Are any of the programs that John Blankenbaker used to demonstrate his Kenbak-1 (like day of the week

Well, it turns out that the jeelabs' ESP-LINK firmware has a fatal flaw - it disconnects the TCP/

I would order a kit in addition to the assembled one. I would also order a kit of the 1/2 without the

That case looks great! I'm personally a fan of the 1/2 size. Its a replica so a smaller size just

This looks awesome! I LOVE my AW&S Altair 8800. I just ordered a nano and subscribed for updates.

There's also Tom Crosley's assembler written in Python that I use for all my programs now.

If you run this with Mark's new April 8th firmware, it's probably blinking too fast for you.

Ok, I keep typing 3, but it keeps changing to 2. One more try - if this doesn't work... well, you

Wow, that's called support. Thanks Mark, Vicente (Retired EE kind of in love with the KENBAK-1)

All of the beta units were assembled in my shop. I assume the Chinese robot-built units will be more

To answer my own question (ESP-01s are cheap enough to be sacrificial), NO the slight over-voltage

I frequently use manual mode to change the behavior of the data switches. Kenbak-uino Flags (System

I'd switch that back. The "2.2k" on the schematic is a misprint. It's supposed to

Without seeing it, I would suspect a bridged connection under the charge controller (the SOT23-5

So far it's working well. It runs a bit more than four hours on a full charge. I'm still

Hi Chris, nice to follow your progress. I am not sure the MCP73831 Li-Polymer Charge Management

I just saw your eBay auction for the prototype. Very cool! I can't wait for the shipping version!

For all those who kept their breath waiting for the new LEDs, I must say that I am satisfied with the

Oh my... those look fantastic!!! I did mention I want two, right? ;-D Bill On Monday, May 4, 2020 at

I see you added the Lock/Unlock switch. Great! I'll be adding a black, flat on-off switch myself.

Thanks for your help Bill, and for reminding me to always read the manuals. Now that instruction

The last incarnation of the uKenbak-1 used 2.2k resistors for the white LEDs.

Very cool!

I like the shotgun approach - replace everything, one piece at a time until it works. Then you know

Thanks to Mark for helping me to realise my wishes. Now the BCD Clock shows the hour in 24h-format

No. It still exists only in my head and on paper. If I had to guess, maybe summer or fall.
