Morning out with the girls

Reprap gets going

Here are a couple of iPad stands, which need a cross bar the hold them up, but otherwise work well. The design comes from the web site thingyverse:



And this stand along, but rather chunky design:



UNFORTUNATELY

The hot end extruder has developed a leak, and hot plastic dribbles down the side, spoiling future prints. Later… this has been fixed, had to take it off the carriage and tighten it in the heat insulator tube. All now seems well and I have started printing again.

A better SDR Ham radio setup

I have been looking for a while at the conventional ham radio setups. They look like this:



The ATU and TXRX are in the shack, with a long cable to the antenna. The ATU and TXRX can be integrated.

The SDR and ATU are integrated. And the control is by WiFi. The box is placed at the base of the antenna. No long feeder cable, in fact no cable at all, except for the need for an AC supply, or maybe a rechargeable battery? The system can be controlled from either a PC, or from a mobile phone or pad. You could offer others to log into a server and for them to control the system?
