I test each and every one of them for 30-45mins and I've never heard anything like that. I wonder if your particular clock is picking up something from some other nearby electronics with a conflicting frequency

2018.nov.12 update
only one reservation spot left in the list the pattern is full ghost rider

everything except the acrylic frames has been ordered (I never know what changes will happen to the LED panels until I receive them, so I usually hold off ordering the frames just in case there is a change

I still have enough hardware and shipping boxes from the last batch to accommodate this batch (finally, a little forethought on my part

data and power cables will be assembled once the panels arrive (again, small changes can change the lengths needed, so there's no sense in putting the cart before the horse

edit: all spots are now taken

2018.nov.16 update

2018.nov.19 update
- took care of scottyc
- LED panels have shipped, ETA is wednesday
- run-dmd boards have hit customs in the usa (ny), ETA is friday
- power supplies received today

if all goes well, I should be able to make any necessary adjustments to the frame patterns & order the laser cut acrylic before the end of next week. as long as ponoko isn't overbooked, acrylic should arrive within 10 days of ordering and then assembly & shipping can begin to allow everything to reach its destination well before the holidays

2018.nov.21 update
- LED panels arrived today. need to determine if a frame change is necessary
- run-dmd boards are scheduled to arrive on friday, nov 23rd

- laser cut acrylic frames will most likely be ordered on friday
- power and data cable construction will commence this weekend to stay ahead of everything

2018.nov.23 update
- run-dmd are on a usps truck for delivery today
- acrylic frames have been ordered

to do:
- construct custom power and data cables this weekend
- assemble and box up clocks once the acrylic arrives

note:
I'm still looking for mailing information from a few people (see the initial post) if I don't have a [C] next to your name

I may offer up the kits for the standard size dmd's again after the holidays. I ran them 2x before but did not have too many people that were interested in them. the problem being that even if you supply the dmd yourself, the cost of the kit was like $300 for the rest of the components. I think that if I do decide to offer them up again, I will do so strictly as kits without the displays. I'm not sure if they will run with the older gas plasma displays, but I do know that they run with the newer stern LED displays

see above

2018.nov.26 update
- completed assembly of the power cables (mantra during this phase was "I really hate cutting wire, then I really hate crimping" and then, "damn it!, I forgot to strip all of these wires!!"
- ordered acrylic frames

to do:
- assemble and modify the data cables (to accommodate for the [purple] issue
- pre-assemble shipping boxes

acrylic frame delivery ETA - friday, nov 30th

clock assembly will begin this weekend and invoices issued on sunday or monday

edit:
this has got to be the quickest turn around that I've experienced to source items from hk, california and the netherlands in only 20 days. it's a xmas miracle!

2018.nov.28 update
full disclosure. I'm an idiot

when I put together the last batch over the summer, the LED panel vendor mentioned that they were changing the frame design (once again) and I had asked him to send me a blank frame so that I could compare it and make any necessary adjustments going forward.

apparently, I didn't do that and had completely forgotten that they were different because when the LED panels arrived last week, I compared them to the empty frame and said "yep, they're identical"

fast forward to last night where I decided to construct a single clock with extra rear panel of acrylic that I had since all my other prep work for this batch was complete) and that's when I found out that the lug pattern had changed again. and while it wasn't enough to notice at a casual glance, this 4mm change in the distance between the top and bottom lugs is enough that the screws no longer line up to fit through the holes on the rear panel

to correct this, I've made the adjustments to my design and re-ordered 24 additional rear panels from ponoko late, last night. I have an initial ETA for this new order of next tuesday, december 11th.

in summary:
a failure on my end has resulted in a costly mistake and a slight delay in being able to assemble and ship the clocks to everyone on the list

I may end up attempting to re-work them for a future batch. I have a friend with a cnc that should be able to elongate the (8) holes by 2mm each. if done properly, the washers on the screw headers will probably cover everything

2018.dec.03 update
the replacement rear acrylic panels are due to arrive this friday
if everything goes according to plan, assembly will start this weekend and invoices will be sent out on dec 9th/10th.

I think that I still need address information from 1 or 2 people to make shipping go a bit smoother, so I will reach out to those people today

2018.dec.05 update
good news everyone! the replacement acrylic has shown up 2 days earlier than expected
I've started assembly this evening (8 completed) and should have all clocks built, boxed up and ready to ship by friday or saturday

invoices will be sent tomorrow and clocks will be posted out on a first paid, first shipped basis as soon as I have them ready to go

2018.dec.06 update
all invoices have been sent as of 8:00am EST if you did not receive a pm with the total amount due and how to make payment, please shoot me a pm

assembly will continue tonight and should wrap up tomorrow or saturday. all clocks will be boxed and ready to post out on monday, dec 10th

2018.dec.06 update 2
it appears that I currently have one clock still available (in addition to one that Londonpinball has expressed interest in), if anyone is interested. the 2nd non-pinsider has prior commitments and has backed out

assembly for 8 more clocks were completed tonight. the remaining 8 will be assembled tomorrow and all currently paid clocks should ship tomorrow or on saturday

I've decided to air out my grievances and you all have to defeat me in a showing of the feats of strength to receive your clocks

2018.dec.07 update
- all clock assembly is complete
- clocks have been bubble wrapped for shipping

boxing willl commence after lunch and I hope to ship all paid clocks today

2018.dec.07 update 2
all paid clocks have been packaged, postage labels printed

I'm now heading up to the post office to beat the 7pm cut off and ship as promised

why does everyone change it to 'red'?!? purple, teal, blue and/or green are much nicer looking colours in my opinion
I may have to start shipping these with the red switches broken
