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. The procedure looks pretty straightforward, but I ran into some snags. Perhaps the easiest way to change the bootloader in a Maple […]

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 […]

Pyle PSWGP405BK GPS Watch Software and Firmware Updates

Today, I discovered that the New Balance NX990 GPS Cardio Trainer Watch, like the Pyle PSWGP405BK, is just another Latitude Limited Nav Master II clone.  Following my hunch, I searched for the NX990’s accompanying software, and lo and behold, it’s just rebranded version of GPS Master! Best of all, it’s an updated version, v2.0.16.124, vs […]

GPX and TCX output from GPS Master Software

A couple of years ago, I bought a Pyle PSWGP405BK GPS watch with Heart Rate Monitor. It’s been a great device, though it’s big, and a bit ugly. The battery far outlasts my wife’s Garmin watches, and I love the customizable screens. My main problem has been the lack of a useful way to extract heart rate […]

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. […]

How to Repair a Panasonic Massage Chair, Part 3

Unfortunately, my rubber hose hack from Part 2 worked only for a few weeks. The belt again stretched, and became loose: One thing you can also see in the photo above is that I’ve slid the motor as far to the left as the adjusters allow (the slotted holes for the two brass screws). I couldn’t […]

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: […]

OpenWrt: Cross-compiling libmicrohttpd for TL-WR703N

Recently, I’ve been developing embedded webapps using node.js. Unfortunately, node.js is a bit bloated for resource-constrained platforms, such as the TL-WR703N running OpenWrt. Not only is it too large to fit into flash memory, requiring an external USB drive to run EXTROOT, but I’ve even encountered circumstances where I’ve been running out of RAM. Thus, […]
