Added lights to my Caldwell Ballistic Chrony
« on: October 20, 2018, 03:17:17 PM »
Just a little project to work on a hot afternoon.

I had been having a few 'errors' with this chrony, typically in the late afternoon which is when I usually shoot. Where I shoot from is under a shade tree and when the sun gets low It gets some 'dappled' sunlight which is probably the issue. I had seen another forum member had just stuck 'tap lights' on his chrony and the light went off.. if you pardon the pun.

Here is everything I needed. The chrony of course, some tape light (on the black spool) left over from previous projects, some wire, a couple of alligator clips, and a 9 volt battery.

I soldered some wires (stripped from cat 5 cable that I have) onto the little copper pads of the tape light. Mind the polarity :)

The tape light has a self adhesive on it so I just stuck it to the underside of the shades.

Wired it all together minding the polarity, put some Velcro on the 9V battery and that's about it.

Lights up nice and steady!

Does it work? No idea  ;D haven't tested it yet but it should. I will get a chance to try it out this afternoon once it's cooler and I will report back on its performance, and battery life.

They draw around 75ma so by my calculations it should be around 6 hours of battery life.

Thanks for looking!

Any arrangement that works is good.    I had first tried the blue HF puck lights but saw too many ERR's.   Since I use the chrony exclusively indoors, I went with an IR light set.   The fact that a double discount and free hat got it down to about $40 helped too.    :D

I did not get a chance to test this today.

I waited till late afternoon, then rain, then it was time to cook some burgers on the grill. After that it was still raining. so, there is always tomorrow :D

I have lights that I'm guessing are similar to the HF lights you have, mine came from the bargain bins at WM. With mine I ended up getting the best results by using them on top of the diffusers, shining down through them.

ETA- It's a C E ProChrono Digital.

I thought about that and may still go that route putting the lights on top of the diffuesers.

Thought I should get back to this and report... it did not work. Error 3 every time :(

I will have to try it with the lights on top of the diffusers and get back to you.

Well I got a chance to try it with the lights on top of the diffusers and now it works quite well.

2 dozen rounds, no errors, and it is a grey overcast day out.

Think I will re-do the entire thing to make it a little less sloppy.

Great thread Tom. I'm glad it worked out for you.

I have the same unit and now I have more options to use it thanks to you.

Thanks for the updates and the idea.

I started out with the Harbor Freight blue LED lights on top of the diffuser and they worked ok, but switched to a slightly different style HF puck LED light and they work even better.

HF - Is that High Frequency?

One puck centered over the arch, or multiples spread across?

Here's mine.
12V automotive led strips off Ebay. Cost $6.49 pair. Wired them up in parallel and running off a home made regulated and filtered 1A 12v dc power supply. I built the power supply about 30 years ago for a ham radio project. Any 12v battery will work too.

These lights are very bright and the Competition Electronics DLX works great with them.

I used the same LED strip as you but put two rows on top of each difusser and staggered them.  I should probably try just one row like you so I don't need the plug in power supply to drive it and can just use the 9v battery.  Much more portable.

For a while I used a light bulb above the sensors of my chrony for indoor work and in general it did OK. After moving to North Carolina I started setting the chrony on the roof of my sun room through a window at my "man attic" like this............


Well, a few years ago I bought a factory chrony light for my ProChrono and I've been using the light ever since with no errors as long as the muzzle is placed correctly...........

How do you word it... "Air Guns" or "AirGuns"?
