided to upgrade to Bootloader 2.0 in order to free up some RAM, and take advantage of some of the new features. UPDATE: Roger Clark, the STM32DUINO guru, posted a comment below, informing me that you can upload to Bootloader 2.0 by simply loading […]

First Look: BAITE Maple Mini Clone

Recently, I’ve been searching around for inexpensive higher powered alternatives to AVR-based Arduinos. There are several ARM MCU’s available that give a lot more bang for the buck in terms of RAM, speed, flash, and I/O. While I like PJRC’s Freescale-based Teensy 3.x boards a lot, they’re only available from a single source, and use a […]

SkyRC iMAX B6 80W (FAKE) Battery Charger

After reading about the SkyRC iMax B6 Charger on rcgroups, I decided to buy one. I chose a US-based seller, globalexcellent_ltd on eBay, and paid $17.99. The listing claimed that had a max charge power of 50W, and due to the low price, I figured I was getting a clone. I didn’t mind if it was […]

Installing English Firmware on a FAST FWR171

I recently learned that the FAST FWR171-3G is a lower cost clone of the TP-Link TL-WR703N, the only difference being the case. While browsing AliExpress, I found what I thought was a great deal… the FAST FWR171 for only $16. After waiting over a month to receive it, I noticed that it doesn’t have a USB port. […]

Quickie Hack: Turn Your Bicycle Into A Party Machine

I was looking for a way to play tunes while biking the other day, and was too lazy to get out the CAD program and design something to print on my RepRap. Here’s a dirt cheap & quick hack to get some decent quality sound while riding your bike. All you need is 4 zip ties: […]

TL-WR703N: Attaching USB Serial Adapters – FTDI/CP2102/PL2303/CH340G

Although the TL-WR703N has a built in UART, as I have shown in my previous article, it’s rather difficult to access, and is useful as a serial console in OpenWrt. For the support of your own apps, it is far more convenient to simply plug in a cheap USB to serial adapter — this can be […]

RepRap: Printrboard Surgery

After a hiatus of a couple of years, I’m finally starting to get back into 3D printing. One of my Printrboards got messed up when some wires on my hot end shorted. The hot end temperature was no longer reading correctly. Since my other Printrboards all work correctly, I knew that the problem was not […]
