DIY: Add a USB cable to Broadcom BCM92045NMD Bluetooth module

This can be done to add bluetooth devices to a PC that doesn’t have bluetooth capability. For this adapter, I could only found a clear pinout in Chinese (I think), here: So here is an english version, in case anyone needs it.

The main picture you need, in case that site goes down:

I used 3 diodes (that I had previously measured at about 1/2V drop each) in series, to burn a volt and a half-ish, instead of using a proper voltage regulator. I only wired up the first four pins (8, 7, 6, and 5) instead of joining all the ground pins (3, 2, 1) as shown in the diagram. I used a pretty janky method of soldering too:

so do better if you can. I’m going to drown this in RTV silicone to keep the wires from touching, so it’s going to look even worse in a few hours(!). This prject would have been easier if I had the proper cable to connect the Bluetooth module to a laptop, but I didn’t. I gently broke off the top of the connector and tinned the pins right on the board. Soldering to those pins was *tricky* as they are tiny and very close to each other. After the all-important “nothin’ touchin’ nothin'” inspection, I plugged this mess into a handy open USB port on my PC and Windows automagically showed bluetooth capability. It connected to my BT device with zero difficulty.

N.B.: without the cable I had to make several tries at this. I destroyed 3 connectors (wasting three adapters) before figuring out how to chip off the plastic. Use a small awl or flat-head screwdriver and pry the top of the connector shell directly away from the PCB, between the pins:

Wish List ~or~ what even do you want?

I have previously posted a wish list that included modestly priced items, mostly books, for people to find something to buy me.  It had no links and was not maintained.  Well here is one with links to purchase items, and my self-imposed restriction on expensive (for my budget) items is lifted.  Prices where listed are full-retail prices as of September, 2020.  Buy one, buy all, or buy none and wish me a nice day, I’ll be happy either way . . . but if you want to buy me something, here’s a list from which you may  choose!


Nikon D7500
with lens in a kit $1849
Or in a kit with a different lens from B&H $1200
or with any lens combination, or without lens, body only new $996
Refurbished by Nikon from a Nikon-authorized dealer is perfectly fine, I’ve bought a few things refurbished from authorized dealers and it’s always been good. . . and cheaper than retail new if you can find it . . . here’s just the body for $700

or the D750
With lens $1996
without lens $1496

Still camera related with fewer numbers after the $ haha:

I’m not married to a brand or model, and I’m not a stickler for shiny-and-new.  Click a link or find a used working one and I’ll be good either way!

A small mill

A router, preferably with a cord (vs. batteries):

Albums (well, compact discs):

Joe, All That I Am

Alanis Morisette, Jagged Little Pill

Josh Turner, Icon


Cranberries, To the Faithful Departed


A guitar. If I’m picking, I’d take an Ovation with a deep back, preferably with a round sound hole as well as an integrated pickup.  Add in a magnetic pickup for the sound hole if you feel like it. Surprise me with the model and style!  If you just can’t avoid a shallow-back Ovation or one with the Adamas style of sound holes, that’s ok too. If you happen to have some other flavor of guitar, send it! I have a small variety of guitars already and one more different kind will be welcome.

Buck model 182, 181, or 186 folding pocket knives, preferably with 12c87 or ats34 steel blades.  They are discontinued a long time ago but still pop up on ebay.  Other knives will pop up when you click on ebay but the ones I want all look like this  ebay search link:


Any flavor/color/material variant of a Walther P22

Any variant of a Heritage Rough Rider

Any variant of the Ruger MkIV 22/45

Any amount of any sort of ammunition in .30-06, 7.62×39, .40 S&W, .380 ACP, or .22LR

Books, in no particular order. Soft or hard cover, used or new, so long as it’s on paper!
