Today I received a pleasant surprise in my inbox: That’s a bit more than $8 at the current exchange rate. I didn’t know that someone (or multiple someones) was already using the Brave browser and allocating Basic Attention Tokens to me, so that was a really awesome surprise for me today. Thank you very kindly… Read More Many Thanks
As you have probably seen, I’ve launched occasional Twitch streaming of my work activities, including schematic capture, PCB layout, library coding, firmware coding, and even some solder melting. It’s been a bit of a learning curve, but I’ve been traversing it fairly successfully, I think. However, one big problem that I was having was with… Read More A New and Improved Experience
A brief update to let you know how things are going. I’ve got a long checklist of things to implement in the OpenBeacon Mini firmware, and much of it I can leverage from my old OpenBeacon 2 firmware (although quite a bit of that needs to be refactored and updated). However, one bit that I… Read More OpenBeacon Mini Firmware Coding Proceeds
I had one footprint error, but otherwise it seems to be working as expected. About 300 mW RF output. More details to follow.
…receiving a shipment of PCBs from Shenzhen.
Since I’m waiting for circuit boards for OpenBeacon Mini to arrive, I want to keep the waiting time as productive as possible, so I’ve been working on the firmware. Specifically, one of my recent goals was to factor all of the modulation code out of the spaghetti mess that is the current state of the… Read More A New Arduino Library Appears!
If you watched my previous Twitch stream, you may have seen that I completed the layout of the first PCB spin of OpenBeacon Mini. Today I ordered the PCBs from DirtyPCBs, along with boards for my low-pass filter module, and more Empyrean boards in anticipation of wider beta testing soon. I wanted to get these… Read More OpenBeacon Mini Proto PCBs On The Way
Arduino – Si5351 Powered Signal Generator Please enjoy this write-up of a nifty, compact signal generator project using the Etherkit Si5351A Breakout Board driven by a Teensy LC. What I really love about it is that it uses an 18650 LiPo cell with a small USB charge controller, so that it is very portable. Neat stuff!
I managed to finish the layout of the OpenBeacon Mini prototype PCB in KiCad this evening while livestreaming on Twitch. A 3D rendering from KiCad is above. It looks about how I sketched it out and wasn’t too nasty to route, so I got that going for me. So I’ll get on order off to… Read More OpenBeacon Mini Proto PCB Layout Complete
