Die spamers

Posted on by Brian

Although there haven’t been a lot of recent posts the spam bots are equally happy to crush all the old ones… This made the ratio of spam to real comments explode as of late.

Since everything still is manually moderated, this creates work. To help the situation comments have been closed on all the old posts. If you need to talk about one of them be sure to write using the contact form!

There are things cooking, but I’m not ready to talk about them yet. Stay tuned, it shouldn’t be more than a few weeks before I can give more details.

 

PCB builds

Posted on by Brian

Among the PCBs I got back was a version of BasicUART V2 that uses FT232RL in place of MCP2200. The previous version of this design had a problem with a zone not connecting to a GND pin, which caused it to be flaky at best.

I built up one last night and it worked nicely. I will get to updating the docs and producing a few of these in the near future.

Another design in the PCB batch was a high speed DAC conversion board. This board had some issues. First the footprint for the DAC chip wasn’t correct (I needed the wide version but used the narrow version opps!). Second the opamp circuit was unstable. I was able to hack fixes for both onto the PCB to do some testing. After the fixes the output was not bad at all. It still needs improvement and that will likely require another 2 PCB iterations for what I have in mind to really test fully.

MSPism got a minor tweak to its design, which looks fine but still needs to be tested. I have some firmware written for MSPism but it isn’t what I envisioned as the final features which is why it still hasn’t been released and put on sale. If you feel strongly I should just release what I have done, sound off.

The other boards have yet to be built up for testing of any kind. One of them is for a contract and the other is a new design, for an old idea.

An update!

Yep I’m still here. Quite busy but still working on PCBs and designs as time permits. Just as a short update to wet anyone’s appetite, I got 60 PCBs in the mail yesterday with a few designs among them. In my disarray parts to complete some of them are not on hand this weekend but they will be by next weekend… Stay tuned!

Changes at teho Labs

Posted on by Brian

This is going to be an interesting year for teho Labs.

For those who don’t know teho Labs is currently a one man operation. As a result my free time and how much can be done for teho Labs are intimately linked.

This is going to be a very busy year for me (I am finishing my PhD), to help with my overhead I am going to stop free Fridays for at least the time being.

All of the designs that are available for sale will remain available and as time permits new ones will be added. The same goes for projects such as openHiFi and tehoLogistics.

 

tehoLogistics

Posted on by Brian

I have released a very early alpha of a logistics program for electronics production called tehoLogistics.

The very early alpha quality means crashes are almost certain, but you can get the feel of what the project is like with the software.

The software is open source and available on gitHub, there is also a wiki page where further documentation will be added.

The following screencasts explain the program goals/design and how to use it. Viewing full screen at 720p is recommended for readability.

Finally there is a discussion thread available for this project on Dangerous Prototypes.
