Modded my Trustfire TR-001

[nahoku]

Since I no longer intended to use my TR-001 to charge batteries anymore, and I was also getting really tired of pulling out my voltmeter every time I wanted to measure my batteries, I decided to mod the TR-001 into a meter. I also added connectors so I could measure battery voltage on my mechanical mods while loaded or unloaded.

Basically, the TR-001 was gutted (all components removed), holes were cut for the meter, a switch, and the two 510 connectors, then everything was installed and wired up. The meter and top connector was purchased from Madvapes. The bottom connector was from an old DC cartomizer, and the switch I already had. It's a very simple DIY for those who can work this sort of thing.

Madvapes is currently out of stock of their Ohm-meter module, but I plan to install one later so this thing will also read delivery device resistance.

All in all a good mod so far, and IMO the best way to utilize an unused / untrusted / unreliable / POS TR-001!

Wow. Pretty fantastic stuff. I just happen to have an old TR-001 that currently resides in my bottom drawer.

Maybe a good project for a Saturday afternoon. Doing something like this never occluded to me before.

That is REALLY cool. I have a TR-001 I don't use anymore but I don't have the skill set to put that together. It is a good idea though.

Yah, that's where I had my TR-001 too. I was about to throw it out but luckily thought about this before I did.

If you know someone who can solder a little, this is quite easy to build. I can put up a drawing (schematic) if it would help. Very simple stuff really.

Note that since this is ABS plastic, drilling is NOT recommended. The plastic can grab the drill bit and may start cracking. Rather than drilling, the plastic was pierced with a hot soldering iron (small tip) to take out the bulk, then trimmed (Xacto knife... be careful!), and then filed to fit as required. Takes a little work, but not at all hard to do. Best of all, nothing cracked!

Looks great! I also happen to have one laying around that could use a little purpose in its life. Thanks for sharing.

Great idea....I just happen to have an old charger like that as well....

Why not just put the battery in your Vamo and check the voltage?

Been there, done that!

I have 12 batteries, 4 of which are 18490's that need spacers for the Vamo to read them. This is way faster than using a Vamo. Plus way cooler!

I am reading this on my phone, so forgive me if i missed it. But i would appreciate a schematic if no one else does.

I decided to create a blog entry for this mod. You can find a down-loadable PDF which includes a schematic and writeup of the project in my blog.
