90 Degree UHF Connector
Good product. Quickly solves some close-clearance issues behind equipment where space is limited. No appreciable adverse effects to signal quality in HF range from my own experience.

Main Board Screws
1 von 1 finden das hilfreich Great product offering! While these can be adapted to other uses, these are jack-screws for mounting PC main boards in cases. Overall, many PC case mfr's are moving to optical drive screws for main board mounting and abandoning the traditional #6-32 PC screw used for time immemorial. These are the same jack-screws many case mfr's are now using. Some only offer six jack-screws for Mini-ITX boards while others need two or more for Mini-ATX (mATX) or full size ATX main boards. Can't go wrong with these paired with the M3x6.5mm optical drive screws available. Glad to know somebody out there has our backs!

Vintage Style Nixie Clock for every Vintage Buff
This vintage style clock uses the power line's frequency of 50Hz or 60Hz depending on the option you install. You get a very good quality PCB. There are no assembly instructions but then, if you don't know what you're doing, don't buy it. You can download a file with the current schematic, component outlines for front and rear as well as the original schematic this was built off of. A second file contains the Bill Of Materials (BOM) you can order parts with. There are a few parts that aren't available where this document states but they can be located elsewhere. I highly recommend you get his parts package and Nixie Tubes as you may be hard pressed to locate them in North America. I bought mine from the Ukraine and it took six weeks.
This is a Line Sync clock and will be quite accurate as long as power is on and stable. Once the power glitches or goes out the clock will have to be reset. There is no provision for battery back up as the entire board makes up the clock circuit using discreet components.
Caveats are the surface mount type capacitors but with 2.5x reading glasses and a 30watt fine pencil tip soldering iron, you can solder these in place.
The unit works great but with power dips the clock does fall off often. Best to use a power conditioning or regulated AC power supply recommended by the Bill of Materials list. I do not recommend using a modified sine wave uninterruptible power supply as the pseudo sine wave contains sharp rise and fall slopes that will confuse the counter. Use only True or Pure Sine Wave inverters for continuous use. Also recommend to use the pin sockets for the Nixie tubes as defective tubes can be replaced much easier.
The clock shows the warm glow of neon from technology derived from the 1930's on through the 1980's. Useful as a learning tool on how discreet IC's work as you build and study the schematic.
Kit difficulty is at least intermediate level.
