Eyesight and SMD (was Re: [neonixie-l] PV clock kit - word of caution)

I'm not afraid of SMD, I just can't see well enough and my hands shake when I'm 
stressed out. I have several kits sitting here waiting for the day when I can 
sit down and work on them comfortably, whenever that will be. Building kits is 
supposed to be fun and the fewer fiddly bits the better. For me the main 
advantage of a kit is that it's cheaper and having all the SMD already in place 
really greases the skids.

OTOH, if you're comfortable with SMD work more power to you. As for myself, I'm 
highly myopic and I used to be able to see things VERY close up. Now that I'm 
in my late 50s presbyopia has robbed me of my near vision. Furthermore, I have 
strabismus which causes my eyes to fail to converge properly and create a 
proper sense of depth. For me it's poor at a distance and improves as I move 
closer to an object but then just as I'm almost there everything starts to go 
out of focus. A binocular microscope wouldn't help me because when I look into 
one it's the same as looking at something in the distance so I can only use one 
eye at a time.

When I was a kid I didn't realize that when you looked into a ViewMaser you 
were supposed to see a stereoscopic image. Later in my teens I found some reels 
for sale that were old stereoscopic pictures from the 19th Century. I bought 
the ones with trains, stuck them in the ViewMaster, and with great effort 
finally managed to see something in 3D for the first time. I was probably 15 or 
16.

Needless to say I'm not a big fan of 3D movies. The only one I've seen 
(partially) was Werner Herzog's Cave Of Forgotten Dreams and I had to sit in 
the front row to even...well, I forgot to mention that my glasses have such a 
low (negative) power that they make everything I see MUCH smaller than life 
size. Objects appear smaller than they actually are, to borrow or perhaps 
mutilate a phrase. And because my retina is stretched out slightly the neurons 
in my fovea are farther apart than normal which reduces the acuity of my sight 
even further. 

I used to be able to glance at a resistor to read the value. Now I HAVE to use 
an ohmmeter to be sure. And yes, I can see well enough to drive even at night. 
I have a very good ophthalmologist.

I hope this doesn't sound too much like a rant. As I said if you're comfortable 
with SMD work more power to you.

Do you want to hear about the floaters?

Yes I did send an email to PV detailing my concerns. I am currently
underway with the rest of the build and it is progressing smoothly. I have
no doubt that it will be another great nixie clock to enjoy for many years.

My intention here was to encourage others to double check their kits before
proceeding with the build. It is much easier to spot and fix this before
populating other components.

Re: [neonixie-l] Re: PV clock kit - word of caution

2019-07-20 Thread Kevin A. 
Nick,

As far as I can tell, there are no two adjacent circuits that should be
bridged on an HV series serial to parallel converter. I've implemented this
chip in several of my own designs.

(Unless its a bodge fix for a board layout error, in which case the board
should be fixed before being sold as a working product)

For hot air rework, the Quick 861DW is the best value in my opinion (not
affiliated with quick). It competes with stations over twice the price. EEV

I think 87.8% efficiency is great.

As far as soldering SMD stuff, get some solder paste and a hot air rework 
station. It makes short work of those things. Also a magnifying head set for my

You may want to check that the bridge isn’t deliberate before removing it.
While, I agree with the spirit of this statement. If you look at my photos they 
do not appear to be bridged at all. There is just solder debris between the 
joints that could present an issue.

[neonixie-l] Re: Power for six (6) GR10G Nixies: 300VDC @ 40mA - small switching PSU?

2019-07-20 Thread newxito 
 

I did a short test with the components shared in “yet another nixie power 
supply”, just changed the output caps (450V) and the voltage divider.

It worked ok with 300V/40mA, the efficiency is not great but ok, 87.8% with 
12V input voltage, the transformer temperature stabilized around 42 ° C.

Unfortunately the LT3757 is difficult to solder, I always need a lamp with 
a magnifying glass. I think there is no trough-hole version.

Maybe its just honest what you get. Usually drives are smaller than 
advertised. Alot of people use 1Gb = 1000Mb, but in reality its 1024 Mb! 
And then there is space for the filesystem reserves. I ordered a 6TB HDD 
last week which is ony 5.4 TB in reality (i knew that, its very common)

Just ordered one. Will let you guys know about the malware. Of course, I will 
be trying to take it apart to see how it all works, as I did something similar 
recently. https://youtu.be/ofePAvFkGZs
