Are you in New York? What are you doing this week? Hackaday is having a party on Wednesday evening . come on out!

How about a pub in Cambridge? Hackaday and Tindie will be there too , on Wednesday evening. It’s a bring-a-hack, so bring a hack and enjoy the company of your fellow nerds. If this goes late enough we can have a trans-Atlantic Hackaday meetup.

Portable emulation machines are all the rage, and [Pierre] built one based on the Raspberry Pi Zero . It’s small, looks surprisingly comfortable to hold, and is apparently it’s fairly inexpensive to build your own.

For the last year or so, the Raspberry Pi Zero has existed. This came as a surprise to many who couldn’t buy a Raspberry Pi Zero. In other news, Ferraris don’t exist, and neither do Faberge egg omelets. Now, the Raspberry Pi shortage is officially over. They’re in stock everywhere , and we can finally stop listening to people who call the Pi Zero a marketing ploy.

No Starch Press is having another Humble Bundle . Pay what you want, and you get some coding books. They have Python, Haskell, and  R , because no one should ever have to use SPSS.

[Reg] wrote in to tell us about something interesting he found while cruising eBay. The used and surplus market is awash in Siemens MC45/MC46 cellular modem modules. They’re a complete GSM ‘cellular modem engine’, with an AT command set, and cost about $10 each. Interfacing them with a board requires only two (strange) connectors, SIM and SD card sockets, and a few traces to through-hole pads. Anyone up for a challenge? A breakout board for this cellular modem could be very useful, should someone find a box full of these modules in a surplus shop.

On this page , about halfway down the page, is an LCD driver board. It turns a video signal into something a small, VGA resolution LCD will understand. This driver board is unique because it is completely hand-made. This is one of those small miracles of a soldering iron and copper clad board. If anyone out there is able to recognize these parts, I’d love for you to attempt an explanation in the comments.

A few weeks ago, the RTL8710 WiFi module showed up on the usual online marketplaces . Initially, we thought it was a competitor to the ever-popular ESP8266, offering a small microcontroller, WiFi, and a bunch of useful output pins. A module based on the RTL8710, the RTL-00, is much more than a competitor. It’s pinout compatible with the ESP8266 . This module can be swapped into a project in place of the ESP-12, probably the most popular version of the ESP8266. This is genius, and opens the door to a lot of experimentation with the RTL8710.
