That sounds interesting, you need to post a picture of you wearing it when done Smile

Also LED's will be the next part of my project to tackle once I have this screen etc working.

TBR, I know you know this, but I think you're a little bit of a genius!

I've been ill for a good few days now so no real progress has been made, this evening I tried to wire up the ADC to my Pi to measure a 9 volt and it didn't seem to be doing it correctly, so I'll have to give it another bash tomorrow.

A few pics for those interested.

Pi all wired up

Closer look at the resisters

I also ordered this that I may use instead of the loose chip as I think wiring will be simpler but I haven't wanted to get the soldering iron out to sort it.


So I plugged in a 9 volt and ran an example script that simply displays all the chips pin inputs, nothing seems consistent, I would assume pin 0 would have a single repeating number while the others were showing zero.


EDIT:
Just realised I hadn't posted about last weekends work before I got ill, so before today's update here's last weeks.

So I started to put the internal ribs inside the blaster to support the lopsided internal stryfe shell. I really lucked out with some square styrene tubes that were exactly the right width.




I also filled in the long thin holes in the side with some thin styrene strips with epoxy putty over the top, this will be sanded down nice and flat when the time comes.


Now for this week!

It was finally time, I couldn't put it off any longer, I had to attach these two shells together. I used Devcon to attach one shell to the ribbing I attached last week and on the other side used it to directly attach the stryfe to the centurion shell. I was really careful to make sure everything stayed lined up so that the two shells would go back together. Once the Devcon had some time to dry I went round various parts of the joins between the shells with epoxy putty to strengthen the connection. I also started to fill in some of the gaps in the handle area too.



Once I had finished the epoxy putty work I put the shells back together to make sure all was good...

All wasn't good, somehow I had managed to nudge something and they didn't go together....

DAMN!!!

So with some pushing and twisting and a little bit of praying I managed to get the shell halves together. To try and make sure it all stays this way I have now wrapped the blaster in string while it all drys and hopefully all will be good, if not I'm going to call the samaritans. :/



EDIT:
The wait is over....a new post has appeared!

So has the blaster survived? The answer is yes! I haven't managed to get as much done recently as I had hoped, that's the nature of Christmas and family.

My blaster is now together and I have created and sanded smooth the joins in the handle and the thumbhole stock area, I'm quite pleased with how this has turned out. What I'm not so pleased with is the fact that when the two shell halves are together the internal Stryfe shells at the front have about a 1-2mm gap between them. I'm hoping it's not a big issue but we will see about that later when I've got the internals in place. I have a spare Stryfe if I need to remove the current Stryfe and try again but I really don't want it to come to that as it's Devcon'd in and that would be a nightmare of a job!









I have also cut out the plate I'm going to use at the front of the blaster to cover the big hole, I'll get to fitting that in a few days I hope.

The internal electricals are all put together and working, they are not inside the blaster yet but the display shows darts left, total darts fired and current battery voltage (9v at the moment for testing). Theres a lot of wires to achieve this but luckily the blaster has lots of room inside. Unfortunately I can't directly attach the Zero LiPo Hat to the GPIO pins on the Pi as I had planned as it blocks access to the I2C pins used by the ADC to detect the voltage. The OLED Screen is also running off SPI and not I2C as I couldn't get it to work so its using 4 wires instead of 2.

What I really like is that those last two sentences would have made no sense to me a few weeks back, lots of learning for me with this project!



EDIT:

Things have been quiet here recently and that has mainly been down to the weather. It's coooooold!

When you have to go out into the shed in temperatures around zero its hard to stick around and get much done, but the last week or so hasn't been too bad so work has commenced.... kind of.

I've done what I thought I might have to do and unfortunately start the shell work again from scratch.

Even though my thumbhole stock was beautifully comfortable and the join between the two blasters was smooth, the missaligned internal structure was just too much for me.

I was building a replacement front end for the blaster using styrene/putty/devcon and it looked great, I smoothed all the edges and made it nice to hold but while working on this with the stryfe's barrel sticking out the front it was made more obvious how out of alignment the internals were. It's not good when your barrel is easily 10 degree's off from straight.

Now I could have carried on, there's nothing actually wrong, it's just not straight. I know though that it will really really irritate me that it's not straight and after watching a video on reddit of a guy spending two years building a stryfe/stampede integration and starting the shell work again I decided that yes, this was what needed to happen, I need to do this right.

So shell integration v1 is now being thought of as practice, I've learnt a few things from it's construction that should hopefully make v2 better or at least make sure that things are straight this time!


EDIT

Please don't double (or indeed quadruple) post. This one was a pain in the arse to merge and tidy up. Factoring multiple posts is a moderation nightmare and risks me losing content when I do it. In future, please be sure to edit posts or copy old content into new posts if you want to bump a thread. -Boff

I'm really glad you bumped this! I forgot I read it before and just enjoyed reviewing it! Love the idea!

Apologies for the quadruple posts, I had assumed due to the nature of the thread being a time based follow along project, that multiple concurrent posts would be ok as it's showing a timeline of the progress accompanied with the time stamps of the posts. I'll stick to the usual rules from now on.

So last night, while listening to the discord chat, I was in the shed hopefully doing the last of the major dremmelling to get the version two progressed. And I seem to have done it, the Stryfe is inside the Centurion and it all appears to be straight. I haven't done any actual bonding I simply used sellotape but the theory appears sound.

Also today Raspberry Pi released a new version of the Pi I'm using that has built in WiFi and Bluetooth so that's going to make things more compact as I won't need to have a usb wifi dongle hanging out the side of the Pi, even though there is lots of room in the centurion stock I don't want to take up unnecessary space.

Tonight it's cutting and sawing various styrene tubes to fill the gap inside the centurion shell due to the lopsided stryfe body.

--------------------
- March 9th
--------------------

I've been in contact with a company that Chromes various things, after a quote to get this blaster chromed. As I had no idea what this would cost I was just after a ballpark figure, well 120 I was quoted, a bit rich for my blood but an interesting bit of information.




--------------------
- April 10th
--------------------

I'm right in the middle of my busy period at work so things have been even slower than usual, but progress has been made.

Most of the Stryfe has been Devcon'd in place within the Centurion and importantly it's looking straight, thank goodness for that as I really didn't want to have to start a version 3, and to be honest I wouldn't have.

I soldered up the electronics to the simple mounting plate I had made and it didn't work anymore, somewhere my soldering had let me down. I also then found after I got things working that I had managed to bugger up the OLED screen so every other line in the display wasn't working, now waiting for a replacement to arrive as I can't tell if things are working correctly or not without it.

It still visually looks like nothing has really changed in over 6 weeks or so now. Ho-Hum


--------------------
- April 12th
--------------------

New screen arrived and it all works! Easter weekend is this weekend so I hope to get a lot done, fingers crossed!

--------------------
- April 19th
--------------------

Managed to figure a few things out and I've also got a chunk of the soldering sorted, just waiting now for the arrival of a few more JST connectors for wiring up the other buttons so I can disconnect them when taking the shell apart or removing the internal electronics mounting etc. Havn't shrunk the heat shrink yet just incase there is an issue.
