The Motorola 9570 is a portable speakerphone dock made for the Motorola 9500 Iridium phone, and it was also available with an adapter for the 9505 phone. It could fit two batteries for battery backup operation, which is cool.
Unfortunately, there was no power connector pinout available, but I managed to track down a power supply (SPN4645B) and measure the voltages.
Looking at the connector like this:
the potential difference between the left and middle connector is +2.25V, and the potential difference between the left and right is +4.55V.
This doesn’t make very much sense since the PSU lists:
Output: 4.4VDC 3.6A : 6.5 VDC 2.5A
Which suggests that this PSU has voodoo magic going on inside it.
I figured I’d drop a quick promo for my work in the nutrition field outside this blog. This is my nutrition presentation I gave at Google this past May:
I’ve also started a purely for fun venture to investigate the root cause of chronic disease, called Root Causing Health. There’s a great intro of our work on Carnivore Cast here, as well as a Patreon link for those who want to support our lab equipment acquisition 🙂
A lot of my nutrition and health blog-ness will be posted on that forum moving forward.
I purchased the Zoom iQ6 XY microphone for my iPhone to use it for audio recording purposes (I used it as a backup recorder for my recent nutrition talk — at 60 seconds the in-room recording dropped out and I had to switch to the Zoom feed which is why the audio changes at that point).
However, the app that you have to use is so shitty that it doesn’t provide a way to copy the file off of your phone. It provides:
Email functionality: app won’t let you email files larger than 25MB.
Sound Cloud export functionality: soundcloud doesn’t accept large files in uncompressed format.
If you’re like me, you discovered this after making an important recording and now need some way of accessing your files.
Use a backup explorer
I installed a backup explorer which allowed me to view the files that each app stores on the phone.
Connect your phone over USB to your computer, authorize computer etc.
Open the backup explorer. (You don’t need to make a backup for this)
Navigate to the HandyRec app folder.
You should see the WAV file that you recorded inside this folder.
Copy the file to the computer
It’s a bit of a brutal hack but it makes this app usable. I would think twice about purchasing this device if you haven’t already due to this limitation, but I will admit that it’s handy.
I’ve been a film geek for a while, and one of my bucket list items was to shoot on real motion picture film. When I saw that I could apply the Intro to Film-making course at the SMFA to my engineering degree, I decided to take the plunge. The class was actually a nightmare to attend, mostly due to its distance from the main campus requiring 40 minute bus rides every Monday with a heavy-footed driver, the timing leaving little opportunity to get food during my already-packed Monday schedule. But it was quite fun! Continue reading 16mm film! Experience with Cinelab scanning my film school project
When I was a wee lad I followed Ken Rockwell’s website. I always used to salivate over the more expensive Nikon lenses as I puttered around with my kit lens on the D90, a crappy 70-300mm tele that ended up stolen, and at long last at the end of high school an 80-200mm F2.8 AF-D.
