What am I up to right now? I like [Derek Sivers's idea about answering this question](https://nownownow.com/about) in a "now page" -- sort of, what you'd write in a holiday card, but without actually having to send holiday cards. So I hope to keep this page up to date with, approximately, what I've been doing over the past 6-12 months, and what I anticipate my focus for the next 6-12 months will be. I think it's more fun to have this in bullet form. Whenever the date is up top is when I lasted updated this. Also, when I was very young, it was impossible to get me to do anything in a timely fashion. (It still is, but it's my problem now.) My mom, reportedly, used to say "Joshua, _now_!", to the degree that the neighbors thought it to be a funny nickname! I think as a teenager, I was presumably mortified about this (like everything in one's life as a teenager), but obviously it is just much funnier to accept it. Below, you will find Joshua Now. * **Where I live**: I still live in Mountain View, CA. * I still live with one small cat named Peanut, who I got in 2021, when I think she was about 1 year old. She is adorable. * **Work**: I'm working as half of a two-person hardware and software consultancy, [Accelerated Tech, Inc.](https://accelerated.tech). * I've been doing digital logic design, and also software. But also a lot of project and product management, because it turns out people rarely know what they need. * **Physical**: I have been biking and climbing a bunch. * I had two shoulder surgeries in 2024. I'm very glad to be back to climbing fake rocks again! It has been a long time in the making! I know a lot more about shoulder anatomy than I ever thought I would. Ask me about it. * I have been [racing cyclocross](https://www.crossresults.com/racer/200270). Even though I am absolutely godawful terrible at it, I love it. * I have been having a lot of fun riding a stupid singlespeed bike around. In 2025, I climbed Mt. Diablo on my singlespeed in 1 hour 3 minutes, which is not bad at all by any standard (though I sure would have liked the hour), but especially good on a singlespeed. My legs hurt the next day. * **Projects**: * I've been working a lot recently on understanding how Bluetooth LE works on a radio level. I bought a BladeRF to try to run Mike Ryan's [Bluetooth sniffer](https://github.com/mikeryan/ice9-bluetooth-sniffer), and this has sort of taken flight as a project -- I have a lot of Jupyter notebooks open decoding radio captures. We'll see how far this goes. * I have taken to experimenting with making things out of DMLS titanium. I've been working (along with [Astosia](https://favouritehumandesign.com/)) on some titanium Pebble watch cases, and also I've been been working on a titanium fountain pen. * I'm on the board of the [Rebble Foundation](https://rebble.foundation/), which takes a lot of my time. * I just finished up getting [X1Plus Expander](www.crowdsupply.com/accelerated-tech/x1plus-expander) into the world! It was a huge project that fully took over my life, manufacturing just shy of 2,000 items and distributing them through Mouser Electronics and Crowd Supply. * I also spent a lot of time in 2024 on the [X1Plus custom firmware](https://x1plus.net) for the Bambu X1 Carbon 3D printer. I think that is winding to a close now. * **Thinking about:** * I would like to learn more about RF and high speed test and measurement equipment. I think it is a lot more expensive than it has to be and I think we can do better. * Some day, I would really like to try out wafer.space or similar and fab out an ASIC of my own, maybe a small 100MHz-class DAC? That seems like it's 5 years out or so but that probably means starting soon. * I have vague aspirations to pick off some Sierra peaks next year. Maybe I should start training.
