Tampermonkey, the successor to Greasemonkey, allows on-the-fly modifications to webpages. Things like adding buttons, or modifying text on a page. Facebook Marketplace is fast becoming the only viable used item listing in my area. Which is annoying – It’s inferior to Craigslist in any way, but the latter is clearly dying a slow death.… Read More: Adding a hide button to Facebook Marketplace with Tampermonkey »
Instead of a TV at home, I use a projector. It’s on my ceiling, with the buttons inaccessible. The remote for it also isn’t really working anymore. Problem. There’s nothing on the remote control’s PCB except for an obscure microcontroller (TTR013), IR LED and driving transistors, and some carbon contacts for the buttons. The intermittent… Read More: Very Remote Control »
I’m on a home improvement kick. When I walking my home, there’s a long, featureless hallway with kitchen at the end of it. I was using a tray on my kitchen counter to toss keys onto when I walked in the door. This takes up valuable kitchen counterspace, and being at the end of the… Read More: Key Storage »
I’ve used a lot of solder paste, usually from one of those big syringes. When depositing little tiny blobs of solder on a few hundred little tiny pads, two problems emerge: That big syringe has a big plunger that really starts to hurt the heel of your hand after a lot of usage, especially when… Read More: Syringe Full of Lead »
I haven’t actually made an Internet of Things, thing, before now. This is mostly just to throw some stuff together that I already had lying around. I’ve got a DHT11 temperature/humidity sensor, a WeMos D1 Mini ESP8266 dev board, a switch-mode power supply module, and a solar panel. I turned it into an investigation on… Read More: I Made An IoT »
Shallow As a test, I designed a nautilus-themed PCB in PCBmodE. PCBmodE is not your standard ECAD package. It’s a collection of JSON files that get converted into SVG or gerber files. There are some limited tools to convert SVG files back into JSON, too. It can be thought of as forward- and back-annotation.… Read More: PCBs of Unusual Style »
Here’s a quick one. I’m tired of having to solder programming headers onto projects that don’t need them after initial development. So I bought a bag of clothespins for a couple bucks from China and went wild with some epoxy and Pogo pins. Soldering made the epoxy fail faster than I expected, so… Read More: Clipping the Leads »
I’ve posted here before about my troubles with flexible flat connectors. Well, not directly, but that always seems to be a tangential obstacle in the already perilous minefield of hardware hacking. Basically, I hate them and I want them to go away. The answer is, obviously, a breakout board, but I was having trouble finding… Read More: FFChkMate »
At a place that I hang out on very rare occasions, there’s a big red button. When somebody holds it, it starts up an air raid siren that can get really loud. Unfortunately, it spins up very slowly, so people let off as soon as they figure out what the button does. That results in one… Read More: I like candy. Do you like candy? »
Preface: This is a year-old post that I never published. I guess I was waiting to be able to snap some pictures, but that never happened. Most of these components have been e-wasted by now. — I’ve talked about various avenues of rapid prototyping circuit boards before, and not really come up with any definitive… Read More: Stop-gap PCB creation (has stopped) »
