My soldering is improving. This is a DSO 138 Oscilloscope that I assembled from a provided combination of discrete parts. The purveyors only ensured two required SMD* chips were factory-attached. At the US$22 entry price, including the housing, it was a fun and affordable project. If you take one of these on as a project, … Continue reading Getting a bit more challenging…
The latest assembly from Casa de Juan; A zap-o-matic? A high-precision random-number generator? A molecular stun-gun? a 50-Ohm dummy load for testing transmitters up to 20w output to minimize the risk of transmitting a signal; and burning up a transmitter while not hooked up to an antenna It's effectively a sandwitch of small PCBs surrounding … Continue reading What in the hell could it possibly be???
Whenever I see wordy output or excessive logging data, I'm reminded of that old joke about a Microsoft Engineer vs. a pilot. It's thorough, complete, and technically accurate... but completely useless. Found originally back in the early 1990s, reworked/reworded over time, pasted here for posterity, and because I don't want to go following dead links … Continue reading Technically correct…
The transceiver is fitted to the Altoids tin, and there's sufficient space to include a battery as well. I'll need to fit the removable jack for the antenna, and wiring harness for the battery, but I think it's turned out rather well so far.
My head [is] so full of things to say or share or do... but sometimes, before they get out, I forget. So I take notes. Lots of notes. Sometimes actually writing things down. Ideas, thoughts, stories, plans, sketches, pictures -- our current technology helps me maintain focus.
Apart from an astoundingly simple audio alarm and several car stereo installs, I've never built any actual electronic devices. So I'm actually rather impressed that I managed to cobble together a Pixie_4.1 from parts and with only a schematic and some rather worthless Chinese-language only instructions: It even works, as well. I'm sure nobody was … Continue reading It’s Working!
So this just rolled in on the heels of yesterday's remarks about delivery issues. No. No, they didn't make the attempt at all. In fact, I'm reasonably certain they weren't even in the neighborhood at all.
