lcd module test circuit pricelist

Looking to take your project to the next level in terms of functionality and appearance? A custom LCD display might be the thing that gets you there, at least compared to the dot-matrix or seven-segment displays that anyone and their uncle can buy from the usual sources for pennies. But how does one create such a thing, and what are the costs involved? As is so often the case these days, it’s simpler and cheaper than you think, and [Dave Jones] has a great primer on designing and specifying custom LCDs.

The video below is part of an ongoing series; a previous video covered the design process, turning the design into a spec, and choosing a manufacturer; another discussed the manufacturer’s design document approval and developing a test plan for the module. This one shows the testing plan in action on the insanely cheap modules – [Dave] was able to have a small run of five modules made up for only $138, which included $33 shipping. The display is for a custom power supply and has over 200 segments, including four numeric sections, a clock display, a bar graph, and custom icons for volts, amps, millijoules, and watt-hours. It’s a big piece of glass and the quality is remarkable for the price. It’s not perfect – [Dave] noted a group of segments on the same common lines that were a bit dimmer than the rest, but was able to work around it by tweaking the supply voltage a bit.

We’re amazed at how low the barrier to entry into custom electronics has become, and even if you don’t need a custom LCD, at these prices it’s tempting to order one just because you can. Of course, you can also build your own LCD display completely from scratch too.

Participant must complete an attestation form stating that they maintain a two sided quote in each symbol traded on an alternative trading system registered pursuant to Regulation ATS and display a quotation size of at least one normal unit of trading (specific for each security) thereon. Participants will be audited by Nasdaq, Inc. periodically.

Participant must complete an attestation form and re-certify every six months that they maintain a two-sided quote in each symbol traded on an alternative trading system registered pursuant to Regulation ATS and display a quotation size of at least one normal unit of trading (specific for each security) thereon. Participants will be audited by Nasdaq, Inc. periodically.

Note: Cabinet power cap is based on the available power at 80% of the breakered capacity of all circuit pairs within a cabinet (where a primary/redundant circuit pair is considered a single circuit).

New customers testing services not previously accessed are able to test for up to 60 days free of charge. New customers must notify NTF Billingprior to the start of testing to be eligible for one month of free testing. This includes testing for firms that are accessing NASDAQ through a service bureau for the first time.

NTF metered testing 30-day fee waivers are available to customers pursuant to Nasdaq rules (see Equity Rule 7, Section 130(d)(3) for eligibility). Customers seeking a waiver must register their waiver request with ntfbilling@nasdaq.com prior to the commencement of testing. Customers must provide MPID, functionality being tested, and the desired start date.

Firms will be charged when active testing occurs. It is important for firms to log off once testing is complete. If a firm continues to be logged into NTF but does not send any transactions, the firm will be charged at the applicable weekday or weekend testing rates up to a maximum of one hour after the last transaction was entered.

Please note that the NTF hourly test fees are applied to total connect time. Customers are responsible for monitoring their own test efforts. NTF customers should control all automatic logon sequences and simultaneous login triggers to ensure that CTCI, FIX and QIX IDs are only logged into the NTF while conducting application testing. These rates do not include fees imposed by internet service providers or the dial-up costs associated with modem access.

Subscribers that install the NASDAQ Testing Facility Test Suite or any other NTF dedicated service will not have the ability to alter the nature of their service (a de-installation or installation is required). Subscribers are prohibited from dropping the CTCI, FIX, or QIX portion of the NTF Test Suite at any point prior to the completion of the year agreement. A subscriber that has entered a month-to-month agreement for any NASDAQ Testing Facility dedicated test circuit will be able to uninstall existing service or install new services upon the completion of the term of service.

There is no de-installation fee provided the subscriber has fully completed their term of service. Subscribers that wish to de-install dedicated test circuits before their contract is complete are liable for the remaining length of the contract. MCI requires 30-business days to process disconnect orders.
