Hi all,

I just wanted to let you know that the order was sent in, and the boards are in the manufacturing process now. I anticipate them arriving to me by mid-May, whereafter I'll start programming and shipping them as soon as I can. I hope to have everything delivered to you by the beginning of July (keep in mind I try to give my time estimates like Scotty of Star Trek fame<https://www.youtube.com/watch?v=t9SVhg6ZENw>).

If you're coming late to the party and would like to order one or more boards or want to change your order, let me know. I ordered about double the boards that were requested of me, and even with some orders I had come in after the fact, I will still have around 40 boards in stock to have on hand for the future.

The final price, including shipping (except for those who are outside the continental U.S.-- sorry, shipping will most likely have to be a bit more) will be $35.00. If you want to get ahead of the game, feel free to use any of the following methods whenever is convenient for you:


  *   PayPal: send to js at teletype.net<mailto:js at teletype.net> (if you use the "Friends & Family" option, the transfer is free for me, otherwise it'll cost me a little over a dollar per transaction; any excess funds that come from this venture I will immediately be reinvesting in teletypery, though I don't anticipate a lot of excess after everything is said and done)
  *   Google Wallet: send to weildish at gmail.com<mailto:weildish at gmail.com>
  *   Check- let me know if you prefer to send cash or check in the mail-- I'm willing to acommodate that if needed
  *   I should have one more option available (credit card) sometime later when I have time to set it up in a couple of weeks. That will also cost me around a dollar per transaction, but I want to make this as accessible as possible to everyone.

Thanks much for the immense interest, everyone. I'll keep you apprised.

Hello friends,

I will be doing a manufacturing run of the USB <--> Current Loop boards after Eric Volpe's design<http://heepy.net/index.php/USB-teletype>, and I will be taking orders for anyone who wants one or multiple. Use these to interface your heavy metal machines to modern computers and exercise them more than they otherwise would be. See some machines in action with these boards at https://nerdology.org/youtube. Every teletype-related video there including the RTTY ones shows my machines being driven by these boards.

I should be able to ship the boards to you for no more than $35-$40 per board, which covers the board, continental U.S. shipping, and any shipping/packing materials I need to invest in. I might be able to do it for less, but I will get things finalized and let you know.

Please email me off list with the number of boards you'd like so I can gauge the overall interest and know if I should order more/fewer boards. Even if you already emailed me before about this, please do so again just in case I lose your previous message from last year.

Let me answer a few questions people may have ahead of time; more details to come:


  *   I'm outside the continental US-- can I make an order?

     *   Absolutely-- shipping will probably be higher, which I will deal with on an individual basis.

  *   When will the boards be ready?

     *   I'm hoping to ship by May, 2019. Maybe June if I'm slow.

  *   How will funds be collected?

     *   I'll probably set up an account with Stripe or Square to make it easier on myself, though I'm happy to take payment via PayPal or Google Wallet as well.

  *   Will [X] teletype work with this board?

     *   Any 5-bit machine running on a 20ma/60ma high voltage current loop should work. 300 baud should be easily attainable-- possibly much higher speeds.
     *   ASCII machines should work, too

  *   Is a power supply included?

     *   No. You'll need your own PSU with appropriate current limiting resistors to power the loop. I've used a prebuilt one from China that has served me very well driving multiple loops at once. There are other options, too.

  *   Will this work with [X] computer?

     *   I'd recommend investing in a Raspberry Pi to be your teletype controller, but any computer with a USB 2.0 or better interface should work, including but not limited to ones running Linux (any *nix, really), MacOS, and Windows.

  *   What software do I need to use it?

     *   Pretty much anything that can manipulate a serial interface. There are a number of options that should work, or you could roll your own. I will probably write up some details on the range of options when I get a chance. I have been rolling my own for a while-- it's not quite user-friendly enough that I'd want to release it yet, but I'm working on making it public.
