Sorry for the delay guys, the night after my last post we had one of the worst thunderstorms I’ve ever seen roll through and the power pole outside my house was directly struck by lightning. Luckily...

The ESP-07S modules showed up in the mail today and I started on the first test board. I got the top side soldered this morning and will tackle the bottom tonight.

...

Hey guys, just wanted to update everyone since it’s been a couple of weeks. I was hoping to get the pre-order started last week, however I still don’t have the latest (and hopefully final) iteration...

Possibly, I plan to do some testing with a ESP32 dev board when I’m done with the serial port version. That said, the preliminary testing I’ve done with a TI3200 LaunchPad tells me it would basically...

No worries, glad to help!



Actually, you can! I don’t know if KiCad has implemented this yet, but most EDA tools will automatically neck down larger traces when they go into smaller pads. For...

Okay guys, so there was a major error in RC1B. I forgot to swap CTS and RTS between the RS-232 and ESP sides. Doh! It turns out that’s also why the ESP’s built-in RTS/CTS support wasn’t working in my...

Hey, that Gerber Viewer works fine. So, yeah, first off that power trace is way too close to the edge of the board. You should always check the minimum specifications of the fab you plan to send the...

Ugh... Of course! The pin naming on the ESP is as a DTE... This is why I hate the RS-232 signal naming so much. Having...

Your board actually looks pretty good. Off hand I don’t see any major errors or omissions (there’s a couple of small things, but nothing that would affect operation at this speed level).

Just a...

I’ve planned on doing Modem Emulation as alternative firmware for my RS-232 WiFi SLIP Adapter. It supports *all* 8 RS-232 signals. Though it was originally designed as a SLIP server, modem emulation...

Here’s a PDF of the schematic/layout/figures/BOM for RC1B.

This is the layout (RC1B) I ended up submitting to OSHPark; I made a couple of small changes compared to to the last post (RC1).
...

Okay, Gerbers for RC1 sent off to OSHPark and BOM submitted to Digi-Key! Parts should be here next week.

Routing complete! Here’s some high quality renderings of Release Candidate 1:

@Raven Thanks for looking those up! Let me know how you get on with them under Win 3.x; if not I’ll give it a go this week. (I had it working under 95B, so I can’t see why it wouldn’t work WfW.)

Right, that was the other common method! This is essentially a Voltage to Frequency (V to F) converter. The 555 makes a very practical, inexpensive V to F (what would have taken a dozen or more...

The answer to your question is in the OP. He’s using a modern SATA drive, which doesn’t have an audio output connector. Thus, the only way to actually play music on such a drive is to rip the music...

You’re right, it wasn’t a PD->NDIS converter. I couldn’t find one, so I believe I went about it in a round about way by using a PD to ODI shim and then an ODI to NDIS driver. I’ll have to double...

Yes, right now Winsock applications will work via Trumpet’s SLIP support. Packet Driver based applications can be used under Win 3.x by using the normal DOS SLIP Packet Driver and WINPKT (which...

Awesome, thanks for the support!

No worries, I’d be happy to answer any questions!

Yes, everything is Open Source, including the Hardware Design, Firmware and PC side software. Right now I’m...

You can see things are getting significantly more crowded now that I’m adding...

I’ll post some pictures of the layout itself with contrast enabled so you can see how things line up on both sides of the board, but the short version is I can’t push things up much more than they...

By the way, I hope you guys don’t mind the daily updates. I’m kind of using the thread as a development log. In the past I’ve found people like to follow along as a design like this progresses. If...

There’s no reason I can think of that you’d have to match the mAH capacity of the older batteries. So, you can use a higher capacity battery (1000mAH Ni-Cd are commonly available) to replace the...

Yup, I was thinking the same thing. It should also be an inexpensive solution, too. I can buy 100ct 100mm U.fl cables for $10 off eBay (they have U.fl connectors on one end and are unterminated on...

So, here’s a solution I’ve come up with that I quite like:
